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.

3.6 MW Power from Poultry Litter in Andhrapradesh

for the sake of who don't understand telugu,

Raus Power limited established a Power plant in East Goadavari district(Andhrapradesh) to produce power from Poultry Litter(dried) and Rice husk.As per the Plant incharge Mr. Sridhar,

  • It's been in operation for the last 4 months
  • To operate this plant, daily 120 Tonnes of Litter and 50 tons husk are required.
  • To dry the litter , special boilers are used.
  • To avoid of the risk of nonavilability in rainy season, 600 ton capacity godown is constructed.
  • To do away with pollution, EPC(electrostatic precipitator) is being used.
  • Waste from the plant is being used in brick manufacturing and laying the roads.
  • The reason why this place was choosen is, near by poultry farms capacity is more than 8 Million (Guess it is almost 40% of total State)
  • Local farm owners are happy as it is no more issue to get rid the litter

Media says, apart from this place, Chittor(Famous temple town Tirupati is located in this district) also equal potential place for the same.

India Aims for 20,000 Megawatts of Solar Power Capacity by 2020

Researched by Industrial Info Resources (Sugar Land, Texas)
The Indian government is reported to have finalized the draft for the National Solar Mission, outlining ambitious long-term plans to attain an installed solar power generation capacity of 20,000 MW by the year 2020, which would be increased to 100,000 MW by the year 2030, and further to 200,000 MW by the year 2050.

The plan also aims to reduce the cost of solar power generation to between $0.0846 and $0.1058 per kilowatt-hour (kWh) by 2017-20 in order to make solar power competitive with power generated from fossil fuels.

In order to achieve the proposed targets, the government is likely to make investments of approximately $18 billion to $22 billion over a period of 30 years. An estimated investment of about $1.06 billion-$1.27 billion will be required during the current Eleventh Five-Year Plan period, 2007-12, while an investment of $2.54 billion-$3.18 billion will be required during the Twelfth Five-Year Plan, 2012-17.

The Mission envisages 20,000 MW of solar power generation capacity to be installed across five application segments by 2020. These segments include 12,000 MW of power connected to the utility grid, 3,000 MW of power from 1 million captive and grid-connected rooftop solar photovoltaic (PV) installations with an average individual capacity of 3 kilowatts (kW) each, 3,000 MW of rural installations, and 2,000 MW of distributed solar PV applications such as telecom towers. In addition, about 20 million households are envisaged to have access to solar lighting, while solar heating applications would be set up over 20 million square meters of collector area by 2020.

The plans are proposed to be implemented in three phases during 2009-2020. The first phase will focus on achieving economies of scale and validating the economic and technological viability of different solar applications. Some of the plans to be implemented during this phase include promotion of large-scale solar utility plants, and mandatory deployment of onsite or rooftop PV applications in buildings and establishments owned by the government and public sector undertakings to achieve a target of 100 MW through this initiative by 2012.

The government also plans to mandate installation of solar power generation capacity of at least 5 percent of the total installed capacity of upcoming thermal power plants based on oil, gas and coal. Further, vacant land available in existing power plants would be used for setting up solar power units.

Solar applications are planned to replace diesel generators to meet peak daytime power requirements. Solar PV panels will be used to charge inverter systems in residential and commercial establishments.

The government also plans to develop two or three large-scale concentrating solar power (CSP) plants with capacities of 50 MW, 100 MW with storage, and a 150-200-MW solar/gas hybrid model, to demonstrate economic and technological feasibility. Pilot projects will be undertaken for large-scale rural electrification based on solar power.

Solar lighting systems will be promoted in rural and urban sectors through micro-financing business models to provide access to lighting for 3 million households by 2012. The government is expected to invest up to $254 million in this initiative.

There will also be a focus on the promotion of solar heating systems, for which the target has been set at 7 million square meters of solar heating applications by 2012. The government plans to mandate installation of solar water heaters in functional buildings such as hotels, hospitals and guesthouses, subject to availability of at least 500 square meters of land area.

The first phase of the Mission would also see the establishment of technology parks to promote local manufacturing capacities. This target has been set at 1,000-1,500 MW of manufacturing capacity by 2012-13.

In the second phase of implementation, during the period 2012-17, the plan is to achieve 6,000-7,000 MW of installed solar power generation capacity by 2017. This would be accomplished by scaling up validated applications with focus on grid-tied installations, implementation of validated business models for rural electrification, commercial deployment of solar thermal power projects with storage capabilities, and pilot deployment of advanced technologies such as CSP, thin film applications, storage systems and dish/Stirling systems.

In the third phase, during the period 2017-20, the target is to achieve an installed capacity of 20,000 MW by 2020 and attain tariff parity between solar power and conventional grid power. This phase would see commercial deployment of storage technologies and other advanced technologies indigenously developed through research and development. The Mission envisages the deployment of more than 1 million rooftop systems with an average capacity of 3 kilowatts by the year 2020.

In order to promote rapid and large-scale capital investments in this sector, the government is proposing to provide incentives in the form of feed-in tariffs, tax holidays up to a period of 10 years, and relief from excise duty and customs duty on critical materials and capital equipment. Similar incentives are already in place for projects in the infrastructure and information technology sectors.

Feed-in tariffs would be determined through a market-based price discovery mechanism such as inviting bids for large-scale projects. The incentive would be distributed among the utility and the central and state governments, with the utility bearing a cost of $0.0741 per kWh, while the balance amount would be borne by the central and state governments in the ratio of 70:30. Costs of solar power generation are expected to decline at a rate of 7 to 9 percent per year by 2020.

India currently has a PV-module manufacturing capacity of 700 MW. However, there is no indigenous manufacturing capability for solar thermal power plants. The government intends to promote the establishment of new plants to manufacture concentrator collectors and receivers required by CSP plants.

The proposed plans to increase solar power generation capacity to 20,000 MW by 2020 are estimated to result in a reduction of 42 million tons per year of carbon-dioxide emissions. Solar lighting and heating initiatives are expected to further reduce emissions by 3 million and 15 million tons per year, respectively, by eliminating the use of kerosene and other fuels. Additionally, solar heating applications are expected to result in peak-load shaving of about 7,500 MW, free up 4,500 MW of installed power capacity that is currently used for heating applications, and save about 350 million liters per year of fuel oil. Rooftop PV systems, estimated to reach 3,000 MW by 2020, could save about 1,050 million liters per year of diesel and reduce carbon dioxide emissions by 2.36 million tons per year.
