& EQBusiness Financial Clean’ Renewable Energy Alliance Launched To Expand Energy Access To 300 Million People In India

B

uilding on pioneering efforts by clean energy practitioners to expand access to affordable and reliable energy solutions for India’s “last mile” – which includes over 300 million PEOPLE who have not been reached by the national grid and do not have access to electricity – a broad alliance formed by 12 key stakeholders in the decentralized energy access sector in India today announced the launch of the Clean Energy Access Network (CLEAN) in New Delhi.

Of the 1.2 billion people without access to electricity globally, one-third are in India.

Another 800 million people in India don’t have access to modern cooking solutions. Through the collective experience and innovation of its alliance members, CLEAN will work to expand access to affordable and reliable energy services by systematically ADDRESSING the barriers that the decentralized clean energy sector in India currently FACES, supporting the global vision of the United Nations-led Sustainable Energy For All initiative to achieve universal access to modern energy by 2030. This initiative aims to achieve three interlinked objectives by 2030: “We believe that the Clean Energy Access Network is a critical effort to support India’s

decentralized clean energy sector in delivering the benefits of sustainable development to some 300 million people across India, in support of the UN’s global energy access goals. The Network’s activities will help to accelerate the delivery of modern energy services and support improvements in health care, education and economic empowerment that come with access to clean, safe, reliable and affordable energy solutions,” said Richenda Van Leeuwen, Executive Director, Energy Access, United Nations Foundation. The UN Foundation’s Energy Access Practitioner Network, along with 11 other organizations, is a founding partner of CLEAN. As an influential body for the decentralized clean energy sector in India, CLEAN will represent and advocate on behalf of the sector to important public and private stakeholders, particularly the government at the central and state levels. Among the highlights of its launch activities on April 8 is a dialogue with the Ministry of New and Renewable Energy (MNRE) in New Delhi on FINANCE and policy issues surrounding renewable energy for off-grid household and community electrification.

The Ministry of New and Renewable Energy is the central government body responsible

for renewable energy in India.

The Secretary of the MNRE, Mr Upendra Tripathy, will grace the official launch of CLEAN where he will talk about his ideas for the off-grid renewable energy sector and take the audience through some major initiatives and experiences of MNRE. Eminent practitioners working in the space of off-grid biomass and solar energy will discuss broad sectoral issues and challenges related to policy-making and access to finance; two strategy reports commissioned by CLEAN to outline the roadmap for these issues will also be launched.

CLEAN aims to address four challenges that are specific to the decentralized clean energy sector in India at present – issues around the policy and regulatory environment, limited financial access for both end USERS and enterprises, dearth of skilled capacity across various levels of competence, and technology standardization for clean energy products and services.

CLEAN will provide the FOLLOWING core services to social enterprises and other organizations in the decentralized clean energy sector in India: CLEAN will expand its membership to represent a wide spectrum of social enterprises across a range of technologies

and scales of operation – from those specializing in the sale of household renewable energy systems to enterprises that focus on the installation of communitylevel mini-grids.

The founding signatories to the network are: 1.Ashden India Collective 2.Council on Energy, Environment and Water 3.GIZ India 4.Indian Renewable Energy Federation 5.SELCO Foundation 6.Shakti Sustainable Energy Foundation 7.Small Scale Sustainable Infrastructure Development Fund 8.The Climate Group 9.The Energy and Resources Institute 10.The Nand and Jeet Khemka Foundation 11.United Nations Foundation Energy Access Practitioner Network 12.World Wide Fund for Nature - India

Esri And Safe Software Release Common Framework For Data Exchange Among Electrical Power Utilities

E

sri and Safe Software have p aired to develop and openly share a Common Information Model (CIM) template for data exchange. The template demonstrates one approach to translating network data from an Esri ArcGIS database into CIM XML format. The XML can then be shared with other enterprise systems.”The power behind a CIM is to provide a common language to share messaging among an electric utility’s information systems,” said Bill Meehan, Esri director of utility solutions.

The CIM comes in the wake of power industry deregulation

10

EQ

and smart grid emergence.

Utilities now share core network data more frequently than ever, and a CIM facilitates this. With a common format, a utility can share information internally across its enterprise systems, externally with other utilities, and externally with organizations such as regulators and independent system and regional transmission operators.A CIM is based on the International Electrotechnical Technical Commission (IEC) family of standards, IEC 61970.

The Esri-Safe Software model also promotes faster decision making internally when data can be moved quickly from geographic information system

(GIS) technology—the system of record for network data at many utilities—to destination enterprise systems, such as DMS, AMI, SCADA, OMS, and WMS. Users can download the template and test CIM XML data structures with their own data or a sample dataset that Esri and Safe Software provide.”With this template, we are providing another way for electric utilities to leverage their INVESTMENT in Esri technology,” Meehan said.The template works off of Esri’s ArcGIS (version 10.1 service pack 1 [SP1] or higher) and Safe Software’s FME software

(version 2013 or higher). The sample template consists of an FME workspace, an ArcGIS Data Interoperability extract, transform, and load (ETL) tool, and a sample dataset to guide users through testing how the translation process works. All the tools are provided as open source so users can adapt them to their needs.”Utilities can use the template as a starting point for understanding how to translate data from an Esri database to the CIM XML structure to share with other enterprise systems,” Meehan said.After exploring the sample dataset, users can also work to configure the template to work with their own network data.

olar Energy Corporation of India (SECI) has started trading of power from 24th March, 2015, thus entering into the segment of Power TRADING COMPANIES active in the Indian Power Market and ushering an era where largescale trading of unbundled RE power becomes a reality.

This was a unique transaction

of its kind as not many examples of short term inter-state trading of Renewable Energy can be found in India. SECI has been able to execute the flow of 20 MW of solar power from the state of Gujarat to the state of Odisha on short-term dayahead basis. The transaction comes under the gamut of the prestigious Jawaharlal Nehru National Solar Mission

(JNNSM) wherein SECI is the designated agency for trading of unbundled solar power for the 750 MW scheme under JNNSM Phase II, Batch I. Power from unconventional RE sources such as solar and wind poses numerous challenges in trading due to their highly intermittent nature and the inherent difficulty in accurate

forecasting. SECI intends to enter the Solar Power trading business in a big way. Apart from the power to be traded under the 750 MW scheme, plans for an additional 7000 MW are underway.

Renewables Re-Energized: Green Energy Investments Worldwide Surge 17% To $270 Billion In 2014

G

lobal investments in renewable energy rebounded strongly last year, registering a solid 17% increase after two years of declines and brushing aside the challenge from sharply lower crude OIL PRICES. Major expansion of solar installations in China and Japan and record investments in offshore wind projects in Europe helped propel global 2014 investments to $270 billion, a 17% surge from the 2013 figure of $232 billion.

It was the first annual increase in dollars invested in and committed to renewables (excluding large hydro-electric projects) in three years, a total just 3% below the alltime record of $279 billion set in 2011. The falls in the INVESTMENT figures for 2012 (to $256 billion) and 2013 (to $232 billion) were attributed in part to lower prices for renewable energy technologies due to economies of scale.

The 103GW of generating capacity added around the world made 2014 the best year ever for newly installed capacity, according to the UNEP’s 9th annual “Global Trends in Renewable Energy Investments” report, prepared by the Frankfurt School–UNEP Centre, and Bloomberg New Energy FINANCE. that every dollar invested in renewable energy bought significantly more generating capacity in 2014. The 103GW of capacity added by new renewable energy sources last year compares to 86GW in 2013, 89GW in 2012 and 81GW in 2011.

The 103GW of capacity added by renewables last year equals the energy generating capacity of all 158 nuclear power plant reactors in the USA. Wind, solar, biomass and waste-to-power, geothermal, small hydro and marine power contributed an estimated 9.1% of world electricity generation in 2014, up from 8.5% in 2013.

www.EQMagLive.com

This meant that last year the world electricity system emitted 1.3 gigatonnes of CO2 — roughly twice the emissions of the world’s airline industry — less than it would have if that 9.1% had been produced by the same fossil-dominated mix generating the other 90.9% of world power.

“Once again in 2014, renewables made up nearly half of the net power capacity added worldwide” says Achim Steiner, UN Under-Secretary-General and Executive Director of UNEP. “These climate-friendly energy technologies are now an indispensable component of the global energy mix and their importance will only increase as MARKETS mature, technology prices continue to fall and the need to rein in carbon emissions becomes ever more urgent.”

“The growing penetration of renewable generation in the world’s developing economies is one of the important and encouraging aspects of the 2014

report.”

China saw by far the biggest renewable energy investments last year — a record $83.3 billion, up 39% from 2013. The US was second at $38.3 billion, up 7% on the year (though this is below its all-time high reached in 2011). Third came Japan, at $35.7 billion, 10% higher than in 2013 and its biggest total ever.

As in previous years, the market in 2014 was dominated by record investments in solar and wind, which accounted for 92% of overall investment in renewable power and fuels.

Investment in solar jumped 25% to $149.6 billion, the second highest figure ever, while wind investment increased 11% to a record $99.5 billion. In 2014, some 49GW of wind capacity and 46GW of solar PV capacity were added worldwide, both records.

The dominant feature of the solar sector was unprecedented expansion in China and Asia.

Between them, the two Asian

& EQBusiness Financial giants invested $74.9 billion in solar in 2014, around half the world’s total.

In China, utility-scale projects of more than 1MW made up about three-quarters of the solar investment of $40 billion, which was a 45% increase on the previous year.

In Japan, on the other hand, investment was dominated by small scale projects of less than a megawatt, which accounted for 81% of a total solar investment of $34.8 billion, a 13% increase on 2013.

A boom in European offshore wind development resulted in seven $1 billion-plus projects reaching “final investment decision” stage in 2014. Among these, the $3.8 billion 600MW Gemini installation off the cost of the Netherlands was the largest non-hydro renewable energy plant to get the go-ahead anywhere in the world.

Offshore wind projects worth $18.6 billion were financed globally in 2014. This was 148% higher than the previous year and 45% higher than the next highest year, 2010. Most of this total – $16.2 billion – was in Europe with China accounting for the remaining $2.4 billion.

Other renewable energy sources did not perform so well by comparison. Biofuels fell 8% to $5.1 billion, biomass and waste-to-energy dropped 10% to $8.4 billion and small hydro was down 17% to $4.5 billion. Only geothermal bucked the trend with a 27% increase to $2.7 billion.

A salient feature of the 2014 result was the rapid expansion of renewables into new markets in developing countries, where investments jumped 36% to $131.3 billion. China with $83.3

billion, Brazil ($7.6 billion), India ($7.4 billion) and South Africa ($5.5 billion) were all in the top 10 investing countries, while more than $1 billion was invested in Indonesia, Chile, Mexico, Kenya and Turkey.

In contrast, the total renewables investment in developed economies rose only 3% to $138.9 billion.

Even accounting for the booming offshore wind sector, investments in Europe hardly changed at $57.5 billion.

Despite turnaround, challenges remain. Although 2014 was a turnaround year for renewables after two years of shrinkage, multiple challenges remain in the form of policy uncertainty, structural issues in the electricity system even in the very nature of wind and solar generation, with their dependence on breeze and sunlight.Another challenge was, at first sight, the impact of the 50%-plus collapse in the OIL PRICE in the second half of last year. According to Udo Steffens, President of the Frankfurt School of Finance and Management, however, the oil price is only likely to dampen investor confidence in parts of the sector, such as solar in oilexporting countries, and biofuels in most parts of the world.

“OIL and renewables do not directly compete for power investment dollars,” said Steffens. “Wind and solar sectors should be able to carry on flourishing, particularly if they continue to cut costs per MWh. Their long-term story is just more convincing.”Of greater concern is the erosion of investor confidence caused by increasing u n c e r t ain t y s u r r o u n din g government support policies for renewables. “Europe was the first mover in clean energy,

but it is still in a process of restructuring those early support mechanisms,” notes Michael Liebreich, Chairman of the Advisory Board for Bloomberg New Energy Finance. “In the UK and Germany we are seeing a move away from feed-in tariffs and green certificates, towards reverse auctions and subsidy caps, aimed at capping the cost of the transition to consumers.

The 2014 global investment of $270 billion in renewables followed investments of $232 billion (2013), $256 billion (2012), $279 billion (2011), $237 billion (2010), $178 billion (2009), $182 billion (2008), $154 billion (2007), $112 billion (2006), $73 billion (2005) and $45 billion (2004) — an 11-year total of $2.02 trillion (unadjusted for inflation).

“S ou t h ern Euro p e is still almost a no-go area for investors because of retroactive policy changes, most recently those affecting solar farms in Italy. In the US there is uncertainty over the future of the Production Tax Credit for wind, but costs are now so low that the sector is more insulated than in the past. Meanwhile the rooftop solar sector is becoming unstoppable.”There are also structural challenges in the electricity system as grids and utilities in many countries struggle to cope with the increasing penetration of wind and solar in the generation mix. Coping with 25% or more variable generation is more difficult for grids and utilities than managing a 5% proportion.2014 was a year of eye-catching steps forward for renewable energy with investment rallying strongly.

If these positive investment trends are to continue it is increasingly clear that major electricity market reforms will be needed of the sort that Germany is now attempting with its Energiewende energy transition.

The structural challenges needing to be overcome are not simple ones, but are of the sort that have only arisen because of the very success of renewables and their over two trillion dollars of investment mobilized since 2004.

Other highlights:

Over $2 trillion invested in renewables since 2004

Although asset finance of utility-scale renewable energy projects went up 10% to $170.7 billion, the increase for small-scale projects of less than 1MW was even bigger at 34%, to $73.5 billion. Recent sharp reductions in solar system costs are making rooftop solar a more competitive option for businesses and households looking to generate part of their own power needs. The US, Japan and China had the biggest increases in small-scale project investment.

Among other investment categories, equity raising by renewable energy companies on public markets jumped 43% in 2014 to $15.1 billion, helped by the recovery in sector share prices between mid-2012 and March 2014, and by the popularity with investors of US “yieldcos” and their European equivalents, quoted project funds.

Venture capital and private equity investment in renewable energy rallied to $2.8 billion last year, up 27% on 2013’s depressed figure, but still little more than a quarter of the record established in 2008. R&D spending on renewables edged up 2% to $11.7 billion, with corporate entities accounting for $6.6 billion and governments $5.1 billion.

& EQBusiness Financial IoT Technologies Expected To Buck Headwinds Facing Solar And Wind Industries And Drive Next Stage Of Growth, Says ABI Research

A

ccording to ABI Research, growth of the solar and wind industry will increasingly rely on adoption of IoT-based technologies and services. ABI Research expects IoT connected wind and solar installations to grow at a CAGR of 21% between 2014 and 2020 with the total number of connections growing from the almost 2 million in 2014 to 6.3 million in 2020.

“With the expected decline of government incentives, the industry fears less willingness to INVEST in solar and wind products and technologies,”

comments Eugenio Pasqua, Research Analyst. “However, IoT-based technologies and services provide the means to optimize the performance of solar and wind power generation systems and reduce production variability, two areas which detractors have historically cited as major shortcomings of renewable energy sources. In our view, the IoT is an important component fuelling the next stage of growth for the solar and wind industry.”

Key IoT-based services for solar and wind power are remote

monitoring of energy production and condition monitoring of the equipment, often coupled to cloud - based analy tics platforms. In the utility sector these solutions offer a cheaper and simpler alternative or even an additional set of features to more traditional control and monitoring systems like SCADA, and in the solar residential and commercial sectors they will play an important role both FOR SUPPLIERS and customers.

Cellular connectivity will also play an important role and is expected to garner the majority share of connections by 2020.

“Given the mix of traditional and modern solutions the market for solar and wind power remote monitoring services remains quite fragmented, with different players holding the leadership sceptre depending on the target sector and the geographical area,” adds Pasqua. Some examples are represented by Mita-Teknik for the monitoring of wind farms and ABB for both solar and wind farms, while in the non-utility sectors it’s worth mentioning Locus Energy and AlsoEnergy among the leaders in North America and Rtone and Solar-Log in Europe.

The Rockefeller Foundation Launches ‘Smart Power For Rural Development’ Initiative A US $75 million initiative to promote economic development in rural areas through access to reliable and renewable energy Launched in the presence of Shri Piyush Goyal, Honourable Minister of State for Power, Coal and New & Renewable Energy

T

he Rockefeller Foundation yesterday launched ‘Smart Power for Rural Development, an initiative that aims to bring electricity to 1000 villages over the coming three years, providing power to 1 million Indians in the states of Bihar and Uttar Pradesh. To achieve this ambitious goal, The Rockefeller Foundation is funding the creation of a new organization –‘Smart Power India’ responsible for expanding the Smart Power model which uses mini-grid technology for both lighting and productive use. Headquartered in New Delhi, and led by CEO Jaideep Mukherji, Smart Power India aims to promote economic development in rural areas by providing access to reliable energy from green sources.

The launch was marked with a ceremonial event in New Delhi attended by distinguished dignitaries, including, Shri Piyush Goyal, Minister of State for Power, Coal and New & Renewable Energy, senior officials from the Ministry of New and Renewable Energy, officials from Public Sector Utilities, senior officials from Uttar Pradesh and Bihar, Heads of telecom infrastructure companies, energy service companies, research organisations, think tanks and academia.

Speaking at the launch of initiative, Shri Piyush Goyal, Minister of Power, has commented that, “The reality of the energy sector in India is that large parts of the country have remained isolated from a basic level of comfort, a basic level of development.

The fact that The Rockefeller Foundation is investing in sustainable energy frameworks is exciting. A million people, is a lot of people, even in a country like India. If implemented effectively, and I have full confidence that it will, this initiative can have a tremendous

electricity and transforming the lives of one million people in 1000 villages in rural India.

Every step towards increasing rural access to modern energy sources can help India reach its full economic potential. We believe the provision of power will open up greater opportunities for economic development in rural areas- paving the way for a more inclusive economy. The Smart Power model we are launching today is a unique market based innovation that can support India as it achieves its ambitious electrification goals.”

The Smart Power for Rural Development initiative aligns closely with the Indian government’s vision of providing access to reliable power throughout the country and is backed by a commitment of US$ 75 million from the Rockefeller Foundation. The initiative’s focus will be on India and it aims to promote sustainable business models that deliver renewable energy and spur economic development among an unreached rural population. Smart Power India will partner with energy service companies (ESCOs), telecom tower operators, investors, nongovernmental organizations (NGOs), and government agencies to provide 1,000 villages with access to power in the next

the Smart Power model, an anchor tenant, for example a telecom company operating local cell towers, would serve as the base demand for power and make it profitable for an Energy Service Company Operator (ESCO) to build a power plant which is large enough to serve both lighting and productive loads. With this structure in place, the ESCO is willing to go into rural communities and

is able to sell power to local businesses and households – thus meeting the need for various uses of power – lighting, productive loads (such as carpenters, agricultural loads – irrigation, grinding mills) and other business needs benefiting new and future

local businesses and homes.

The provision of power to the selected villages is expected to open up significant opportunities for economic development and improving livelihoods. Those affected will see improved access to education, opportunities to trade and do business, access to key information services and

improved healthcare services – all spurred on by access to reliable energy.

Smart Power India, a new Indian led organization based in Delhi, will be The Rockefeller Foundation’s key partner in working with Energy Service Companies,

private sector partners, investors, NGOs, and the Indian government to reach the goal of bringing electricity to underserved villages in India. Smart Power India, will provide support for the entire ecosystem needed for mini-grids to be successful, sustainable, and scalable. Prior to joining Smart Power India, CEO Jaideep Mukherji spent two and a half years with d.light, a local social enterprise that works to bring affordable solar lighting devices to people in the developing world.

Mr. Mukherji has a proven track record and over 30 years of experience in innovation and market development.

Jaideep Mukherji, CEO, Smart Power India said, “After the last few years spent in the renewable energy space, I am thrilled to take on the new role as CEO of Smart Power India. The Smart Power model is an innovative solution for what has been an intractable problem in India. We have a unique opportunity at this time given that the government is supporting investments in rural electrification to spur economic development. The telecom revolution and the proliferation of cell towers, and the private sector partners looking for new avenues for investment can also address social challenges. Now is the time for India to have an energy revolution, and I believe the Smart Power model stands at the forefront of supporting that vision.”

Jinko Solar Becomes The World’s Third Largest Solar Panel Maker Exclusive Interview With Mr. Li Xiande Chairman, Jinko Solar EQ : JinkoSolar is one of the top ranked Chinese module manufacturers. How is Jinko participating in the China downstream market?

LX : We plan to triple our solar power capacity this year as the company prepares for an initial public offering of its project-development unit. We plan to complete as many as 1,000 megawatts of solar projects in China this year, compared with the 503 megawatts it owned at the end of last year. In addition, we have strong project pipeline. JinkoSolar also plans projects in South Africa and the Middle East. Not only has our utility power plant business been quite successful in China, but we extended our footprint in emerging

markets such as South Africa, Middle East, South East Asia, etc.

JinkoSolar’s business fundamentals are healthier compared to pure hardware manufacturers. Robust pipeline, development and execution capability, project diversification and strong financing provide good visibility of the years ahead.

EQ : China has set extremely ambitious goals for solar in 2015 in the country. How realistic are these goals?

What has changed in China from 2014 when the goals were missed?

LX : We this year’s goal is realistic and even a little bit conservative, we think China may install as many as a record 19 gigawatts of solar power this year.

The main reason of missing goals in 2014 is because of decentralized plant por tion.

Bu t t h e n ew definition of decentralized pv plants changed in September 2014 (ground-mounted p l a n t s b el o w 2 0MW, 35 k w are categorized as decentralized pv plants), which will enable the fulfillment of this year’s goal.

EQ : How are margins in China compared to other parts of the

24

EQ

March-April 2015

world?

LX : The gross margin of JinkoSolar in 2014 is over 22%, which keeps its leading position in industry. In general, the margins in China is better than other parts of the world thanks to the complete value chain and the best technology and production knowhow.

at HT level of 11 KV substation, under the new BESCOM Net Metering Solar Policy announced in Nov 2014. While RenXSol handled the design, engineering, project management consultancy (PMC) for the whole project, the execution was done by a KSCA approved vendor under RenXSol and KSCA guidance.

The power generated at KSCA’s roof top power plant will be sent to BESCOM Grid under the Net Metering policy, wherein only the Nett of power generated and power consumed is payable by KSCA and in case of excess solar power if given to BESCOM, then the utility will pay KSCA at Rs 9.56 per unit for such power.

Commenting on the novel initiative, Srinivas Kumar, Managing Director & CEO, RenXSol, said, “We are delighted in having partnered KSCA to build a green infrastructure and in the process have showcased to the world how un-used roof tops could be utilised productively. With cricket being a religion in the country, we

are confident KSCA’s initiative will be an eye opener in harnessing green energy and go a long way in popularising solar power, especially with several State Governments introducing net metering and open access concept.”

The solar plant is designed to generate 5.90 lakh units per year, equivalent to powering 200 AEH (All Electric Homes) households using 3 KW power annually and also saving about 600 tons of carbon dioxide emissions annually. KSCA has set an example as a stadium able to use its space for helping protect the environment for our children in the years to come. KSCA has become the first cricket stadium globally and the also first stadium in India and first net metered project in Karnataka to use solar power. We are proud of this achievement and congratulate RenXSol for the success of the project.”

Indian Farmers Could Grow Power, Not Just Crops K. S. Jayaraman

T

he Indian state of Gujarat, leading in solar energy innovations with solar parks, canal-top solar plants and roof-top solar systems, is launching yet another novel scheme to harness sunlight.

This week (6 May 2015), the state announced plans to set up four solar plants of one mega watt (MW) each on farmers’ fields. The 200 million rupees pilot project allows farmers to grow crops as usual while simultaneously generating power from sunlight from the same piece of land.

If the demonstration is found successful, the scheme will be extended to rest of the state.

Photovoltaic panels on farmlands c o ul d f e e d p ower t o t h e g rid © S. Priyadarshini “The concept of having solar photovoltaic (PV) panels over agriculture land is finally going to see the light of the day,” Thirumalachetty Harinarayana, director of Gujarat Energy Research and Management Institute (GERMI) in Ahmedabad told Nature India after the scheme was announced.

Harinarayana’s brainchild, the novel idea was proposed by GERMI last year after computer modelling studies showed that the shade cast by solar panels had no adverse impact on the growth of crops. After trying out different configurations, GERMI scientists proposed that a set of PV panels “arranged like a chess board with gaps in between” and kept about five metres above the field, is ideal for allowing enough sunlight to fall on the crops while at the same time generating electricity1.

“Thus, by laying a roof of appropriately configured photovoltaic (PV) solar panels, farmers can use their land for dual purpose rather than growing only food crops,”

www.EQMagLive.com

Harinarayana said.

The power generated by the solar panels can be used to pump water for irrigating their crops and any excess electricity generated can be sold to the power grid. In other words, farmers can augment their income by renting out their land to the government or to the solar developer who erects solar panels while they grow food crops as usual on the same land.

Farmers who feed the people might also produce electricity to feed the national power grid, says Harinarayana. “The land constraint, that currently limits the growth of solar power would be virtually removed if the new proposal to use cultivable lands is adopted on a national scale,” says Sagarkumar Agravat, scientist in-charge of solar projects in GERMI.

Two other GERMI proposals are awaiting adoption on large scale. One involves stacking two layers of solar PV panels one above the other, separated by a small distance, instead of using a single layer. Using this approach a given land area can be used to generate 70 per cent more energy than what is possible with a single layer solar panel, according to GERMI. Their second proposal, if implemented, could turn major roads into “solar highways”.

GERMI scientists earlier calculated that a PV roof cover over the 4-lane 205 kilometre long Ahmedabad–Rajkot highway can generate 104 MW of power.

Test Standards For Solar Eva Encapsulation Sheets Dr. Rajeev Goel & Shivam Goel Brij, Crosslinked EVA Sheets

1. INTRODUCTION

Solar photovoltaics has undergone massive research and development leading to steap price reductions and efficiency improvements throughout the supply chain. This combined with subsidy inputs from the government has fueled a massive growth of this industry.

As per latest MNRE report, module manufacturing currently stands at just over 2500 MW and is poised to further increase to meet the growing demand. Having said that, solar investements are still long term with paybacks of 8 years or more and hence it is important to maintain durability, reliability and at the same ensure cost effectiveness of this investment. With the accumulated expertise of more than 20 years in the EVA processing field, Brij has been supporting this industry by manufacturing high quality solar cell encapsulants.

2. PV MODULE BASICS

A Crystalline module though looks simple, is a combination of highly engineered materials working together in tandem to harness energy. Thus each and every component used affects its quality, durability and is as important as any other.

One such component is the Ethylene Vinyl Acetate (EVA) encapsulant. This transparent layer of plastomer forms a protective layer over and under the solar cells preventing water, dirt and other external impurities from contaminating the cells and at the same time ensures optical transmissivity and electrical isolation. A PV module is not only judged by its electrical performance but also by its annual degradation, and product life time. Hence a cheaper module might seem to be an attractive option today but might be packed with low 30Â

EQ

quality components leading to a short life span and hence low return on investments.

What happens when a solar panel is protected with a poor quality encapsulant?

Figure 1: Crystalline solar module construction

A variety of defects can be experienced like degradation of electrical parameters, yellowing of module surface, water ingress and delamination.

3. QUALITY ASSURANCE AND TEST STANDARDS

Product testing is a form of quality assurance in relation to product research and development. Although this process is considered as the most tedious and expensive stage of research and development; it is still imperative.

Adhesion of EVA to substrate is key to the longevity of a module throughout its operational lifetime. Low adhesion is a good indication of expired EVA or exposure to moisture during transit/storage or even improper laminating conditions.

EN 1895 & ASTM D-1876 test standards can be followed to determine the peel strength accurately. Spring balance test is often used in the industry as quick test to validate the incoming material. Values between 75 N/cm and 125 N/cm can be used as a reference for quality control.

3.1.2 Gel Content Test (Crosslinking ratio).

Gel content of EVA is a measure of degree of crosslinking of the polymer. Lower gel content indicates lower dgeree of crosslinking, which severely jeopardises the long term mechanical integrity of the module. ASTM D-2765 test standard can be followed to determine the gel content accurately. Variations of the same are often used to approximate the gel content values at shop floor level.

The standard tests for determination of quality of various module components and especialy EVA are vastly varied and sometimes ambiguous. However the following tests are generally used to define quality of the EVA encapsulant films.

3.1 ENCAPSULANT TESTS.

Some or all of these tests can be performed on the shop floor on regular basis to ensure consistamcy.

3.1.1 Peel strength (Adhesion test)

Figure 2: Soxlets extraction apparatus If encapsulant is not expired, lower gel content is generally due to lowe crosslinking and hence inappropriate laminating conditions. Gel content levels of 70% and higher are recommended for longer life-

www.EQMagLive.com

times.

3.1.3 Thermal shrinkage.

EVA films have an inherent tendency to shrink when heated at lamination temperatures, which if not controlled might lead to breakage of solar cells, mislaignment of strings, amongst other stability issues.

Shrinkage is generally caused due to process induced stresses during the manufacturing of EVA films however the rule ‘lower the shrinkage and better the encapsulant’ is not generally true due to a variety of other trade-offs. Globally, shrinkage levels of 2% or less are acceptable and are known to cause no laminating problems.

At Brij, many other tests such as optical transmittance, tensile strength, water absorption, volume resistivity etc. are performed regularly for internal quality assurance purposes. These may or may not be conducted by a module manufacturer.

3.2 MODULE TESTS.

EVA is an important ingredient of a solar module and hence it is important to test its impact on module lifetime. The following tests though performed at the module level may be impacted by the quality of encapsulant film.

3.1.1 Accelerated aging.

To simulate external environment and also accelerate the slow natural ageing process, IEC and other testing bodies have devised several laboratory tests in order to predict module output and condition at end of life. Following tests are of importance with respect to EVA encapsulant: 3.2.1.1 Damp heat test.

Determination of the ability of the module to withstand the effects of long-term exposure to humidity and heat is an important aspect of this test. The test has a standardized procedure according to IEC 61215 wherein the module is subjected to 85°C, 85% relative humidity for 1000 hrs. The damp heat test is used to determine module durability and provides a measure of the overall integrity of the module. However, this test method may be misleading to allow a statement on the overall quality of the lamination. Peel tests

www.EQMagLive.com

are essential to determine the overall quality of the lamination. It is a good test for Indian conditions comprising high humidity and temperature.

3.2.1.2 UV Testing.

Most plastomers including EVA are sensitive to UV radiation and undergo degradation on its constant exposure.

Hence it is important validate if this degradation rate is well under the prescribed limits to ensure long term stability. In this test, the module is exposed to 15 kwh/ m2 UV light within 280nm to 320nm and atleast 5kwh/m2 in 320 to 385nm spectrum at temperature of 60°C. Cerium oxide in glass is partially responsible for absorbing the UV component of spectrum and hence reducing the degradation. But use of cerium free glass for lamination may have an adverse effect on degradation rates.

3.2.1.3 Thermal Cycling.

In real scenario, solar modules specially in cold climates withstand changes in temperature and sometimes from subzero to 30-40 degrees in a single day.

This causes thermal fatigue due to continous expansion and contraction of components. IEC61215 tests this by exposing the modules to 200 cycles between -40°C to 85°C, with the cycle time not exceeding 6hrs.

ule frame. In some cases, this gradient is highly negative, causing the flow of leakage current from module frame to the cell.

This may lead to migration of impurities (Na+) from the top glass surface through EVA into the solar cell. This potential induced degradation (PID), creates local recombination sites hence decreasing the cell efficiency and module performacne.

For this test, the module is subjected to a temperature of 60°C with 85% humidity under 1000v load for 96 hours.

4.SUMMARY

A durable encapsulant requires stringent quality control, uniform compositions, and use of the best available raw materials. Even a slight deterioration of any of the properties of the encapsulant over time will impair the electrical output of the module, which is of critical importance to providing a 25 to 30 year working life of a solar module.

A good EVA film should posses high peal strength, sufficient gel content, low shrinkage, and should be able to withstand the module tests and harsh environment conditions with ease.

Generally, this is a good test to determine durability and reliability of solar cells.

3.2.1.4 Humidity Freeze.

The purpose of this test is to determine the ability of module to withstand changes in temperature in humid conditions. It checks the ingress of moisture through various layers of solar panel.

Under IEC 61215, 10 cycles of exposure to 85°C at 85% RH for first 20 hrs and -40°C without RH control for next 4 hrs are performed. It is one of the best interface tests and checks the quality of adhesion.

Through constant research and development, in-house testing laboratory and stringent quality checks, we at Brij make sure that each square meter of EVA manufactured encapsulates the modules not for 25 yrs, but for a lifetime. © Copyright Protected.

Materials MatterTM MITIGATING STRATEGIES FOR HOT SPOTS IN CRYSTALLINE SILICON SOLAR PANELS DuPont-PhotovoltaicSolutions

Hot Spots

• Bypass diodes segregate cells in groups of 20 cells. This is supposed to limit the reverse voltage across the cells to less than 10V.

H

ot spots are areas of elevated temperature affecting only part of the solar panel. They are the result of a localized decrease in efficiency, which results in lower power output and an acceleration of the materials degradation in the affected area (Fig. 1). Solar panels generate significant power and hot spots can occur when some of that power is dissipated in a localized area. Hot spots are rarely stable and will usually intensify until total failure of the panel performance in terms of electricity production and/or safety.

Hot spots in crystalline silicon solar panels represent an additional stress for the materials used in module construction. This can be temporary or permanent, depending on the type and cause of the hot spot. The

The Causes of Hot Spots

There are multiple causes of hot spots, and they can be functional or operational. The functional reasons can be divided into two areas.

• Cell mismatch occurs when cells of varying current production are connected in series.

This condition is the result of wide bins in the cell sorting process. In general, this should only mildly affect the temperature of the underperforming cells.

Figure 2. Typical electrical connection of a crystalline silicon panel with bypass diodes for hot spot protection developed to address this issue (Ref. 2).

In a crystalline silicon solar panel, the silicon cells are typically connected in series, so that each 6-inch cell produces a current of about 8 amps (A), and each voltage at about 0.6 volts (V) is added through the string to build up the power (Power = Voltage*Current).

Figure 1. Hot spots are evident in this infrared picture showing elevated temperature where the cells are damaged along the frame selection of materials with higher thermal stability can help reduce the risk of performance and safety issues associated with hot spots.

Module Design and Mitigating Strategies

The causes of hot spots and susceptibility of solar panels have been investigated in the past and test standards have been

This leads to panels with a direct electrical output of about 8A and typically 30 to 35V. • If za cell cannot generate the peak current produced around it, it will act as a power dissipation device (like a resistor). This is called reverse bias.

• A resistor dissipates power by heating up, so a cell in reverse bias will exhibit a hot spot.

• Cells may not be able to produce the current because of shadows (either cast or from soiling), or because of cell damage or inherent cell lower performance (poor cell matching).

• Cell damage can occur during the production process because the silicon cell will be subjected to many stresses in lamination and handling. The cell is about 180μm thick and is very brittle.

The cell will be transported, soldered, handled as part of a string and then laminated. Each stage subjects the cells to mechanical and/or thermal stresses. Thereafter, module transport and installation can generate further stresses on the cells which can cause them to break. In particular, it was highlighted by the Institute for Solar Energy Research Hamelin, Germany (ISFH) that transportation of the panels parallel to the ground will generate particular damage to the cells (Ref. 3).

The operational reasons for hot spots are related to the solar park design and operation and can include: • Situations where an engineering, procurement and construction (EPC) company may want to accept shading conditions in the winter (as it may only represent 10 percent of the annual production in specific areas) to increase electricity production in the summer. This means that the panel will suffer

www.EQMagLive.com

of the Panel

Figure 3. Partial shading of a panel caused by a “rooftop feature” (e.g. chimney) systematic shading of the bottom row of cells every morning and evening for several months. This is where it is particularly important to install panels with the strings of cells parallel to the ground (landscape orientation) to allow the bypass diodes to work and enable the generation of 10 percent electricity, even in winter.

• For solar installations on roofs, the topography of the roof can sometimes present a challenge. Again, the installation designersmay decide that it is acceptable for a cell to be completely shaded, thereby putting a lot of stress on the panel. This condition may not be sufficient for the bypass diode to operate, resulting in an increase in temperature which will accelerate the panel degradation. Similarly, tree or tall vegetation growth around a solar installation should be controlled to avoid partial shading conditions.

• Panels can be soiled due to dust, dirt and other contaminants during their lifetime.

It can be useful to design the parks to mitigate these sources of soiling. The operations and maintenance (O&M) company should also identify situations requiring cleaning, which means regular visits to the park. The frequency of cleaning will be heavily dependent on the climate conditions and ground surrounding the park. For example, a solar park that is cleaned in the south of Italy will usually gain 2 percent for only a few days and stabilize thereafter for many months. In this case, the cost of cleaning may not be worth the effort. A solar park in dusty desert conditions, however, can lose up to 30 percent power output if not cleaned regularly. Today the Middle East has developed dry cleaning methods to de-dust the solar panels, due to the scarcity of water in the region.

The consequences of hot spots can range from dramatic fires to accelerated aging of the materials and in most cases, we will see themore diffuse temperature increase leading to an accelerated aging of the backsheet/encapsulation material set (Fig. 4). A hot spot resulting from or leading to a short circuit between the front and the back of the cell will result in very localized high intensity heating. This type of hot spot

(PVF) film, used in a tri-layer backsheet composed of Tedlar®/PET/Tedlar® (referenced as TPT in figures 7 and 8) is well recognized to provide the best combination of electrical insulation and durability against moisture, UV and temperature degradation.

DuPont™ Tedlar® PVF film is also used in a corresponding single-sided structure (Tedlar®/ PET/Tie layer, known as TPE).

Bubbling Leads to Cracking

Figure 5. High intensity hot spots in PVDF-based backsheets can lead to fires.

Mitigating the Impact of Hot Spots

While hot spots may not be directly caused by poor material selection and may be more directly related to processing problems (from cell manufacturing to panel installation and maintenance),certain materials have been found to be more sensitive to hot spot conditions. While the hot spot condition can be temporary (such as for partial shading or soiling), it is important to select materials which can withstand the temporary occurrence of hot spots.

There are two variables which are

Figure 6. Example of catastrophic hot spot failure of interest in the backsheet to mitigate the likelihood of permanent damage.

1. The softening of the backsheet inner layer may compromise the adhesion of the insulation layer, thereby affecting the electrical insulation of the panel.

2. The smaller the thermal coefficient of expansion, the fewer stresses there are at the edges of the hot spots.

Large expansion coefficients may increase the likelihood of backsheet delamination.

The backsheet is the electrically insulating component on Figure 7. Different backsheet structures can resist melting of the inner the back of the solar layerand retain adhesion and electrical insulation for longer periods of time panel. It is usually made of several layers with a core of polyester (PET). The polyester middle layer or core layer provides the main electrical insulation function. The other layers fulfill protection and/or adhesive functions. DuPont™ TedFigure 8.

The tie layer, which is in contact with the ethylene vinyl acetate (EVA) encapsulant, is also called the inner layer.

In situations of high hot spot intensity caused by shunts or electrical arcs, no material can be expected to withstand the very high temperatures reached. Some cells may be more prone to edge shunts. Arcs can occur within the panel when the soldering bus wires are placed too close to one another inside the panel and the water saturation of the EVA reaches equilibrium with the ambient moisture levels. These situations can only be remedied at the cell selection and the panel design level and should be addressed by the panel manufacturer.

Dependence of Hot Spot Conditions on Installation Type

Cells and panels can operate at elevated temperatures for reasons other than a malfunction in the panel. Rooftop systems can create an environment where the temperature of the panel can be more than 40 °C above the ambient air tempera-

ture (Fig. 9).

The occurrence of a hot spot on a rooftop system can further accelerate the degradation and affect the electrical safety protection.

An additional challenge is that the effect of a hot spot on the backsheet will not be apparent in most cases (e.g. on pitched rooftops). System owners may have a serious electrical safety protection issue

loss means lower return on investment and a higher levelized cost of electricity (LCOE) for the system owner. While some hot spots can be remedied, others are the sign of irreversible damage to the panel.

Hot spots stress the panel materials and can eventually degrade them to the extent that not only the power of the panel is substandard, but more importantly, the safety of the panel and potentially the installation is compromised. It is important

If the panel materials have been selected carefully, mild hot spot situations resulting from partial shading or soiling should not lead to instantaneous damage of the panel. This will give the O&M team the time they need to detect these by infrared (IR) thermal inspection, for example, and to remedy the situation before significant damage can occur.

The highest melting temperature of the inner layer provides stable mechanical properties of the electrical insulation at higher temperatures.

The lowest thermal expansion coefficient reduces the stresses at the edges of the hot spot and the damage to the electrical insulation.

Ensures the highest combined UV, humidity and thermal resistance.

Conclusions

Hot spot conditions are never desirable in a solar park and are usually associated with power loss (Ref. 5). Any power

Unavailability of small size wind Turbine:

REC Market not taking off:

As such REC based RE project were not considered ‘Bankable’, in the beginning when this scheme was launched so many small investors came up aggressively and invested in small-small REC based projects while taking ‘balance sheet funding’. RECs piled up and investors had to shall out money from their core business to repay loan and interest. There are more than 1 Crore RECs unsold as on March 2015.

Plan vanilla funding:

www.EQMagLive.com

Several IPPs which emerged as multi MW investor in Indian RE market have engineered new equity and debt funding model which allowed them to leverage more, pump in lesser equity for large project, get longer repayment schedule, ECB funding at lower rate and even bridge funding for equity in some cases. On the contrary a small retail investor has to go with simple 30:70 term loan at coupon rate of not less than 11.5%. Now in reverse bidding kind of tender (typically Solar) a Large IPP can aggressively bid a tariff which a small investor can never match (even while considering accelerated benefit which IPPs cannot use and neither they bother for it!)

Negotiating Power with supplier / Vender:

Big size IPPs with penetration of foreign equity fund into their books, get more importance and access to detailed information from the supplier / project developer due the size of their contract and the ‘carrot’ they show for future multi billion contract. On the contrary a 0.5 MW investor has to settle only with the ‘leftover’.

Delay in Payments: Normally 3060 days delay in payment is something an investor can deal with but an SME having a project on its book get into trouble when 30 becomes 300.

With all challenges listed above there is still good opportunity for SMEs and small investors to take up this renewable waive. Requirement is to prudently plan the investment and scout for innovative funding ideas.

of AD benefit the decrement in the wind investment by AD investors did not stop.

Although this can be utilized and has to be prudently planned by the financial advisers.

Captive Project opportunity:

This is a chance available only with small-small plants and factories. By tying up wind/solar power for captive purpose the power cost of the factory / Production is frozen for 25 years. Renewable project becomes integral part of the production process and safeguards plant form the annual increment in the tariff to the tune of total generation. Further both Electricity Duty & Fuel Charge are exempted when wind/solar units are wheeled. An investor can get duel benefit as with increase in Energy charge the effective Duty also increase and so the saving per unit.

Country has seen debacle of UMPPs, also witnessed absolute disappearance of all big investors (specially backed by foreign) from renewable market during 2008 meltdown. Even during those days these retailers continued small-small invest & the ball kept rolling.

SMEs are growth Engines:

When double digit growth is being targeted, Govt. also has to take some initiative so that these SMEs remain in game.

Solar Roof top:

This is also gaining ground, it is expected to compliment & not supplement the captive market as both are very different from application point of view. New Ideas like ‘integrator’ approach is being experimented wherein a big Investor make various tie ups for using roof and sell the power to same company (at discounted rate) which has provided roof.

Accelerated Depreciation:

How can these SMEs ride the wave?

ast few month’s promises and series of events in Energy Sector of the country seems to be the master crafts of castles on paper but equally prospected to be the night mares in reality.

Starting with the unveiling of grand plans of capacity addition of 100GW Solar, 60GW Wind, 5 UMPPs all latest by 2025, adding to 180GW (apart from IPPs and State specific RE addition Targets) to existing 260GW. With the current peak demand just around 160GW and expected growth of 10% annually make up to 210GW. These figures seem to be reasonable enough to say that they are grandly planned for India Energy Security, but the question of the hour is whether India is financially sound enough to suit such a stitch in Capacity?

Coming to the finance requirement for such a huge capacity addition, we need at least 600,000 Crores for financing Solar and 300,000 Crores for financing wind and 100,000 Crores for central government planned UMPPs accounting for 1 Million Crores only to fund Generation Capacity addition, apart from that the required Transmission and wheeling Infrastructure require another 1 Million Crores.

Indian financial institutions require 2 Million Crore Rupees only to fund Power Sector Projects, but are banks willing to lend the amount keeping in view of the poor financial condition of the Discoms!

Stone on the Head:

38

EQ

March-April 2015

Currently the distribution companies are failing to honor PPAs and are not in a position to buy power even at Rs.4 per unit and the capacity addition of the RE Plants will increase the power procurement cost will be a curse for the distribution companies. Apart from distribution companies even the CTU have to make a doubtful investment as the Green Corridor would be charged only for a part of the day and part of the year and should be idle in the rest of the year as RE sources will not cater the needs for the whole day.

Apart from Discoms, even the Generating companies have to be cautious keeping in view of the Germany’s experience of over vibrations because of load fluctuations because of poor forecasting and scheduling of Renewable power. With 160GW of Renewable capacity in place accounts for around 40% of poorly forecast-able and poorly schedulable energy increases the load fluctuations on the generating stations.

In this regard, for the power sector as a whole, how the target achievement is going to happen and even if it happens can the power be evacuated and even if evacuated will Discoms buy this power and the increase of O&M costs and excess consumption of secondary fuel oil for increase the load by 30% and 50% in sub and super critical generating stations respectively and on the whole is this stitch going to be boon or curse for the country is the question which is continuously knocking my

doors.

Secondly, dealing with coal block auction, the union government seems to be happy with the revenue they are getting by the auction of the coal and it is said that the process of forward bidding for Steel and cement sectors is expected to fill the treasury of various governments by 80,000 Crores per year but is it suitable for the grand plan of Mr. Modi’s “Make in India”.

Steel and Cement are the key ingredients in making the “make in India” a reality and this process of forward bidding is going to increase the cost of raw material for any manufacturing process which in turn will offset the competitive advantage we have in terms of cost of electricity and human resource. This may also reflect in the increase in manufacturing index inflation which forms the king’s share in calculating WPI inflation index which may force RBI to increase the rates which may be another detour for “Make in India”.

With these doubts in place even if the whole world appreciates and India showcases its winning streak it may turn out to be winners curse.

Electricity Loss, Consumption And Concerns Shivakumar Kinni, Member, IET

A

bstractâ&#x20AC;&#x201D; Electricity is an inevitable key elementary aspect of countries development. Every year energy consumption is rapidly raising, consequently the generation capacity is unable to fulfill the demand due to the various technocommercial and socio- ecological reasons.

Now to fulfill the running demand the efficiency of utilization of electricity needs to be improved and present practice of usage is also essentially to be re-innovated to achieve energy deficit. This paper reviews the various reasons of electricity wastes and how it can be minimized, predominantly demand side and how an individual or/& community can contribute is outlined in this paper. The present indicative performance of electric supply chain, why to save electricity and how to reduce consumption have also been discussed.

INTRODUCTION

Electricity is an integral part of civilized society. All of us depending on the electricity in such an extent that even one hour power-cut can stop momentum of our life. But also electricity has prominence in the view of country economic growth for the development of industrial, agriculture and infrastructure sectors.

Being India as worldâ&#x20AC;&#x2122;s third largest producer of electricity (5% of world total)[1] with installed capacity of 250.256GW (till July 2014) yet country is facing energy deficit of 6.0% to 6.3%(till June, 2013)[2] and still thousands of villages are deprived from the electricity, millions of people are living

www.EQMagLive.com

their life under the old age lantern during night. If we see the average Per-capita Energy Consumption (PEC) of India, It is just 917 kWh (2012-13)[3] & which is even lesser than the worldwide average PEC of 2600 kWh. In comparison with other developing Asian countries like China (3298 kWh), Malaysia (4246 kWh) and Thailand (2316 kWh)[4] our PEC is far away. The per capita consumption of energy is not only indicator of economic development of the country but also point outs the availability, accessibility, affordability & energy efficiency of electricity.

Every year governments are bringing new power capacity addition plans through various policies to enhance the electricity generation in order to meet the supply- demand gap.

Govt. initiatives will help in some extent in reducing the energy shortfalls but these plans alone will not help in long run to achieve the running target of energy demand due to underlying constraints which are related to the environmental, geographical, technical & financial aspects. However, increasing the electricity generation is inevitable but at the same time utilizing energy effectively, efficiently and responsibly is even more crucial since energy is never ending necessity.

Glancing at the present energy supply chain system, the enormous amount of energy is being wasted at various steps & causing to very poor efficiency of the system. This is the most worrying and perturbative realistic fact of our current electricity system.

Fig-1: Overview of electrical power system supply chain

LOSS SCENE IN ELECTRICITY SUPPLY CHAIN

Take a look at current electricity system losses, it is indeed shocking! The different stage of system from transmission to distribution and subsequent consumption has its own efficiency owing to the losses which occurs in the components/equipment of the system. Due to the cascading efficiency the overall system efficiency is resulting to 50% of system efficiency. Because of this poor performance of electric supply chain end users are able to use only half of the energy which is being generated at power plant.

Fig-2: Typical Losses in the electrical system chain[5]

(a) Generation efficiency depends upon the type, capacity & plant utilization factors.

The same is not accounted in cascading efficiency. (b) The average T&D losses of India vary from 17% to 24% in contrast to world T&D

average loss of 15%. (c) Typical Industrial, commercial & agricultural consumption/utility efficiency. (d) Total technical losses. Commercial losses are not indicated as it differs from states to state.

For T&D loss End user may not be directly responsible but as a consumer we are also contributing to the overall system poor efficiency by adaptations of inefficient components, distributions and method of energy management systems within our premises. Today’s energy price rising situations each consumer and engineers those who are associated in one or other way can play key role in the process of enhancement of the system efficiency.

CONSUMPTION SHARE AND GROWTH Looking at the statistics of year 2011-12 consumptions growth rate of electricity is self-explanatory.

Fig-3: Sector wise energy consumption of electricity (2011-12)[6]

Fig-4: Consumption growth in different sector in 10 years (2002-12)

In last ten years the electricity consumption is soared by 42% which means overall consumption per year increment is 4.2% since 2002. Among other sectors agricultural, domestic and commercial sector energy demand has increased at much faster pace. Hence, these sectors have considerable energy saving potentials.

• Lack of awareness & importance of energy conservation • Use of Inefficient equipment/appliances • Mentality of ‘I can pay whatever I consume” thinking • Liability of nothing – getting free of cost, no fear of law & etc.

• Unmetered loads • Negligent way of handling of energy utilities • Fail to monitoring & auditing energy consumption bills

WHY WE NEED TO SAVE/CONSERVE ELECTRICITY? SYNERGY REQUIRED FOR ENERGY SAVING Today’s essential need is to find out the latest technology, innovative techniques to improve the supply chain of the entire system with the collaborative efforts from both citizens and government end.

The emphasis on the below aspects are necessary.

• Efficiency improvement in each application area • Demand side management through IT • Optimized electrical system design & technology adaptation • Strict enforcement of the penalties to dishonest consumers and officers(DISCOM/ ESCOM) • Tariff rationalization w.r.t new and sustainable energy sources • Smart metering initiatives and use of energy efficiency technology solution options available.

• Use electricity as judiciously and avoid wastage as possible as.

• Regular monitoring and auditing of our consumptions & wastage • Encouragement to sustainable home, office, educational institutions & other buildings integrated with renewable energy generation.

• Effective & timely revenue collection

WHY WE WASTE ELECTRICITY?

• To reduce electricity bills since every year the electricity price % rise is competing with our income hike %.

• Electricity is not only fuel for our daily life but also vital for countries economic growth (GDP growth).

• Reduce imports of fossil fuels as our import rate of fossil fuel is 38 %( 2012)[1] and it is increasing every year.

• Reduce impacts of fossil fuels on environment as coal based power plant emits 1.1Kg(average) of CO2 for producing 1 unit(kWh) of electricity.

•Oil, Gas & Coal are likely to last for only 20 years, 36 years & 114 years respectively as per current reserve production(R/P) ratio.

•Preserve next generation as reserves are limited; we have Oil, Gas, Coal reserves of only 0.5% , 0.6% & 7% respectively of the total world reserves.

• Fossil fuels are fatal in long run- Current electricity generation is predominately depending on of fossil fuels (71%) which includes; coal (59.6%), Gas (9%), Oil (0.52%) & Nuclear (1.9%) [2].

HOW TO REDUCE CONSUMPTION AND AVOID WASTAGE? There are many areas which possess significant amount of energy saving potentials. Few of such areas are emphasize here to understand the energy saving possibilities.

Often we do not waste electricity for any bad intentions but owing to our negligence and casual practices of electricity use causes wastes. The few probable reasons might be as given below;

The consumption system comprises 40

EQ

March-April 2015

www.EQMagLive.com

1.

Use of energy efficient lights like LED & CFL

LED consumes 02-03 times less than CFL & 6-8 times less than Incandescent (INC).

CFL consumes 04-05 times less than Incandescent. e.g.: 5W LED is equal to 15W CFL & 60W INC.

2. Use electronic chokes in place conventional

choke for lighting

Electronic chokes consumes 15-20% less energy than conventional copper chokes.E.g. Ballast losses of conventional and electronic ballast are 12W & 2W respectively.

3.

Aware before using Zero bulb

Virtually there are no such zero wattage bulbs even so-called zero bulbs also consume 10 to12W power.

4.

Automated switching & metering of street lights

Most of the street lights will be ON in many streets even in day time this causes unnecessary wastage of energy.

5.

Avoid standby/sleep mode losses - Switch off(after remote switch-off) all appliances like TV, UPS, Printer, Xerox machine, AV system, Unused Server, Computers & IT loads etc.

During night or when not using.

Using timer based automatic switching & mandatory metering helps to control the unnecessary wastage of energy.

Standby loss causes typically power loss of 10 watts per device.

Many studies revealed that 5-15% of power will be wasted due to standby loss of the appliances.

6. Use Air Conditioners at optimum temperature of 23-25°C.

Operating 23oC beyond optimum temperature setting will cause energy losses.

Each oC of increase temperature can save 3 to 5 % of energy consumed as per study by reducing ACEEE.

7.

30% energy can be saved by using electronic regulators instead of using conventional knob type regulator.

Use electronic regulator for fans

8. Use refrigerators & freezer at optimum temperature of 36-38°C for refrigerator &

0-10°C for freezer.

Optimal setting of refrigerator temperature setting reduces the energy wastages.

9.

Using washing machine with light load or under load causes waste of energy.

Use Washing machine with full load.

10. Use automatic temperature cut-off cloth Iron box

In high temperature energy consumption is high. Different cloths require different temperature for ironing. So using automated temperature cutoff shall save energy.

11. Use induction cooker than non-induction electrical cooker

10 to 15% of energy can be saved in induction cooker for same amount of heat.

12. Use of LVDC power supply in IT loads & Data

centres

10 to15% of energy can be saved by using LVDC power supply to the IT loads as in present AC to DC conversion & voltage transformation process due to cascading efficiency energy is wasted and same can be

avoided by directly feeding to the loads in DC form.

13.

Adopt green/sustainable building concepts; having natural light, ventilation as much as this avoids amount of electricity need.

The average Lightning power density (LPD) of commercial building ranges from 10 ~11W/m2 depending on the type of building area.

Lighting load also contributes increase in heating & ventilation load. e.g.: 1 W of lighting load can increase 0.4W of ventilation load requirement.150sq.ft area requires typically 1TR AC which requires approx 1.2~1.5kW power.

14.

Incorporate renewable energy source electricity options locally (solar rooftops/off grid systems)

It reduces the burden on electricity network and increases the reliability while working in combination with grid & storage system.

PF improvement helps to use optimum equipment ratings as well as reducing the power losses & voltage drop.

15.

Reactive power compensation equipment across the inductive loads such as motors, transformers & etc.

Ensuring practical PF near to unity will enhances the effectiveness of the active energy utilization. e.g.: from improving pf from 0.8 lag to 0.95 can save 15% of active energy being wasted.

16.

Irrigation pump sets metering & efficiency enhancement

Average efficiency of pump is very poor it’s in the range of 25 to 50%.

In most of the states are pump sets and unmetered and heavily subsidized.

25 to 30% of energy can be saved by agricultural pump sets though adaptation of ‘eef’ pump sets, optimizing ratings, metering’s, feeder improvisation & demand side managements.

17.

Use ‘eff’ motors

Energy efficient (eff) motors consumes 7 to 10% lesser energy compared to standard motors.

18.

Use ‘eff’ transformers

Use of energy efficient (eff) transformer < 1% losses at rated capacity reduced the same % amount of energy loss.

19.

Use of ASD/VFDs for motor rating > 5HP

30 to 60% energy can be saved depending on the type of application.

20.

Use adequate size of LT cables considering cable loss criteria

By maintaining <1% of power loss while cable sizing will help to reduce the same amount of loss.

Such many more ways can be envisaged in order to minimize the wastage. But the choice of energy efficient appliances/ equipment’s shall be mainly depends on the operational requirements, life cycle cost and Investments. Moreover, in our daily life with our attentive and deliberate approach while consumption shall help to mitigate the greater extent energy wastage.

with unprivileged peoples of our society. If

CONCLUSION Energy efficiency can be achieved with each one of our individual commitment of saving resources for forthcoming generation and willingness to share available electricity 42

we can able to minimize the losses, avoid the wastage, control the consumptions, the energy deficit can be mitigated and environmental concerns can be reduced.

Each one of us has responsibility in spreading

the awareness and understanding the criticalness of electrical energy saving while consuming. This is the time to think and act very purposefully in avoiding and minimizing the wastage of even one unit of electricity as the ‘1 unit energy saved by user is equal to 2 units energy generated’ in the power plant.

Delivering adequate water supplies is a major issue for both developing and developed countries. Lack of mains electricity, or issues with fuel supplies, can make it difficult or expensive to provide power to pump water from underground aquifers or other sources.

Photovoltaic power, created by sunlight, is the answer: and Rotomag are pioneers in this technology with our indigenous capabilities and core competence for Solar Water applications. With over 8000 installations across the country we have mastered our “100% Made In India” technology of Permanent Magnet DC Motors (PMDC) and Brush-less DC Motors (BLDC); we continue to bring in consistent innovations and improvements for our end customers.

As per the data in 2013 there are about 32,50,000 registered and installed hand pumps in remote and rural parts of India for access to deep and drinkable water. However in reality very few of them are operational due to service issues and water depths in arid conditions. In draught conditions where water levels go below 50 meters, it is extremely challenging to pump water using hand pumps. It is a very common picture of India during summer seasons where one can observe a long queue for these operational hand pumps. Many lady villagers and children have to walk over a few kilometres, carrying water pots on their head to fetch drinking water for their families.

Rotomag’s solution for Drinking Water application RDW series for extreme deep well application has been an excellent solution and a case study for remote and underdeveloped locations in India. This is an effortless solution for drinking water and moreover it brings in a great opportunity of overhead water storage eliminating any need of water monitoring and consumption pattern.

The solution offers considerable

advantages over traditional solar pump installations in terms of.

• Simple installation and guidance • Exceptional reliability • Continuous water support under arid conditions • Maximum pumping efficiency at all times – Early start late stop.

• Low on maintenance • Fully automatic operation • Excellent return on investment – Water output more than commitment!

The RDW pumps can be installed in the same bore well of that of the hand pump and requires no additional bore well or space for that matter. This solution is commonly termed as hybrid pump making it extremely easy for both manual and solar powered operation for water utilization and storage.

As a 100% Made in India and Made for India product; Rotomag’s RDW solar pump series offers several advantages making the pumps practically maintenance free.

The brush- less DC (BLDC) technology on primary basis eliminates the requirement of changing the brushes or the tedious process of removing the pump for maintenance. The most advanced and state of the art bearings and seals make sure that the pump can last for a very long duration of life before it is removed for maintenance. The stainless steel casing (SS304) ensures durability and resistance to harsh water conditions in the bore well. BLDC pumps comprise of rare eath magnets at the heart of the system.

This technology ensures much higher starting torque making it possible to run the system even under muddy water conditions.

The pumps are powered by a true maximum point power tracking (MPPT) controller ensuring maximum water delivery under all the irradiation levels.

The controller is completely seal proof (IP 65) and designed to operate under harsh environmental conditions up to 50°C which

is a reality in India during peak summer times. The MPPT controller also has all the required protections like auto ON-Off, Dry Run Protection, Overflow protection and other overload protections required or safe and long term operation of the pump.

Complete encapsulated windings and stainless steel motor shaft makes the system very light and long lasting. For example, a 3 HP pump practically weights one third as that of any traditional AC pump making it very easy for pulling out the pump for operational maintenance in rare occasions.

Proven in practice, the Rotomag’s RDW system delivers a wide range of benefits and a great future to change the scenario of Drinking Water pumps in the country. Above article depicts a case of typical installation of our RDW series pump and some real facts and testimonials in the field.

The Success Story!

Chandrapur, better known as the coal capital of the state of Maharashtra and a powerhouse with over 6600 MW of thermal power capacity supplies electricity to major Western and Central belt of India.

The location is also known for its extreme environmental conditions and deep water tables during summer seasons. In spite of having such a large capacity of power production some of the very nearby villages lack electricity and heavy load shading due to power evacuation issues.

At two of the locations near Chandrapur viz. Gughus and Rajuri; Rotomag has installed about 10 Drinking Water pumps to suffice the domestic need for drinking water. The pumps have been installed at an average water levels of 150 feet and supplied with a standard complete drinking water solution comprising of Water Pump, Modules, Structures, Balance of Systems, Overhead water tank and other piping work over the existing hand pumps as depicted in the image below:

www.EQMagLive.com

Fig.1 : Schematic of a typical DC Submercible Drinking Water Pump The typical village size of these locations where the pumps have been installed is about 150 families. With a daily requirement of about 30 to 50 liters of water per family; the pump is delivering more over 5000-7000 liters of water from the bore-wells.

Starting early in the morning at around 8 AM where water requirement and storage is at its peak the pump is sufficiently filling in 5000 liters of overhead tank. After initial hours of water requirement the system ensures that the overhead tank is filled suffice the early morning requirements of the next day.

At all the locations the villagers aver very happy and satisfied with the overall performance of the pump as this has freed their life from the hand pumps and draught conditions in peak summer where water levels are to its abyss.

Ajay jain secretary to government

In order to promote solar power projects, the government of andhra pradesh have issued orders formulating andhra pradesh solar power policy, 2012 under the policy, 34.85 Mw capacity solar power projects were only commissioned before 30th june, 2014 though it was envisaged to add 2000 mw capacity by the group of ministers constituted for the purpose of promotion of renewable energy.

This policy is applicable up to the year 2017 and the incentives were applicable only for the projects commissioned up to 30th june, 2014. Further, due to bifurcation of the state, it is felt necessary to come out with a new comprehensive policy for promotion of solar power to meet the demand for power in an environmentally sustainable manner.

Andhra pradesh is poised for rapid industrial growth driven by infrastructure investments and has also been selected by ministry of power as one of the pilot states for implementation of the 24x7 – power for all (pfa) scheme. Solar energy can become an important source in meeting the growing power requirements of the state.

Ap has large agriculture consumption constituting around 24% of the total energy consumption of the state. Solar power can also help shift the agriculture load and meet the power demand during the day time.

The state government is keen to tap the immense solar potential and promote this clean source of energy to meet the rising energy requirements of the state.

Government, after detailed discussions on the proposal vide reference 3rd cited, with various stake holders viz., Aptransco, apdiscoms, nredcap, solar power developers & solar manufacturers association hereby issue the andhra pradesh power policy, 2015 as mentioned below:

The following factors make andhra pradesh an ideal location for setting up solar power projects:

Andhra pradesh solar power policy - 2015 preamble

• Amongst the best performing power distributing companies in india (apepdcl and apspdcl).

India is blessed with abundant sunshine and solar power is expected to play a critical role in meeting the energy needs of the country in the long run. Solar power projects can be setup in a much shorter timeframe when compared to conventional power projects and the cost of solar power has become more economical today. Solar power can also help meet energy requirements for both grid connected as well as offgrid applications such as solar powered agricultural pumpsets.

Mr. Jian Xie, President of JA Solar, commented, “The reliability, power output and lifespan of solar PV modules are sometimes challenged by the severe weather conditions in coastal areas.

Achieving certification in this test again demonstrates the durability and high quality of JA Solar products. We take pride in our record of success in meeting the needs of our customers through continuous product innovation.”

Solar modules located in coastal areas are at greater risk of performance degradation and shorter lifespan due to the effect of salt mist, which can obscure glass and corrode components such as frames and junction boxes. JA Solar’s line of modules is ruggedized to withstand harsh coastal

Skytron® Energy Launches Pvguard® 2.1 For Optimized Pv Plant Performance PV supervision platform improves O&M capabilities for globally active PV plant owners skytron® energy launched a new version of its leading PV supervision software PVGuard. Thanks to a range of new features and significant improvements in data management, PVGuard 2.1 stands for best-in-class supervision and remote monitoring of PV plants.

The highlight of the upgraded PVGuard is the newly introduced dashboard for the clear display of all performance and yield characteristics of a PV plant. The Dashboard Designer enables PV plant owners and operators to design their own customized plant displays, which show at a glance exactly the information they need. With this new tool, PVGuard users can also design their own mimic diagrams suited to their individual

arrangement of plants and featuring their own branding.

“We are excited to launch the new version of our industry-leading PV

supervision platform,” says Hendrik Hoffman, Director of Software, Service and O&M at skytron® energy. “With its enhanced usability, the PVGuard 2.1 truly adds value to our customers’ operations and maintenance capabilities.”

The PVGuard 2.1 includes improvements in the way supervision data for plants in different time zones is handled in charts, tables and in the pre-defined views. This is especially important for operators with a global portfolio of solar power systems and plants spread across different regions.

The new version also includes significant improvements in the emailing functionality and allows PV plant owners to define multiple email lists for plants, each with different set of recipients. Plant operators can now configure emails to be sent at a defined time or on the basis of a triggering alarm.

PVGuard supports all inverters and energy meters in common use. The new version released today has automatically been made available to all PVGuard customers over night.
