India is building a massive, floating solar power plant (Science Alert)

India will install a 50 megawatt solar power plant on a 1.27 million square metre floating platform by the end of the year.

Having already started on their plan to install 10 megawatt (MW) solar plants on top of several canals, India has taken the creative use of space one step further and is planning on floating a power station on one of the large stretches of water in Kerala, a state in south-western India.

This floating solar power technology was developed by India's Renewable Energy College and the plant is being built by Indian energy company, the National Hydro Power Corporation (NHPC). The first plant is scheduled to be commissioned in October this year.

“The ecology of the water body is not likely to be affected much and it will also reduce evaporation, thus helping preserve water levels during extreme summer. Solar panels installed on land face reduction of yield as the ground heats up. When such panels are installed on a floating platform, the heating problem is solved to a great extent. This isn’t an ideal solution, it’s not as though we can go and cover the world’s oceans with photovoltaic cells, but it’s certainly a solid intermediary step until we get those space-based solar farms up and running.”


India's Largest Solar Power Plant Planned in Madhya Pradesh -The New Indian Express

: Plans are afoot to set up the country's largest ultra mega solar power plant (UMSPP) in Madhya Pradesh's Rewa district, a senior official said today.

The plant, to produce 700 MW of electricity, would require an investment of Rs 4,000 crore, State's Additional Chief Secretary for New and Renewable Energy S R Mohanty said.
The electricity from the plant would be available at Rs 5.40 paise per unit, which would be the lowest in the country, Mohanty said.

The state government would set up the plant as a joint venture with the Ministry of New and Renewable Energy, Power Grip Corporation and the Solar Energy Corporation of India, he said.

Thirteen hectares of land spread over four villages of Barseta, Ramnagar, Latar and Badwaar has been chosen for locating the plant in Gurh tehsil of Rewa, which is the home district of state Energy Minister Rajendra Shukla.

The country's biggest solar plant with a capacity of 130 MW is situated in Neemuch district of the state.

Minister of State for Renewable Energy Piyush Goyal told Lok Sabha last week that the government is promoting generation of renewable energy by providing various fiscal and financial incentives such as capital and interest subsidy, concessional excise and customs duties to encourage Indian and foreign investors to invest in new renewable energy sector.

"Ultra mega solar power projects have been planned in Rajasthan, Gujarat, Madhya Pradesh and Jammu and Kashmir. The capacity will depend upon availability of land. On an average 1 MW of solar photovoltaic power project generates about 1.6 million units of electricity per annum," he said during Question Hour.

BHEL signs MoU for setting up an Ultra Mega Solar Power Project at Sambhar in Rajasthan

Bharat Heavy Electricals Limited (BHEL), Solar Energy Corporation of India (SECI), Sambhar Salts Limited (SSL), Power Grid Corporation of India Limited (POWERGRID), Sutlej JalVidyut Nigam Limited (SJVNL) and Rajasthan Electronics and Instruments Limited (REIL) have signed a Memorandum of Understanding (MoU) on 29th January 2014 for formation of a Joint Venture Company (JVC) for setting up of a Ultra Mega Solar Power Project (UMSPP) with a cumulative capacity of 4,000 MW in phases at Sambhar in Rajasthan on build, own and operate basis.

The planned first phase implementation of the UMSPP at Sambhar is of 1,000 MW, and the balance 3,000 MW in subsequent phases. This is an initiative of Ministry of Heavy Industries and Public Industries (HI&PE), Ministry of New & Renewable Energy (MNRE) and Ministry of Power (MoP).

The main salient features of the MoU are as follows:

• The proposed equity participation in the JVC is: BHEL - 26%, SECI - 23%, SSL - 16%, POWERGRID - 16%, SJVNL - 16%, and REIL - 3%.

• The JVC will be incorporated in Delhi / National Capital Region (NCR) after finalization of Definitive documents.

• The JVC will be under the supervision of Ministry of HI&PE.

• The JVC shall arrange the entire debt requirement for implementation of various projects.

• The JVC shall apply for connectivity, long term/ medium term/ short term open access as per relevant regulations for evacuation and transfer of power.

• The JVC shall create and construct the requisite infrastructure for implementation of the Project. • BHEL will supply the photo-voltaic (PV) modules for the first phase (i.e. 1,000 MW) and will also have the right of first refusal for cells and modules for subsequent phases (i.e. 3,000 MW) of the project at Sambhar and other projects, SECI will sign the power purchase agreement (PPA), SSL will provide the land with all clearances, POWERGRID will evacuate power, SJVNL will assist in Project management, and REIL will do the operation & maintenance (O&M).

All modules required during the Phase-I implementation (i.e. 1,000 MW) of the project at Sambhar will be for supply by BHEL on nomination basis subject to the manufacturing capacity of BHEL at that point of time. Besides, BHEL will also have the right of first refusal for supply of solar PV cells and modules during the subsequent phases (i.e. 3,000 MW) of the project, and other projects developed by the JVC.

The project is likely to be completed by 7 to 8 years from the date of all the approvals & clearances.

This information was given today by Minister of State in the Ministry of Heavy Industries and Public Enterprises, Shri Pon. Radhakrishnan in a written reply to Lok Sabha question.

Installing them on sea is a good idea as land is a very scare resource.

It will be something like this one in Japan

Sea water and wind from the sea is EXTREMELY corrosive. Not to mention the engineering difficulties in constructing it.

I suspect the construction cost and maintenance cost will make it infeasible.

Unlike this Japanese plant, the Indian one will be a floating plant. Not sure if its on fresh or sea water

The image is of panel on fresh water.

When objects float on sea water a thick layer of salts starts depositing on it. It will eat away everything and damage everything in no time.

why not over railway tracks,, we got over 1 lakh km of track length,, no acquisition issues., no cost of land,, electricity could be provided to areas along the track ,, so lots of savings on transmission cost and maintenance of transmission system,

Transmission loss.

However we can certainly put up panels on Railway stations and make them self sufficient.
 
. .
why transmission loss when panels will be used to provide electricity along the tracks,, it will do away with the need of feeding the grid in itself

Electrical power is equal to voltage times current, the relatively low voltages in a DC system imply relatively high currents. Minimizing resistive losses requires thick, short supply cables and closely spaced converter stations. Solar panel cannot do this.

However they can run low power electronics on trains and on the railway stations.

Think of it as trying to run an ship on a river.
