Just read news that Rajasthan has postponed its solar program. Though official reasons not given, people say they postponed it as the prices were too high for their liking. ( around Rs 10/kwh)..

And saw some criticizing Modi for going for prices as high as rs 15/kwh..

In retrospect, I am kinda happy that TN didn't jump into solar in a big way earlier like how Guj and Rajasthan did.

Only recently TN announced its plans for solar and by the time they think of implementing it, hope there would be further clarity in the sector.

Yes the prices of panels really plummeted in the last 12 months. Mainly because Germany is scaling back its program. It will take some time to overcome the resultant slackness.

so it means, cost of solar power is decreased?
we discussed it is around 10rs..is it come down to 7 or 8 rs?

Cost depends on a lot of factors and therefore should be given as a range. Currently that range is 7-10. Last year it was around 12-18.

Thanks Shyam.. already coal pricing is moving up... so in next few years it might move towards 5 rs or 6 rs. so if we get clean solar power at 7-10 rs., it will be good to have our investements towards solar power rather than thermal power right?

Thermal power is higher than 5 or 6 if you take the true price of coal. Indian thermal plants get coal at around half the international price. If they use coal from international markets (or if Coal India is allowed to sell coal in international markets), the cost of coal alone will be 3.5 to 4 rupees (I have posted the calculations earlier either in this thread or mega power thread - i forgot). If we add the plant cost, its financing, operations etc, the cost differential between solar and thermal is vanishing and wind is already cheaper than even subsidized coal.

The only advantage thermal power has is its reliability and its 'power on demand' capability. That is a huge advantage which can be matched only by nuclear power. It is this advantage rather than its cost advantage which will keep thermal energy relevant in the foreseeable future. Energy storage technology has to scale up to displace them.

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.

Travelled around Coimbatore - Palladam - Udumalpet - Pollachi last week and good to see the white towers at work, doing brisk business! Palladam - Udumalpet road at few points, one would be awestruck by the sheer number of these windmills and the beautiful sight it offers. I think those points are right in the high density wind areas.

A lot of windmills with two blades! and a quite a number of blades just resting! may be maintenance? or waiting for evacuation infra? repairs?!

Is the answer to India's energy future blowing in the Wind?

Felt very happy to see so many wind mills in action. Seeing wind mills with two blades for the first time. The ones with two blades were rotating very fast. Hope, govt does something in transmission network to evacuate power during peak period.

Indian firm develops own wind turbine technology

Quote:
In July last year, a windmill of 700 KW capacity began pumping electricity into the Tamil Nadu grid from Uthumalai, in Tirunelveli district. The windmill's claim to fame lies in the fact that it has been developed by an Indian company, Garuda Vaayu Shakthi Limited.

Only three other companies - Suzlon, WinWinD and Kenersys - own the technology for their turbines, says Vineeth Vijayaraghavan, Editor of the industry newsletter, Panchabuta.com. "Garuda's wind turbines are not just made in India but made for India."

The company is led by a team of home-grown entrepreneurs. Together, N. Srinivasan, P. Chandramouli and I.K. Pillai make a formidable team. Srinivasan is a chartered accountant who earlier headed the wind turbine business at Shriram EPC.

Chandramouli is a mechanical engineer and an IIM-Ahmedabad alumnus. Pillai is an expert in identifying wind sites. Until recently, he was helping wind turbine developers get possession of wind sites and obtain government clearances.

"It took us 18 months to develop the technology for two types of turbines, of 700 KW and 1,700 KW capacity," says Chandramouli. The 700 KW turbine in Uthumalai was the first one sold by Garuda. Tamil Nadu-based PMP Iron & Steel, the customer, is now in talks with the company for a 10 MW wind farm.

From their website:

Quote:
Garuda Vaayu Shakthi Limited (GVSL), headquartered in Chennai, India, has stepped into the field of wind energy with a commitment to provide efficient, productive output with foremost focus on after sales services.

...

GVSL has a manufacturing and assembly facility near Chennai, India, for the assembly of Wind Energy Generators. The choice of location was taken after a thorough study of available resources. The present location was approved considering its proximity to Chennai – The Wind Energy Capital of India and easy availability of skilled manpower ensuring benefits for all the stakeholders.

தமிழகம் சாதனை படைக்கும் அளவுக்கு, காற்றாலை மின் உற்பத்தி நேற்று ஒரே நாளில், 3,500 மெகாவாட்டைத் தாண்டியது. காற்றாலை மின் உற்பத்தியால், மின்வெட்டு நீக்கப்பட்டு, கடந்த சில தினங்களாக, 24 மணி நேர மின்சாரம் வழங்கப்படுகிறது.

மின் தட்டுப்பாட்டில் சிக்கியுள்ள தமிழகத்தில், கடந்த ஒரு மாதத்திற்கு முன்பு வரை, ஐந்து மணி நேரம் முதல் 10 மணி நேரம் வரை, மின் வெட்டு இருந்தது. ஆனால், மேற்குத் தொடர்ச்சி மலைப் பகுதிகளில் காற்று வீசும் பருவ காலம் துவங்கியுள்ளதால், காற்றாலை மின் உற்பத்தி கிடுகிடுவென உயர்ந்துள்ளது. நாளுக்கு நாள் காற்றாலை மின் உற்பத்தி அதிகரிக்கிறது. கடந்த வாரம் வரை, 2,500 மெகாவாட் வரை காற்றாலை மின்சாரம் உற்பத்தியானது. கடந்த சில தினங்களாக, 3,000 மெகாவாட்டைத் தாண்டியுள்ளது.

சாதனை: நேற்று காலையில், 3,516 மெகாவாட் அளவுக்கு அதிகபட்ச உற்பத்தியானது. காற்றாலை வரலாற்றில், இந்தியாவில் ஒரே நாளில் எந்த மாநிலத்திலும், இவ்வளவு அதிகமாக காற்றாலை மின்சாரம் உற்பத்தி ஆனதில்லை. இதுகுறித்து, மின்துறை உற்பத்திப் பிரிவு அதிகாரி ஒருவர் கூறியதாவது: தமிழகத்தில் மேற்கு தொடர்ச்சி மலைப் பகுதி, அதிக அளவு காற்றாலை மின்சார உற்பத்திக்கு உகந்த இடமாக உள்ளது. இயற்கையாகவே உயர்ந்த மலைகளும், உயரம் குறைந்த குன்றுகளும், கணவாய்ப் பகுதிகளும் கலந்த பகுதிகள், மேற்கு தொடர்ச்சி மலையில் அதிகம் உள்ளதால், பல இடங்களில் காற்றின் வேகம் அதிகமாக உள்ளது. அந்த இடங்களில் காற்றாலைகள் அதிகம் உள்ளதால், மின்சார உற்பத்தியும் அதிகரிக்கிறது. இவ்வாறு அவர் கூறினார்.

உற்பத்தி: காற்றாலை மின்சாரத்தை பொறுத்தவரை, நண்பகல் மற்றும் பகல் பொழுதை விட, நள்ளிரவிலும், காலையிலும் அதிக அளவுக்கு உற்பத்தியாகிறது. ஆனால், மாலை நேரம் மற்றும் தொழிற்சாலைகள் இயங்கும் பகல் நேரத்தில், காற்றாலை மின் உற்பத்தி நிலையற்றதாக உள்ளது. தற்போது, தமிழகத்தில் பல்வேறு மின் நிலைய கோளாறுகளாலும், புதிய திட்டங்களின் தாமதத்தாலும், மின்சாரப் பற்றாக்குறை உள்ள நிலையில், காற்றாலை மின்சாரம்தான் ஓரளவு நிம்மதியைக் கொடுத்து உள்ளது.

சென்னையை வாட்டும் மின்வெட்டு: காற்றாலை மின் உற்பத்தி அதிகரிப்பால், தமிழகத்தின் பெரும்பாலான இடங்களில் மின்வெட்டு நீக்கப்பட்டு, 24 மணி நேர மின்சாரம் வழங்கப்படுகிறது. மின்வெட்டு நேரம் பெருமளவு குறைக்கப்பட்டு உள்ளது. சென்னையில் மட்டும் இரண்டு மணி நேர கட்டாய மின்வெட்டு தொடர்கிறது. அக்னி வெயிலின் உச்சத்தில் தவிக்கும் சென்னை வாசிகள், மின்வெட்டால் கடும் இன்னலுக்கு ஆளாகி உள்ளனர். எனவே, சென்னையிலும் மின்வெட்டை ரத்து செய்ய, பொதுமக்கள் எதிர் பார்த்து உள்ளனர். இதேபோல், காற்றாலை மின்சாரம் கிடைக்கும் நேரங்களை கணக்கிட்டு, தொழிற்சாலைகளுக்குரிய மின்வெட்டையும் நீக்க வேண்டுமென கோரிக்கை எழுந்துள்ளது.
