2016 has been a tremendous year of performance for Indian power sector. The industry continues to witness strong tailwinds in terms of capacity additions and promoting renewable energy. From ensuring financial turnaround of power distribution companies (discoms) in the form of UDAY (Ujwal Discom Assurance Yojana) scheme, introducing amendments in the national tariff policy, ramping up the country’s transmission network and boosting domestic coal supply – many favourable policy and regulatory reforms which are introduced in the recent past are all set to yield positive results in the long-run. According to the power ministry, the power generation during 2016-17 (April-November, 2016) is 777.506 billion units, showing a growth rate of 4.99 per cent over the same period in previous year whereas coal based power generation during the current year is 595.124 BU, showing a growth rate of 5.92 per cent over the same period in the previous year. The country has also made great strides in the renewable energy sector. In what can be termed as the new dawn in renewable energy, India has attained fourth position in the global wind power installed capacity. Also a total 1,750 MW solar power capacity has been added in during 2016-17 till 31st October. Today, with 46.33 GW installed renewable power capacity, the renewable power has a share of about 15 per cent to the total installed capacity i.e. 307.27 GW as on 31st October 2016. “Smart City” is the next big thing as far as India’s socio-economic development is concerned. A smart city encompasses efficient integration of its each and every critical component including transportation, water networks, waste management and power grids. Power will remain an integral part in this integration. This time we discussed the prerequisites of achieving smart power in a smart city highlighting some of the key challenges with existing power distribution network and how to resolve those.

POWER UPDATE PTCUL awarded ABB India to construct a transmission substation in Uttarakhand Uttarakhand’s gross domestic product has more than doubled in the last 10 years and its booming service industry and agricultural sector are fueling the demand for electric power. To meet the rising energy needs, state utility PTCUL (Power Transmission Corporation of Uttarakhand Limited) awarded ABB India a contract to construct a transmission substation in Khandukhal, Uttarakhand. The substation has recently been successfully commissioned, and serves to evacuate power generated from the rivers of this northern Indian state and integrate it into the national grid.

Challenging logistics and terrain The remote site and hilly terrain required innovative solutions and careful planning to master the challenges of moving heavy equipment and arranging the substation on uneven grounds. The transport to site of equipment such as transformers weighing up to 120 tons was all the more difficult as roads had been damaged and bridges weakened by disastrous floods in 2012 and 2013, necessitating the reinforcement of roads and the connecting bridge at Khandukhal. Accommodating the air-insulated switchgear (AIS) substation on the hill’s slope with an elevation difference of 34 meters between the highest and the lowest points was facilitated by a customized approach to design and structure. The solution included spreading the equipment across 25 tiers with walls up to 12 meters high and 2 meters wide to stabilize the tiers of the terraced substation. “We commend the ABB team on their creative and problem-solving approach and their commitment to executing this challenging project

Terraced substation in Khandukhal, Uttarakhand at multiple tiers taking all safety measures,” said Deep Sah, Chief Engineer (Projects) at PTCUL. As part of the turnkey contract, ABB India designed, supplied, installed and commissioned the 400/220 kV substation including switchgear, power transformers as well as a reactor. Reactors are used for reactive power compensation, helping to increase energy efficiency on long transmission lines. The substation is also equipped with IEC 61850-compliant automation, protection and communication systems to enable local and remote monitoring and control of all substation assets. ABB India has previously built a 400 kV substation at Kashipur, Uttarakhand, successfully and commissioning the project on time, which laid the foundation for the award of the Khandukhal project.

Virtuaal Infra raises $5mn for hydro power projects development Green energy developer Virtuaal Infra Power Pvt Ltd announced that it has entered in to an understanding with Singapore-based Infra Co Asia Development Pte Ltd to raise 5 million (` 34 crore approx) for funding two hydro power projects in Arunachal Pradesh. “The two Compulsory Convertible Debenture (CCD) facilities of up to $1.8 Million and $3.2 Million will support Virtuaal in the development of two Run-of-River Small Hydro Projects in India’s North-Eastern state of Arunachal Pradesh. VIPL have been doing its bit to counterstrike issues of carbon foot prints with its ‘Run of the River scheme (ROR) in Arunachal Pradesh,” the company said.

The company will be producing 23 MW and 14.5 MW energy through its Keyi Hydro Power Project and Pareng Hydro Power Project respectively in the state. The association will not only be beneficial to both companies involved but will also lead to the benefit of the society at large, particularly the local population in Arunachal Pradesh. Elaborating on the significance of this association, Vikram Aggarwal, Managing Director, Virtuaal Infra Power said, “Completing the cycle of Green House gas issues and proliferating an all-inclusive green energy solution, the association with InfraCo Asia, will aid in further developing the projects undertaken by VIPL and strengthen the electricity supply in North East India.”

Allard Nooy, CEO, Infra Co Asia, said, “While our association with Virtuaal Infra Power is touted to unravel a new era in the renewable energy sector and aid our partner with its pioneering Run-of-River small hydro projects, this association also marks our entry into the India market. It will enable us to sustainably develop projects within India’s renewable energy sector. We look forward to working with Virtuaal on the execution and implementation of these projects.” These opportunities fall under InfraCo Asia’s Co-Development Program, designed to support local developers to meet their prefinancial close project development costs in South Asia and South-East Asia.

POWER UPDATE Online training program for green jobs launched

NTPC awards 50 MW turnkey order to Inox Wind

New and renewable energy ministry has launched an ambitious program of installing 100 GW of solar power under National Solar Mission by 2022 making solar energy as one of the fastest growing industry. However, there is an acute shortage of skilled and unskilled manpower at different levels to meet the demands of the growing industry. Hence, there is an urgent need for specialised training programs to develop skilled human resources in the field of Solar Photovoltaic design; installation and maintenance.

Inox Wind Limited has bagged an order for a 50 MW wind power project to be deployed in Gujarat from NTPC Ltd.

Skill Council for Green Jobs, Government of India, New Delhi is making all efforts to ensure for the proper development of training programs for the development of skilled manpower meeting specific requirements of booming solar industry under Suryamitra program. Solar Radiation Resource Assessment, National Institute of Wind Energy under Ministry of New and Renewable Energy in association with Iacharya Silicon Limited (ISL), Chennai has developed an online training program in Hindi and English under Public - Private partnership at an affordable training fee of ` 599. Skill Council for Green Jobs is one of the most recently launched initiatives aligned to the National Skill Development Mission. It is promoted by the MNRE and CII.

With around 47 GW of capacity under operations, NTPC is India’s largest energy conglomerate and this 50 MW maiden order marks its foray into wind energy generation. The move is a part of the company’s target of sourcing about 11 per cent of its planned capacity of 128 GW by 2032 from renewable energy. The project is scheduled to be commissioned by first quarter of FY 17-18 and will be executed on a turnkey basis. As part of the order, Inox Wind will supply and install 25 units of its advanced 2MW DFIG 100 rotor dia Wind Turbine Generators (WTGs) for NTPC Limited. The 100 rotor dia WTG has one of the highest swept areas that make it ideally suited to maximise returns, especially in low wind areas. Inox Wind’s 450 MW Rojmal site is one of the largest wind farms in the state of Gujarat. The common power evacuation infrastructure facilities at the site have already been commissioned. “With this new order, we will further reinforce our dominant market position in Gujarat as the leading wind energy solutions provider. We look forward to strengthening this relationship in the future by augmenting renewable power capacity for NTPC and reducing the nation’s carbon footprint” said Kailash Tarachandani, Chief Executive Officer of Inox Wind.

January 2017

Tokamak Energy grew out of the Culham Laboratory, home of JET, the world’s most powerful operating tokamak. With the advent of high temperature superconductors (HTS), the company’s founders realised that it is theoretically possible to produce a tokamak that performs similarly to existing research machines - but with a much smaller spherically-shaped reaction chamber. The controlled fusion process inside a tokamak takes place in a plasma that is held in place by a very powerful electromagnetic field. The Cobham Technical Services Opera simulation software is helping Tokamak Energy to design this magnetic confinement system.

A key step on the path to the commercial spherical tokamak is the current construction of a working prototype - the ST40 - that will be used to prove that the extreme high temperature required for fusion reactions can be achieved inside a compact tokamak. This prototype will help Tokamak Energy to investigate a self-supporting structure that is able to cope with the large internal mechanical forces generated but which minimises thermally conductive connections to the room-temperature world. A consequence of the massive copper conductors is that current density and the resulting Lorentz force density is non-uniform - necessitating a high precision simulation.

How demonetisation will make an impact on Indian power sector? The Indian power sector comprises of large corporate, private equity players, foreign direct investors, individual business houses and small scale industries. Demonetisation was a strong move from the present government to instil transparency and quality in the financial system. At an organisational level the move does not impact directly, however it will slow down the momentum in the unorganised sector. While initially it may create some slowdown, we expect the market to stabilise over the next two to three months, as the nation gears up for the budget. We also feel it was the government’s strategic decision to rule out the miscreants in bureaucracy as well. This indirectly fuels more accountability and lends an indirect thrust to the Digital India Initiative as almost all transactions that were done in the present by cash will now move towards electronic transfers making it more effective to penalise the tax defaulters as well. While the overall green energy and renewable sector will see a slow down for products in solar- and wind-powered energy segments on a short-term, the move will eventually aid in building sustainable enterprises on a long term in the country. Krishnan Rajagopalan, Head Solar Business, Anchor Electricals

India is on a trajectory of double digit growth in the next few years. We do believe that the current demonetisation exercise is a step which will help cement this. We might face few hiccups as the government takes steps to further streamline the growth by making it more inclusive and formal. We strongly believe that several initiatives like 24x7 electricity access for all, emphasis on rural electrification, move to a more digital economy, smart cities, and growing urbanisation have brought the Indian power sector at a very interesting point of growth. The hunger for growth can only be satiated by well thought out investments by the entire value chain – utilities, equipment suppliers and manufacturers. Well and truly the onus has now shifted to the industry for taking it forward to next stage of growth by leveraging the government investment and participating in the India growth story.

With demonetisation, the cash deposits at the financial institutions have significantly gone up. This should have a downward impact on the loan interest rates making the cost of capital attractive for investment in the power infrastructure projects. Also with the demonetisation guidelines allowing utility bills to be paid using the old Rs 500 and Rs 1,000 notes (prior to the Dec 31st deadline), DISCOMs should be able to collect a good portion of their long-standing unpaid bill. This incremental revenue should help fund any power-infrastructure improvements at the DISCOMs - that had been held up due to fund shortage. Rajiv Kumar, Director – Marketing, ES – India, Eaton Power Quality

Demonetisation is set to have a long term benefit in the renewable energy sector in terms of reduction in cash transactions involved in various project approvals, liaison work and movement of material. Enhanced accountability and transparency of processes will improve “clean transactions for clean energy”. Dr Sanjiv Kawishwar, Sr Vice President, ReGen Powertech

We supply copper for wire and cable industry where a lot of sales happen in cash in the retail sector. This is certainly affected due to cash crunch post demonetisation. The overall sales maybe hit by 20 per cent. We expect that in next couple of months when the things stabilise and the newer modes of payment come in to vogue, the anomaly will get stabilised and we will be back to normal.

Analysis on requirement of achieving smart power in a smart city

Smart power in Smart cities C

ontinuous power supply is a major element in the smart city development. For a continuous supply of power in the smart city it is very essential to have strong and smart transmission and distribution (T&D) systems but today’s T&D systems seems to be inadequate to meet the increasing power demand therefore leaving a question on T&D’s ability to supply adequate power to the upcoming smart cities. Supplying power to the smart cities will be a challenging task and how the masters of the power sector are going to address these challenges will be a thing to watch. On this note, the article will discuss about the requirements of achieving smart power in a smart city. It will also inform about ways to address the T&D challenges.

Requirement of smart power in a smart city

The objective of a smart city is to use digital communication and technology to optimise the usage of resources such as energy, water, and roads and infrastructure and improve

governance, transportation, health care and waste management. “From energy perspective, a smart city will be able to optimise the electricity consumption of the city by being able to record the real-time data pertaining to different residential, commercial and industrial spaces. A smart city is equipped with smart grids which facilitate this collection and transferring of electricity related data throughout the city, free from all hassles and wouldn’t even require manual labour,” informs Harish Agarwal, CEO, Supreme & Co. Pvt. Ltd. “So, an individual living in a smart city essentially would have excellent control over his or her electricity consumption and ultimately would be able to optimise the expenses incurred on the electricity bills. This not only would help curtail the uncontrolled electricity consumption but also ease the enormous pressure on the sources of electricity,” adds Agarwal. Electrical & Power Review

of that power is equally essential.” Multiple dimensions can be looked into for example, power storage is one area, and power carrying accessories is another. It is hence imperative that the electrical accessories become more energy-efficient and userfriendly as the technology takes new strides.” Harish Agarwal, CEO, Supreme & Co. Pvt. Ltd

As mentioned in the policy document from Government of India, promote cities that provide core infrastructure and give a decent quality of life to its citizens, a clean and sustainable environment and application of smart solutions. The focus is on sustainable and inclusive development. “A smart city is more or less an urban vision that includes many modern needs such as integration of multiple platforms of products and services with communication technologies and Internet of Things to manage the township in general. The prerequisite to all of this is power as all of this equipment can function only when power supply is efficient,” states Rajesh Nandwani, VP & Business Unit Head-Switchgear, Anchor Electricals. He adds, “While smart power on one hand includes usage of renewable energy to produce electricity, smart management

Sharing his views on the requirements of achieving smart power in smart city Neil Savant, Managing Director, IntuitThings says, “To achieve smart power infrastructure level changes are needed to be done to be able to remotely control as well as monitor the power consumption. This is where the discussion moves toward Internet of Things solutions. Smart home is the first step towards the infrastructure changes. Then data that is generated from each home has to be used effectively and intelligently for predictive control of power which can help save the excessive and wasteful power consumption on a city level as well as giving huge monetary saving.” Smart cities are aimed at providing a better standard of living via improved and automated mechanisms by embedding latest technologies which entail incessant supply of power. “The core of smart cities is based on the availability of reliable, affordable and consistent supply of electricity which mandates augmented generation coupled with the development of a robust transmission and distribution infrastructure, a critical success factor in achieving smart power,” states Vimal Kejriwal, MD & CEO, KEC International Ltd.

“With over 600 MW`s of solar engineering experience spread over 10 states of India; we possess the expertise to design and execute projects seamlessly, anywhere you choose to build them.”

Challenges with existing power distribution network

India faces huge power crisis due to poor power distribution network. Let us understand what the challenges that disturbs the power distribution network. While India is making a steady headway on the transmission front and the sector has witnessed commendable growth over the last few years with substantial capacity additions, evacuation of power is still a concern in India. Kejriwal believes that India’s T&D network is poor in meeting the power demands and is plaguing the sector for years. He says, “The existing T&D network is inadequate to meet the increasing demand and load patterns. In addition, T&D losses are plaguing the sector since a long time. These losses inherent to T&D systems include losses incurred while transmitting power from sources of supply to points of distribution and ultimately to final consumers; commercial losses also being accounted for in this.” In India, T&D losses account for as high as 23 per cent of the total electricity generated as compared to countries like Singapore, Malaysia and other developed countries wherein the losses are as low as ranging from 5-8 per cent. “These losses can be reduced by strengthening and upgrading the T&D infrastructure combined with proper tracking and auditing which would definitely ensure reduced loss levels,” opines Kejriwal. Pointing out on the challenges with existing power distribution network Agarwal says, “With existing power distribution network, there is a lot of power that is not being used, which can be used by those regions which have a shortage of power supply. On the other hand, there may be a system failure in another power distribution network, when the actual power consumption is consistently around the total capacity provided to that region, and sometimes even crosses the maximum capacity.” Existing power distribution network used either an electromechanical meter (with a rotating disk to record the electricity consumption) or an electronic meter (with digital figures) at our houses, offices or any other property to measure our electricity usage. Typically, at the end of the month (or months) a representative of the utility comes to the property, observes the reading in the meter and subsequently we get the

“As far as the customers are concerned, there does not seem to be any problem with this mechanism. But still, since manual labour is involved, there are bound to be some errors and irregularities. In order to minimise the chances and number of mistakes and maximise the efficiency and performance of the whole system, smart meters step in the picture,” suggests Agarwal. As per Savant current challenges include physically unsecured network, virtually unsecured network against internet hacks, over burdening the existing legacy network infrastructure to meet ever increasing demand, last mile coverage of the network to provide power to each household in rural India. On the other hand Nandwani believes, the existing power distribution network has huge gaps in terms of power and infrastructure management. The main challenge involves power distribution, especially in peak hours. At the onset of summer itself, one sees power-cuts. While lack of proper infrastructure and scarcity of resources is one problem, other involves conserving energy overall. The government’s initiatives such as promoting LED, impetus and importance given to optimise renewable energy will definitely progress the situation soon. This will ensure that maximum parts of the country get access to grid electricity as well. How to address these challenges

Every problem has its solution. In order to have smart T&D network it is necessary to solve issues relevant to it. On this note, experts have suggested on how these issue will be addressed. Agarwal believes that smart grids present an elegant solution to this problem. Since the whole process of power transmission and data collection is automated, when a smart grid observes that there is a skewness in the electricity consumption of the two regions, it automatically re-distributes the power according to the usage of the regions, thereby removing any imbalance in the electricity distribution and consumption and saving a lot of energy, by minimising the scope of wastage. Interconnection planning and analysis activities create greater certainty with respect to future generation, including

The existing T&D network is inadequate to meet the increasing demand and load patterns. In addition, T&D losses are plaguing the sector since a long time.

identifying transmission requirements under a broad range of alternative electricity futures (e.g., intensive application of demand-side technologies) and developing long-term interconnection-wide transmission expansion plans. “Smart grids have the demand response capacity to strike a balance between power consumption and supply. Besides this, smart grids can integrate new energy sources like solar and wind with traditional sources. This will enable the citizens of smart cities to eventually integrate their solar or wind systems with the grid and start feeding unused power into the grid,” adds Agarwal. Smart meters facilitate real-time pricing, automated recording of the electricity consumption and a complete abolition of errors due to manual readings and reduce labour cost and enable instant fault detection. Kejriwal observes that the government is taking efforts and doing a lot of investments as well. He says that the good part is that, a lot of progress is unfolding as dedicated efforts are being undertaken by the Indian government for improving the transmission network in India. PGCIL which mainly owns and operates inter-state lines has already made huge investments for the development of inter-state networks and is managing these lines efficiently. On the other hand, the development of intra-state lines is under progress with huge CAPEX planned by many of the SEBs. The sector is also witnessing enhanced private participation. Further, in order to strengthen and upgrade the transmission network numerous schemes have been devised like Integrated Power Distribution Scheme for rural and semi-urban areas and Deen Dayal Upadhyaya Gram Jyoti Yojana for feeder separation for agricultural populace. A series of conducive policies and measures are rolled out as well as efforts are on towards achieving the mission of ‘One Nation, One Grid, One Price’.

have been enhanced for land cost which has provided some relief to the land acquisition issue. However, more thrust is required in this area. Some suggestions would be awarding projects by way of plug and play mode where all the approvals are secured before the project is awarded, adopting alternate and improved technologies like Gas Insulated Lines etc. In conclusion, though the sector has gained significant momentum, for fast tracking the pace of its development, it is imperative that more steps are taken for speedy resolution of the issues. Advising on how to solve the T&D issue Savant says, “To address these issues we need to start first from the last mile coverage in rural India. Creating and providing clean and sustainable energy is the need of the hour. Once we produce clean energy wastage needs to be reduced considerably with the help of automation. That is where things get into smart power control and regulation. Also, it is very important to be able to measure and monitor the power distribution network parameters to be able to take prognostic decisions before or while something’s goes wrong. This data needs to be stored for mining for future predictive behaviour and planning.” According to Nandwani the smart way to address these challenges is to make use smart switchgears. He says, “As the saying of ‘A penny saved is a penny earned’ applies in this domain too. Using energy-efficient appliances and electrical accessories will pave a way towards conserving power. Switchgear can be used to control heavy appliances effectively ensuring their security of operations. Smart switchgear and control gear is the next leg to the current switchgear industry where switchgear functions would be more intuitive as well.” Domain experts

“Significant improvements are also transpiring on project execution front resulting into lowering of the execution timelines for T&D projects from the traditional 36 months to 12-18 months, which is a remarkable achievement. Some our recent projects have a stipulated condition of project completion in a time span of 12 months,” Kejriwal.

Panasonic is known for manufacturing most advanced switchgear range. In 2012, Anchor has introduced some switchgear products under Panasonic brand such as MCBs, RCCBs, isolators and now also distribution boards. Panasonic MCB boasts three level indication feature, on-off and trip making it easier to identify circuit fault. Anchor will be introducing a new range of products for the commercial premises soon.

Albeit, on the ground level some issues still prevail, like the pace of execution of some T&D projects has been impacted due to various factors such as ROW issues, end users (like power plants) not being ready etc, which leads to delay in project completion schedules. This creates an additional burden on the contractors by way of time and cost overruns, mobilisation issues etc. There has to be a mechanism in place which will resolve these ground level issues. The Indian government is conscious of this fact and there have been changes in the approval processes for environmental clearances whereby the first stage approvals have been eased. Also compensation levels

KEC International Ltd is $ 1.4 billion Infrastructure EPC company and major in power transmission space. The company has been powering significant infrastructure development across India and has played a vital role in the development of critical evacuation infrastructure including HVDC transmission line projects of up to 1,200 kV. Its strong project management capabilities, robust engineering and design credentials, exceptional manufacturing expertise and outstanding testing prowess reap in benefits like accelerated project deliveries leading to expediting the socio-economic progress and development of the region in concern.

Gearing up for smart city projects

Industry players are in queue for working in smart city projects. Whereas some have already started working on it. Sharing his views on the contribution for smart city Nandwani says, “We are members of smart city council and looking actively at the smart city projects for some of our state-of-the-art range of products in the energy generation and smart lighting.” Smart grid project implementation at Puducherry by installation of smart meters was the first step by Supreme & Co. Pvt. Ltd towards smart grid. It has also developed remote monitoring system which can feed data from various smart instruments installed in the T&D line at remote location to integrate with the central server and SCADA. The company has done extensive work on GIS and worked on GIS based indexing of electricity consumer and codified asset database on the electrical system network for smart city project Puducherry. “Renewable energy integration through rooftop solar and smart street lightning system is key area of focus for us. We are also doing research on introducing and implementing LVDC system both grid connected as well as off grid since most of the power equipment and storing devices run on DC voltage system,” informs Agarwal. IntuitThings has started work with a progressive builder who is keen on a zero emission sustainable smart city where it is supporting in power monitoring of their model building for them to able to estimate and plan the sustainable and clean sources of power for their township. Next steps would be to have the homes installed with its smart home system to be able to monitor, control and hence regulate power under a desired limit remotely and automatically.

Power outages due to Transmission tower failures and DT failures can be resolved by Supreme & Co. Pvt. Ltd ERS (Emergency Restoration System) Towers and MSS (Mobile Substation). These solutions will help to reduce the down time and provide reliable power to the consumer effectively. It will also help the dynamic upgrading of power infrastructure with minimal downtime. Compact Transmission Line (CTL) solution is another area of expertise where it will help the smart cites to cope up with the need of excess power requirement using the same footprint transmitting power at higher voltage. Solutions being provided for CTL are pole type structures, insulated crossarm, HTLS conductor and interphase spacer.

This will regulate power not just at apartment level but also at the society level and in turn at city level thereby putting less burden on the source as well as distribution network. This will also help in monitoring the source as well as destination power consumption thereby guesstimating if there is loss of power efficiency above a limit where corrective actions can be taken to improve the loss the efficiency. “When we are able to monitor the power generation as well as consumption and control it as well we get a total control of the power system and hence possibilities of large scale monitory as well as green house savings opens up and can help in slowing down the rapidly increasing climate changes that could have higher devastating effects on planet earth,” says Savant.

IntuitThings is a smart IOT solutions company that have domain expertise in monitoring, control and regulation of power. It is a end to end solutions company that is agile in the solutions that it offer. The company understand the requirements and design and implement solutions for smart monitoring and control of power.

Smart cities clearly appear to be a good opportunity for KEC International’s civil, cabling, solar and power transmission and distribution businesses. It is keenly watching the developments in this space and as and when there is good opportunity the company will tap it.

ePowering the Future Cities An analysis on how smart meters can help cities to become smart

A

smart meter is an electronic measurement device installed by the utility to maintain a two-way communication between the consumer and the utility and also manage the electrical system of the consumer. “A smart meter is capable of communicating the real time energyconsumption of an electrical system in very short intervals of time to the connected utility,” explains Dileep AK, AGM - Sales & BD, Elmeasure.

The government plans to spend over ` 3 lakh crore to recast 100 cities, improving the existing infrastructure, which will translate in increased demand for electrical equipment in India. During 2016-2020, the overall market for electricity meters is expected to grow at a CAGR of 11.5 per cent, with prepayment of smart meters expected to grow more than the overall growth rate, at a CAGR of 5.3 per cent. However, Gautam Seth, Joint MD, HPL Electric & Power Ltd observes, “The market for meters is expected to witness explosive growth subsequent to 2022, when the proposed civil works for smart cities and smart grids will near completion, paving way for a robust demand for smart meters.”

Reliable 24/7 and affordable energy supply is the life line of a smart city. According to Babu Babel, Joint Managing Director, Secure Meters Ltd, “Smart meters will help monitor and manage the energy consumption effectively and engage the end user. Effective billing and collection will be helped. It will improve relationship between the smart utilities and smart citizens.” One of the goals of smart cities is to make the usage information flow regularly, flawlessly, and without manual intervention to central governing and planning bodies. Explaining the utilisation of smart meters in the context of smart city Dhananjay Kulkarni, COO, Maven Systems Pvt Ltd said, “Information about electricity usage collected every hour is crucial for demand planning. With hourly data collected over the year, it becomes possible to forecast the daily and hourly demand based on season (summer / winter), festivals (like Diwali and Christmas), time of day and a combination of these. Smart metering infrastructure which allows reading of several thousand meters every hour is crucial for this to happen.” S. C. Bhargava, Senior Vice President, L&T Electrical & Automation avers that energy efficiency, energy conservation and renewable energy integration are some of the cornerstones of smart cities.

meters, with their features of Interval Data, two-way remote communication, import/export energy registers and Demand Response Messaging through in-home display, aid meeting this objective.” The granularity of data that can be collected from the meter enables the utility to redistribute the loads based on proper load studies thus reducing the chances of breakdown. Real-time pricing helps in peak-load saving (i.e. flattening of demand curve) thus avoids the need for addition of capacity only to take care of peak loads. The power fail alerts allows the utility to take immediate corrective action to correct power outages. At the same time, tamper alerts sent by the meters can be used by the utility to take decisive and deterrent action against unscrupulous consumers.

Conclusion Smart cities initiative envisages having a smart utility in place of traditional utility or discom. A smart utility will have the ability to control, intervene and optimise the electricity consumption of the city by being able to record the realtime data pertaining to different residential, commercial and industrial spaces and keeping a close watch on it. The smart utility therefore has to be equipped with smart grids which facilitate this collection and transferring of electricity related data throughout the city, free from all hassles without manual intervention. Smart grid obviously achieves this function by using smart meters. According to Jitendra K Agarwal of Genus Power Infrastructures Ltd, “An individual living in a smart city essentially would have excellent control over his/her electricity consumption and ultimately would be able to optimise the expenses incurred on the electricity bills. This not only would help curb the unbridled electricity consumption but also ease the enormous pressure on the sources of electricity. Thus the smart meter is an irreplaceable component for realising smart city dream.”  Electrical & Power Review

T&D sector can expect better growth in the short as well as medium term. -Sanjay Bhagat, VP & BU Head - TLT EPC, Bajaj Electricals Ltd

As transmission and distribution operations constitute major part of their EPC business, Sanjay Bhagat, VP & BU Head - TLT EPC, Bajaj Electricals Ltd expects double digit growth in the topline of EPC segment.

30

january 2017

Expect double-digit growth in topline of EPC in FY17: Bajaj Electricals What are the projections for your business? As T&D operations constitute major part of our EPC business, we expect double digit growth in the topline of EPC segment of BEL.

Could you give us a brief overview of the year gone by? The year gone by was a mixed one. While, as a nation, we are facing surplus generation scenario, a lot of ground work still needs to be done in transmission and distribution (T&D) sector to improve last mile connectivity. Focus remains on T&D sector to ensure availability of reliable and affordable power to the end consumers.

What are some of the major potential areas that will drive the growth in next one year or so? Next year, a few major contracts related to transmission sector under TBCB scheme shall be finalised. Moreover we also expect extra liquidity in market due to demonetisation drive. Hopefully, this extra liquidity will help in making funds available for infrastructure industry in general. Therefore, T&D sector can expect better growth in the short as well as medium term.

What is your current order book position? As a part of major reform process in power sector, there is shift to Tariff Based Competitive Bidding (TBCB). As a result a few published tenders of transmission lines were cancelled. These are expected to be refloated again this year. However as we have diversified portfolio including substations and monopoles, it has not affected us adversely. Presently, we have healthier unexecuted order book compared to last year.

What about ‘smart city’ mission? ‘Smart city’ mission means wholesome development. It will not only mean better opportunities for T&D sector, but also for other products and services spanning across many sectors. We are equally excited about more demand of galvanised monopoles structures for T&D, telecom, illumination, signage and other applications, as these structures are not only aesthetically pleasing but also meet the lesser footprint requirements for the smart city.

What does next year look like for the Indian electrical equipment industry? With excess generation scenario, more focus is likely to be on transportation of generated power to the consumers, which will result in growth in T&D sector. Therefore, Indian electrical equipment industry can expect better growth next year.

Are there any challenges too? Major challenges are increasing raw material and fuel prices, lack of availability of skilled labour and industry wide excess capacity built-up. Also slower execution of infrastructure projects due to various issues such as fund availability and Right of Way (ROW) is an area of grave concern. Electrical & Power Review

Power Quality for Smart Grid: An imperative in growing Indian power sector Today, the electricity distribution industry is grappling with an unprecedented array of challenges, ranging from a supply-demand gap to rising costs. The distribution network today has become vulnerable and is increasingly governed by bi-directional power flows and fluctuating voltages determined by customer load & generation. Left with an ageing infrastructure, the conventional distribution network needs an upgrade and the smart grid phenomenon seems to be the way forward.

The smart grid will be at the heart of tomorrow’s connected world underlining the ‘Quality’ of life for each one of us, hence conscious planning and implementation of the smart grid with attention to good power quality environment is the only way forward. Country

Smart Grid Initiatives in Developing Countries

USA

USA has more than 130 ongoing smart grids projects, spread across 44 states and 2 territories. It has made significant investments for upgrading the grids and distribution automation. A fund of $11 billion has been set aside for the creation of smart grids. Also, the Smart Grid Investment Grant program (SGIG) had provided close to $3 billion for smart metering, $1 billion for electricity systems, and roughly a half billion dollars each for electric transmission and customer systems. More than 10.8 million smart meters have been installed which is 8 per cent of total meters and 287 networked phasor measurement units (PMUs) are in place to check PQ. United States’ electric utilities plan to install 60 million smart meters by 2020.

European Union

European Union has around 459 ongoing smart grid projects in 28 member states and has a budget of around €3.15 billion spread across 578 sites. Around 200 million smart meters in Europe (72 per cent of EU customers) are expected to be deployed by 2020 with an estimated investment of €35 billion. Germany has taken a lead in Europe for implementing smart grid projects. It has taken an E-Energy – The Internet of Energy initiative and has mandated all buildings to be equipped with Smart Meters from 2010 and Demand Response program from 2011. It has estimated to invest €40 Billion in Smart Grid by 2020.

Japan

Japan has initiated 4 smart grid pilot projects with an investment of 12.6 billion Yen (USD 157 million). Tokyo Electric Power Company (TEPCO) has announced a plan of installing 17 million smart meters in households by 2018 and 27 million meters by 2023.

China

China has estimated an investment of $100.8 billion for smart grid implementation. It is currently focusing on the creation of a large capacity interconnected transmission backbone to transfer bulk power and to accommodate fast growing electricity demand. It has set to rollout 360 million smart meters by 2030 and is investing heavily in more efficient distribution transformers.

South Korea

South Korea plans to spend $24 billion over the next two decades on around 10 Smart Grids projects to make electricity distribution more efficient. It plans to install total 24 million smart meters by 2020.

While the understanding of smart grid is different for different stakeholders, like five blind men deciphering an elephant in the room, however the fact is that we are in the midst of a revolution that can transform our conventional grid into an efficient and intelligent one. For most utilities, smart grid is about installing smart meters and establishing an outage management system, whereas for consumers and industries, the smarter grid would be of little value unless marked with highly reliable supply and resulting in optimized monthly electricity bills. Effective implementation of the smart grid involves advanced distribution network automation integrating the power network with ICT technologies and electronic devices. Such automation demands adequate power quality to guarantee the necessary compatibility between all equipment connected to the smart grid. Power quality, therefore, is an important issue for the successful and efficient operation of existing as well as future grids. In addition, the use of sophisticated equipment (particularly DC) by consumers is also putting an additional responsibility on the network operator to maintain quality of supply as per the set standards. Thus, this article attempts to discuss the importance of addressing the quality of supply requirements while implementing smart grid projects and leveraging these projects as an opportunity to improve and efficiently manage power quality.

Guest Column Power Quality for Smart Grid: An imperative in growing Indian power sector 32 f

Effective realisation of smart grid requires advanced distribution network automation, which includes Substation automation, advanced metering infrastructure (AMI), outage management system, distribution management functions like voltage control or reactive power (VAR) control, harmonics detection and analysis, etc.

occasions where Regulator has incentivised or penalised discoms for non-compliance on these parameters. Even reporting of such reliability indices are of doubtful integrity at times. Utilities that consider installing smart meters need to also focus more holistically on the overall quality of supply of smart grids than merely installing smart meters.

Such automation involves the use of power electronic devices and converters, which are highly sensitive to both voltage quality as well as harmonic distortion. The use of power electronic interfaced, often to achieve energy efficiency objectives, loads has considerably increased with the proliferation of personal computers, TV sets, adjustable speed motor drives for pumps or air conditioning appliances, etc. When these loads are connected to the grid, harmonics produced by these nonlinear loads are injected back into the supply systems. These currents interact adversely with a wide range of power system equipment thereby causing additional losses, overheating and overloading. Harmonics, one of the fastest growing PQ issues, are caused by the non-linearity of customer loads. Harmonics is a form of disturbance in electrical network, which influences and affects the operations of assets like transformers, feeders, etc. These harmonics also cause interference with telecommunication lines and errors in power metering, malfunction of data processing equipment, nuisance tripping of protective devices, etc. The smart grids equipment like communication devices, routers, relays, switches, capacitors, smart-meters, servers, sensors, etc. are very much vulnerable to harmonics and voltage, and hence maintaining the quality of supply plays an important role in implementation of smart grid.

The table above shows the Smart Grid initiatives by some of the developed nations, thereby helping them improve quality of supply.

Smart Grid initiatives in India and developed nations Worldwide, national governments are encouraging smart grid initiatives as a cost effective way to modernise their power distribution infrastructure. India ranks third among the top ten countries in smart grid investments and has announced substantial smart meter rollout projects with a plan for more than 130 million smart meters by 2020 with an investment of $1billion. However, the existing policy and regulatory framework are typically designed to deal with the existing network. With the move towards the smart grid, these policies must evolve in order to encourage incentives for investments. Policy makers need to take some immediate action in certain critical areas like standards and regulations for its effective implementation. The Government of India (GoI) has appointed India Smart Grid Task Force (ISGTF) and India Smart Grid Forum (ISGF) with the prime objective of accelerating development of smart grid technologies in the Indian power sector by bringing together all the key stakeholders and enabling technologies. Along with policies on smart grid, it is essential and important to focus on improvement in quality of supply. Government and various state regulatory bodies in India measures reliability supply indices such as SAIFI, SAIDI, CAIDI and monitor the interruptions on a regular basis, however there are no or only few

Conclusion The new technology associated with smart grid offers the opportunity to improve the quality and reliability as experienced by the customers. This new energy infrastructure shall be greener, dynamic, flexible, reliable, secure, and resilient. However, an issue of voltage quality regulation, especially in integrated, multi-function and multi-communication platform like smart grid is considerably high. Improving power quality for implementation of smart grids will require new developments from all stakeholders involved. If appropriate and immediate attention is not given, it may lead to financial losses, equipment damage, etc. The smart grid will be at the heart of tomorrow’s connected world underlining the ‘Quality’ of life for each one of us, hence conscious planning and implementation of the smart grid with attention to good power quality environment is the only way forward. In fact, total power quality will enhance the benefits of the users as well as nation in a great way by reducing the loading of the Grid with unwanted PQ issues. References 1.

On the sidelines of this event, Derek Hao, President, Huawei Technologies India and Ducky Tang, VP of Electric Industry – Enterprise Business Group, Huawei Technologies China speak to Subhajit Roy and outline the company’s roadmap for development of Indian power sector. Excerpts: Derek, could you briefly explain us about how ICT is transforming the power sector? Derek Hao: ICT, that was a supporting system even a few years back, has emerged as a production system in most of the industry verticals. Today no industry can realise its potential fully without optimising ICT system and are therefore witnessing digital transformations. The mission of Huawei Enterprises Business is to help our customer to realise the digital transformations. When it comes to making a smart city, ICT infrastructure is the backbone. ICT plays a key role even in smart energy management being the integral part of smart grid and Advanced Metering Infrastructure (AMI). Most of power sector utilities in India are grappling with huge AT&C losses. How ICT can play a role in this context? Derek Hao: The Indian government has introduced Restructured Accelerated Power Development and Reforms Programme (R-APDRP) and Integrated Power Development Scheme (IPDS) to ensure round

the clock power for all and reduce AT&C losses. The utilities are also developing AMI. ICT can play very important roles in all this initiatives by providing effective end-to-end communication solutions. Ducky Tang: We have developed the world’s first 100 megabyte professional broadband trunking solution based on enterprise LTE (eLTE) technology. Designed to address the evolution of trunking technology, Huawei’s eLTE technology meets the requirements for efficient operational communications in governments, railway systems, airports, ports, power grids, as well as oil and mining industries. In the power sector, eLTE can be used for automated meter reading in rural areas. Also, Huawei wide-band Power-Line Communication (PLC) solution is an effective tool as it significantly improves AMI communication quality across urban areas. Are you working in any power project in India? Derek Hao: Huawei is very focus on the power utility market in India since the past few years. We partner with India Smart Grid Forum (ISGF), a public private partnership initiative of Power Ministry set up for accelerated development of smart grid technologies in the Indian power sector.

ighting will play a significant role in the development of smart cities of the future as it pervades every area of an individual’s life–home, work, on the road and in public places. Moving beyond its functional role of illumination, connected LED lighting has the potential to enhance quality of life, transform everyday experiences and services, and ensure sustainability in our ever expanding global cities. Urban populations are growing rapidly and 60 per cent of the world populations are predicted to be living in cities by 2030 with more than 70 billion light points. “Philips Lighting is helping to pave the way for this massive urban growth by developing a people-centric blueprint for lighting and IoT services in the smart city of the future,” states Harshavardhan Chitale, Vice Chairman and Managing Director, Philips Lighting India. Philips Lighting India envisage there would be 4 key areas of direct application of connected lighting: Connected streets Connected LED street lights provide highly

Sustainable city farming Beneath the city and in unused spaces, urban farms that use little water and no pesticides, can grow plants and vegetables sustainably - reducing the distance between the farm and your fork, increasing food security, ensuring provenance and protecting precious natural resources. More personalised living Lighting will be able to synchronize with everything from your door bell to your television and music and will be fully adjustable to individual preferences. It will pre-empt your needs and complement your wellbeing, energize you, relax you and keep you safe. With the proliferation of network infrastructure be it Wi-Fi or cellular data in every business, houses, and public place, all buildings and public areas are destined to become smart. Internet of Things (IoT) is taking over across all domains and lighting is not an exception. Street lighting will no longer be an isolated sphere but part of a networked urban infrastructure. Informing on the role of lighting in making a smart city Shailesh Tokekar, General Manager & Head, Marketing and Retail Lighting, Wipro Consumer Care & Lighting says, “With smart and connected lighting solutions, LED luminaires Electrical & Power Review

can be connected to a network which further can be centrally controlled using software. This ‘smartification’ will enable illumination of various urban areas - city centers, main roads, residential streets, tunnels, parks, etc, precisely according to the lighting requirements in these areas. They enable demand-driven lighting, dimming the lights at off peak traffic hours leading optimum energy utilisation, reduce CO2 emissions, thus saving energy and reduce lowering municipal electricity costs.” In a smart city, street lights will fullfil many more functions than mere illumination. For example, they will notify the municipal corporations when the local garbage bins must be emptied, or record a change in traffic volume and communicate with the road traffic controller to diverge traffic accordingly. Street lighting posts can also serve as data stations with sensors, can monitor parking spaces and communicate information

about these, or recharge the batteries of an electric car. Being connected to a single network, the lighting system will have a concrete data on the amount of electricity consumed by each light on a broader level or even how much a phase consumes. This will help in eliminating the problem of electricity theft as the leaks in a particular network can be readily discovered and necessary actions can be taken. As cities grow, a security infrastructure of sensors and cameras will decrease the risk of any threat, accidental or intentional. Such a system can run directly over the centrally managed street lighting grid, making the city a better place to live in. Smart cities use recent advances in communications and digital technologies, data sharing, analysis and intelligent design to make cities more livable, resilient, economically sound, and sustainable. “Smart city lighting system changes the concept of management by using the lighting grids. Street lights are a vital part of every city, providing citizens and business with safety and security. Networked street lights are more than mere appliances for artificial lighting. They become nodes in a multi-functional network but what if we could use our street lighting network in a more intelligent way rather than the simple on-off system that currently exists.

Lighting industry as amongst the biggest and the most versatile industry in the world. The trend of market is from simple light to products suiting multiple requirements. Indian customers are more and more concerned about the efficiency of light. Customers are also keen on looking for system solutions and smart lighting, reveals Rhambo Zhang, India Head, Opple. The vision of smart cities differs for people living in diverse geographical locations. Some of the places are densely populated, whereas some have low infrastructure facilities. Sometimes even the disposition of the local government and private business of investing money to create smart-city initiatives may lack in several cities. “Keeping such factors in mind lighting plays a major role in shaping a smart city,” notes Zhang. Smart lighting includes smart sensors that can be found in several applications such as utility poles, water lines, buses, traffic lights, etc. “Most of the power consumed from these sensors comes from the wireless links used to transmit data. Thus these developers are working on creating unique and innovative lights which can turn this place into smart cities,” explains Zhnag. As per Mangesh Khisty, Sr. General Manager and Head, Marketing, Lum BU, Bajaj Electricals Ltd to reduce electrical demand, cities are adopting LED. LEDs have changed the way how we light the world, successfully displacing traditional illumination sources across every part of globe. This transition has kicked off a new phase of LED adoption – the race to connect every light point. According to Gautam Seth, Joint MD, HPL Electric & Power Ltd, the growing interest in intelligent and smart lighting is expected to change market dynamics with the announcement for the establishment of smart cities, which will increase demand for LED lighting, based on intelligent and connected infrastructure. Further, under the Make in India initiative, 100 per cent foreign investment under the automatic route has

Moreover, with government’s increased interest in converting existing street lights into LED is expected to increase demand for LEDs in coming years and the deteriorating power situation across the country and limited budget allocation for starting power projects have directed the government’s focus towards energy conservation and efficiency. Intelligent features of today’s lighting Lightings are available with intelligent features. Some of the experts will share the intelligent features in today’s lighting. The introduction of intelligent lighting offers several key benefits to a city. It allows constant monitoring of system status, obtain details of failures in real time, decide as to when, where and how much to switch on or dim, monitoring every unit from wherever one wishes. Basically the intelligent lighting system transforms lighting systems into a new territorial communications network and enables an intelligent support capable of activating a wide range of services to improve quality of life and make cities more intelligent, safe and sustainable. As per Kumbhat the major features are: • Energy efficient LED lighting system reduces carbon footprint and long term operation costs • Operational integration with real time data allows lighting control as and when required • Street disturbances and law and order system monitoring through noise detection, CCTV and community response • Traffic flow monitoring and data generation for city planning • Air pollution monitoring integrated into the lighting network • Extension of WiFI services through the street light network. “Accurate switching times based on local sunset and sunrise with the aid of photo-sensor or time-scheduled switches, increased flexibility of lighting, data management with the help of an energy consumption report, 24 hour online monitoring system (GIS), increased security with the help of anti-theft alarm are the title intelligent features of today’s lighting system,” states Tokekar.

Street light cloud-based control systems also offer individual luminaire level control as per the light, time of the day, and location based longitude and latitude. Remote controlled based operation facilitates ease of maintenance while real time energy metering and report generation help to analyse and decide optimum electricity usage. These systems are pre-programmed; as soon as an error occurs or the system detects an unusual pattern, it automatically alerts the staff. This creates a new level of transparency concerning maintenance of street lighting grid. In order to identify defective lights, the city will no longer be dependent upon nightly inspection trips and complaints from citizens. The system will reveal the status of the connected city lighting right at its hub. “Wipro Lighting’s smart and connected lighting solutions provide for energy savings with reduced carbon emissions,” claims Tokekar. In this age of smart connected lighting system, lighting can connect and interact seamlessly with a building’s Ethernet or wireless network, allowing remote monitoring and operation through a network of smart controls, devices as well as apps. Lights can be equipped with sensor nodes that are capable of conveying information like room occupancy, temperature and humidity, thus operating automatically basis the presence of people at a particular place. This has paved the way for a fully digitally lit world with connected LED lighting systems. “Our personal wireless lighting system – Philips Hue is one such example. It allows users to personalise and control home lighting using just their smartphone or tablet. Similarly, connected LED lighting at offices can significantly enhance the energy efficiency of a building by regulating facilities such as lighting, heating, cooling, and meeting room availability according to its occupancy levels,” says Chitale. As per Zhang there are several trends going on in the lighting industry these days, some are: Wireless control: These LED lights come in enough variants and with a USP of ‘No Wires’. Lights with ‘No Wires’ is the latest trend these days. Users can now control these smart lights via a tablet or a smart phone. Smart connectivity: Everything from applications to gadgets is well connected via internet in today’s world. The internet of

things is basically used to describe activities that are controlled especially by your computer or the smart phone. Lights that are controlled especially by the web are the new entrants in the industry. Inbuilt sources: LED lights come with irreplaceable light sources. LED light sources need not be replaced quite often. Manufacturers nowadays work on creating technologies that are inbuilt and that don’t require any lamps or moulds that can cover them. These are easily available and come in various sizes and styles. Khisty believes intelligent lighting is the new technology in which every company is trying their hands to make: Sensors control: Various sensors like motion sensors are used today in offices where light get automatically shut down when it is not required. Dimming: Dimming of luminaires is in its starting phase, where outdoor diming option based on live traffic is needs to be researched where Bajaj is working and doing research as streetlight consume hell lot of energy, and dimming them say in midnight when your traffic density is very low can save a lot for municipal corporation. M-M communication: Streetlights in the particular area form mesh network, where every streetlight talk to each other and remotely we can control the streetlight which includes default detection, life etc. Khisty believes that shift from analog to digital, low cost supporting technologies, ubiquitous install base are the three factors which has revolutionised the era of intelligent lighting. LED lighting is technology adoptions that have witnessed tremendous growth in recent years. LEDs are gaining more prominence as compared to CFLs, especially in urban regions of India on account of their affordability and awareness. Affordable cost of LEDs and the ease of availability of such technology make it a more attractive option. Further, unlike CFLs, LEDs do not contain harmful substances like mercury, making its end-of life disposal easy and environment-friendly. LED has higher brightness level than same wattage of other lighting technologies. It has longer burning hours, is more energy efficient due to dimmable feature, has higher power factor. “Intelligence comes while interfaced with sensors like microwave sensor, ambient light sensors, PIR sensors, occupancy sensor or astronomical clock. These sensors help in changing brightness level dynamically as required. We can say ‘Lit up when required’. Depending upon traffic movement/ambient light level, intelligent lights switches to higher brightness/low brightness or completely powered off. Remarkable amount of power can be saved. Significant savings in power allow intelligent LED based lights to be clubbed with solar solutions also. Intelligent Continued to 46

Some of the major aspects of smart cities are transportation, recycling of waste, proper HVAC systems, clean environment uninterrupted power supply and much more. As power is one of the major components of the smart cities one cannot think of smart cities without power supply. Smart cities require clean and continuous supply of power and for this there is a need to develop alternative energy sources to make the cities financially and ecologically viable. The power sector in the country is developing rapidly and the government is promoting various energy sources such as wind, solar, hydro, and nuclear – and is also introducing new technologies to harness power from renewable energy and use to generate power and to supply uninterrupted power to the new development taking place in the country like smart cities. Though there are developments taking place but is India’s renewable sector prepared to take up the smart cities challenge? Is renewable energy sector ready to take on smart city challenges? India is witnessing unparalleled transformation from rural to predominantly urban living over the last two decades. It is expected that the smart cities will include a large number of infrastructure services and smart solutions. “In particular, the elements that must form part of a smart city are assured electricity supply with at least 10 per cent of the smart city’s energy requirement coming from solar and smart metering. In order to make smart cities a reality and to propel India into the future India needs sustainable, reliable and uninterrupted power supply,” says Rahul Shah, Chief Executive Officer, Tata Power Renewable Energy Ltd. Developing India’s capability in the new and renewable energy space is a key requirement to ensure success of the smart cities project.

India has immense potential in this area and many efforts have already been initiated by the government for the development of solar energy. The government is promoting renewable power in a big way. The target of generating 20 GW through solar power has been enhanced to five times at 100 GW by 2022. The total installed capacity crossed the 5 GW mark recently and there is a clear line of sight to get to 20 GW in the next 18 months, which is commendable. India’s challenges with harnessing renewable energy are unique. For example, accumulation of dust on solar panels and high per unit cost of energy are some of the challenges the renewable energy industry in India faces. Therefore it is important to increase and incentivise focus on developing indigenous technology and indigenous solutions. “With the announcement of smart cities, the smart grid technologies are expected to gain importance. The smart metering will be the first step towards this cause. However, these technologies need huge investment and the industry does not have the financial capacity to fund for the technologies,” observes Shah. “It has already been mandated that 10 per cent of the smart cities energy requirement will come from solar energy and at least 80 per cent buildings should be energy efficient and green buildings. With a plan to develop approximately 100 such cities, the rate of renewable energy usage will go up in the country,” comments Kanav Sachdev, Brand Manager, Su-Kam.

Tata Power has already achieved proof of concept by installing a floating solar power plant sized plant on its lake in Lonavala.

Kanav Sachdev, Brand Manager, Su-Kam

While speaking about how India’s renewable energy sector ready to take on smart city challenges Sachdev says, “The challenge in implementation is the area required for solar modules installation as mostly the smart cities will be dominated by high rise buildings with very less space on roof.” A typical 3 bhk apartment have a roof space of 2000 sq. ft. which is roughly about 20 KW of solar power. On the brighter side, this could mean that the builders and architects may opt for solar to power the apartment complexes to provide the house owners with 24x7 electricity. So building can be designed in such a way that it support solar. Central and state government plans to develop 109 smart cities in India. Under the mandate of the smart cities, 10 per cent of the city’s energy requirement must be met by solar. Most of the local generation would take place via rooftop solar power plants. Government aims to install 40 GW of solar rooftop under the national solar mission by the year 2022 and as of now only 1 GW of solar has been installed. “Discoms are still not comfortable with solar rooftop installations and it will take some time for them to get used to the concept of net metering. Solar installations in smart cities would only succeed if both Discoms encourage distributed generation and customers are made aware about the benefits of rooftop solar,” emphasises Kuldeep Jain, COO EPC Projects, Vikram Solar. “In addition to these, renewable energy may be used to power electrical vehicle under the National Mobility Mission which would require multiple charging points across the cities. Developing this charging station infrastructure which runs on solar would also be crucial,” adds Jain. The objective of the smart city mission is to promote cities that provide core infrastructure and give a decent quality of life to its citizens, a clean and sustainable environment and application of

smart solutions. Therefore, the focus is on sustainable development and inclusive growth. Providing clean and smart energy solutions is the key to achieve the objective. “With the current state of renewable energy sector, we believe it is ready to serve smart cities customised for its purpose e.g renewable energy solutions integrated with storage solutions based on micro/mini-grid platform can serve the requirement of clean energy with very efficient Demand Side Management (DSM),” states Manoj Kumar Upadhyay, Founder and Chairman, ACME Group. The current urban population is 1.5 billion and over a period of time, this can reach up to 60 per cent of total population contributing 75 per cent of GDP. In this context, making the city smart is both necessary and challenging. The concept of smart cities revolves around smart energy, smart transport, smart water and waste management, maximisation of e-governance services and smart buildings.

We look forward to establishing a relationship with CEO’s of the Special Purpose Vehicle, which would be responsible for monitoring the progress of smart cities.

Kuldeep Jain,COO EPC Projects, Vikram Solar

Renewable Energy Sources (RES) used in small-scale distributed generation systems are a promising alternative for additional energy supply toward smarter and more sustainable cities, believes Ketan Mehta, CEO, Rays Power Infra. He adds, “However, their proper integration as new infrastructures of the smart city requires understanding the smart city architecture and promoting changes to the existing regulation, business models, and power grid topology and operation. A step towards smart grid formation and recent advancement of technology in renewable makes it compatible to take smart grid challenges.” Solar power generation is better than any other source of energy believes Ashish Joshi, MD and CEO, Addin Power Ltd. He says, “India’s renewable energy sector is ready to take on the smart city challenges because there is lots of sun radiation as well a perfect atmosphere for 30 years power generation. Government is also supportive for solar different kind of promotional scheme. Solar is durable, maintenance free, green clean and environment friendly energy which is far better than any other renewable energy source.” Are the players ready to take up this challenge? ACME is major player in giving India many innovative solutions in energy conservation, energy management, energy generation, energy storage and hybrid solutions. “In alternate energy sector, with an existing portfolio of over 1.5 GW solar PV power projects, ACME is committed to setting up January 2017

Rays Power Infra’s R&D team keeps on working for the advancement of technology so that it can develop eco-friendly society and achieve sustainable growth. Su-Kam has always supported the government in its initiatives for solarising India and will continue to do so in making of smart cities. It has a big range of household solar products that are easy on the pocket and simple to install. Su-Kam has developed smart solar inverter which can be integrated with smart phone for operation and monitoring purpose. It is also working on hybrid technologies which can charge the batteries in the daylight and supply excess electricity back to the grid and in the evening, time the load can be run through battery. Also, it can smartly manage the load according to availability of solar power. For storage of solar power in a compact area the company is doing R&D on lithium ion batteries inspired by Tesla Power wall. Tata Power Renewable Energy Ltd (TPREL) has reiterated its commitment to clean energy by increasing the share of non-fossil fuel energy to 30-40 per cent by 2025, up from its earlier target of 25 per cent. This move is in line with the government’s set target of 100 GW from solar and 60,000 MW from wind. TPREL recently acquired Welspun’s renewable portfolio of 1,140 MW along with a 30 MW solar project in Maharashtra, and 100 MW solar in Karnataka under National Solar Mission. Every year, Tata Power strives to add about 150 MW of wind, and 30-50 MW of solar, depending on the market opportunities.

As the conventional grid connected and rooftop solar projects continues at its own pace, sector need to look at various innovative technologies to achieve the target for 100 GW of solar. “Tata Power has already achieved proof of concept by installing a floating solar power plant sized plant on its lake in Lonavala,” informs Shah. Vikram Solar expects that around 25-30 GW of solar installations may be required in smart cities across India to meet the 10 per cent of the smart cities energy requirement. Installing such capacity in these cities from the present 1GW in next 6 years may be an ambitious task where both central and state government will have to work closely. The company expect that with continuous decrease in solar module prices, the awareness about solar rooftop will increase and customers may start exploring the option of generating electricity at their rooftop. Vikram Solar is actively looking at the market for smart cities being developed and helping the government achieve the 10 per cent target. “In addition to solar rooftop installations, we also look forward to tapping new opportunities like distributed energy generation in the smart cities. We look forward to establishing a relationship with CEO’s of the Special Purpose Vehicle, which would be responsible for monitoring the progress of smart cities. With the necessary experience and expertise, we are ready to make smart city development a success,” says Jain. The demand for energy is rising with the rapidly increasing Indian population. Moreover, most of the rural belts of India have inadequate, minimal or no electricity, which is a vital ingredient in the development of any community. Addin is focusing on solar energy, one of the best options in green solar renewable energy, to provide sustainable and economical power supply to rural India.

The network is the asset

The world’s largest private-sector energy services company uses FLIR Systems thermal cameras to inspect and maintain its network in Bavaria, Germany.

T

he network is the energy supplier’s most valuable asset. And this asset has to be maintained. Not only to prevent blackouts to its private and corporate customers, but also to ensure a long-term leading position in a market which has gained momentum and scale after the European Union-wide deregulation and liberalisation of energy and power supply. E.ON is a power and gas utility company of German origin, and with its entire stakes combined, the world’s largest private-sector energy services company. With annual sales of EUR 49 billion and around 70,000 employees worldwide, E.ON has strong positions in Central, Northern Europe and the US Midwest region. E.ON Bayern, headquartered in Regensburg, Bavaria, is a daughter of E.ON Energie, the main power supplier in Central Europe. E.ON Bayern employs around 3,700 people and invests some 200 million Euros per year in its power network.

Thermography contributes to preserving and maintaining regional electricity network

“Thermography is not a new issue at E.ON Bayern,” says Measurement Engineer Uwe Thomas. “When, some 15 years ago, infrared cameras became handy and affordable, the local IsarAmperwerke supplier started to use infrared cameras from Agema for inspection purposes.” Agema later became FLIR Systems. The plausibility of thermography has been thoroughly questioned in the wake of the deregulation and subsequent

major restructuring at the companies which eventually merged into the Central-European stronghold E.ON Energie. But the conclusion reached has turned out to be positive: thermography was acknowledged as a vital non-contact inspection method. E.ON Bayern’s thermographers are hence solidly integrated into the E.ON Bayern Messtechnik (Measurement Engineering) department. Inspections

Thermography’s task at E.ON Bayern sounds easy: inspection of infrastructure that generates, transmits and distributes electrical power on a middle and low voltage level. The numbers are impressive: 50,000 square km of territory covering three-quarters of the largest German federal state. A 175,000 km long low- and middle voltage network roughly from the outskirts of Frankfurt to the Austrian Alps. A dazzling total of 43,000 objects - transformers, substations, switchgear, terminal blocks, distributors, have to be inspected at a rate of a couple of thousand per year. How do they cope with such figures? A team of eight thermographers, manned with ThermaCAM P60 and P65 cameras respectively, “all qualified and weathered

electricians,” as Thomas likes to point out, inspect all installations everywhere, including switchgear in remote Alpine areas. These thermographers are specialists in using the infrared camera outdoors. They are acquainted to its typical pitfalls such as the distorting effects of reflection, wind speed, and the effect of weather conditions on the measurements. Regarding emissivity levels, E. ON Bayern’s thermographers use the standard settings as provided in the camera’s menu, while adapting them for some specific measurements. The inspection cycles at E.ON Bayern are adapted to the role, type and location of the switchgear. There is inspection cycles every 5, 9, and 12 years. However, installations near busy traffic intersections or dusty industrial environments, which can be affected by pollution such as salt, dust, smoke or soot, are inspected at least once a year, generally in spring.

Otto Heigl, thermographic inspector at E.ON Bayern, demonstrates the use of the FLIR thermal imaging camera.

intensively”, says thermographer Helmut Holzapfel. “Its visual camera and detachable LCD screen are a big asset and absolutely indispensable. And, there is another important rule to carrying out our inspections: care comes before speed – as we have large inspection cycles, we inspect our objects very carefully”, he adds. From a collaborative, assisting position within the power supply network maintenance, thermal cameras at E.ON Bayern have grown into a strategically important inspection and reporting tool. Drawing on a consistent long-term measurement policy and the expertise of the camera operators, thermography has established itself as a technique able to support the change process from a monopolising power supplier to an energy provider caring about its main assets.

In addition, the thermography team keeps a 24/7 stand-by service which essentially provides documentation prior to or after reparation works at transformers. “We can be called up at anytime for an urgent inspection by an inspector or a technician, who does not like the sound of the transformer in his substation,” says Holzapfel. Result management

The inspection reports are filed into FLIR System’s Reporter Pro software. The data are fed into a predictive maintenance module of the German enterprise application integration software giant SAP. The images are kept separately in a database based on FLIR Systems Reporter software. To organise its maintenance priorities, E.ON Bayern has defined three levels of urgency to maintain its low and middle voltage installations: L1 stipulates a repair at the next inspection, L2 requires reparation within 6 months, while the L3 level urges repair within one working week. The FLIR Systems cameras used by E.ON Bayern’s thermographers contribute to managing the workload: “We use all major features of the ThermaCAM P65 and P60 Electrical & Power Review

T

he motion plastics specialist igus has expanded its range of multi-axis energy chains and introduces a new size for the lightweight triflex TRLF. “With 125 millimetres diameter, this is the largest in the range and can safely guide even more cables and hoses,” the company claims. “The e-chain for torsional movements is impressive with very fast assembly and disassembly, which significantly reduces shut-downs. For this reason, it is extremely popular with robot manufacturers and users.” Industrial robots have become indispensable in production today, as they save a lot of labour and time. In order to achieve this in the equipment on the robot itself, the motion plastics specialist igus has developed the multi-axis triflex TRLF energy chains, which are now available in a new size. The ‘L’ in the product name stands for ‘light’ because material is saved through the open design of the individual links, but at the same time the cables and hoses are still guided safely. The ‘F’ stands for ‘flip open’ and describes the mechanism very well: “Each single chain link has three pivotable cross bars that can be opened up at any time by hand or wiith a screwdriver,” explains Harald Nehring, authorised agent for e-chainsystems at igus. “This allows the filling with big cable diameters or hose packages.” With the new size TRLF.125 with a nominal diameter of 125 millimetres, even large and/

or stiff hoses or a large number of individual cables can be inserted quickly and easily.

Quickly assembled, safely guided By dispensing with continuous support elements like steel cables or spring elements, the assembly and disassembly of triflex TRLF is as easy as the filling. The chain can be extended any time by snapping on new links using the ball-and-socket joints. The chain can be shortened easily by hand, simply by rotating the chain links with little force. In this way the triflex TRLF is strong enough to simultaneously guide various cables for energy, data and media. By the 3 way interior separation, defined minimum bending radius and torsion of about (+/-) 200 degrees per metre of chain, a reliable guidance is ensured and damage to the cables and hoses is prevented.

Transform the potential of your transformer reference materials for posterity. A more effective solution is to build a library and have your in-house experts curate the collection. Annotating key materials as they relate specifically to the company is another invaluable service these employees can provide – and most of them will be glad to do it as they are passionate about their profession! • Grow: Materials are all around but they need to be sourced, thoughtfully selected and catalogued, so make sure you have someone who is knowledgeable enough to do that for the library. • Maintain: While some material may be timeless, the most recent understanding of a subject must also be housed within the library. Electrical testing, for example, has advanced – if you have material on this topic, when was the last time you updated it?

To aid in the organisation of a corporate or personal library, Megger is introducing a comprehensive series of Transformer Life Management bulletins that broadly cover the fundamentals of managing the life of a transformer.

T

hroughout their working lives, most engineers amass a collection of invaluable reference material. And it is safe to assume that most will have also dealt with the angst of having misplaced a valued piece of reference at some point! Such occurrences fuel subsequent reluctance to loosen a tight grip on these resource libraries. Since, in most cases significant personal investment has been put into growing these collections – which typically include university textbooks and the like – often, when valued employees move on, these treasure troves follow them. This highlights the advantages of establishing and maintaining a protected corporate library, accessible to all. A corporate library serves important roles, such as spreading valued knowledge much further within the organisation. It also helps with succession planning, as an additional way to pass on knowledge. This is what you can do as a company to retain this wealth of information: • Build: While most companies have employees who know a lot, it is unlikely that they have time to write it all down

Introducing Megger Transformer Life Management (TLM) Bulletins To help with the building, growth, maintenance and organisation of a library (be it corporate or personal), Megger is introducing a comprehensive series of Transformer Life Management (TLM) bulletins that deal with the fundamentals of managing transformers throughout their working lives. The bulletins cover topics such as moisture in transformers as well as detailing the many electrical tests available to assess transformer condition. Continued to 64
