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.

Biomass for Power Generation

The Government is providing various fiscal incentives for setting up of power generation projects from biomass throughout the country including capital subsidy linked with capacity and fiscal incentives such as concessional customs duty on import of machineries and components, excise duty exemption, accelerated depreciation on major components, relief from taxes and term loan from Indian Renewable Energy Development Agency (IREDA), and other financial institutions. This apart, preferential tariff is being provided for sale of power from commercial biomass power projects in 14 states. Promotional incentives are also provided for development of biomass power projects, capacity building, awareness creation etc.

The Indian Institute of Science, Bangalore has prepared a National Biomass Resource Atlas. It reports that the surplus agro, industrial and agricultural residues in the country has been estimated to about 120-150 million MT per year for power generation which has a biomass power potential of about 18000 MW.

A cumulative biomass power generation capacity of 1870 MW through 220 projects has already been installed and 2170 MW through 170 projects are under implementation as on 30.6.2009 in the States of Andhra Pradesh, Chhattisgarh, Gujarat, Haryana, Karnataka, Maharashtra, Punjab, Rajasthan, Tamil Nadu, Uttar Pradesh and West Bengal.

This information was given by Shri Farooq Abdullah, Union Minister for New and Renewable Energy, in a written reply in Rajya Sabha today.

Support for Renewable Energy Sector

The Government has taken various measures to improve overall availability of power in the country. They are, addition of generation capacity, development of Ultra Mega Power Projects, harnessing surplus captive power into the grid, strengthening and improving of sub-transmission system in States, promoting demand side management, energy efficiency and energy conservation measures, and strengthening of inter-state and inter-regional transmission capacity.

An Energy Coordination Committee chaired by the Prime Minister has been constituted in 2005 to enable a systematic approach to policy formulation, promote coordination in inter-departmental action and function as a key mechanism for providing institutional support to decision making in the area of energy planning and security.

The Government is already providing support to renewable energy sector through a mix of fiscal and financial incentives. Central Financial Assistance ranging from about 30 % to 90% of costs of various types of renewable energy systems/devices for different applications is being provided depending on the technology employed, location and user category. Fiscal incentives being provided include accelerated depreciation, nil/ concessional excise and customs duties. Further benefit under Section 80-1A of Income Tax Act 1961 is available to undertakings set up for the generation or generation and distribution of Renewable power in India. This apart, preferential tariff for grid interactive renewable power is being given in most potential States.

Accordingly, the main proposals for energy sector, which are being acted upon are as contained in the Integrated Energy Policy formulated by the Government in December 2008 covering all sources of energy including renewable.

This information was given by Shri Farooq Abdullah, Union Minister for New and Renewable Energy, in a written reply in Rajya Sabha today.

Ushdev International to expand wind power

Ushdev International Ltd is substantially expanding its wind power portfolio. The Mumbai-based wind power producer plans to set up a 9.9-mw wind farm in Theni district, Tamil Nadu, with a total investment of Rs 60.9 crore. The order for supplying six wind turbines (of 1.65 mw each) has already been placed on Vestas Wind Technology India Pvt. Ltd. The project is due to complete next month.
In a telephonic interaction with Projectmonitor, Ushdev officials said that once the new wind farm was in place, the company's total wind power capacity would increase significantly from the current 12.93 mw to 22.83 mw, with a cumulative capital investment of around Rs 125 crore. The company has its farms in Tamil Nadu, Karnataka, Gujarat and Rajasthan.
Primarily a steel trader, the 1994-formed Ushdev International diversified into power generation and trading by setting up its first project—a 2.53-mw wind farm with 11 turbines in Tamil Nadu—in 1997. Between 2005 and 2007, new capacity worth 10.4 mw was set up in Gujarat (4.8 mw), Rajasthan (2.4 mw), Karnataka (1.6 mw) and Tamil Nadu (1.6 mw). The latest addition was in May 2007 when it commissioned a 3.2-mw project at Sumana, Jamanagar district, Gujarat, with an investment of Rs 32 crore.
All the power plants are grid-connected and sell power to respective state electricity boards, officials noted. As part of its wind energy portfolio expansion, the company is looking at expanding capacity at existing locations and exploring newer states, including Maharashtra, they added.
