Renewable Energy For India

I am starting this thread on Renewable Energy for India. There are pros and cons for topic.

To start of I am pro-Renewable Energy for India. This is major strategic initiative to kick the habit from Coal/Oil based products. Coal and Oil based products are major polluters contributing to tonnes of CO2 emission per year. India is currently producing around 70% of its energy from Coal based plants.

The current initiatives in renewable energy are a) Wind b) Jatropha biodiesel c) Solar Energy d) Ocean Tidal wave energy.

Wind is a well established technology and depends on the wind map of the country. The current estimates for Wind are around 60,000 MW on land. Offshore there is more potential.

Solar Energy is promising since India gets a lot of sunshine throughout the year. Some experts estimate that the Solar Energy Shone on India is sufficient to power its energy needs. The major stumbling blocks are solar to electric conversion are costly (though recent advances in California put it a grid parity cost, i.e. cost have come down to the same level as other conventional energy on a per unit basis).

One promising use for solar is home water heaters. This is not very expensive and people with independent homes can avail of this technology today. Lots of home have solar water heaters on their rooftops, the sun heating small tubes of water in a glass planel and hot water collected in an insulated tank. For those days that do not have sunlight an in-line heater element heats up water. So on balance, for a majority of the time people can enjoy hot water. Commercial establishments like laundries and hotels can make use of solar water heaters.

Coming to the issue of electricity from Solar there are various other alternatives that produce electricity. One instance in Seville, Spain uses reflecting mirrors to heat a liquid that runs an engine to produce electricity. This technology is being pursued by PG&E in Southern California for a 500 MW + plant. I believe that the best way to mitigate energy use is to have individual homes with Solar energy. During day time they can produce electricity returned to the grid and during night they take back from the grid. The savings could be substantial and conventional systems can augment deficit power.

India is also looking to increase its Nuclear Energy program.

Here is con argument from dis.agree

you cannot just shutdown & bring up coal based plants on a daily basis. they run for long durations and provide base load power. i am surprised you say that india has highest potential to reap solar energy. i am yet to see any decent paper on this.

while operational cost of solar power is near zero, it is highly capital intensive. there is still some distance to go from technology perspective. thin films is the most promising technology. it's efficiency is low but it compensates through lower capital needs. but even that on a levelized cost perpective is about 3-10 times expensive in western countries (at locations with good insolation levels). this however depends on discount rates used. you will not find indian banks lending at such low 5% interest rates. best you could hope for now is 10%. solar technology is still unproven & i doubt any serious bank would lend at all. you need equity but indian investors expect a much higher roi and so large scale solar projects would be financially unviable in india.

your view that oil imports benefit sheiks, while mainstream, is not free market thinking. they export oil and import other stuff. it is just a globalized economy. and that way we can argue against solar & wind energy as well. we are dependent capital intensive technology that are more expensive than fossils: usa for solar & europe for wind.

we definitely need to move away from coal, oil & gas. i am not saying this because of global warming of which i have reasons to be skeptical, but because oil production has started to decline for a few years now. gas too would follow very soon and coal possibly in next 2 decades. so, we must look at alternatives - nuclear & wind is the best short term option and in medium-long term solar.

indian government does not have that kind of money to subsidize such renewable energy. in any case, best way to get this done is to leave the markets to function freely. if state electricity boards allow/simplify sale of such power produced by independent producers directly to consumers and allow them to enter into long term contracts, i am sure we would soon see more such renewable energy generation.

Modi to inaugurate 500-MW solar park at Charanka village in Patan

Chief Minister Shri Narendra Modi will inaugurate Solar Park at Charanka village in Santalpur taluka of Patan district on December 30. This is considered as Gujarat’s huge step to tackle the issue of climate change.

The project will produce 500-MW of power with the use of renewable energy source. Use of solar energy will decrease the CO2 emission by 8 lakh million ton and save the bio-fuels like coal and gas. This is a first-ever project in entire Asia and with 500-MW of power production through solar energy, Gujarat will be the first state in the country to take such measure.

The solar park is likely to get solar energy for 330 days in a year amounting 5.5 to 6.0 KW per solar radiation every day. Gujarat government has agreed upon buying 933-MW of power under its new solar power policy, which is a remarkable move in the solar power sector of India.

The solar park at Charanka village will be constructed on the land of 2000-hectare for the phase-1. Out of which 1000-hectare is a waste land. Land acquisition process is still in progress. Works for the transmission of the power produced on the site have been started by Gujarat Energy Transmission Corporation Ltd (GETCO).

All the resources needed to produce electricity will be provided to the producer on the site ensuring a saving of time and money both for government and the energy-producers. In the phase-1, land will be acquired mainly by GPCL. Plots will be separated out and will be given to energy-developers for the lease of 30 years. Facilities like water, electricity, roads, rain water drainage, power transmission facility and others will be provided to power producers. Government is done with the onsite studies like topography survey, geotechnical survey and others.

State government will also establish projects like solar plant machinery manufacturing, research and development and others. Government will also work for training and research in order to provide technical manpower.

The project will also develop the remote villages like Charanka. Besides, the state will see an investment of around 7500-crore. The park will also have a need for assembling, civil works, electrical wiring, solar panel cleaning and others and thus will give employment to large number of local people.

It is worth noting that Gujarat is taking initiative in the use of wind energy, solar energy, hydro power and tidal energy. Gujarat has brought out its solar power policy in 2009 and it got unprecedented response. Vibrant Gujarat Global Summit held in 2009 saw MOUs with 57 companies for the production of 9606 MW. The new solar policy will likely to fetch an investment of Rs.65,000-crore in coming three to four years. Use of solar and other renewable energy will ensure low carbon emission, clean environment and an employment for around 40,000 people.
Asia's largest solar plant ready

A 30-MW solar power plant, the largest project of its kind in Asia, will be inaugurated by Chief Minister Narendra Modi on Friday.
The solar power plant has been set up by Moser Baer Projects in Gunthawada (Dalpatpura) village of Banaskantha, around 180 km from Ahmedabad. The company has invested Rs 450 crore for the twin solar power plants of 15 MW each.
This would be the fourth solar power plant to be commissioned in the state, the others being Gujarat Power Corporation's 1-MW plant, Lanco's 5-MW plant and Azure Power's 5-MW plant.
Officials said that Moser Baer had executed power purchase agreement (PPA) with Gujarat Urja Vikas Nigam Limited for 30 MW. As per the PPA, it would get Rs15 per unit of power for first 12 years and Rs 5 per unit from the 13th to 25th year.
In all, the state government has signed PPAs for 958 MW of solar power. The coming days are expected to see a number of solar power plants being commissioned.
DJ Pandian, principal secretary, energy and petrochemicals department of the state government, said that they expect around 300 MW of solar power generation capacity to be commissioned in the state before December 31.

What was dismissed as an outlandish announcement by chief minister Narendra Modi is turning into reality. Gujarat is all set to become the first state in the country to generate solar power through panels mounted on a water body, the Narmada canal to be specific.
The Gujarat State Electricity Corporation Limited (GSECL) has undertaken the pilot project of 1 MW, under which solar panels will be installed atop the Narmada canal for generating power. The solar panels would be laid on around 1 km of the Narmada canal for generating 1 MW of solar power.
The solar panels are being installed atop the Narmada branch canal near Chandrasan village of Mehsana’s Kadi taluka, around 75 km from Ahmedabad.
“This is a unique project. Something like this has not been undertaken in the country,” state energy minister, Saurabh Patel, told DNA.
Chief minister Narendra Modi had first spoken about the plan to install solar panels atop Narmada canal at a function in Gandhinagar on October 3, but the announcement was greeted with a lot of skepticism. But, the project is now in advanced stages.
The engineering, procurement and construction contract for the project has been awarded to Sun Edison at a cost of Rs17.71 crore. This is slightly higher than a traditional solar plant, where panels are mounted on land, which costs in the region of Rs14 — 15 crore for 1 MW.
According to state government, the project would have multiple and lasting benefits. “Installation of panels on the canal will help in doing away with the need to acquire land. Evaporation of lakhs of litres of water will be prevented since the canal will be covered. And, we will generate clean energy,” Patel said.
Another advantage of the project is that power generated will be supplied to villages alongside the canal, which will lead to lower transmission losses. Meanwhile, officials said that work on the project is progressing well.
"The project is in advanced stages of completion. We expect to complete it in the next two to three weeks, and start work on the next phase," Bhargav Mehta, director, Sun Edison, said. The second phase of the project envisages solar power generation capacity of 2 MW by installing solar panels atop the Narmada canal.

Looks something like this:

Found this piece of wisdom in the above article link...
Cant they also use methane generated from the rubbish tip as a source of energy?
I hope someone in govt gets into serious details on impact of solar PV power plants on over all health of power sector. I was hoping for quit long that someone will write article but it seems either I am unable to search article on issues or people in govt not aware. Solar PV must be stopped urgently as India is wasting precious resources on technology that can potentially derail coal based power plants or will force us to by very expensive power. India as a country with very high inefficiencies built in system can not afford expensive power when purchasing power of majority is very low & we are not competitive in global export market.

Solar PV is good for rich nations not poor nations. I hope Niti AAyog take note of the issues & take corrective action.
On the contrary if we install a battery like the one installed recently in South Australia by Tesla, the possiblites are endless.
battery makes solar even more expensive. Poor country like India with low purchasing power can not afford expensive power.
True, but we have to invest in our today for a better tomorrow. Coal will create polluted cities and will add to the cost where as solar and battery cost will come down.
I agree with you.The installed capacity of renewables like Solar and Wind are not as important it sounds. Both these can't be used 24x365 and even when they are used their efficiency factor is low. If we wanna replace coal, the best option is nuclear. Only nuclear power has the ability to follow demand. Since such a high dependancy on nuclear power is close to impossible in at least the medium term, thermal power plant would remain the primary power source for at least 2 decades.
The solar power can't be used 24x365 but batteries can. I dont think that coal will last 2 decades due to increasingly efficient tech gains in solar cell manufacturing. Recently in China, scientists worked out how to generate power from static energy generated by rain drops that roll off these solar panels.
