   Solar Frontier and Welspun Renewables signs 100 MW solar module supply agreement
   
   Solar Frontier and Welspun Renewables announced the signing of a 100 MW solar module supply agreement. Solar Frontier will supply its proprietary CIS thin-film solar modules, manufactured in Japan, to Welspun Renewables, a leading generator of solar energy in India. Solar Frontier’s CIS modules will be used in Welspun Renewables’ upcoming solar power projects in India at sites with high levels of solar irradiation.
   
   Mr Sindoor Mittal, Director of Welspun Renewables, said that “Solar energy is a priority sector for meeting India’s high demand for clean, renewable and economical energy. The government of India has set a target of 175 GW of renewable energy by 2022, of which 100 GW will be solar energy. Agreement with Solar Frontier brings us one step closer to meeting our green energy commitment.”
   
   Mr Mittal said that “Welspun Renewables is committed to achieving high level quality benchmarks at all of its project sites, and because of this we prefer to work with Tier1 technology providers. We have worked with Solar Frontier on multiple projects before and we do so again based on the proven high electricity yield and quality of its CIS technology, on top of the company’s close support.”
   
   Welspun Renewables’ supply agreement follows a recent spate of Power Purchase Agreements that the company has signed with multiple state governments. The company targets commissioning over 1 GW of solar and wind capacity within fiscal 2015. Welspun Renewables is present across nearly all states in India.
   
   Mr Atsuhiko Hirano, CEO of Solar Frontier, said that “We are honoured to continue working with Welspun Renewables on its mission to help India meet its growing energy requirements in an efficient, environmentally-friendly manner. This is a landmark agreement for Solar Frontier as we continue to develop our presence in key international markets with companies that are sustainable and show willingness to work closely together.”
   
   CIS modules generate a higher energy yield than crystalline silicon modules in real-world operating conditions. This includes hot climates such as in India, where CIS modules benefit from a low temperature co-efficient and their 'light-soaking effect,' which further boosts power output after the module is exposed to light.
   
   Solar Frontier is the world’s largest provider of CIS solar energy solutions by shipments and revenue.
   
   Manufacturing at GW-scale capacity from the southern Japanese prefecture of Miyazaki, its advanced production process has enabled it to achieve the highest level of mass production thin-film efficiencies at world-class production costs. In 2015, Solar Frontier is re-engaging the global market, from the Americas to Europe, South and Southeast Asia.

   Total Solar Eclipse “Blacks Out” Europe
   
   03/20/2015 | Sonal Patel
   
   Several gigawatts of solar energy faded from European grids during the two-hour solar eclipse that shadowed the continent, as well as parts of Northern Africa and Asia, on Friday morning.
   
   But according to the European Network of Transmission System Operators for Electricity (ENTSO-E)—an organization representing 41 transmission system operators (TSOs) from 34 European countries—grid operators successfully managed the fast variations in solar generation.
   
   “The European power system needs to be balanced every single second. Between 9.00 and 12.00, Brussels time, TSOs had to reinforce their cooperation to cover the unusually fast loss followed by even faster reintegration of some 17 GW of solar generation,” it said.
   
   ENTSO-E said preparations to ensure reliability during the eclipse had been underway for several months. Distribution System Operators and generators notably responded to the call for proactive cooperation.
   
   The group’s Solar Eclipse Impact Analysis called the event an “unprecedented challenge” for European TSOs. “Solar eclipses have happened before but with the increase of installed photovoltaic energy generation, the risk of an incident could be serious without appropriate countermeasures,” it noted.
   
   “What makes this year’s solar eclipse so special is the fact that there is now a non-negligible amount of energy generation units connected to the grid that are highly sensitive to variations in solar radiation,” said ENTSO-E. One reason this event posed such a concern is that the event occurred in the middle of the morning. “It’s like having two sunrises and two sunsets in the same day.”
   
   However, TSOs managed to forecast with “a lot of precision the effect of the eclipse on solar generation; taking even into account the ‘worst case scenario’ that the eclipse would take place on a sunny day. The sun was indeed shining this morning in Southern Germany and Northern Italy where the concentration of photovoltaics is the greatest of all the ENTSO-E area. The most critical moment was between 10:45 and 11:15 when the solar generation started to go up again,” it said.
   
   Over the last decade, the amount of photovoltaic (PV) generation has dramatically increased. In 2002, solar power made up a 0.1% share of all electricity produced by renewable sources; by 2012, that figure had risen to 10.5% of renewables. Solar power supplies 3% of continental Europe’s total electricity consumption today, according to ENTSO-E.
   
   ENTSO-E had prepared to inform the public of national incidents occurring on power systems during the event. It had also warned PV generators that injection would depend on weather conditions, which were uncertain.
   
   Each TSO made its own preparations, meanwhile. German transmission system operators, for example, secured additional secondary reserve that could be activated within a 5 minute time period ahead of the eclipse. Operators estimated that the country, which now depends on solar power for about 7% of its generation needs, needed additional control reserve capacity amounting to 2,279 MW of “negative” secondary control reserve and 2,246 MW of “positive” secondary control reserve.
   
   According to ENTSO-E, solar generation on Friday morning was exceeding the normal seasonal level, as a result of “very sunny weather.”
   
   “But despite this challenge, German TSOs managed very smoothly the high and fast variations of 39 GW of installed solar generation relying on power reserves at national and regional level,” said the group.
   
   “In view of the sunny weather forecast, Italy had decided in cooperation with DSOs and generators to take an equivalent of 5 GW PV out of the system, between 7:00 a.m. and 2:00 p.m. today. Thus, PV from 13 GW rather than 18 was in the system during this period. After 2:00 pm reconnection will start for the full capacity.”
   
   The European grid had resumed normal operations by noon after the solar eclipse was over.

   PwC to formulate a plan to scale-up solar energy capacity in India
   
   Clean Technica reported that nearly a month after announcing the grid-connected solar capacity scale up plan from 22 GW to 100 GW by 2022, the Indian government has announced that one of the leading professional services network companies, PricewaterhouseCoopers, has been hired to formulate a plan to scale-up solar energy capacity in India.
   
   PricewaterhouseCoopers role will be to assess the country's power scenario and demand, review the current solar energy policies of Ministry of New and Renewable Energy, and determine a realistic power demand projection along with a solar energy scale-up to meet the future power demand.
   
   In addition to assessing the power scenario of the country, PwC will also evaluate the possibility of attaining grid parity and assess the robustness of the current power evacuation system to meet the government's ambitious plan of 100 GW of solar capacity by 2022. PwC will take into account views of the relevant stakeholders for formulation of the scale-up plan to meet the country's solar energy target.
   
   Currently, growth in the solar power sector can be associated with various promotional policies both at the national and state levels. The National Solar Mission has been driving solar installations within the country since its launch in 2009. The current installed solar power capacity stands at around 3 GW, or about a tenth of the total renewable energy capacity and just over 1% of the total power capacity of the country. If India achieves the 100 GW installed capacity by 2022, solar power would contribute about 25% to the total power installed capacity.
   
   With a targeted installed solar power capacity of 100 GW by 2022, India will have to add 12 GW capacity every year, which appears to be very challenging.

   Study: Perovskite-Silicon Tandems Provide Big Boost to Solar Efficiency
   
   Stacking perovskites, a crystalline material, onto a conventional silicon solar cell may dramatically improve the overall efficiency of the cell, scientists from Stanford University concluded in a new study.
   
   “Right now, silicon solar cells dominate the world market, but the power conversion efficiency of silicon photovoltaics has been stuck at 25% for 15 years,” explained Professor Michael McGehee, who co-authored the study recently published in the journal Energy & Environmental Science. One cost-effective way to improve efficiency is to build a tandem device made of silicon and another inexpensive photovoltaic material, he said, but “until recently, we didn’t have a good material for the top cell. Then perovskites came along.”
   
   Perovskites are synthetic crystalline materials with the same crystal structure as the mineral perovskite. They are inexpensive and easy to produce in the lab. In 2009, scientists showed that perovskites made of lead, iodide, and methylammonium could convert sunlight into electricity with an efficiency of 3.8%. Since then, researchers have achieved perovskite efficiencies above 20%, rivaling commercially available silicon solar cells. The advancements have piqued the interest of silicon manufacturers worldwide.
   
   The tandem solar cells work by converting photons of sunlight into an electric current that moves between two electrodes. Silicon solar cells generate electricity by absorbing photons of visible and infrared light, while perovskite cells harvest only the visible part of the solar spectrum, where the photons have more energy.
   
   “Absorbing the high-energy part of the spectrum allows perovskite solar cells to generate more power per photon of visible light than silicon cells,” said Stanford graduate student Colin Bailie, co-lead author of the study.
   
   One hurdle to building an efficient perovskite-silicon tandem has been a lack of transparency. Also, perovskites are easily damaged by heat and readily dissolve in water. So the team used a sheet of plastic with silver nanowires on it and built a tool that uses gentle pressure to transfer the nanowires onto the perovskite cell (Figure 4). When the team stacked a perovskite solar cell with an efficiency of 12.7% on top of a low-quality silicon cell with an efficiency of just 11.4%, the results were impressive. “We improved the 11.4% silicon cell to 17% as a tandem, a remarkable relative efficiency increase of nearly 50%,” McGehee said.
   
   In another experiment, the research team replaced the silicon solar cell with a cell made of copper indium gallium diselenide (CIGS). The researchers stacked a 12.7% efficiency perovskite cell onto a CIGS cell with 17% efficiency. The resulting tandem achieved an overall conversion efficiency of 18.6%.
   
   The team is now working on resolving the “unanswered question” of how perovskites fare in terms of long-term stability. “You can heat [silicon] to about 600 degrees Fahrenheit, shine light on it for 25 years, and nothing will happen. But if you expose perovskite to water or light, it likely will degrade. We have a ways to go to show that perovskite solar cells are stable enough to last 25 years,” McGehee said.

   TATA Power Solar commissions 1.25 MW project at SASTRA University
   
   TATA Power Solar said that it has commissioned 1.25 MW rooftop projects at SASTRA University's Thanjavur and Kumbakonam campuses in Tamil Nadu.
   
   SASTRA has inked a pact with TATA Power Trading Company under which the latter will sell electricity generated from the facilities to the university for 15 years, the private solar firm said in a release here.
   
   Commissioned as a part of the university’s green energy efforts, the plants are likely to offset 30% of its total power consumption.
   
   The company said that these plants will generate nearly 20 lakh units of power annually and reduce more than 1,600 tonne of carbon dioxide emission.
   
   Set up on 11 buildings across the 2 campuses, these plants come with in built grid interactive string inverters to achieve efficiency up to 98% and reduce losses.
   
   To further minimise transmission and distribution losses, power generated by each rooftop plant will be used by the same building.

   Trina Solar sells its third solar power project in the UK
   
   Clean Technica reported that Trina Solar has offloaded its 3rd solar power project in the UK in-line with its strategy to develop and sell power assets.
   
   The China-based solar power giant sold the 49.99 MW solar photovoltaic power plant located in Norfolk. The project has been acquired by Bluefield Solar Income Fund for USD 87.7 million. BSIF will provide a bridge loan which will be used by Trina Solar to finance the project once the sale is completed.
   
   With this sale Trina Solar has developed and sold three large-scale solar power projects with cumulative capacity of 73.76 MW. The Norfolk project was commissioned in Q3 2014 and was connected to the grid earlier this year making it eligible for a higher renewable obligation certificate multiplier of 1.4.
   
   Bluefield Solar Income Fund Limited make equity and debt investments in renewable energy assets. The company has led acquisitions of and currently advises on over 50 renewable energy assets. It currently has stakes in at least 15 solar PV projects with a cumulative capacity of over 160 MW.
   
   Trina Solar may sell solar power assets in similar deals in the near future as the company plans to install 700 MW to 750 MW capacity this year.

   Solar power plant with 100MW capacity planned for Northern Emirates
   
   The National reported that solar power plants with a combined capacity of 100 MWs are being planned for the Northern Emirates in a Dh500 million project that aims to cut the cost of energy production and lower carbon emissions.
   
   Mr Mohammed Saleh, DGl of the Federal Electricity and Water Authority, said the state news agency Wam that the plants will be built in partnership with the private sector. Work on the first plant will start this year.
   
   A plant with a capacity of 100 MW can produce enough power to meet the needs of 20,000 homes. In terms of carbon emissions savings, this equals about 175,000 tonne of carbon dioxide per year, the equivalent of removing 15,000 cars from the roads.
   
   According to the strategy, Fewa's decision follows the Vision 2021 strategy which has set a clean energy target. By 2021, 24% of the country’s power should come from renewable sources or nuclear energy.
   
   In 2013, only 0.02% of energy in the country came from such sources.
   
   Further details of the Northern Emirates project are yet to emerge but the announcement was welcomed by solar industry observers.
   
   Mr Claudio Palmieri, technical director of the Clean Energy Business Council and CEO of CLS Energy Consultants, said that “The decision is a clear indication that the UAE Government is serious about achieving its renewable energy targets and dedicated to protecting the environment.”
   
   Mr Sami Khoreibi, CEO and founding partner of solar power installer Enviromena Power Systems, said that it remained to be seen how the plans would be implemented, but he welcomed the move.
   
   Mr Khoreibi said that “My guess is, it would be that a lot of the solar capacity will be displacing diesel and oil generation capacity.”
   
   He explained that should this be the case, some solar technologies were definitely at grid parity with conventional resources. Mr Khoreibi expected the technology involved to be solar photovoltaic panels that capture the sun’s light and transform it into electricity.
   
   He said that the technology is no longer just a green option but an economically sound one, too.
   
   He added that “It would definitely make sense for it to be solar PV technology. PV is producing at substantially lower costs than other sources.”

   Kapchagay solar plant in Kazakhstan boosts its electricity generation
   
   The country's Samruk-Energo company said that Kapchagay solar power plant in Kazakhstan is increasing its electricity generation.
   
   According to Samruk-Energo, Kapchagay solar plant with the capacity of 2 MW was commissioned in December 2013.
   
   The volume of commercial electricity generation at the plant stood at 442,000 KWh in 2014.
   
   During the Q1 of 2015, 630 KWh of electricity, generated at Kapchagay plant was sold to consumers.
   
   Kapchagay solar plant started selling electricity to the settlement and financial center for supporting renewable energy sources from October 9th 2014.
   
   Under the law of Kazakhstan, the center carries out the centralized sale and purchase of electricity produced by the facilities by using renewable energy sources.
   
   Samruk-Energo company said that the state provides guarantees for the producers of 'clean' electricity in Kazakhstan for connection to the network, long-term agreements on purchasing of the whole produced electricity, as well as a guarantee for the purchase of the produced electricity at the fixed price.
   
   Kapchagay solar power plant was the first industrial project of the 'green' power engineering implemented by Samruk-Energo.
   
   Alongside with rich hydrocarbon reserve, 60% of Kazakhstan's territory has the potential to use solar, wind and water energy.

    Vanaf 26 maart, als het weer goed is gaat Voda ook SOLAR!
    
    Dan worden er 10 260Wp panelen van het merk BYD geplaatst op het platte dak, hier in Den Haag. Geschatte opbrengst per jaar tussen de 2200-2300 Kw. De hele installatie, panelen, roestvrijstalen rekken, bijna 1000 kg ballast!, extra elektra groep, kabels, pc informatie en omvormer, kost slechts 3000 netto (de BTW is terug te vragen).
    
    De opbrengst is nagenoeg gelijk aan mijn huidige verbruik. Na saldering van vaste lasten zo als Netbeheer, meterhuur etc., moet ik na verrekening van de energie heffing, zelfs geld terugkrijgen!
    
    Hoe dan ook, de terugverdientijd is ongeveer 6 jaar! Daarna is het dik extra inkomsten. Levensduur minimaal 25 jaar. Verlies rendement in die 25 jaar is volgens opgave < 15 %. 12 jaar garantie op alle onderdelen.
    
    Als SOLAR fan heb ik hier lang op gewacht, maar nu is ook de tijd op te investeren. Iemand die ik ken heeft deze panelen ook, en ze doen wat het belooft, flink opbrengen!
    
    Ik hou jullie op de hoogte van de ontwikkelingen.
    
    Oh, ik heb nog zo'n fijne energie meter met draaischijf (dubbel telwerk), die heerlijk terug kan draaien. Van mijn leven komt er geen "slimme" meter in mijn huis!!
    
    

    Installatie is uiteindelijk op vrijdag 27 maart geplaatst. De eerste 3 dagen tel ik even niet mee.
    Opbrengst na de eerste volle week (van maandag 30 maart tm maandag 6 april) was maar liefst 65 Kw. Dit was meer dan mijn verbruik over de hele week. Beide telwerken liepen dan ook netjes terug. De 1e paasdag zondag was een top dag, bijna 15 Kw die dag. De zon scheen dan ook bijna de hele dag. Dit gaat helemaal de goede kant op. De panelen leveren ook stroom bij grauw weer, zelfs toen het regende. Niet veel, maar toch een paar honderd watt per uur.
    
    Tot later.

    Right on time voda, happy solar days are here to come. April, mei, dan begint het serieuze zonnewerk want buitentemp. nog niet te hoog en een gunstigere instraling dan in volle zomer. Bij een dubbeltariefmeter loop je ook nog eens lekker op te wekken in de dure uren. Als je het een beetje kan uitkienen dan reken je straks enkel af in het lage tarief.
    
    You're hooked...

    Ha, Hosternokke, leuk dat je zo snel reageert. Yes, I'm hooked! :-)
    
    Hoe de afrekening zal verlopen heb ik nog geen flauw idee van. Toevallig loopt mijn verbruiksjaar nu van 28 december 2014 tm 31 december 2015.
    Die eerste 3 maanden verbruik zal ik wellicht niet helemaal "goed" kunnen maken. Sinds de installatie van de dubbelmeter in 1990, toen ik het huis kocht, heb ik altijd meer stroom verbruikt in het lage tarief, dan in het hoge tarief. Het verschil in tarief is ook niet zo groot meer dan vroeger. Ik ben nu bij Delta (de goedkoopste aanbieder vorig jaar) 22.7 cent hoog tarief kwijt en 20.84 cent laag tarief. Ik houd de (zonne)meterstanden ook apart bij. Moet nog wel kwijt dat ik aan de kust woon.
    Wat ik gelezen heb, schijn je hier meer zonneuren te hebben dan in het oosten, of zuiden van het land. (invloed van bewolking).
    
    Wat voor een systeem heb jij, en hoelang? Wat voor opbrengst?
    
    Bij voorbaat dank voor je antwoorden.

    Hallo voda, ik zag toevallig je update, vandaar de snelle reactie eerder vanavond.
    Zit als Zeeuw natuurlijk ook bij Delta. Ik woon enkele 100-en meters van de kust. De gehele NL-kust komt er gunstig uit qua opbrengst.
    Heb in 2011 meegedaan aan de 1e actie van Wij willen zon (Urgenda) die destijds zonder gedoe met moeilijke subsidieregelingen gewoon een goede korting konden bedingen bij de leverancier (in mijn geval 12 x Csun, totaal 2760 wp, opbrengst rond de 2700 kWh)). Eenmaal geïnstalleerd zie je de meter achteruit draaien et voila >>> you're hooked. En dan volgt de jacht naar meer kWh-en om te besparen. Al met al ben ik van zo'n 5000 kWh/jr naar 340 kWh afgelopen jaar gegaan. In geld uitgedrukt van €998,- naar €67,-. Ik was uitgegaan van een terugverdientijd van 10 jaar, dit wordt nu ca 6 jaar, easy. Ook ben ik mijn gasverbruik gaan monitoren dus die terugdraaiende meter heeft een behoorlijk effect. Het is vooral het beperken van onnodig verlies in je energieverbruik waar veel winst valt te behalen. Als bonus verhoog je je comfort als je de juiste maatregelen treft. Ook nog.
    In beleggingstermen uitgedrukt was het beter geweest om eerst een setje van 3 aan te schaffen als grote teen in het water. Hierna had ik direct enkele stop losses kunnen plegen om van hieruit de juiste vervolgaankopen te kunnen doen. Maar ja, als je alles van te voren weet heeft verder leven ook geen zin meer.

    Maar uiteindelijk gaan we allemaal zelfvoorzienend worden. Dit duurt misschien niet al te lang meer...

    Right on time voda, happy solar days are here to come. April, mei, dan begint het serieuze zonnewerk want buitentemp. nog niet te hoog en een gunstigere instraling dan in volle zomer. Bij een dubbeltariefmeter loop je ook nog eens lekker op te wekken in de dure uren. Als je het een beetje kan uitkienen dan reken je straks enkel af in het lage tarief.
    You're hooked...

    Ik heb slecht nieuws voor je: de overheid wil af van het salderingssysteem, zodat je je belastingvoordeel over je eigen gebruik gaat kwijtraken.
    Ik heb geen details, maar als dit doorgaat zijn zonnecellen in een klap niet meer rendabel.
    
    
    6. Het opwekken van zonnestroom is nu al goedkoper dan het opwekken van grijze stroom.
    De consument lijkt die grens al te hebben bereikt. Ook zonder subsidie is een zonnepaneel inmiddels rendabel. Maar dat is te danken aan het salderingssysteem, legt Sinke uit.
    
    "De consument mag zijn opgewekte stroom verrekenen met ingekochte stroom. Daarmee bedraagt de waarde van zonnestroom meer dan 20 eurocent per kilowattuur en brengt het zonnepaneel zijn geld op. Maar het opwekken van grijze stroom kost minder dan 10 cent per kilowattuur.

    Als altijd is de overheid ook hier onbetrouwbaar. Voorlopig is eea vastgelegd, voor wat het waard is, tot 2020. Een tussentijdse evaluatie zal in 2017 plaatsvinden.

    Vanaf dan is het misschien al mogelijk om rendabel energie thuis op te slaan. De technieken hiervoor bestaan al en worden steeds beter.
    
    Nogmaals: uiteindelijk gaan we allemaal zelfvoorzienend worden.

    Solar power developers in Telangana seeks clarity on land and evacuation issues
    
    Business Standard reported that ahead of a scheduled pre-bid meeting for the development of 2,000 MW solar power in Telangana, the state officials have assured private developers that the government would provide all support, including land, to them.
    
    Speaking at a 2 day ‘EQ Solar Leadership Summit’ here on Wednesday, Mr Jayesh Ranjan MD of Telangana State Industrial Infrastructure Corporation said that the government was holding brain-storming sessions on ways to facilitate the development of solar projects by taking care of land and evacuation issues.
    
    Earlier this month, the state government had notified the bidding schedule beginning with the filing of request for selection by prospective developers to award projects with an aggregate capacity of around 2,000 MW through tariff-based competitive bidding.
    
    Officials said that the government will enter into power purchase agreements with the successful bidders for procurement of solar power for a period of 25 years. Having 300 sunshine days in a year with average insolation of 5.0 KWh/m2, the state would offer a short gestation period for such projects.
    
    While May 15th has been set as the deadline for submission of bids by private developers, successful bidders would be issued letters of intent on June 22nd and finally PPAs would be signed on July 21st 2015. The government has set an upper ceiling for procurement tariff at INR 6.45 per unit for group 1 bids which would inject power at 33/11 KV substation level and at INR 6.32 per unit for projects that are connected to the grid at 133/33 KV and above voltage levels.
    
    Mr Bhupesh Trivedi associate director of Rolta Power said that investors had enough funds to develop solar projects though practical problems such as land and other issues had been holding them back from aggressively pursuing the projects.
    
    He also suggested the government should provide room for more small size projects with 3 MW capacity unlike in the earlier bidding process conducted for an aggregate capacity of 500 MW in which 70% to 80% projects went to big players.
    
    Mr C Narasimhan chairman of Indian solar association requested the state government to create a land bank for solar projects as the availability of land was the biggest problem in way of solar power development across the country. State power utilities are holding a pre-bid meeting on Friday with the prospective developers to clarify on various issues and motivate them to participate in the competitive bidding process.

    Solar power cost to be INR 4.50 a unit by December 2015
    
    PTI reported that Centre is working on innovative measures which will help in cutting down the cost of solar power by 25% to 35% to INR 4.50 per unit by December 2015.
    
    Mr Piyush Goyal, Power, Coal and New and Renewable Energy Minister said at a CII event that "You will see solar power in this country at INR 4.5 per unit."
    
    At present, solar power tariff is about INR 6 to INR 7 per unit.
    
    Mr Goyal said that "We are looking at bringing in innovative financing solutions and improve the counter party risk and bring down the cost of solar and wind energy."
    
    The minister said that there may be escalation in solar power tariff in the future but it would not be significant.
    
    He said that "There may be 1% increment a year in the next 25 years but it will still be less than what we are paying today."
    
    The government has also engaged PricewaterhouseCoopers as consultant for formulation of a plan to scale up solar energy in the country.
    
    The work undertaken by PwC include assessing the power scenario and analysing the efficacy of ongoing initiatives by the Ministry of New and Renewable Energy as well as brining out a realistic demand projection and capacity addition plan.
    
    The central government plans to increase the solar power capacity to 1,00,000 MW by 2022 from the current 3,000 MW.
    
    On the fossil fuel-front the minister said that the government is working at increasing the production of coking coal used in the steel industry.
    
    He said that "We need to rapidly increase our coking coal production and I hope that the country will not have to import coal in the next two and a half years."
    
    The minister also said that the one billion tonnes coal production target of Coal India by 2020 is achievable.

    Brazil eyes solar power as drought hits hydropower resources
    
    RTCC reported that Brazil’s devastating drought could have the unexpected consequence of finally prompting one of the sunniest countries in the world to take solar power seriously.
    
    The combination of an imminent energy crisis, as reservoir levels fall too low to generate power, and the appointment of a more open-minded Energy Minister promise a rapid change in the situation.
    
    The drought, which has produced a crisis in the supply of water, has seen a dramatic drop in the levels of the reservoirs that supply dozens of hydroelectric dams in the southeast and centre west, Brazil’s industrial powerhouse and major population centre.
    
    As Brazil now begins the 7 month dry period, when rain is traditionally sparse, the reservoirs in the drought-affected region could fall to as little as 10% of their capacity, which the new Mines and Energy Minister, Eduardo Braga, admits would be 'catastrophic' for energy security.
    
    It means that plans to introduce solar energy into the energy mix are at last being considered as Brazil seeks alternatives to hydroelectric dam, on which it relies for up to 80% of its energy.
    
    The contribution of wind power, produced by onshore wind farms in the Northeast and South, has begun to grow.
    
    But solar energy, dubbed 'a fantasy' by President Mr Dilma Rousseff just a few years ago, has been ignored. Only 400 homes in Brazil have photovoltaic panels installed on their roofs, because the cost is so prohibitive.
    
    However, Braga has announced plans to turn dozens of hydroelectric dams in the southeast and centre west, which run the risk of becoming white elephants as the waters diminish, into solar energy farms.
    
    Thousands of solar panels attached to buoys would be floated on the surface of the dwindling reservoirs to provide an alternative source of power.
    
    Ministry officials have calculated they could add up to 15,000 MW of power, which is higher than the maximum capacity of 2 of Brazil's latest Amazon megadams, Jirau, on the Madeira river and the controversial Belo Monte, on the Xingu.
    
    The solar panels would have the added advantage of reducing water evaporation while at the same time being cooled by the water, boosting their conversion efficiency.
    
    Pilot projects are about to begin on 2 dams owned by state companies, Sobradinho, on the Sao Francisco river in Bahia, and Balbina, on the Uatumã river in the Amazon. If they are successful, the solar panels will be introduced into the dams in the southeast and centre west.
    
    Brazil will not be the first country to experiment with floating solar power. Australia is trying it out with PV panels on the surface area of a wastewater treatment facility in Jamestown, South Australia. Their energy will power the plant.
    
    Tax breaks for the production of photovoltaic panels have also been promised by Brazil’s Energy Minister, who also plans to introduce new rules to encourage the use of solar panels on buildings with large roof areas.
    
    Two more auctions for solar power will be held this year. In the first such auction, held at the end of last year, 31 solar plants were chosen to provide a total capacity of 1,048 MW by 2017. The price was just under USD 90 per MW among the lowest in the world.
    
    According to some sources, solar energy potential is equivalent to 20 times the total of all the present installed capacity of electrical energy.
    
    Factors that contributed to the low cost were the strong solar radiation factor in Brazil, and the fact that many solar parks would be installed in the same areas as wind farms, reducing the need to acquire land or build new transmission lines.
    
    The 20 year contracts for energy supply involve investments of USD 1.67 billion and many foreign companies are already jostling to get a place in the Brazilian sun, in what promises to be a rapidly expanding market in a few years’ time.
    
    Spanish, Canadian, American, Italian and Chinese companies already have a foot in the door. And as soon as the government and its development bank, the BNDES, come up with the promised tax breaks and incentives, the solar industry could take off.

    Telangana government plans solar power for pumps - Official
    
    A senior official of Telangana energy department said that the Telangana government is considering a plan to supply 7 hours of power to farms through solar projects. An action plan will be submitted to the government for 7 hours of solar and 2 hours of thermal power to agricultural fields.
    
    The offcial said that “Agricultural pump sets needed to be replaced with solar ones by the Rabi season. For this, we would like to use the INR 500 crore loan given by the Power Finance Corporation, but this needs ratification from the government.”
    
    A power expert said that the Telangana government has informed the Central power ministry, which visited the state to get the actual power position for the proposed 24x7 PFA scheme, that it has 20 lakh agricultural pump sets. But it is a gigantic task to convert all pump sets into solar ones.
    
    According to statistics, agricultural consumption is expected to be 7,528 million units in the year 2015 to 2016. In an attempt to rope in more players, the Telangana government has put a district-wise ceiling on the generation of solar power. Nalgonda has been awarded projects up to 600 MW followed by Medak with 500 MW. The ceiling for other districts was 400 MW each.
    
    Telangana has recently started solar projects with a generating capacity of 550 MW. It has also invited tenders for the purchase of 2,000 MW solar power.
    
    The tariff was approved by the government earlier but several companies have stated that it cannot meet their expenses. They demanded a rate of INR 7 per KWh. The discoms will be convening a pre-bid meeting on April 10th with prospective bidders at the TSSPDCL office.
