ReNew Power commissions 25 MW wind power project in Gujarat

In keeping with its commitment to become one of the leading renewable energy producers in India, ReNew Wind Power Pvt. Ltd., an independent power producer, has commissioned its first wind farm project at Jasdan, Rajkot district, Gujarat. The 25.2 MW facility was inaugurated by the Chief Minister of Gujarat, Mr. Narendra Modi.

Construction of the project began in October 2011 and was completed in March 2012. This facility comprises of 12 units of Suzlon S88 wind turbines with 2.1 MW capacity each. The project is selling its output under a under long-term PPA contract to Gujarat Urja Vikas Nigam Ltd (23.1 MW), and the remaining output to Philips India (2.1 MW).

Speaking at the inauguration ceremony, Mr. Modi said, “It gives me immense pleasure to welcome ReNew Power to Gujarat, our state has been a dominant player in the wind energy market and we look forward to have more and more projects and investments in the state to help build sustainable power source for energy starved India.”

The project demonstrates ReNew Power’s vision in recognizing the challenge of climate change, and its responsibility to combat it. “It gives us great pride to partner with the Government of Gujarat with its far reaching vision for wind potential in the state. We thank Mr. Modi for extending his support to ReNew Power and encouraging us by gracing today’s occasion,” Mr. Sumant Sinha, Founder Chairman and CEO, ReNew Power said.

Mr. Sinha added that in September 2011, global major, Goldman Sachs, had infused Rs 1,000 crore as equity. ReNew Wind Power bought 12 turbines of 2.1 MW each for the project from Suzlon Energy. The PTC India Financial Services Ltd (PFC) financed the wind power project in a 70:30 debt-equity ratio.

Mr. Tulsi Tanti, Chairman, Suzlon Group, said that ReNew’s growth is a clear marker of the evolution of the Indian wind sector and its emergence as the world’s third largest market. “We are pleased to partner with ReNew, and look forward to building a long term partnership. We are confident that ReNew Power will play a leading role in shaping the wind sector of tomorrow,” he said.

GAIL plans to invest Rs. 620 crore to set up wind farms

Amid concerns of depleting stocks of fossil and climate change issues, GAIL India, the largest state-owned natural gas processing and distribution company in India has decided to increase its renewable energy portfolio. Encouraged by the initial results of 4.5 MW wind power project in Gujarat, GAIL plans to set up many more wind energy generation projects.

According to an internal plan document of the company, GAIL is also in the process of setting up a 100 MW WEG project in Karnataka and Tamil Nadu for commercial use with an estimated investment of Rs.620 crore. The company wants to get these projects during 2012-2013. Apart from the 100 MW in TN and Karnataka, the company is setting up another 14 MW WEG project in Gujarat partly for captive use in the State and partly for sale to the State utility.

To establish firm hold in the clean energy sector, Gail intends to invest big time. The wind potential states such as Andhra Pradesh, Gujarat, Kerala, Madhya Pradesh, Maharashtra and Rajasthan are also on the radar of the company to expand its presence in the wind energy sphere.

Gujarat government's focus on tapping renewable energy has led to sharp rise in the capacity to generate power using wind energy in the last few years

According to official data, wind farm generation capacity in the state has increased a staggering ten times in just six years.

A senior state government official said that total wind power generation capacity in the state as of March 31, 2012, stood at 2,884 MW, the second highest in the country, after Tamil Nadu, which has capacity of close to 7,000 MW.

"Gujarat overtook Maharashtra in terms of wind power generation capacity in 2011-12. Gujarat's wind power capacity rose to 2,884 MW, as compared with Maharashtra's 2,711 MW," said the official.

With the sharp rise, wind energy now accounts for over 20% of the total electricity generation capacity in the state, which stands at 13,914 MW. According to officials, it plays an important role in meeting demand for power.

Officials say that in absence of a clear roadmap, wind power generation capacity in the state was only 272 MW as of March 31, 2006. However, there has been no looking back since then. The wind power generation capacity in the state has gone up by around 300 MW or more every year hence.

The year 2011-12 saw addition of 790 MW of wind power capacity in the state, by far the highest ever in any year. The previous highest capacity addition during a year was 616 MW in 2007-08.

This was also the time when state government amended the Wind Power Policy, and raised power tariff from Rs3.37 per unit to Rs3.50 per unit, which was subsequently revised to Rs3.56 per unit.

However, in spite of the rapid steps taken to tap wind energy, the state is still a long way off the huge potential it offers. According to state government, wind power potential in the state is estimated at around 10,000 MW, most of it in the coastal areas of Saurashtra and Kutch.

"There is a lot of potential to generate clean and cheap energy by harnessing wind energy, and this is what we are focusing on," said DJ Pandian, principal secretary, energy & petrochemicals department.

Industry experts say that Rajasthan with 2,100 MW and Karnataka with 2,000 MW capacities are the other states which have tapped wind energy in a big way.

Gujarat Mineral Development Corporation (GMDC) has decided to invest Rs 300 crore for expanding its wind power generation capacity to 150 MW. GMDC already has around 100 MW of wind power generation capacity. The next project is likely to coming up at Bhanwad in Jamnagar district.

The Engineering procurement Contract for the wind farm has been awarded to Suzlon Energy. The project is likely to be commissioned in October.

On completion, the project would generate around 10 crore units of electricity each year. According to officials, the entire power pro-duced at the wind farm would be sold to Gujarat Urja Vikas Nigam Ltd (GUVNL). The present tariff for wind power is Rs 3.56 per unit.

The project will also general carbon credits for company.

The existing 100.50 MW wind power projects are located in coastal areas of Rajkot, Jamnagar and Porbandar. GMDC has also commissioned a 5 MW solar power plant at its Panandhro lignite mines in Kutch.

Relevant part to this thread is that students at LJ Institute of Engineering and Technology (Ahmedabad) have come up with a prototype of a windmill that uses a magnetic disc to help generate energy even when there is less wind.

After an initial gust of wind gets the windmill started, a North-South magnet mounted behind will help to keep the windmill turning even if no wind is present. This technology may be able to help windmills be installed in areas where there is less natural wind.

Seems like an interesting idea for sure, guess a lot depends on how much of a difference it can make.

AHMEDABAD: The state energy department has revived it policy to have power using tidal wave. A government resolution (GR) has been issued claiming it is "possible to produce tidal wave power at two spots - in the Gulf of Kutch near Mandva, and in the Gulf of Khambhat near Hazira.

GR, significantly, says that at the two spots, respectively, 200 MW and 300 MW of "tidal wave power can be produced". The decision to drop tidal wave power project was taken in early 2009 after the state government decided to slash down the cost of the Kalpasar project, proposed as a sweet water lake by damming the Gulf of Khambhat. While reviving the project, the GR said, Rs 25 crore have been set aside and handed over to the Gujarat Power Corporation Ltd to begin with the project.

The GR said, "In village Maska in taluka Mandvi, Kutch district, 16 hectares (ha) area has been acquired to kick-start the tidal wave project. The National Institute of Oceanography, Goa, has been asked to carry out marine environment impact assessment for tidal wave power." Meanwhile, Rs 25 crore have been set aside for soil investigation, topographical survey and geo-technical survey of the sea. Also, studies are being carried out on the type of turbines needed for tidal wave project.

The Sardar Sarovar Narmada Nigam Limited (SSNNL), which is executing the Narmada canal network, plans to generate hydro power by tapping the potential of billions of litres of water flowing in the canal.

The SSNNL plans to harness the hydro power potential by placing micro turbines at various locations in the Narmada canals, which are spread over thousands of kilometres in several districts.

“We have carried out preliminary studies to examine hydro power generation potential in the Narmada canals. The studies show that roughly 80 to 100 MW of hydro power can be generated by placing micro turbines in the canal,” said a senior SSNNL official.

However, capital cost of the project and other details such as cost of electricity generation are being worked out, he said further.

The state government is paying Rs15 per unit for every unit of power generated using solar energy. However, the cost of electricity generated using hydro power would not be more than Rs3-4 a unit.

“Hydro power is not only a clean source of energy, but also the cheapest. The only cost needed to be incurred is the initial capital cost,” he said.

The official explained that micro hydel turbines would be placed at specific places in the canal where the water falls.

“The force of the falling water would be used to harness hydro power and generate electricity,” he said.

SSNNL managing director S Jagadeesan was traveling and could not be contacted.

Another senior official of the corporation said that they plan to conduct a few more studies and appoint a consultant for the project in the near future.

“After the canal-top project, where solar power panels have been established atop the Narmada canal, this can be another unique project and will further consolidate Gujarat’s position as the hub of renewable energy,” the official said.

If things go according to plan, the installation of turbines in the canal could start as early as the next three to four months, say officials.

SURAT: After wind and solar power, Gujarat is all set to tap another unconventional source of energy.

The state government is planning to explore the feasibility of geothermal energy "We are meeting a delegation from Norwegian government to make a beginning of this untapped resource of energy next wee," said T Harinarayana, director, Gujarat Energy Research and Management ( GERMI).

Officials said that there is a potential to generate electricity through geothermal resources, which are available in plenty in the geothermal zone located in Cambay between Narmada and Tapi river. If the pilot project is successful, the state may plan generation of 10,000MW in a decade.

At present, 24 countries in the world generate geothermal electricity up to 10,715 megawatts (MW). The largest producer of this environment friendly electricity is USA that generates 3,086MW of electricity.

However, the production cost of electricity through geothermal process is high. "Yes, initial costs are high. It may take at least Rs 10 crore to produce one MW of electricity but the long term benefits are huge," said Harinarayana.

Anywhere on the earth, below one km of the surface there is tremendous amount of heat. This earthen heat can form the source of electricity. It is proved that if the temperature on the surface is 35 degrees, the temperature 10 metres below will be 26-27 degrees Centigrade but as one goes more deep, it goes up and is above 65 degrees centigrade.

In geothermal zones located across the country, the temperatures could be as high as 150-160 degree centigrade.

In Cambay, there are several bore holes, which were dug for oil exploration and have served their purpose. In the short term, they can be used for generating geothermal energy in the short term, he added.

Gujarat proposes to use binary cycle power plants and the geothermal power is considered safer and sustainable worldwide because the heat extraction is smaller compared to earth's heat content.

Moreover, the emission intensity of existing geothermal electric plants is roughly 122kg of carbon dioxide per megawatt-hour (MW.h ) of electricity, which is about one eighth of conventional coal-fired plant .

Gujarat generates just 2,219MU of its electricity through unconventional means out of the total 57,728 MU.
