Solar power projects miss deadline

About 325 days of good sunshine in a year has still cast a shadow over the concentratedsolar power projects in the state. A major initiative of the Ministry of New and Renewable Energy (MNRE) and the state government to promote ecologically sustainable growth while addressing energy security is caught in the warp.

Four of the five concentrated solar power, CSP projects in Rajasthan, totaling a capacity of 470 MW, allotted under the first phase of Jawaharlal Nehru National Solar Mission (JNNSM) are running way behind schedule and have missed the scheduled commissioning, May 9 deadline. Now considering that these projects are being built for the first time in India, the ministry has decided to defer the penalty of Rs 1 lakh/MW/day and extend the deadline of commissioning the projects by 10 months. Under contracts awarded in December 2010, the plants would else have had to pay about 2.3 billion rupees ($42.5 million) in late penalties.

“This is the first time solar-thermal projects are being built in India and we want them to succeed. All developers are building CSP for the first time and it is a learning period. The technology is new and there are only two companies in the world that supply components, like heat transfer fluid (HTF) and mirrors that has resulted in the delay,” said Tarun Kapoor joint secretary Ministry of New and Renewable Energy.

While 50 MW Godavari Green Energy Ltd is the only CSP project in Rajasthan that would be commissioned this year, all other projects are way behind schedule. Lack of accurate and ground measured Direct Natural Irradiance, DNI data has been one of the main reasons for delay in project execution. Due to significantly lower DNI at ground level, than published data available earlier, the projects had to be re-engineered. This re-engineering also impacted the procurement process as quantity, design, specifications of most components of the solar field had to be revised. It also resulted in requirement of additional land for the developers.

Besides, developers feel that the commissioning period of 28 months was overambitious. The total time period of 28 months for completing all activities including land acquisition, financing, development of infrastructure (for water supply, power evacuation, etc) and construction of the project is very challenging. Considering the fact that these projects are happening for the first time in the country, the time provided is insufficient.

Godawari Green Energy, the first to commission a CSP plant under the JNNSM in India

Godawari Green Energy Limited (GGEL) has won the race to commission the first Concentrated Solar Power plant developed under the Jawaharlal Nerhu National Solar Mission (JNNSM) promoted by India’s government to boost the solar generation across India.

The widely criticized CSP program included in the JNNSM has resulted a failure in its first phase, if we only consider the established deadline to commission the projects. Indeed, none of the plants has met the timeframe to put the plants on line.

However, the plant promoted by Hira Group’s subsidiary GGEL has been very near, just a few days over the deadline. This fact may suggest that the program was correct and the companies that were awarded in the bidding process have failed in their forecasts.

Gujarat looking to promote the CSP advantage

As India’s National Solar Mission takes a back seat for concentrated solar power projects, regional opportunities have sprung to the fore – and Gujarat intends to capitalize.

When it was announced in December that the CSP allocation of the National Solar Mission would be delayed, developers began looking further afield in the quest for new projects. Gujarat has been pushing hard to promote renewables in the state, so now could be the time for CSP to lay a claim there.

There are a number of factors that make Gujarat attractive to CSP, according to Dr. Ketan Shukla, Secretary at the Gujarat Electricity Regulatory Commission (GERC). In a recent presentation, Dr. Shukla noted the availability of land in areas of high solar radiation, high water availability (particularly in the north of Gujarat) and strong infrastructure (a road network of 74,000Km) as positives that the industry should consider.

“The North Western part of India, particularly Gujarat and Rajasthan, gets high levels of solar radiation through most of the year” Dr. Shukla explained. In terms of policy, a Solar Power Policy was initiated in 2009 offering solar thermal a tariff of Rs. 11.55/kWh.

Gujarat will be discussed in further detail at the CSP Today India 2013 conference, taking place 12-13 March in New Delhi. Attendees will also hear from Pranav Mehta, Chairman of the Solar Energy Association of Gujarat, to get to grips with the opportunities open there.

CSP industry to discuss 2013 challenges in New Delhi this March

Leaders of the concentrated solar power industry in India will discuss upcoming challenges as PV competition intensifies.

Shubhi Gupta of Flareum Technologies, one of the companies speaking at CSP Today India 2013, explained that CSP players must answer a number of questions in India in the next 12 months – and support should come from the Government. “The Government needs to place more emphasis on solar component manufacturing, providing and ensuring adequate infrastructure, land, assured power and water supply, soft and easy loans with a clear vision to make the country a global solar hub.” Gupta explained.

Gupta also explained a key reason why the photovoltaic segment has overtaken CSP in India. “Technically we see a lot of research happening for photovoltaic technology, whereas not much has happened in the CSP side. Hence we can expect more R&D activities on this technology would help reduce the cost and make it even more efficient.

Also it is expected the industry segments that use heat or steam for their product process would be opting for alternatives for non-renewable fuel, and since the steam generating systems can be easily integrated with the already existing systems of the facility they are very convenient.”

Integration with conventional power plants, as well as CSP technology advancements and cost reduction are key themes of the CSP Today India 2013 agenda. Top experts from STEAG, Ingeteam, SENER India, Termopower and Abantia Instalaciones will join Flareum in discussing strategies for boosting CSP technology and competing with other energy sources.

SCHOTT Solar Receivers energize India’s first ever Concentrated Solar Power Plant

SCHOTT Solar has set a new milestone in the development of India’s renewable energy sector: Germany’s pioneering solar company announced today it has completed the shipment of more than 17,000 SCHOTT PTR®70 receivers to Godawari Green Energy Ltd. These high technology components form the heart of India’s first Concentrated Solar Power (CSP) plant. The 50 MW project is located near Nokh Village, Pokhran Tehsil, Jaisalmer District. It is contracted by Lauren Engineers & Constructors (I) Private Limited (LECI) and well on track for completion in 2013. This will make it India’s first ever utility to generate electricity by using sophisticated CSP technology. Under Phase one of the government’s Jawaharlal Nehru Solar Mission a total of 500 MW of CSP projects are planned. This destines this highly efficient technology to emerge as an important new contributor to India’s energy-mix.

“SCHOTT PTR® 70 receivers were an easy choice for us to make after carefully analyzing this impressive product’s outstanding track record with other large-scale CSP installations in other parts of the world. And this turned out to be a wise decision, considering what a reliable partner SCHOTT Solar has been. In any case, we are proud to be able to leverage their wealth of knowledge in this fast-growing field,” explained Mr. J P Tiwari, CEO of Godawari Green Energy.

“Size, quality and execution speed of this landmark project prove India’s resolve to make CSP technology a pillar in its quest to develop solar power. With abundant sunshine and vast power needs, the country is best placed to utilize such advanced solar technology to its full advantage,” notes Dr. Patrick Markschläger, Managing Director at SCHOTT Solar CSP, adding: “Success in this key growth market further consolidates our position as the world’s leading supplier of CSP high-performance receivers.”

India’s Jawaharlal Nehru Solar Mission recognizes CSP as a critical technology. CSP stations with parabolic trough technology are steam-driven power stations that generate electricity from heat. Parabolic mirrors arranged in long rows concentrate the solar radiation onto the receiver inside which a carrier liquid is heated to almost 400 degrees Celsius. The heat, in turn, is used to raise steam that drives a conventional turbine and thus creates electricity. What’s unique about CSP electricity is its dispatchability. In the form of heat, the energy can easily be stored and fed into the grid when power is really needed. CSP solar power plants can continue to generate electricity long after the sun has set or has been obscured by clouds. This facilitates load management in grids – a factor destined to be of increasing importance as the contribution of solar energy to India’s electricity mix rises.

About SCHOTT PTR® 70 receiver

The SCHOTT PTR® 70 receiver that is being used in India’s first CSP project plays a key role in increasing the efficiency and longevity of modern solar power plants. The more sunlight they convert into heat, the better the performance of the entire plant. A full four meters in length, the SCHOTT PTR® 70 consists of a metal absorber tube that contains the heat carrier liquid, surrounded by an isolating vacuum and a special glass tube. Due to the combination of materials with matching coefficients of thermal expansion, the glass-to-metal seal of the SCHOTT PTR® 70 receiver can handle dramatic temperature changes and ensures vacuum stability. Moreover, SCHOTT Solar developed special coatings that allow for transmission of almost all of the sun’s radiation while emitting hardly any heat. The German company keeps on improving the design of the receiver to increase the active aperture area and thus its efficiency. Today, SCHOTT Solar is market and technology leader and has been supplying almost 1 million receivers to projects all over the world.



SCHOTT is an international technology group with more than 125 years of experience in the areas of specialty glasses and materials and advanced technologies. SCHOTT ranks number one in the world with many of its products. Its core markets are the household appliance, pharmaceuticals, electronics, optics, solar power, transportation and architecture industries. The company is strongly committed to contributing to its customers’ success and making SCHOTT an important part of people’s lives with high-quality products and intelligent solutions. SCHOTT is committed to managing its business in a sustainable manner and supporting its employees, society and the environment. The SCHOTT Group maintains close proximity to its customers with manufacturing and sales units in all major markets. Its workforce of around 17,000 employees generated worldwide sales of approximately 2.9 billion euros for the 2010/2011 fiscal year. SCHOTT AG, with its headquarters in Mainz (Germany) is owned by the Carl Zeiss Foundation.


India’s CSP projects lie in wait

The Jawaharlal Nehru National Solar Mission (JNNSM) had a lot of promise when it took off in 2008, but insufficient accurate DNI data, the unclear future of government subsidies, challenges in financing projects, and the need for a local manufacturing base, are all issues that could deter CSP progress in India.


Why the delay?


The first batch of Phase 1 allotted 650MW of solar projects: 500MW for solar thermal and 150 MW for solar PV. While most of the PV projects under this batch, the Migration scheme, and the Rooftop PV and Small Solar Power Generation Programme (RPSSGP) have been commissioned, the 500MW of CSP projects through the JNNSM are still in the construction phase. So far, only one 2.5MW CSP plant is working – the scalable ACME Telepower solar tower in Rajasthan – and developers have until May 2013 to commission CSP projects under the first batch.


“The date for commissioning of CSP projects is still far and therefore, I wouldn’t conclude that developers are behind in completing their CSP projects. However, some of them have asked for extension of time mainly because of delay in availability of heat transfer fluid”, Tarun Kapoor, joint secretary of India’s Ministry of New and Renewable Energy (MNRE), tells CSP Today.


Some local CSP developers also claim that efficiencies and DNI data from public sources was highly misleading during Phase 1, partly due to the inadequate resources of validated data for various sites in India, with different players claiming to hold accurate information.


This led to difficulties in the execution of projects, prompting the MNRE to conduct ground solar monitoring at several locations. “Measures like the MNRE’s efforts to set up solar radiation measurement stations at various regions are increasing investors’ confidence for funding projects in India”, Hari Chereddi, managing director of Hyderabad-based Sujana Energy, tells CSP Today.

Although the JNNSM is trying to encourage the development of both PV and CSP technologies by giving each equal weight, Chereddi points out that “by allotting specific quotas for each technology, the JNNSM is dictating the ratio of technology that can be built, rather than allowing the market to select the most efficient and cost-effective technology for India”.


Financing and technology dilemmas


Another large issue has been that the solar sector is comparatively new to financial institutions in the country, as only a few of them have seen the full cycle of solar power projects and how they behave. For this reason, most financial institutions are looking at solar power projects very cautiously.


“Some institutions have expressed fears about extending finance on concerns that the technology may not perform as expected and that developers may not get paid on time”, says Chereddi. Furthermore, PV prices have fallen rapidly over the past two years and there has been no consensus on what price will make a CSP plant profitable.


Scarcity of water in some of the high-DNI areas poses yet another challenge. For example, about a 35,000km area of the Thar Desert has been set aside for solar power projects, which receives 2,000kWh of sunlight radiation per square metre annually. Although this allocated region could potentially generate between 700GW-2100GW of energy, it lacks sufficient water.


Most CSP technologies used today are water based, and despite the availability of some non-water based CSP systems, they are not yet cost-competitive. In addition, there is the challenge of connecting to the main grids, as most parts of the region’s CSP-installed land lack transmission lines.

MNRE team visits Spanish CSP plants

An Indian delegation headed by Mr. Gireesh Pradhan, Secretary of the Ministry of New and Renewable Energy (MNRE), during its visit to Spain made visits to some of the Concentrating Solar Thermal Power (CSP) plants and met with Protermosolar on April 18.

Impressed by the CSP plants, Mr. Pradhan declared the strong commitment of India with solar energy (both PV and STE). Regarding the ongoing Solar Mission program, he is convinced that the first set of 500 MW CSP plants will be a success in spite of the big criticisms that India has received from many countries regarding the bidding process over the FiT.

Luis Crespo, General Secretary of Protermosolar and President of ESTELA expressed his full confidence on the commitment of the relevant Indian companies which are promoting the first projects in order to make them happen.

Crespo presented the big advantages of CSP plants for India regarding potential, dispatchability, grid stability and macroeconomics impacts. He foresees a major role of CSP in the future Indian generation mix. He also said that Spain made a big effort in supporting the first generation o new plants and now countries like India have an easier task although continuous support is still needed in order to profit from CSP technology as soon as possible.

Some Spanish companies like Abengoa, Acciona and ACS attended the meeting as well. They expressed their interest and commitments to collaborate with the Indian Government and local partners in the deployment of CSP in the country. Protermosolar and ESTELA offered a complete disposal to provide information and advice to the Indian Government. They will keep in touch regarding the future Indian plans in terms of both technology development and plant deployment.

AREVA : India: AREVA awarded contract by Reliance to build Asia’s largest concentrated solar power installation

AREVA Solar, an AREVA subsidiary, has been awarded a contract by the Indian group Reliance Power Limited to build a 250 megawatt (MW) concentrated solar power (CSP) installation in India, which will become the largest in all of Asia. The project will help advance India’s goal of adding 20,000 MW of solar energy by 2022 and will result in the avoidance of approximately 557,000 tons of CO2 emissions per year compared to a similar sized coal-fired power plant.

Under the contract, AREVA will build two 125 MW CSP plants using its Compact Linear Fresnel Reflector (CLFR) technologyand will provide construction management services for the project. The first phase of the project is under construction, with a target commercial operation date of May 2013. The solar power plants will be located in Rajasthan.

JP Chalasani, CEO of Reliance Power, stated: “Reliance Power is proud to be a leader in India’s clean energy future. Today’s announcement is just the beginning. We look forward to working with AREVA Solar in helping meet India’s clean energy goals through this project.”

AREVA CEO Luc Oursel stated: “AREVA is delighted to help deliver on the promise of India’s progressive solar energy goals and to advance Reliance’s bold vision for a global clean energy portfolio. We will leverage our best-in-class experience to help make India and Reliance global solar industry leaders. Following our success in the French wind offshore sector, this contract reinforces the AREVA strategy in renewable energies.”

The Reliance contract solidifies AREVA Solar’s position as a leading global supplier of CSP solutions for large-scale standalone power plants, power augmentation of fossil-fired power plants and solar hybrid applications, and follows on a series of successes. This project also further strengthens and diversifies AREVA’s low-carbon energy hub in India.

In Australia, AREVA Solar was awarded a contract to build a 44 MW solar thermal addition to the coal-fired Kogan Creek power station, and its energy consortium was selected as the preferred bidder for a 250 MW CLFR power plant under Australia’s Solar Flagships Program. And in the USA, AREVA Solar recently announced a partnership with Tucson Electric Power on a solar augmentation project in Arizona.

In total, AREVA Solar currently has more than 500 MW of CSP projects in operation, under construction or in advanced development, making AREVA one the fastest-growing CSP technology providers.

Solar thermal exempt from Indian import duty

Solar thermal plant equipment will be exempt from import duty in India. India’s finance minister made the announcement today. The belief is that project costs could be lowered as a result. Photovoltaics was not mentioned, however.

India solar photovoltaic park 

481.48 MW worth of photovoltaics has been installed in India, compared to 8.5 MW of CSP.



“In order to fully realize our potential in the realm of solar energy, solar thermal projects need encouragement,” stated Pranab Mukherjee. “I propose to fully exempt plant and equipment, etc. for the initial setting up of such projects from special countervailing duties (anti-subsidy import duty).”

According to research company, Bridge to India, the Indian solar thermal sector has “significantly lagged behind” its photovoltaics counterpart. To date, it explains, just 8.5 megawatts (MW) worth of concentrated solar power (CSP) have been installed in the country, compared to 481.48 MW worth of photovoltaics.

There is also said to be no domestic manufacturing base for CSP equipment, and only “a handful” of international suppliers. “As such, developers are finding it difficult to find reliable, low-cost options, a necessity to make their projects viable at the low tariffs following the NSM [National Solar Mission] auctions in the year 2011. With an absence of CSP technology in India and a lack of projects for reference, banks are exceptionally wary of funding CSP projects. This has led to stunted growth of the Indian CSP market,” explained Bridge to India.

Another reason why the CSP market has not taken off as much as photovoltaics, it said, is due to water shortages in the country. “CSP as a technology faces water issues that will require … developers [to] come up with creative plant cooling solutions. There is also consternation about the 30 percent local content requirement,” continued the statement.

Overall, Bridge to India believes that the announcement is positive, and will help to lower CSP project costs.
