Earlier this month, SolarIndiaOnline reported about Solar Mission plans to install 20,000MW capacity by 2020 in the story “Renewable is not an alternative anymore”.
Ministry has finalized the draft for the National Solar Mission. After the first initiative of installing generation capacity of 50MW through Solar, the ministry has now gone all the way, to make Solar a valuable option for Indian Power Industry. SolarIndiaOnline.com earlier this month announced about the plan of ministry to install solar generation capacity of 20,000MW by 2020. According to draft agreement by Ministry, the plans are to install solar generation capacity of 20,000 MW by 2020, of 1,00,000 MW by 2030 and of 2,00,000 MW by 2050.
The total expected funding from the government for the 30-year period will run to Rs. 85,000 crore to Rs. 105,000 crore. The requirement during the current Five Year Plan is estimated to be Rs. 5,000 crore to Rs. 6,000 crore. It will rise to between Rs. 12,000 crore and Rs. 15,000 crore during the 12th Five Year Plan.
The plan till 2020 will take be implemented in three phases.
The First Phase: 2009-2012: The Ministry will focus on expansion of on-going projects for urban, rural and off-grid applications. This will involve the promotion of commercial-scale solar utility plants, mandated installation of solar rooftop or on-site photo-voltaic applications in buildings and establishments of government and public sector undertakings.
In this phase, the Mission will make it mandatory for all functional buildings such as hospitals, hotels, guest houses and nursing homes to install solar water heaters. Residential complexes with a minimum plot area of 500 sq m will also be included. Expansion of solar lighting systems through market initiatives including micro-financing, in the rural and urban sectors, is expected to provide access to lighting for three million households by 2012.
The Second Phase: 2012 and 2017: Mission will focus on the commercial deployment of solar thermal power plants. This will involve storage options, and the promotion of solar lighting and heating systems on a large scale in market mode. This will be without subsidies but could include micro-financing options.
The Third Phase: 2017 and 2020: The target is to achieve tariff parity with conventional grid power and achieve an installed capacity of 20 gigawatts (Gw) by 2020. The installation of one million rooftop systems with an average capacity of 3 kilowatts (kW) by the same year is also envisaged.
The strategy will be to achieve the target along with reducing the cost of these projects. However there has been no confirmation from the ministry on this. The original may have few changes.

The Solar Mission has not concentrated on Solar Thermal Power Plants. If we are to achieve 20000 MWe, solar Thermal power plants will play an important role. However, this being an emergent technology, efforts are to be taken to invest in R&D and pilot plants. Solar Thermal plants could be Parabolic Trough Collector (most successful for large scale power generation in the range of 50 MW), Solar Tower (considered to be the cheapest among all solar applications), Solar Stirling (suitable for areas where water is scarce) and the ambitious Solar Chimney (which if implemented in small capacity of 50 kW could be easily adopted in many of the rural areas and villages for not only power generation but also employment generation)
