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.

Wind Power in Gujarat: 10-fold increase in 6 years

Quote:
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.

Highest potential for RE generation in Gujarat: Report

The western Indian state of Gujarat is bestowed with immense potential to generate renewable energy from various sources like solar, wind, biomass, small hydro power (SHP) and tidal which accounts to around 14 per cent of country’s total potential, according to a report by the Central Statistical Office (CSO), government of India.

The report titled- ‘Energy Statistics 2012′- has been brought out by the CSO which is under the ministry of Statistics and Programme Implementation (MOSPI) to help planners and researchers. It says that the geographic distribution of the estimated potential across Gujarat is the highest in the country.

The report estimated total potential for renewable power generation in the country at 89760 MW by end of financial year 2010-11. It reveals that Gujarat has the highest share of about 14 (12,489 MW), followed by Karnataka and Maharashtra with 12 per cent share (11,071 MW) and 11 per cent share (9596 MW) respectively. However, when it comes to installed capacity of grid interactive renewable power Gujarat does not figure in the top three.

The report estimates Gujarat’s potential for generating wind power at 10,609 MW, SHP at 197 MW, biomass power at 1,221 MW, cogeneration bagasse at 350 MW and waste to energy at 112 MW.

Wind, Solar to power Gandhinagar’s mutli-utility centers

According to reports, in order to make multi-utility spaces in urban areas viable and add to the revenue of civic agencies, Gandhinagar Urban Development Authority (Guda) plans to set up windmill-powered utility centers.

This unique utility centre will act as a bus-stop, have space for advertisement display, a small cafeteria and sitting space.

The centre will be powered by a small windmill and a solar panel and will draw little electricity from the main grid.

“We already have a model prepared of the same. The centre will act as a source of revenue for Guda. The advertisement will be lit from the power drawn from wind and solar sources. On days when the unconventional power is not available, the center will have option to switch to grid power. But then the chances of the wind or sun being absent simultaneously are few,” said chairman of Guda Ashok Bhavsar.

Guda has already shared model of the multi-utility center with the urban development authority and nearby nagarpalikas. “The estimated cost is being analyzed. It depends on what combination of hybrid power should one go for while constructing these centers,” the chairman said.

GMDC to invest Rs 300 Cr for Wind Power generation

Quote:
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.

Surat to set up 8.4 MW wind farm project

According to reports, following the success of the past, Surat Municipal Corporation (SMC) has taken one more initiative to go green and decided to set up another wind power project of nearly 8.4 megawatt capacity. The wind mill to come up in coastal Saurastra in Porbandar and will cost the civic body Rs 63 cores but once commissioned it will give 1.58 crore units of electricity which is nearly 11 per cent of the total consumption of the civic body.

Municipal Commissioner MK Das talking to TOI said, “We have called for tender proposals for the project and once they are approved by standing committee we work towards setting up this plant.” Talking to TOI Lights and fire committee chairman GC Gopani said, “We approved the estimates of Rs 52.08 crore for the construction and Rs 10.65 crore for the operation and maintenance of the wind mill for the period of ten years.” The wind mill will be of the capacity of 7.5 megawatt to 8.4 megawatt capacity depending up on wind turbine generation (WTG). The unit will produce 1.76 crore units of power of which SMC will be able to use or get credit for 1.58 crore units, after deducting 10 per cent loss.

“We plan to commission this before March 2013.” Said Gopani. SMC is planning to use the credit from generation of power from this project in the expenses of Katargam water works and water distribution centers HT services. SMC is the first body to have two of its wind mills operational at odedar of Porbandar district in Saurastra generating electricity up to 1.5 megawatt each.

The initiatives of SMC in going green and helping the environment from the effects of climate change by taking number of initiatives are first of its kind and apart from Wind power civic body has started programmes to generate power from solar energy. Main office at Mugalisarai and Science center will also be equipped with solar power generating units by the end of the year.

Ahmedabad-Gandhinagar metro rail be powered by 20MW wind power plant

According to reports, in a first in the country, the Rs 15,000-crore Ahmedabad-Gandhinagar Metro Rail project is likely to have a dedicated 20 MW wind power generation plant to run its trains and meet power requirements at its stations and other utilities.

The Special Purpose Vehicle (SPV) for the project, Metro Link Express for Gandhinagar and Ahmedabad (MEGA) Company Limited, recently invited expressions of interest from companies that are in wind power generation to set up and run the dedicated wind farm for the Metro project.

Sources said this would be the first Metro rail project in the country to run on “green power” for which carbon credits would also be claimed.

The capital cost of 1 MW of wind power is Rs 4.5-6.85 crore, which is slightly higher than the cost of fossil fuel power. However, the running cost of a wind farm is very low as the fuel cost is zero and cost of operations and maintenance are very low.

The likely cost of a wind power plant dedicated for Metro rail is around Rs 110 to Rs 120 crore.

The Metro rail is proposed to cover a 44-km route in its first phase. Later, the government also plans to link Dholera with Ahmedabad by the Metro rail.

The state government first came out with Metro rail proposal in in 2005 and it was accepted by the Centre in 2006.

Once complete, the Metro rail is estimated to ferry 17 lakh commuters daily.

Gujarat govt revive tidal policy

Quote:
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.

SSNNL sees hydro power in Narmada




Quote:
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.

Gujarat to tap geothermal energy for power generation

Quote:
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.
