ASIANEWS MDBS’ CLIMATE FINANCE IN LOW- AND MIDDLE-INCOME COUNTRIES REACHES $41.5 BILLION IN 2019 Cli mate financing by seven of the world’ s largest multilateral development banks (MDBs) accounted for $61. 6 billi on in 2019, of which $41. 5 billion (67%) was in low- and middle-income economies, according to the 2019 Joint Report on Multilateral Development Banks’ Climate Finance.

The study expands the scope of reporti ng for the first time to all countri es of operation. It now provides data on MDB climate finance commitments beyond those directed solely at developing and emerging economies, but with the focus remai ni ng on low- and middle-income countri es. The 2019 report shows that $46. 6 billion – or 76% of total financing for the year – was devoted to climate change mitigation investments that ai m to reduce harmful greenhouse gas emi ssi ons and slow down global warmi ng. Of this, 59% went to low- and middle-income economies. The remai ni ng $15 billion, or 24%, was i nvested in adaptation efforts to help countri es build resilience to the mounting impacts of climate change, i ncludi ng worsening droughts and more extreme weather events, such as extreme flooding and rising sea levels.

93% of this finance was directed at low- and middle-income economies.

HIGHER PRECEDENCE FOR SOLAR PV TO ACT AS CATALYST IN NEW ZEALAND’S CARBON MITIGATION PLAN TOWARDS ACHIEVING CARBON NEUTRALITY BY 2050 The New Zealand government announced solar installations across six of i ts i nstitutional campuses, utilizing the NZ$200m clean-powered public service fund. The ventures are to be introduced across selected universities, government and defense buildings, significantly di mi ni shing their carbon footprint. This acts as a predicted step to the broader obj ectives of accomplishing the 2050 net zero carbon emissions target, says GlobalData, a leading data and analytics company. Declining cost of solar modules, enhanced installation processes and economic incentives i ndi cate the distributed generation proj ects to take a serious leap over the large scale proj ects. With the residential segment taki ng up a considerable share of electricity consumption, the bulk of the proj ects planned to build a capacity of 6GW by 2050 is anticipated to be di stri buted not by grid but by roof-top, communi ty-based installati ons, etc.

SUNGROW DEBUTS THE 1500V LFP LITHIUM-ION ESS SOLUTIONS FOR A VARIETY OF INSTALLATIONS Sungrow, the global leadi ng i nverter soluti on suppli er for renewables, i ndi cates a robust growth momentum toward sustai nable development by showcasi ng flagshi p PV and energy storage i nnovati ons at SNEC 2020.

Can you please brief us a little more about the IIOT Technology?

The Theoretical definition of IIOT Technology is, it is a system of interrelated computing devices, mechanical and digital machines, that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. IIOT stands for "Industrial Internet Of Things". An IoT ecosystem consists of web-enabled devices that use embedded systems, such as processors, sensors, and communication sensors, to collect, send, and act on data they acquire from a specific Place. IIoT devices share the data they collect by connecting to an IoT gateway where data is sent to the cloud server. The devices perform most of the work without human intervention, although sometimes people can interact with the IIOT devices to set them up, give them instructions, or access the data. A simple example of IIOT Technology can be a Mobile App. In a Solar Plant, all the Inverters or breakers can be Controlled with just a click of a button in your Mobile Phone from any corner of the World.

WHAT ARE THE INITIATIVES TAKEN BY BULL POWER TO SUPPORT THE 'VOCAL FOR LOCAL' IN INDIA?

Hon’ ble Prime Minister Narendra Modi has made an appeal in the context of supporting Indian economy at the grassroots level with steps towards selfreliance. He has appealed for buying local product and supporting local business, because during the lockdown the, products and services by local vendors has helped us survive.

We always focus to make use of products made by local entrepreneurs and Indian Companies. This not only helps them sustain their livelihoods but also create jobs for people. We purchase goods from many such local producers, and these local really coming to our rescue with essential of good quality and timely delivery.

Headed for Gloss “Vocal for Local” Bull Power, endeavour to provide best solutions to our esteemed clients, we have partnered with Kirloskar Brothers Limited, established in 1888 and incorporated in 1920, Kirloskar Brothers Limited (KBL) is the flagship company of the $ 2. 1 billion Kirloskar group. and Jakson Engineers Ltd, founded in 1947, a diversified group with multiple business interests in Power Solutions with more than 2600 Cr. of group turnover including turnover of 1200 Cr from Solar business HOW HAS THE JOURNEY OF BULL POWER 'S BEEN SO FAR? HOW DO YOU SEE IT EVOLVING POST-COVID?

Bull Power was previously organised by Bull Fighter Consultancy, the firm organized seminars and workshops for farmers, Millers and traders, time to time on the better business of agricultural commodities. At the same time when the net metering policy came in 2015, the company shifted its focus in this direction and keeping this in mind in 2017, Mr. Acharya founded Bull Power Energy Pvt.

| AUGUST ISSUE 2020

The company' s goal is to maximize benefits to customers maintaining the quality work with good solar products. And with this mission, the company appointed Mr. Dinesh Kumar Bishnoi, who has been working in the field of renewable energy for last 15 years, as its managing director.

When we began working on rooftop and solar water pumping system the market was dominated by giant solar players, with such competition it was difficult to attract a big business. What started as a small off grid system, today Bull Power is ready to set up a large solar park in Rajasthan. The company has established its identity in Bikaner and in state of Rajasthan.

Simultaneously as we worked on a solar rooftop, we witnessed, no solar EPC company focused on households which could not afford solar, with a pre-set format of solar structure. Bull Power made it its USP and took the challenge of installing solar plants at all such households where major solar players refused to set up plants.

We immediately started looking for good fabricators for this, eventually our search was successful and we found the right fabricators who were passionate for Solar. In the meantime, few solar plants that we had in the beginning, the working conditions was a real challenge, but we overcame the rough patch and successfully executed the project and outcome that we witnessed from those plants convinced that we have overcome the obstacles.

In Bikaner district, we installed solar plants in more than 250 homes where solar installation was a challenge in itself, if Bull Power wouldn’ t have taken this project with its team having extraordinary skills and innovation, then our goal would have not been possible. The company constantly steps forwards with the excellent after sales service.

In order to grow further, the company appointed Mr. Mahesh Kumar Pareek, Senior Manager, ICICI Group, Mr. Sunil Joshi, Rajasthan In-charge of Square Yard Group and Mr, Manish Kumar Vyas, Senior Manager Angel Broking, as Director as the company' s vision.

In 4 years, Bull power has successfully installed many solar plants for huge industries including Carpet & Woollen Industry, Bhujia & Papad Udyog, Textile Mills, Peanut and mustered oil processing units, Cartoon Industry, RO Plant, Schools, Hospitals and Jewellery Showrooms etc.

During the COVID19 pandemic we noticed that the people who returned from the cities to the villages were very keen on the solar pump as agricultural products witnessed tremendous increase in demand, hence we reached out to such people through digital and social media. Bull Power benefited greatly with the Kirloskar Brothers and we reached out to those farmers.

We believe that agriculture has a huge contribution in the development of India and parallelly Bull Power set up excellent solar water plant projects to encourage farmers and their development. Solar water pumps were provided at affordable rates in more than 100 villages of about 5 tehsils near Bikaner district, and information was also provided about the benefits of using it, which led to the development of improved varieties of crops and good irrigation by our company.

AS WE HAVE SEEN THE ON SET OF DIGITAL ERA IN THE COVID TIMES, HOW DO YOU THINK THE TECHNOLOGY IS GOING TO EVOLVE?

Like other companies, Solar is affected by the challenges caused by the COVID-19 pandemic. However, Solar has an agile business model and is fundamentally a digital business, which means that we are well positioned for the next normal.

To stay one step ahead we focused on digitalization, and today solar business need this transformation. Being an innovative company Bull Power always works on new working concept. We want to serve our clients in better, so our investments in front-line digital businesses combine our deep industry knowledge and decades of digitalisation experience with their business innovation and new, scalable digital platforms. This means that we are able to deliver innovative industry solutions to the market at a higher pace.

We are strategically striving to improve ourselves for better growth in industry transformation and digitization. We work constantly towards making Solar Energy an attractive business model for innovative and valuable users.

INSIGHTS Any other industrial/commercial establishments currently using steam/hot water for process applications can also employ CST with a minimum tinkering to the existing setup. For industrial processes where lower temperature range less than 120°C is required, technologies such as the Scheffler dish and Compound Parabolic Concentrator or Non-imaging Concentrators are common and for higher temperature range applications, technologies such as Parabolic Trough, Linear Fresnel and Paraboloid dish with tracking are preferred.

Financial Supports to promote CST

The Ministry of New and Renewable Energy is implementing a programme on concentrated solar thermal aimed at peak shaving, conservation of electricity and fossil fuels and providing a clean, nonpolluting solution to meet the process heat requirement in community, commercial and industrial sectors. Various promotional incentives in the form of Central Finance Assistance (CFA) are available for concentrating solar thermal projects under the Jawaharlal Nehru National Solar Mission. This programme is implemented through multiple agencies for scaling up of CST projects. These agencies include SNAs, IREDA, SECI, Channel Partners, and other government agencies like PSUs, Institutions, NHB, NABARD etc. Ministry also has empaneled Channel Partners, Manufacturer/suppliers and Entrepreneurs for CST technology.

UNIDO project on CST

USING CONCENTRATING SOLAR THERMAL TECHNOLOGIES FOR INDUSTRIAL PROCESS HEAT APPLICATION IN INDIA India is endowed with a vast solar energy potential. About 5, 000 trillion kWh per year of solar energy is incident over India’ s land area, with nearly all of India receiving an average sunshine hour of 5-7 kWh/m 2 /day. The abundant solar radiation, clean character of solar energy, high cost of fossil fuels and negative emission consequences, along with large requirements for process heat below 250°C are the key drivers of the strong focus on the development of solar thermal applications in India.

UNIDO has identified a total market potential of 12. 5 GW for industrial applications, including low temperature applications, in India during preparation of CST Roadmap 2022. The Concentrating Solar Thermal (CST) technologies, due to efforts of the indigenous technology providers, are making technical and economic sense today in many applications such as steam cooking, wastewater treatment, laundry services, dairy thermal applications and the automotive Sector. The heat requirement is met by burning conventional fuels such as coal, furnace oil, natural gas and electricity. Use of solar concentrator technology integrated with system process heat demand can help replace/ reduce conventional fuels which in turn will help reduce GHG emissions.

Concentrating Solar Thermal Technology

CSTs are very well suited for industrial process heat applications in the medium or medium-high temperature ranges. They can be used effectively to supply energy in the form of heat, and therefore huge potential exists for the use of concentrated solar energy in the industrial sectors. Industrial heat is characterized by a wide diversity with respect to temperature levels, pressures and production processes to meet the many different industrial process demands. CST technologies track the sun’ s incoming radiation with mirror fields, which concentrate the energy towards absorbers, which then transfer it thermally to the working medium. The heated fluid or steam may reach high temperatures and may be used for various processes requiring heat. CST technologies can produce a range of temperatures, between 60°C and up to over 350°C, which can be used in a variety of industrial and commercial heat applications. The industries showing good potential for implementation of solar concentrators are food processing, dairy, paper and pulp, chemicals, textiles, fertilizer, breweries, electroplating, pharmaceutical, rubber, desalination and tobacco sectors.

The GEF-UNIDO project on “Promoting Business Model for increasing penetration and scaling up of solar energy” was designed to complement Ministry (MNRE) support programme by helping to remove barriers associated with Concentrating Solar Thermal (CST) technologies, its awareness, capacity building, market and financial barriers. The implementing partners of the CST project is the Ministry of New and Renewable Energy (MNRE), Indian Renewable Energy Development Agency (IREDA), and National Institute of Solar Energy (NISE). The project was conceived with an aim to contribute to the GEF Climate Change Strategic Objective namely, promoting investment in Renewable Energy (RE) technologies by transforming the market for solar energy for industrial heat applications in India through investment, market demonstration, development of appropriate financial instruments, development of technical specifications, capacity building and contributions to establish a favorable policy and regulatory environment.

Soft Loan Scheme under UNIDO-IREDA supported MNRE project UNIDO has partnered with IREDA (Indian Renewable Energy Development Agency) to develop and implement an innovative finance/loan scheme to further promote the deployment of CST projects in India for heating and cooling applications in potential industries to reduce energy consumption and Greenhouse Gas (GHG) emissions. The highlights of the currently available financial incentives are as follows.

The beneficiary’ s or project developer’ s contribution would be 25%.

The financial incentives provided for CST installation include CFA (Central Financial Assistance) from MNRE and accelerated depreciation benefit.

Additional support is available from UNIDO project in terms of technical feasibility and soft loan from IREDA. Bridge loan against subsidy and at normal interest rate would be available.

Support is available also for improving the manufacturing of CST system/components.

Loan for the CST project would be provided at an interest subvention of 5% from the current rates using funds under the project. Both the loan and MNRE subsidy would be bundled in form a financial package by IREDA. The project is designed to complement MNRE’ s support programme by helping to remove barriers associated with Concentrating Solar technology, its awareness, capacity building, market and financial.

ROOFTOP SOLAR GOES DIGITAL !

Despite 5. 5 GW and counting, Rooftop Solar (RTS) still lags in realization of its true potential. Policy & regulations, financing and process streamlining issues continue to impact its accelerated deployment and some of these pitfalls have been accentuated by the ongoing COVID-19 pandemic. RTS projects implementation is expected to have a short gestation period.

However, given the pandemic situation, delays are inevitable.

Thus, there lies a great opportunity to streamline and expedite RTS operations and implementation process. Digitization of RTS will significantly reduce these delays and improve overall performance.

Digitisation – requirement and utility

Digitisation plays a vital role in every sphere of the RTS ecosystem, be it feasibility assessments, vendor and consumer on-boarding, DISCOM approvals, monitoring or financing. For instance, lack of data regarding the total capacity of RTS plants interconnected to a distribution transformer (DT) and the limits imposed by state net metering (NEM) regulations on NEM connections based on DT capacity, lead to data asymmetry and process inefficiencies. Online DT mapping for the entire DISCOM coverage area will assist DISCOMs to efficiently manage the distribution network and provide timely approvals. Secondly, for successful RTS tenders, if a potential pipeline is offered upfront through an online data room, true and competitive price discovery is undeniable. Thirdly, Unified Web Portal (UWP) enables DISCOMs to provide a seamless experience for consumers to apply for grid interconnection, to manage vendor activities and to claim subsidy, all on a single window digital platform. Fourthly, post vendors’ empanelment, the consumer on-boarding process can be digitised by floating online expressions of interests (EoI), thereby reducing the transaction costs and fostering RTS deployment.

Finally, online performance monitoring of RTS projects will empower key stakeholders with competitive performance benchmarking, access to components’ performance ratings, overall visibility of the RTS plants’ performance including target environmental parameters, demand forecasting, planning and scheduling, RPO compliance, provision of generation-based incentives, participation in peer-to-peer energy markets (block chain enabled), certified and validated generation data -

facilitating bankers in project yield assessment, reliable O&M information, performance rating for developers etc. For financiers, the entire loan process involving application, verification, approval, monitoring and closure can also be automated through online document submission systems, chatbots, digitised tracking systems by combining with the online performance monitoring.

Current efforts on RTS digitisation

Several market players and DISCOMs have already implemented many of the above leading digital initiatives viz. , launch of UWPs & online consumer aggregation, online monitoring, online DT mapping (e. g Telangana DISCOM), online loan processing by Banks (e. g IDBI) etc. SUPRABHA, the World Bank-SBI rooftop solar technical assistance program has already made a comprehensive digital impression in more than 10 states in developing UWPs. It has also established more than 12 online data rooms covering more than 4000 sites with 350 MW capacity across 12 States.

Such data rooms have been a key contributor to the price discovery for tenders over 200 MW. SUPRABHA is currently working on a Vendor Management Portal to assist DISCOMs to manage the post-bid processes.

SUPRABHA recently supported National Institute of Solar Energy (NISE) in establishing a remotely monitored RTS platform and has also initiated work on online site monitoring mechanism and an automated loan process mechanism for banks. Post COVID-19, SUPRABHA believes that RTS digitisation is the way forward to intensify the momentum towards achieving the desired targets.

HAS THE OF VIRTUAL SOLAR POWER PLANTS ARRIVED? AYUSH MAHAJAN Co-founder & CTO, PV

The Indian power sector has been undergoing transformation since the past few years, with growing contribution of renewable resources in the energy mix.

The limited supply of fossil fuel has encouraged the penetration of distributed energy resources (DER) in the Indian power sector. Grid integration of DERs has allowed the shift from centralized to decentralized systems. The development of this newly designed flexible energy network can be achieved using virtual power plants (VPP).

VPP allows numerous decentralized power plants to aggregate and operate as a single platform. It functions as a Cloud-based or SaaS-based platform which governs multiple decentralized power plants through various distribution routes and demand centers.

Distributed plants can be remotely operated and controlled through VPP. Various functionalities of VPP like distributed asset monitoring, asset analytics, distributed asset control, renewable energy management, energy storage management, EV charging asset management, and demand response management are anticipated to influence the adoption of VPP in the Indian power sector. | AUGUST ISSUE 2020

Diagnostics

In the last 5 years, renewable energy generation has increased to 1516 TWh and 98. 37 TWh worldwide and in India, respectively.

These incremental generation rates demand better storage solutions for reliable and secure penetration of renewable generators. These are also the most cost-competitive solutions compared to conventional sources. We are aware that these renewable generators and storage solutions are a part of the bigger picture “Decarbonization and reduction in Nonconventional energy sources dependence� along with electric vehicle adoption which has become a real thing now.

The modular and stochastic nature of these non-conventional sources poses a big challenge for the grid. After a significant penetration, these stochastic nature can destabilize the grid and make it less reliable, limiting the contribution. This is where the Virtual Power Plant (VPP) comes into play.

Conceptually, VPP aggregates different DERs and demands a response to act as one power plant withcharacteristics similar to the conventional power plant. The various participants in VPP are PV plants (residential and large scale), wind farms, electric vehicles, biogas CHP, hydropower plants, hydrogen storage, demand-side response, etc. VPP brings together operating

curves of different DERs and aggregates the characteristics to generate one single operating profile which is reflected in the load dispatch center or the electricity market with more reliability, robustness, and predictability. Few benefits of VPP are:

DR. AKANKSHA TYAGI Research Analyst, Council on Energy,

Optimized utilization of available resources and improved efficiency and reliability of the overall system Better revenue opportunities Ancillary services from aggregated DERs and stacking of different revenue line Improved scheduling of renewable generators

There are a few challenges that need to be addressed before the implementation of VPP. One of the biggest challenges are different geographical locations of DERs and therefore different power inj ection points in the grid. To solve this, various network constraints and real-time network conditions have to be met.

Additionally, relevant commercial and technical regulatory policies need to be in place for large-scale adoption of VPP. Current Advancements in VPP solutions North America, China, Australia, and Europe are the leaders in the deployment of “VPP as a solution”.

Europe: Hosts leading VPP proj ects like FENIX, REstable, Regenerative Combined Power Plant proj ect, SolVer proj ect, etc. with focus on DER aggregation for providing various ancillary services.

China: Claims to have the biggest operational VPP (owned

by State Grid Jiangsu Electric Power Co. ) and target to contain integrated controllable loads with a power of around 10 GW for 2020.

Australia: Focusing on the residential sector and aiming to save costs for end consumers.

North America: Focusing on energy management in the industrial and commercial sectors leading to cost-effective operation of integrated assets.

There are various existing policies and regulation in India indirectly supporting the VPP adoptionIntroduction of 5minute scheduling, metering, accounting, and settlement in the Indian ElectricityMarket.

Regulation by APERC on “Forecasting, Scheduling and Deviation Settlement of Solar and Wind Generation Regulation”, Andhra Pradesh, 2017.

Net metering policy of Uttar Pradesh RTC tenders and KUSUM scheme which involves 0. 5 MW to 2 MW solar power plant installations across sub-stations in the country.

These calculated and ambitious targets show that the era of VPP has arrived and we will be witnessing many such changes in the future.

There are a few challenges that need to be addressed before the implementation of VPP. One of the biggest challenges are different geographical locations of DERs and therefore different power injection points in the grid. To solve this, various network constraints and realtime network conditions have to be met.

With the rapid expansion of distributed renewable energy (DRE) sources, virtual power plants (VPPs) would play a critical role in future electricity systems. These systems refer to an aggregated network of DRE sources – like rooftop solar PV systems – coupled with energy storage systems, which interact with grid operators in real time. By aggregating such small DRE capacities, these systems act as a single operating unit within the grid, similar to a conventional power plant. A central control unit monitors and manages the power generated by these distributed generators to meet the consumer demand and assist the grid operations. While the concept is still at a nascent stage in India, countries like Australia and the US have several VPP proj ects at different stages of completion. Tesla is empowering about 50, 000 houses in South Australia with rooftop solar systems and Tesla batteries. The total aggregated capacity under this programme would be 250 MW of solar and 650 MWh of storage.

VPPs are gaining traction as they offer multiple benefits to the consumers and grid operators. Some of the main benefits for the consumers include access to reliable and clean energy supply, additional savings from increased self-consumption of solar electricity, and earnings from the export of stored power to the grid. Another critical benefit arises from the ability of these systems to disconnect from the primary electricity grid and operate in an islanding mode. Such autonomy ensures continuous power supply to the consumers, even in the events of grid failure.

These virtual plants would assist the grid operations and power distribution companies (discoms) as well. Firstly, by aggregating the distributed generation, the discoms would have access to flexible and reliable power, at times comparable to a conventional power plant. This would allow discoms to reduce generation capacity and power procurement under the long-term power purchase agreements. Secondly, by redirecting the available solar electricity, they can manage demand and achieve load levelling.

Finally, as these systems can relieve the network load, discoms can defer the augmentation of the existing network and construction of new elements. Overall, these services translate to reduced expenses for discoms with improved operational efficiency. The Council on Energy, Environment and Water (CEEW) recently conducted an economic feasibility study of solar-storage microgrids with BSES Yamuna Power Limited (BYPL), a Delhibased discom. Our research indicates that optimising the battery dispatch to improve availability during the discom peak hours can result in a significant profit of about INR 1. 08 for each unit of solar electricity generated by the PV system in the microgrid. BYPL benefits the most by reducing the procurement of expensive power from conventional power plants by ~54 per cent.

However, interventions would be required to address regulatory and fiscal barriers to facilitate the scale-up of VPPs. Some of the central regulatory responses needed are favourable market designs to support the participation of VPPs in electricity trading, an ancillary market, and differential tariffs for all consumer categories. The sector also needs incentive mechanisms to promote electricity export to the grid, and innovative business models to share the financial burden and benefits equitably. Such focused actions would drive the uptake of these systems and revolutionise the Indian power sector.

With an ambitious renewable energy (RE) target, increasing customer awareness and pro-RE policies, the Indian power sector has seen substantial change in its energy mix. Albeit challenges, we are seeing a steady shift of our power supply from centralised conventional sources to more decentralised renewable energy sources like rooftop solar power plants.

While the shift is substantial, there is a lot more to be done to reach our ambitious RE target of 175 GW by 2022. Creating a robust power infrastructure is one of the many measures which will enable India to promote renewable energy amongst developers and the consumers alike. Virtual Power Plant (VPP) is an innovative way as well an important aspect in the creation of such an infrastructure.

Moreover, increasingly visible impacts of global warming, the falling costs of renewable power plants and the pro-consumer net meter policies have encouraged the adoption of decentralised power systems popularly known as distributed energy resources (DER). A Virtual Solar Power Plant (VSPP) is a network of such decentralized, medium-scale solar power generating units as well as flexible power consumers and storage systems. These interconnected units are dispatched through the central control room of the Virtual Power Plant but nonetheless remain independent in their operation and ownership. Thus, it relieves the load on the grid by smartly distributing the power generated by the individual units during periods of peak load. VSPPs can also support trading of power on exchanges. In short, VSPP is a software as a service (SaaS) based platform which connects multiple decentralized power plants.

Apart from the DERs, the DISCOMs, the TRANSCOMs, the power exchanges, the technical virtual power plant (TVPP), the commercial virtual power plant (CVPP), the aggregators comprise the Virtual Power Plant ecosystem. While the functions of most of the other parties are well known, TVPP, CVPP and aggregators are parties more specific to a VPP. A TVPP operates more at the Distribution and Transmission levels while the CVPP operates at the DER levels and the aggregators bring together the TVPPs, the CVPPs and the DERs. These participants of the Virtual Power Plant (VPP) are connected to the VPP’ s central control system via a remote-control unit. This central control system uses a special algorithm to adjust to balancing reserve commands from transmission system operators, j ust as larger conventional power plants do.

VPPs perform various critical functions including renewable energy management, asset analytics, DER management and control, demand response management and energy storage management. These functionalities would help create the infrastructure required for new government policies and plans such as the National Electric Mobility Mission Plan by enabling effective management of EV charging stations. All said, what India needs is a strong regulatory framework and work on addressing the security and privacy issues to support the implementation of VPPs on a large scale.

Considering the current situation, the demands of the changing power mix and future power goals, the era of Virtual Solar Power Plants has clearly arrived and we have to create a conducive and secure ecosystem for VSPPs to grow and thrive.

UNLEASHING

A SOLAR ROOFTOP REVOLUTION IN INDIA

India is pursuing an ambitious program for development of 175, 000 MW of renewable energy by 2022 comprising 40, 000 MW from rooftop solar panels. While about 50% of the overall target of 175, 000 MW is achieved by the end of 2019, performance of the rooftop segment is less than 10%. All the states and union territories in India had issued net-metering policies between 2013 and 2016. Theoretically every electricity consumer can be a “prosumer” – producer and consumer of electricity! Now, with the prices of the kilo-watt (kW) scale solar photovoltaic (PV) systems in the range of INR 50, 000/kW (or US$ 700/kW) including installation charges, and many DISCOMs actively promoting rooftop PV, the time has come to unleash a solar rooftop revolution in the country. In most part of India 1kW panel could generate average 1200-1500 kWh or more of electricity in a year and at this price levels, the payback period for rooftop solar is about 4-5 years for commercial customers and 6-7 years for residential customers while the life of a PV system is 20-25 years with minimum annual maintenance and performance deterioration.

The DISCOMs have been apprehensive of their revenue loss from rooftop solar as those installing such systems are high volume customers who pay much higher rate than the average power purchase cost for the DISCOM; and for buying the electricity from rooftop PV, DISCOMs have to regulated tariffs which are again higher than their average power purchase cost. Hence, DISCOMs have been viewing rooftop solar as a double-edged sword which has been the main hurdle in scaling up rooftop solar. It is time to have a relook at the new market dynamics to see how rooftop solar can help DISCOMs. Advantages to DISCOMs from Solar Rooftop Systems

In most urban areas the feeders are mixed use with commercial and residential customers and the electricity generated during the day by rooftop PV gets consumed in the same locality in the low voltage network itself. On such feeders, the peak demand is usually during the day while solar rooftop systems generate power. Typically every year as the load increases in each locality, DISCOMs need to upgrade their distribution infrastructure to meet the increased demand. This exercise DISCOMs do periodically. In certain cases, they need to build bigger substations and the transmission companies have to build high voltage lines to supply to the new substation. In urban India, space for locating new transformers and substations is not easily available. If the peak oad is partially met by local generation from rooftop PV, the distribution system upgrade can be delayed for years.

A recent study by Council on Energy, Environment and Water and BSES Rajdhani Power Ltd in Delhi have calculated a net benefit of INR 0. 22 per kWh generated from rooftop solar 1 . They considered following benefits: Avoided power purchase cost - fixed cost paid to generators for the power contracted through long term power purchase agreements Avoided transmission charges - fixed transmission charges paid to transmission companies based on the quantity of power contracted Avoided distribution capacity cost - capex avoided in enhancing the distribution network capacity to meet the additional load Avoided cost of renewable energy certificates to meet the renewable energy purchase obligation (RPO).

Avoided working capital cost for the 4 items listed above

Several successful pilot projects have come up in different countries that have established the technology. The participants in P2P marketplaces could sell electricity from their rooftop PV to other participants at the best prices they can get almost in real-time; as well as participants with no rooftop PV could buy “green” electricity at the cheapest rate on the blockchain platform and schedule their consumption or even meet their RPO targets. ISGF along with our technology partner Power Ledger, Australia is implementing a blockchain pilot project in Lucknow City for P2P trading of power from rooftop solar which is expected to be live in September 2020.

Steps to Scale Up of Solar Rooftop Systems

The primary obstacle in offtake of rooftop systems is the lack of awareness amongst the customers. They do not know what systems to buy, how to get it installed and how to get the net metering connections. Our recommendations are: Commoditized solar rooftop systems: We guess the market is ripe to launch commoditized rooftop PV systems that can be bought from local appliances stores. Government(s) shouldactively promote this.

DISCOMs could empanel tested systems that may be made available in local appliance stores.

Testing and Certifications for Installers: DISCOMs and other designated agencies may conduct training programs and certify skilled installers. This could generate millions of new jobs across the country.

Government subsidies to DISCOMs: Rooftop PV systems are economically attractive to customers and they do not require any grant or subsidies. Government’ s support should go to DISCOMs who need to upgrade their distribution systems to accommodate increasing share of distributed renewable resources. ISGF modelling studies in 2019 estimated about 10 GWh of battery energy storage systems to integrate the targeted 40 GW solar power with medium voltage and low voltage grid.

Promote P2P Trading: Frame appropriate regulations to promote P2P trading of rooftop solar power amongst customers; and the electricity produced and traded may be counted in the RPO target of the DISCOMs. In 2016, Government of Haryana issued an order mandating all new buildings in the state on a plot size of 500 Sq Yard or above to have solar rooftop of minimum 1 kW or 5% of the connected load. We propose to make this mandatory all over the country and the cost of rooftop solar systems may be included in the total cost of the house for home loans by financial institutions.

Both rooftop solar and electric vehicles (EV) are typically connected to the low voltage grid. The AC charging points for EVs in new buildings may be equipped with vehicle–to–grid (V2G) functionalities. This would help store the solar generation in the EV batteries when local consumption is less than solar generation avoiding curtailment. The EV batteries could also help smoothen the intermittency of solar generation from the rooftop systems thereby improving the power quality in the low voltage grid. Various incentives schemes may be framed for the EV owners who participate in the V2G program. Many of them could buy electricity from the grid when price is low and sell back to the grid at higher prices during peak hours.

Time has come to unleash a solar rooftop revolution in India!

On the cost side, the study considered revenue loss, program administration cost and added distribution services cost to the DISCOMs. BRPL is actively promoting rooftop solar in their service and have installed 59 MW till end of 2019. This study should be an eye opener for other DISCOMs discouraging rooftop solar.

FOCUS LCOE: WILL CURRENT ECONOMIC DOWNTURN SPEED DECLINE IN SOLAR POWER COSTS? According to a report from Wood Mackenzie, the cost of solar power is dropping faster than expected as the coronavirus stifles demand. Rooftop-scale prices will fall 17% over the next five years, that’s steeper than the 14% it had expected before the coronavirus. Prices for commercial systems sliding 16%, and utility-scale installations will decline 20%, compared with the prior forecast of 13% and 16%, respectively, as per the report. Also with the demand destruction caused by Covid-19, the risk of oversupply is increased, and module suppliers have reduced prices.

Already, solar power is among the world’s cheapest electrical sources, falling system costs are boosting the competitiveness of solar against coal and natural gas.

MANOJ GUPTA VP-Solar and Waste to Energy Business, Fortum India Pvt Ltd

There has been immense growth in solar power capacity during the last decade. Solar has now become the fastest-growing source of renewable energy in the world. Formerly, the swift installations were mainly due to policy support and a sharp reduction in technological cost heads and growing environmental concerns. However, with the economic decline induced by the outbreak of the ongoing pandemic, demand from various segments has seen a downturn due to the financial uncertainties faced by the customers. Commercial and industrial installations are likely to be negatively affected as discretionary spending will be deferred and maintaining short-term cash flow will assume primacy. Also, supply chain disruptions and declining investments has led to a delay in proj ect commissioning for the utility segment. However, all this impact may be seen during this year only and we may again see the fast pace development in the renewable sector from next year onwards along with the growth of the economy.

The COVID-19 had significantly affected the energy sector value chain. The international price for oil and gas has come down to a record low which we have seen in early 1995. The electricity demand has also come down by 20 to 30% due to reduced economic activities during this pandemic period. As the solar PPAs are fixed priced long term PPAs, this has led to an increased share of the renewables in the grid. The reduced electricity demand and increasing share of renewables in the grid has led to a threat to the electricity companies to maintain the grid stability.

The indo-chinese geopolitical face off has also led to the trade restrictions and the new capacity additions of solar proj ects have come down significantly. India imports almost 80% of its solar equipment from China and the trade war and imposition of safeguard duties and custom duties uncertainties has led to a halt in the new capacity additions in the nearterm. Now the challenge is to integrate the solar and wind with reduced electricity demand scenario. Though situations are getting normal and our energy requirement has reached t par with the daily energy requirement of the corresponding previous year (around 3700 Million Units per day).

The Covid 19 will impact the solar LCOE in the short term, until things become new normal. The LCOE in solar is a function of proj ect cost as well as the interest on debt. Though the overall proj ect may get increased due to the Covid 19, but it will be nullified by the reduced interest on debt. Recently RBI has reduced the repo rate and the interest on debt may come down and will nullify the impact. The recent SECI solar tariff discovered has seen the new low in the solar tariffs to the tune of INR 2. 36/kWh, is a signal that the market has considered the Covid 19 as a short term event and now things are getting normal. Comparing the Indian tariff trends with global tariff trends we still believe that there is a significant headroom for further reduction in Indian solar tariffs.

For example The tariff discovered in a recent UAE solar proj ect was US Cents 1. 69/ KWh Which is about 30% lower than the Indian solar tariffs.

There are uncertainties regarding the safeguard duties on solar components imported from China and other countries which forces developers to keep a buffer to absorb these uncertainties. There are also urgent uncertainties to the developers in terms of renegotiating the tariffs by the taker. We have seen the examples in Guj arat and Andhra Pradesh where state governments initiated renegotiation of solar tariffs with the developers. These uncertainties are accounted for by the developers while quoting in the bids and we still get a higher price as compared to the global international price of solar tariff. The technological developments and reduced interest rates will still be the key factors to bring the solar tariffs down in the Indian market.

I was privileged to start my career in 2010, during when the investment in generation through solar technologies was considered solely an opportunity to diversify. During that time, the maj ority of financiers and investors considered most of the renewable technologies to be unproven and too risky. I was also fortunate to be present in the NVVN’ s auction meeting where 150 MW of solar PV proj ects and 500 MW of solar concentrated power proj ects were won by IPPs through a reverse bidding route. 30 individual proj ects of 5 MW each were successfully offered to various IPPs where original feed in tariff was INR 17. 91 per kilowatt hour (kWh), but were offered to the bidders with an auctioning route, where lowest winning bid came out to be INR 10. 95 per kilowatt hour (kWh) and highest winning bid as INR 12. 76 per kilowatt hour (kWh). At that time, experienced power sector and industry experts were questioning the future of solar, challenges it would be posing to the grid and transmission infrastructure utilization with mere CUF of 15 to 20%. I still remember during one my client meeting, one of the consultants retired from thermal plant domain and was consulting that firm mentioned that solar is not a rocket science to install and would be like (Lego) building block toy which the power industry has started to play with. And talking about today, even with Covid-19 and the market downturn didn’ t hinder the solar scenario, the solar PV tariffs have reached a record low of INR 2. 36 per kilowatt hour (kWh). With technology advances, policy push by government, awareness about the environment and most importantly the economics is making more and more companies diversify their assets with green energy portfolios.

At the end, it is the commercial viability of the solar industry which is deriving the path towards sustainable, affordable and clean power. As per Bloomberg (BNEF), the view on India’ s energy transition and green energy revolution mentions that India is the one of the largest renewable energy auction markets, having ambitious renewable energy targets and multi-billion dollar investment opportunities. With ongoing auctions being successful even at this pandemic time and Government of India is coming up with innovative models like peaking power requirements, hybrids systems and round the clock power through renewables are providing assurances to investors and market forces. Electricity through solar power these days are cheaper, cleaner and more sustainable than conventional generating units. The (lego) building block toys have matured now and are giving tough competition to the conventional power sector. With the growing economy and power consumption cost through solar is going down, it is making good commercial sense to the investors. With large solar parks already seeing tariff plunged enough, the average levelized cost of energy (LCOE) generated is expected to fall further. Enabling factors like the ongoing reforms mentioned in draft electricity amendments, extension in the waiver of interstate transmission charges and industrial growth expected to bounce back solar power would be fighting its place.

POLICY TALK

IS ULTRA-MEGA RENEWABLE ENERGY POWER PARKS (UMREPPS) A NEXT WAVE OF GROWTH IN RE?

The Ministry of New & Renewable Energy (MNRE) has recently announced Modi fi cati ons i n Scheme for Development of Solar Parks and Ultra Mega Solar Power Proj ects. So far, there are seven modes under which the scheme i s i mplemented. The Mi ni stry has now i ntroduced another Mode-8 named ‘ Ultra Mega Renewable Energy Power Parks’ (UMREPP).

The power proj ects inside the UMREPPs may be developed either under developer mode vi a tari ff-based competi ti ve bi ddi ng (TBCB) process or under EPC mode or any combination of both. The SPPD or any of its individual promoters cannot take part i n a tari ff based competi ti ve bi ddi ng process.

Solar Power Park Developer (SPPD) under UMREPP includes CPSU/ State PSU/ State Government organi zati on or thei r subsi di ari es. A j oi nt venture company (JVC) between two or more of the above entities may also act as the SPPD. There has been a renewed interest in setting up Ultra Mega Renewable Energy Power Parks (UMREPPs) wi th SECI, NTPC and other state governments making announcements to come up with huge capacity. The process is advanci ng to achi eve the 450 GW renewable energy target set for 2030 by the government.

MANOJ GUPTA VP-Solar and Waste to Energy Business Fortum India Pvt Ltd

We believe that the recent modifications to the pre-existing guidelines for ‘ Development of Solar Parks and Ultra Mega Solar Power Projects’ will help the country move towards achieving its long-term goal of 450 GW by 2030. The proposed scheme envisions to support States/Union Territories in setting up solar parks at various locations in the country, with the vision of creating the required infrastructure to set up solar power projects. The scheme recommends setting up at least 25 solar parks and ultra-mega solar power projects across various locations. The recent modification in the policy is now beneficial to the state also as they are also getting beneficial by having a share of the tariff. We currently

| AUGUST ISSUE 2020

operate power plants in two of those locations, i. e. Bhadla in Rajasthan and Pavagada in Karnataka, both of which are considered to have huge potential for energy generation and our experience of construction and operation in these solar parks are great. This scheme will be instrumental in driving economies of scale in these states and attract foreign capital to support existing power plants. These solar parks will, in return, provide suitable developed land with all allowances, transmission systems, water access, road connectivity, and communication network which will help in the growth of the sector. This will accelerate and the installation of grid-connected solar power proj ects for electricity generation on a large scale. Additionally, the government has ramped up its speed of taking various actions to enhance the development work in the renewable energy sector with various combinations like pure solar, wind-solar hybrid, solar hybrid, RTC power etc, this scheme will be a good support to achieve the commissioning on time otherwise the timely availability of land and Power Evacuation is the biggest hurdle in growth of this sector.

SUSHEEM PANDEY Head Solar, CEO Solar Park, VishWind Infrastructures

With the fall in conventional energy demand due to pandemic Covid19 and lockdowns, renewable sources (mainly wind and solar) saw their share in electricity substantially increase at record levels in many countries. In less than 10 weeks, the USA increased its renewable energy consumption by nearly 40% and India by 45% (see graph). Italy, Germany, and Spain set new records for variable renewable energy integration to the grid.

The Ministry of New Renewable Energy has been quick to respond to this radical shift in energy sources from fossil based RE. In order to give further boost to Solar Power and achieve its target of 40 GW through Parks MNRE introduced a new scheme for solar parks called Ultra Mega Renewable Energy Power park (UMREPP) in June 2020. The move came in order to provide a further boost to the development of the renewable energy sector especially solar, which is facing slowdown since the lockdown implementation due to coronavirus pandemic.

Under UMREPP Solar Power Park Developer (SPPD) will include CPSU/ State PSU/ State Government organization or their subsidiaries. Moreover, a j oint venture company (JVC) between two or more of the above entities may also act as the SPPD. The state government will provide necessary assistance to the SPPDs in identification & acquisition of land for setting up of UMREPPs and also to facilitate all required statutory clearances. The state government may designate any state government organization for the purpose. land for UMREPP to be allotted with a condition that the development must be completed within 2 years (with a provision of extension for 1 year under extreme cases) failing which

the state government may take back the allotted land in consultation with this Ministry. a committee will be set up under the Chairmanship of Principal Secretary/ Secretary (power/energy/renewable energy) to : 1. facilitate setting up of the UMREPP 2. Monitor the progress and 3. Fix the one-time upfront charges and annual Operation & Maintenance (O& M) charges etc. to be charged from the power developers.

For the above activities, the state government or any organization designated by the state government would be paid a facilitation charge of Rs 0. 05/unit of power being generated from the projects in the UMREPPs for the entire PPA period of the project. This facilitation charge may be paid to state governments only on the quantum of power that is exported outside the state from that UMREPP and only if no facilitation charge or similar charge is levied under the state government policy.

Compensation to the SPPD: The SPPD will be entitled to the compensation for the development and management of the UMREPPs under Central Financial Assistance (CFA).

Power Projects inside UMREPPs: The power projects inside the UMREPPs may be developed either under developer mode via tariffbased competitive bidding (TBCB) process or under EPC mode or any combination of both.

PRADEEP CHAUHAN Country Manager - India subcontinent, SolarPack

India has accomplished name for itself in development of Mega Solar Parks like REWA (750MW), Pavagada (2050MW), Bhadla (2245MW), Kurnool (1000MW), Kadapa (1000MW), Kamuthi (648MW) and many others, which are now fully operational.

Further there are approx. 25 to 30 more such medium and large-scale Solar Parks are underway development and construction. The present plan to develop 40GW capacity Solar Parks itself is humongous, however the pace at which these solar parks are being developed and offered to Developers for setting up units is definitely faster than the complete green field development yet quite sluggish as compared to the growth traj ectory which is needed to achieve the Y-O-Y installation leading to 100GW installed capacity by 2022, which definitely is going to be missed looking at present pandemic effect that has halted the projects and overall industry growth including auctions, award process, development and construction, adding more to the concerns are issues of crimped supply chain due to SGD and BCD barriers.

Ultra-Mega Renewable Energy Power Parks (UMREPP) Policy provide much need guidelines to states for the development of large-scale solar parks, which should assist states to quickly conduct study and acquire land for creation of infrastructure. The solar parks already developed and under development clearly demonstrate the fact that foreign investors and investment funds prefers solar parks with lower risk in the development side, in a way, we can say that 20% of the existing installed capacity has been contributed by these solar parks.

In December 2014, the Ministry of New and Renewable Energy (MNRE) launched the “Development of Solar Parks and Ultra-Mega Solar Power Projects” scheme. to develop at least 25 Solar Parks to install cumulative capacity of over 20 GW. In 2017, the target for the number of solar parks

| AUGUST ISSUE 2020

was increased from 25 to 50 and the corresponding capacity addition target was enhanced from 20 GW to 40 GW by the year 2022. Since then announcement of seven modifications (modes) were notified in the policy to incentivize the targeted capacity addition. During the last 6 years only about 8 GW MW capacity has become operational. In the backdrop of achieving a target of 175 GW of RE by 2022 and slippages in achieving targeted capacity addition in 2019-20 and current FY, in June 2020, another modification (mode 8) in the scheme namely ‘ Ultra Mega Renewable Energy Power Parks’ (UMREPP)’ has been notified.

In my opinion, States should follow the Public Private Partnership (PPP) Model for faster Development of Solar Parks to catch up with the plans of capacity addition.

Power Evacuation Infrastructure creation around these UMREPP is another challenge, where the progress is sluggish and certainly not allowing development as per the annual targets, needs to be ramped up drastically, many states have already started curtailing due to evacuation constraints in the absence of localized demand.

Green Energy Corridor (GEC) slow development due to issues of funding support is another area, if expedited, that should make a very significant impact in tandem with UPREPP’ s to accomplish the goals.

States Performance in development Solar Parks will be the key driver, which will fuel the next level of growth, this concept has already demonstrated the viability and results on lower discovered tariffs, faster developments due to land, transportations, transmission infrastructure availability. Indian PSU getting award of Solar Park Development assignments oversea in African Countries is an illustration of the concept potential.

PERSPECTIVE

THE 5 ‘IN’ TO BUILD SELF RELIANT SOLAR INDIA INTENT, INCLUSION, INVESTMENT, INFRASTRUCTURE & INNOVATION

Prime Minister Narendra Modi’s aggressive push for ‘Make in India’ to bolster domestic manufacturing and make its economy ‘selfreliant’ in the post-pandemic era is a welcome opportunity for India’s solar energy sector. Supply disruptions and subsequent shortage of solar components and modules have impacted India’s ambitious energy target of achieving 100 GW of solar capacity by 2022.

There is an urgent need therefore, for India to devise a policy framework aimed at creating a diversified domestic manufacturing industry for solar modules as well as ancillary products, significant government reinvestment in public sector undertakings and R&D. Here’re some views and suggestions from the industry stakeholders on the scope for Self Reliant Solar India.

SUNIL BADESRA Business Head, Sungrow (India) Pvt. Ltd.

India has been one of the top growing solar markets in the world.

The clarion call by Hon’ ble PM for an Atma Nirbhar Bharat or a Self Reliant India is a timely initiative towards increasing the manufacturing base in India’ s economy. Electricity being the essential service and solar being the cheapest & fastest growing source of power generation in the country, it is well suited to drive the local manufacturing in this sector. With the visionary step and long term commitment, Sungrow had already established a 3 GW manufacturing unit in India, in 2018, which has now been the supplier of PV inverters to many landmark Indian and Global solar projects. Now Sungrow is more prepared than ever to participate in this endeavour with the following five ‘ In’ s to build a self reliant solar India.

1) Intent: The Government has already set its intent clear, first to achieve 100 GW solar by 2022 and then to achieve 450 GW Renewable Energy by 2030. This clearly shows the intent of scale to be achieved by Indian solar industry in the next decade. Sungrow is well poised to play a major role in this huge opportunity set ahead.

2) Inclusion: At present, mandatory requirement of locally produced goods in various rooftop solar tenders will be a shot in the arm for local manufacturers. The inclusion of local content in a gradual way will be a positive way forward to create a robust supply chain for the industry. Sungrow has already been working closely with local suppliers to increase the local content for its PV Inverter manufacturing.

| AUGUST ISSUE 2020

3) Investment: Fiscal incentives such as less import duties on raw materials, components, liberal export policies along with state govt supportive measures for solar manufacturing industries are need of the hour to make the locally produced goods more competitive. Such timely and prudent steps will attract more investment in India. With more investment, as the volume increases, the economy of scale will further help the price competitiveness of locally manufactured products.

4) Infrastructure: Land acquisition, accessibility in terms of better road, rail or port connectivity, and cheaper power are three major basic infrastructures required to improve the ease of business in setting up a manufacturing unit. With this, the manufacturers can set up their plants and machineries in a time bound manner. We are glad that Sungrow got necessary support from various government agencies to build a world class factory in Bengaluru, India in 2018.

5) Innovation: Innovation is the key in building superior, reliable, technologically advanced products while reducing the overall cost of the system, in any industry. Innovation of any product will also propel further innovation in the supply chain towards better components, new materials etc. Sungrow’ s 40% of the manpower in the R & D department is a clear indicator of the company' s DNA of innovation.

Sungrow has already set its Intent clear to stay Invested in India, with Inclusion of more local contents, R&D Innovation and Infrastructure expansion in coming times.

Sungrow is strongly committed to produce the indigenous products of global standards in India for the ever growing solar PV market and thereby joining hands to build a Self-Reliant INDIA. PG 30

Indi a is finally catching up to rooftop solar as a r eli able sour ce of power for industries, offices, and homes acr oss t he count r y. The Government of India has set a target of 175 G W of i nst alled renewable energy by 2022 of which solar alone i s expected to be the single lar gest component at 100 G W. Two factors are driving a stronger adopt i on of solar power in India. First, the cost of solar power has been falling steeply over t he last couple of years to around less than Rs 2.40 a unit, thus consistently inching closer t o gr i d pari ty (as compared to therm al power produced from coal and gas) against Rs 17 a unit near. The second and perhaps a m or e important reason is the changing consum er behavi or that is increasingly m oving t owar ds cleaner sources of energy. N ew and younger consumers i n Indi a today expect util i t i es and other si mi lar service providers to raise t he standards not just in term s of price competi ti veness but also their sustainabi li t y from an ecology point of view.

Self-reli ant Indi a is about -- Strong enterpri ses generating em ploym ent; empow eri ng people to com e out and fi nd soluti ons. Now , the need is that we m ake those products that are m ade in Indi a concept.

EMERGING TRENDS & TECHNOLOGY SOLAR STRUCTURE & TRACKING SYSTEMS

India is a market that has traditionally used fixed-tilt, but the growing popularity of bifacial modules, with increasingly higher power output, will help drive demand for trackers.

Developers in India have been very focused on system cost (in $/Wp), but over time a more important equation is the levelized cost of energy (LCOE), says Gaurav Mathur, Trina Solar director for India.

LCOE refers to the total capex and opex expenditure divided by the total electricity generated over the lifetime of the project.

The benefit of using trackers – rather than fixed tilt – is that they substantially increase the amount of electricity the solar farm produces by having the panels track the movement of the sun throughout the course of the day, says Mathur.

Bi-facial panels equipped with trackers can conservatively generate 1-20% more energy or even more in optimal locations with high ground reflectance he says.

It means that over the lifetime of the project, the financial gains are enormous and easily make up for the additional upfront system cost, adds Mathur.

He says if developers are using bifacial modules, which are generally more expensive than mono-facial, they really must use trackers.

“Bifacial works better with trackers because they tend to be higher from the ground and more widely spaced than fixed tilt systems, ensuring more diffuse sunlight is delivered to the underside of the modules.

There is questionable benefit in having bifacial with fixed-tilt,” because fixed-tilt solutions typically require a considerably higher than usual tilt angle to attain even relatively modest bifacial gains, which in turn increases land usage and wind loading on the structures, and therefore overall cost he adds.

Mathur says some operators in India have been reluctant to use trackers because they are concerned about maintaining trackers over the lifetime of the project, as these have moving parts.

But Mathur says because trackers have been in the market for many years now, the industry has built up its experience working with trackers and the leading solar tracker companies have a long record of reliability using performance critical components that are well proven with very low Mean Time Between Failure (MTBF) in other outdoor applications.

Before trackers come onto the market, they go through stringent product verification programs such as wind tunnel tests that test not just for standard static and dynamic loading but also for complex second order effects such as instability and buffeting – to ensure that quality is assured, says Mathur.

Trina Solar’ s trackers are also decreasing in cost – on a cost per watt basis – because the new TrinaPro Mega trackers integrate more modules, up to 120 modules per tracker as compared to around 90 previously and even more with the launch of Trina’ s 550 and 600W modules, which enable even longer strings due to their low open circuit voltage, says Mathur. TrinaPro Mega is the company’ s ‘ all-inone’ integrated solar solution for utility-scale projects incorporating 500W+ Trina Solar Vertex modules.

The 500W+ Vertex module comprises larger solar cells – 210mm in diameter as compared to 166mm for earlier modules. The new modules have multi-busbar technology to maximize light capture.

Adopting a non-destructive cutting technique for the cells to achieve smooth edges and minimise damage to cells. Trina Solar has also developed technology to reduce the space between each cell. Like with Trina Solar’ s earlier high-performance modules, Vertex uses cells that are Mono PERC. “TrinaPro Mega provides an 8-15% lower BOS cost and 3-8% increase in power generation as compared to our very first version of TrinaPro,” says Mathur.

PERSPECTIVE

HOW DATA IS TRANSFORMING THE SOLAR ENERGY SECTOR?

Generation, distribution and consumption of Solar energy are going to experience an enormous revolutionary change due to technologies.

There are several “core” technologies available today that are helping to create an efficient, productive and sustainable future.

Big data, IOT and cloud computing, Machine learning, Artificial intelligence, Augmented reality, Virtual reality, Digital Twin, Robots, Automation and Blockchain are some of the technological pillars for the revolution and are set to take solar power to new places in 2020 and beyond.

Read the opinions of our experts on How Data Is Transforming the Solar Energy Sector

RISHI SINGHAL Director, New Initiatives, The Solar Labs

The Rooftop Solar industry in India makes up only 10% of the industry size. But it has a quite complicated design process.

Initially, a meticulous pre design helps the EPC propose the best solution to a client.

Then, a detailed analysis and design of the solar rooftop system is executed. Multiple orthogonal parameters of design are connected to each other. Hence, relevant data improves quality of work.

Data impacts multiple aspects of rooftop solar design as follows: 1. Sales phase during client conversion 2. Pre-construction phase during detailed design 3. Energy simulation phase of design Availability of high quality data for these elements has improved a lot over the last decade. Therefore, the demand for higher transparency by customers. End users are now extra aware of solar technology. So, they demand precise designs with accurate techno-commercials from day 1 of their buying journey. To fulfil this need, an installer has to up their game or become obsolete.

Winning the end customer is not only a price war, it’ s transformed.

Installers can use the power of data on financial savings to convince customers of best design solutions. End users value data and are willing to pay a higher price for smarter work. Behind every great sales pitch lies an unshakeable data driven insight.

The sales cycle for solar is long and an installer can win customer’ s trust with data. Usually, the sales executive uncovers a lot of data in a site visit. Using this information, a design engineer can create designs of solar plant layout. While the traditional way involves site measurement using tape measure. It’ s a safety hazard and a laborious process. Whereas data from satellite imagery is just as good and has transformed the pre sales bid procedure. An EPC can later conduct site surveys using aerial drone imagery. This method enables capturing of important dimensional data of all roof obstacles. Height information with accuracy upto 5 cm can be extracted here. This finally results in design layouts that are extremely precise with minimum shading losses. Concurrently, delivering maximum utilization for their rooftop area. Recently data from drones has been used to determine solar potential of entire cities. It has truly enhanced our expectation of the market size and design capabilities of the users.

Finally, data used to predict energy simulation of solar plants has seen a quantum leap. We have observed the quality of simulations depend directly on the input quality of weather data. Older and free to use weather data is usually very poor in quality. Whereas the latest data from thousands of locations in India can be accessed instantly.

This data is augmented with information on air quality. Software with capability to process this information can output precise energy simulation results. Based on location, mechanical design and weather; data can drive solar adoption through the roof.

The energy sector is becoming more composite and digital technology is the need of the hour for the entire ecosystem: right from site selection, power generation forecasting, operational performance analysis to predictive maintenance. Digitization also plays a primary role in integration of renewables and preparedness for future models like demand response.

Leaving apart the data collection difficulties through variants like FTP push, Modbus / TCP (Data loggers), API’ s (Cloud) we primarily focus on diverse usage of data in transforming the Solar energy sector.

Power generation forecasting: Day ahead forecasts are typically delivered in the morning for the next day from 0 to 24 hours and updated multiple times over the rest of the day and should be delivered automatically by the forecast provider. Generation Forecasting agencies rely on numerical weather predictions, satellite data and/or statistical forecasting and filtering methods or combinations of these techniques. The statistical filtering which in turn requires a near-real-time data feed from the monitoring system to the forecast provider along with plant historical data for building the models. As a best practice, the forecast provider should also be informed about scheduled outages and the expected duration of forced outages. Availability of data from SCADA systems (Historical performance values, accurate real-time values) / IoT instruments (weather monitoring parameters) are instrumental in optimum generation forecasting which is directly linked to huge penalties (Financial performance).

Operation performance: In general data should be analyzed at various levels, plant level (portfolio level if available), inverter level & string level. The analysis should consist of various parameters at stated levels, aggregated to required time periods carefully chosen based on practical situations. Increasingly smart use of data along with relevant KPIs can unleash the misconceptions and provide guidance to the O & M team for performance excellence / benchmarking at various levels (plant, Invertors, strings etc.)

Few Key Performance Indicators (KPI) which provide Business Units with a quick reference on performance of the power plant includes Specific yield - Measure of the total energy generated per KW installed over a certain period. Calculating specific yield at inverter level also facilitates performance comparison between inverters Performance Ratio (PR) - Ratio between the actual specific yield and the theoretically possible reference yield which captures the overall effect of losses of the PV system for longer periods.

We can also use Temperature-controlled Performance ratio for shorter durations Few other KPI’ s include energy performance index and energybased availability. We can also evaluate the service team performance through intervention time, response time & resolution time based on data.

Who would have thought that if you add photovoltaic cells, Machine Learning, algorithms, and sensors, the end product would be a sustainable world? Seems quite an obscure thought, right?

But as it appears, this is true. To begin with, we all know that the invention of technology to harness the never-ending source called the sun was a big leap in the tech world, but it had a small problem, it was unreliable. And be it a human or a machine, anything which was unreliable has always been soon forgotten, the only reason we remember something even after it’ s dead or obsolete in case of technology is only when it had done something extraordinary and right now, that is something that is happening with the solar energy sector as well, it is seeing a transformation which will change the perception it had on its arrival. It could be easily said that the once prodigal, is now on the way to become the wise son.

Big data is providing the solar sector with the power to become reliable, to see the future, to automate things, to change the way businesses operate in this sector.

The introduction of data into the sector not only bought reliability to the technology but also to the people who put their money in as the demand has since been growing for these products due to them being easy to maintain and wholly automated, in India itself the solar sector is the fifth most attractive sector for investment.

The confidence in the technology has made the investors stick and bring in a boost to this once dwindling sector.

Sensors and Artificial Intelligence have made it possible to study the cloud movements and forecast weather conditions thus making it possible to prepare for the future. For example, IBM’ s Hybrid Renewable Energy Forecasting solutions, use cloudimaging technology and sky-facing cameras to predict the weather up to a month in advance. When that kind of technology is used, it can lead to an increase in renewable power generation that is stored or delivered to the grid by up to 10 percent enough to power 14,000 homes.

Data has also brought with it the ability to become self-sustaining, machine learning equipped with web platforms has made it possible for data monitoring in a way which was impossible for humans, this allowed for a pattern to be confirmed and energy consumption to be reduced or increased when necessary. This has helped to reduce unnecessary wastage of energy and helps save families substantially. In some nordic countries, the excess solar power production sometimes leads to consumers being paid to use the energy that they generated.

Big data is fundamentally changing the world we live in. The mode of power generation, pricing, and consumption are all changing, causing significant disruption in the energy sector. New smarter ways of monitoring, modelling, analyzing, and predicting energy generation and usage are helping us to achieve sustainable energy objectives as the global population faces an unprecedented environmental challenge.

In addition, I wish to express extensive usage of data in modern business scenarios like Data-driven analytics to accelerate integration of renewable energy into the modern grid Operating IREP (Integrated renewable energy projects like Solar-Wind-Hydro, Solar-wind-battery storage) projects towards renewables integration, dispatch optimization, portfolio optimization, energy & reserve co-optimization Solar plant operates at maximum capacity when electricity prices are higher rather than percentage of operational time Predictive analytics to improve inspection, maintenance scheduling, maximize performance & operations around financials rather than Kilowatts.

According to the International Energy Agency (IEA), Solar PV is well on track to reach the Sustainable Development Scenario (SDS) level by 2030, which will require electricity generation from solar PV to increase 15% annually, from 720 TWh in 2019 to almost 3300 TWh in 2030.

When you anticipate such kind of long-term growth it is very important to track the data from the field and use it as learnings to improve efficiency of PV power plants.

With technology advancements especially in Cloud storage and Internet Of Things (IOT), collecting real time data from the PV plants is easier and affordable than ever before.

The question is - are the O&M teams looking into this data, analysing it, making informed decisions or are they simply looking into alerts & alarms, attending the breakdowns and ensuring that the plant is up & running ?

Realtime data collected from the PV plants can truly transform the PV energy sector. Before setting up the project, plant designers rely heavily on Simulation tools like PVSYST. Instead they can use real data from the plants that have been operational for at least 5 years .

For sure the story might be different !

Nearly 2.5 quintillion bytes of data are generated daily, which is accelerating every year along with the growth of IoT, says a research conducted in 2019. Industries have been storing and analyzing data for decades to optimize supply chain and operations and to maximize efficiency, reduce errors. Similarly, with solar now having completed a decade since the first commercial operations, data collected over time is now transforming the way solar works.

Here are three ways to substantiate how data is transforming the solar energy sector 1. Duck Curve Geoffrey Moore, an organizational theorist, said, “Without big data, you are blind and deaf and in the middle of a freeway.” If we take this analogy for solar, then SLDC is blind, deaf, and the duck curve is 48 wheel trailer coming towards it, and it is the most significant barrier. Solar generation is at a peak when the requirement is generally lower (11 am to 3 pm), and it goes down when demand picks up in the evening (6 pm to 10 pm). It creates a unique problem for grid stability due to the demandsupply mismatch.

With no control over the weather and other variables that affect the generation, SLDC is required to manage the fluctuation.

With the use of forecasting and scheduling, SLDC can manage this better now. Further research is adding a data layer of cloud images and executing per minute basis prediction. This accuracy in prediction of generation will be quintessential in pushing one solar one world one grid.

There are several hundreds of Inverter & PV panel suppliers, each claiming they are the best. Instead of their presentations doing the selling, consider their past performance data. Monitoring over a Giga watt of PV plants, we have clearly seen few specific PV panels and Inverters outperform the rest. If you have a SCADA/Monitoring system for your plant, ask your O&M team to provide you comparison reports of all the major equipment. 3-6 months of data from these kinds of reports will help you root cause the problem in the field.

In Solar PV, most people believe data is only about generation (kwh) which is not true. You need to capture data about manual interventions, breakdowns, module cleaning operations, spares, consumables, attendance and much more. The right word is ‘ Digitisation’ . All power producers should ‘ digitize’ their plant and only then the data can not only help improve the performance of the plant but also can reduce your operational costs and save money !

THE QUESTION IS - ARE THE O&M TEAMS LOOKING INTO THIS DATA, ANALYSING IT, MAKING INFORMED DECISIONS OR ARE THEY SIMPLY LOOKING INTO ALERTS & ALARMS, ATTENDING THE BREAKDOWNS AND ENSURING THAT THE PLANT IS UP & RUNNING ?

2. Reducing Type 1 and Type 2 Errors Solar has become a very competitive market wherein tenders are won and lost in a margin of a few paise. It has put pressure on developers to get more accurate with their modeling and aggressive in cost-cutting. Hence, every decision across the value chain becomes significant for bidding and executing such projects. Currently, we are using Meternom and NASA datasets to estimate future generation from various permutations and combinations of panels with inverters and degrees of tilt. With more data gathered due to solar installation across different geography, we will use these data sets to decide on the best panel and inverter BOM choices, thus decreasing LCOE (Levelized Cost of Energy). It will reduce type 1 (Rejecting correct outcome) and type 2 (Agreeing Incorrect outcome) errors while investing or bidding for the project.

3. Industry 4.0 & Smart Meters & Smart Grids With smart homes gaining traction, data points capturing device-level data have tremendously increased. Moreover, ease of using appliances and scheduling operation times for air conditioners, washing machines, etc., have become feasible with simple coding. At the same time, it is becoming increasingly comfortable and cheaper to monitor, store, and analyze device-level energy consumption. It is essential when one considers that energy price varies as per the time of the day. Hence, with such data, one can modify consumption patterns to increase during low-cost hours and reduce during high-cost hours. However, the data play in the house would be minimal in comparison with industrial and commercial space.

As we move from 4G to 5G in telecom, Industry 4.0 is inevitable, which will bring millions of data points of all machinery and assets. And with these data points, the industry will be able to map the exact energy requirement along with its leaks. It will enable them to pursue more energy-efficient practice, which can be fulfilled by captive solar or solar along with storage solutions.

How to Use Data, AI/ML to Automate, Analyze & Improve

Performance in Solar Power Solar power is turning into a mainstream source of energy and countries are looking to harness this energy to the maximum extent possible. There are two ways to do this—first, being the innovator in solar PV technology and second, to marry available technologies to gain maximum yield.

Embracing latest technologies reduces LCOE (Levelized Cost of Electricity) or OPEX. It is important to baseline available data and measure outcomes with key metrics that impact the business of a solar power plant.

Data collection for performance analysis

Everything starts with collecting data from remote parks to a central location where analysis could be done effectively. To bring the data in a secure way without data losses demands thorough knowledge in network architecture, data storage and large-scale plant integrations.

Automated Plant Performance & Diagnostics with AI/ML Unused data is like having an unexplored mine of gold.

Using AI/ML-based recommendations can improve plant performance by 2%.

One can change from reactive to proactive and predictive maintenance by 1. Recommending right cleaning schedules and cycles 2. Analyzing maintenance effectiveness and recommending customized plans 3. Clearly categorizing losses and identifying the specific point of loss 4. Predicting asset failures with good lead times to avoid accidents and unplanned downtimes All of this can be automated through alert-based mechanism on mobile to maintenance teams and stakeholders, eliminating the need to manually analyze large chunks of data.

Drones, AI/ML for Thermal Imaging and Cleaning

DATA HAS BEEN THE BACKBONE OF THE SOLAR INDUSTRY AND IS NOW PROVING MORE CRUCIAL IN ITS TRANSFORMATION. IN THIS ARTICLE, WE HAVE FOCUSED ON

Drones are increasingly used in solar space now. Having drones deployed as part of the future workforce will save costs and time. Studies say that drones increase inspection efficiency by 97% compared to manual inspection, with a cost-saving of $1,250/MW per cleaning cycle.

With complicated deep learning and predictive algorithms, thermal images can also be analyzed deeper to understand the kind of degradations and evolving issues in power plants.

THREE SIGNIFICANT WAYS IN WHICH DATA IS AND WILL TRANSFORM THE SECTOR, BUT THERE ARE MANY MORE APPLICATIONS USED DAILY, AND THIS WILL ONLY CONTINUE TO GROW.

AI/ML in Grid Integration and Energy Forecasting

Grid stability is of highest priority. AI/ML plays a big role in forecasting dayahead energy generation and giving advanced notification of weak grid links. In countries like the USA, the local marginal price of power in real-time and dayahead market is derived using AI/ML, which clearly impacts the business revenue of IPPs who supply in the free market.

AI/ML in Energy Storage

To enhance solar to a source of base load, it is important to use energy storage technologies such as batteries.

Data collection and AI/ML helps in battery storage by 1. Understanding battery chemistries – degradation of energy charges and discharges 2. Life cycle management 3. End-of-life predictions The use of AI/ML has a wide range of opportunities to take solar PV technologies mainstream. While breakthroughs in PV technologies might proceed at a limited pace, choosing the right technology and integrating them to gain business benefits will be the need of the hour for fast-paced solar energy development.

RETINA360 is an adaptive and seamless platform that enables data integration and collaboration of parameters from any dependent sources and provides realtime insights for actionable intelligence.

A ROAD MAP FOR

ONE SUN ONE WORLD ONE GRID On October 2, 2018 in New Delhi, Prime Minister Narendra Modi, said, “We have a dream: One Sun One World One Grid”. He announced a new ‘ One Sun One World One Grid’ vision for India to replicate its global solar leadership by encouraging the phased development towards a single, globally connected, electricity grid to leverage the multiple benefits of ever-lower-cost renewable energy and diverse energy resources. Sheer size of the task of achieving the vision looks highly difficult, but it is achievable. World have already achieved such global tasks in telegraph and on the Internet. First telegraph submarine cable was laid in 1866 between the US and Europe and by 1901 the global telegraph network had covered the entire world. There is a Global Internet’ s undersea world as shown in figure-1. Micro-level examination of Internet communication reveals that it is nothing but transmission of electricity at very low voltage for transfer of data and digital communication. In a similar way, we can also envisage the worldwide connectivity of the grid to achieve OSOWOG. For the development of the global grid, we may take a clue from the development history of Indian grid. Indian grid has grown

from state grids to regional grid to national grid. In the early years, India interconnected state grids with the tie lines forming regional grids like NR, SR, WR, ER and NER grid. During later years, India started synchronising regional grids with each other through trunk lines. Today, a very well defined integrated national grid has developed, reaping the benefit of resource diversity and time diversity between the different geographic regions of India.

Worldwide, many regional interconnections are existing for the regional co-operation and exchange of power as given below:US & Canada - The US-Canadian power system has developed into a highly integrated grid. Cross-border transmission and coordination of system operations create an interconnected power system.

CASA/CAREC - Though not an association, these projects are aimed for regional energy interconnection and operation covering countries of Central Asia.

BIMTEC/SARRC - Organisations of South Asian Countries - Framework for cross border electricity transactions have been established.

Many interconnections exist and others are being developed.

Oceania - Australia, New-Zeland, Melenasia. Regional operation is yet to be established.

South-East Asia - These are developing countries and yet to have some organisations for regional cooperation.

Eastern Asia - Includes, China, Japan, Mongolia, Taiwan, North Korea, South Korea. Are not interconnected.

To achieve OSOWOG and to form a Global Grid, we need to leverage these regional associations. Wherever regional cooperation or interconnection are either not existing or are underdeveloped, these have to be strengthened. However, parallely the already established regional interconnections may be interconnected through long distance undersea cables.

T H I N K TWO-FOR-ONE ENERGY FROM PHOTONS, NOW BETTER THAN EVER

NEW RECORD EFFICIENCY FOR TANDEM SOLAR CELL TECHNOLOGY

In the twisting and turning of long organic molecules, Nati onal Renewable Energy Laboratory (NREL) researchers have found a promi si ng group of materi als for tomorrow’ s super-efficient solar cells. In a new paper i n Nature Chemi stry, NREL researchers demonstrated how a carefully desi gned molecule can efficiently split the energy imparted by one photon i nto two exci ted states and keep them separated for several mi croseconds—a long ti me at the molecular scale. By creating and then refi ni ng a model of how the molecules move and interact, the team discovered that a twi sti ng moti on gi ves the molecules the characteristics needed to i solate the tri plets. The molecular chain is usually floppy and flexible when not under i llumi nati on; but when it absorbs a photon, the chain twists around i ts central axi s and i ni ti ally stiffens, resulting in a shape that facilitates the formati on of two tri plets. The subsequent twisting that occurs after the i ni ti al process fi ni shes helps to spatially separate the two triplets, lengtheni ng thei r li fespans. By combi ning experimental and modeling approaches, the team was not only able to develop a promising energy-absorbi ng molecule, but also to explai n i ts function in detail. Now that the fundamental mechani sm i s well understood, future development and use of si milar molecules i n hi gheffi ci ency solar cells or other photoelectrochemi cal systems should be easi er.

In the fi eld of photovoltaics, intensive research is bei ng carri ed out to conti nually improve solar cell efficiency. Increasi ngly, the focus i s on tandem photovoltai cs, in whi ch high-performance solar cell materi als are brought together in vari ous combi nations i n order to use the solar spectrum even more efficiently when converting light i nto electri cal energy. Fraunhofer ISE i s now reporti ng a new record effi ci ency of 25. 9 percent for a III-V/Si tandem solar cell grown directly on si li con.

Thi s cell was produced on a low-cost si li con substrate for the fi rst ti me – marki ng an important milestone on the way to economi cal soluti ons for tandem photovoltai cs.

RENEWABLE ENERGY COULD REDUCE ASIA PACIFIC LNG PLANT EMISSIONS BY 8% Usi ng renewable energy to power liquefied natural gas (LNG) plants in Asia Pacific could reduce emissions by about 8%. Asia Pacific produces over a third of the world’ s LNG, but also generates over 50 million tonnes of carbon dioxide equivalent (MtCO2e) of emi ssi ons during liquefaction. Australian LNG proj ects account for over half or 29 MtCO2e of li quefaction emissions from LNG proj ects i n the region. Many of Asia Pacific’ s LNG faci li ti es are located in remote areas, far from the power grid. As a result, feed gas is used to generate electricity to run the plant and fuel the liquefaction process. Typically, 8% to 12% of feed gas is consumed at the plant to run these processes. Older, more inefficient plants, as well as nascent floating LNG (FLNG) vessels operate with far higher losses.

The Fraunhofer Institute for Solar Energy Systems ISE has been worki ng for many years on multi -j uncti on solar cells, in whi ch two or three sub-cells stacked on top of another absorb di fferent porti ons of the solar spectrum and convert i t i nto electrici ty. Si li con is a suitable absorber for the infrared part of the spectrum. Several mi crometer-thi n layers of III-V compound semiconductors made of elements from groups III and V of the periodic table are deposited on top of si li con.

These sub-cells effi ci ently convert the light from the ultravi olet, vi si ble and near-i nfrared parts of the spectrum into electricity. III-V semi conductor solar cells on Germanium are often used i n space as well as i n concentrator photovoltai cs. Through the development of better and more cost-effective processes i n combination wi th the use of si li con as the bottom sub-cell, the tandem technology can become accessi ble for wi de-range use in almost all photovoltai c appli cati ons i n the future. However, there is still much work to be done before thi s obj ecti ve can be achieved.

PV MODULE PRICES TO REBOUND INTO UPTREND AS GLOBAL WAFER PRICES SURGE ONCE AGAIN Polysi li con pri ces have seen continuous hikes in the past two weeks due to the explosi on at Jiangsu Zhongneng’ s chemi cal plant i n Xi nj i ang and the impact of the COVID-19 pandemi c, accordi ng to TrendForce’ s latest i nvesti gati ons. In parti cular, mono polysi li con closi ng prices i ncreased by more than 10% on average, whi ch led wafer suppliers to increase wafer pri ces. As a result of ri si ng wafer pri ces, the downswi ng i n global PV module prices rebounded i nto an uptrend instead. Trend Force analyst Sharon Chen i ndi cates that leadi ng PV wafer supplier LONGi i ncreased its wafer pri ces agai n thi s week i n response to risi ng polysi li con costs, with an average i ncrease of 7% (7. 3% in the overseas markets). However, as end-market demand has yet to recover to a suffi cient level, the increase i n global PV module prices i s proj ected to be limi ted despite thei r rebound. As endmarket demand for PV modules in Taiwan declines, module pri ce hi kes are proj ected to reach about USD 1. 5 cent/W at the most

A CLOSER LOOK AT WATERSPLITTING’S SOLAR FUEL POTENTIAL

FAST-PACED RENEWABLE ENERGY GROWTH TO DRAW SUBSTANTIAL INVESTMENTS IN INDIAN TRANSMISSION INFRASTRUCTURE

In the fight agai nst cli mate change, sci enti sts have searched for ways to replace fossil fuels with carbon-free alternatives such as hydrogen fuel. A devi ce known as a photo electri cal chemical cell (PEC) has the potenti al to produce hydrogen fuel through arti fi cial photosynthesi s, an emerging renewable energy technology that uses energy from sunlight to dri ve chemi cal reactions such as spli tti ng water i nto hydrogen and oxygen. The key to a PEC’ s success li es not only i n how well its photoelectrode reacts wi th light to produce hydrogen, but also oxygen. Few materials can do thi s well, and according to theory, an i norgani c materi al called bismuth vanadate (Bi VO4) i s a good candi date.

The Indian transmi ssi on infrastructure is li kely to grow by over 25% between 2020 and 2025, mainly driven by the rapi d growth i n the renewable capacity which has seen limi ted expansi on due to lack of infrastructure. Accordi ng to Global Data’ s estimates, the Indi an power transmi ssi on infrastructure would need an i nvestment of about INR 2-2. 5 trilli on (US$27bn-US$34bn) over the period from 2020 to 2025 to accommodate the power evacuation i nfrastructure for modernizi ng aging infrastructure and new expansion to accommodate the power from new capaci ty bui ld-up target. The Indi an renewable landscape is rapi dly changi ng and is growi ng at a consistent pace. The steep reduction in the renewable generati on costs, conducive poli cy envi ronment and avai labi li ty of investment avenues have resulted i n doubli ng the share of the Indian renewable capacity i n the capaci ty mi x to 23. 4% at the end of March 2020 from 11. 8% at end-March 2015.

T A N K ALL-INDIA ENERGY DEMAND SHOWS SIGNS OF RECOVERY In June 2020, the all-India energy demand contracted 10. 9% year on year for the fourth consecutive month to 105. 6 billi on units, whi le energy supply also decreased 10. 9% year on year, resulting i n the energy defi ci t remai ni ng at 0. 4% (June 2019: 0. 5%). The power demand declined for June 2020, ami d the COVID-19 led lockdown, on account of a decli ne i n commerci al and i ndustrial demand from maj or manufacturing states such as Maharashtra (down 17. 1%), Guj arat (down 10. 2%) and Tamil Nadu (down 10. 3%). The energy demand is showing signs of recovery as the decli ne i n power demand narrowed in June 2020 (down 10. 9%; May 2020: down 14. 9%; Apri l 2020: down 22. 3%) due to the gradual lifting of lockdown for certai n economic activiti es and an increase in domestic consumpti on wi th the extended summer season. The energy demand also showed a 2. 9% mom i mprovement over May 2020. With the contraction i n demand, electri ci ty generation (excluding renewables) also decli ned 11. 8% year on year to 99. 5 bi lli on units in June 2020 (May 2020: down 17. 7%) wi th thermal generati on decli ning 17. 7% year on year (down 21. 4%). Thermal PLF decli ned to 49. 5% i n June 2020 (May 2020: 47. 9%; June 2019: 62. 4%) on account of the lower demand. Central, state and private sector PLFs declined to 58. 7% i n June 2020 (June 2019: 67. 7%), 39. 5% (60. 8%) and 50. 8% (59. 6%), respecti vely.

Thermal PLFs were the most impacted due to the decli ne i n the power demand over 1QFY21, given the must-run status of nuclear, hydro and renewables.

UTTAR PRADESH DISCOMS COULD SAVE INR 900 CR ANNUALLY BY PURCHASING POWER FROM COST-EFFICIENT PLANTS Stri ct adherence to meri t order dispatch (MOD) could result i n potenti al savings of INR 900 crores annually for di scoms i n Uttar Pradesh, accordi ng to an i ndependent study released today by the Counci l on Energy, Envi ronment and Water (CEEW). MOD i s a process vi a whi ch di scoms pri ori ti se the purchase of power from the most costeffi ci ent plants. Currently, discoms often devi ate from MOD due to a range of i ssues i ncluding poor coal availabi li ty at some low-cost generati ng stati ons, inefficient operati onal scheduli ng, and an i nherent preference to have state-owned generators di spatch on account of flexi ble payment terms. Uttar Pradesh’ s discoms highli ghted a revenue defi ci t of INR 4500 crore in their recently filed annual revenue requi rements for FY 20-21. Power purchase costs account for 75–85 percent of the total annual expenditure of UP di scoms. Tri mmi ng down power purchase costs, especi ally adherence to MOD, would be cruci al to address thi s revenue deficit. The CEEW study, based on an assessment of the Uj wal Discom Assurance Yoj ana (UDAY) scheme, also found that di scoms in Uttar Pradesh had lost more than INR 80 pai sa on each unit of electrici ty sold i n recent years.

ECREEE PUBLISHES POLICY BRIEF ON THE IMPACT OF COVID-19 ON THE ECOWAS ENERGY SECTOR As ECOWAS countries grapple to slow the spread of the virus, they must also face the fact that without adequate energy, it is much harder to sustain measures needed to fight a virus like thi s one. Being confined without electri city, water, and fuel for cooking and other uses is the reali ty for millions i n the region. Those living in rural offgri d communities, those served by weak and unreliable grid networks, and those wi thout access to clean cooking systems are bearing the brunt of the pandemic. The pandemic has revealed even more underlying vulnerabilities in the region’ s energy sector. We have seen delays i n the implementation of energy strategies, including the postponement of planned generati on capacity and, of course, for some countries, a reduction in public revenues due to the global decline in oil prices. In addition, energy demand reduced significantly i n the industrial and economic sectors but increased in the domestic sector, creati ng a new wave of energy-vulnerable citizens and, at the same time, reiterating the fragi li ty of utilities in the region. As countries in the region try to cope with the surging numbers of infected persons, there has been a need for constant electrification of traditi onal health centres and makeshift health facilities.
