The Ministry has undertaken an intensive exercise during the year to review its programmes through various working groups set up for preparation of the 12th Plan. The Ministry is envisaging a capacity addition of about 30,000 MW from renewable during the 12th Plan.
Major Achievements in 2011
The Year 2011 has seen a significant growth with a number of new initiatives in the renewable energy sector. The wind energy sector picked up momentum again by adding over 2800 MW capacity resulting in grid-connected renewable power capacity crossed the 22,000 MW milestone which is about 11% of the total power generation capacity of the country. During the year grid-connected solar power plants crossing the 100 MW milestone. In fact, SPV power plants of over 180 MW were set up in the country. Over 1000 remote villages were electrified through renewable energy systems during this year. Over 50 MW off-grid installations were completed. Another initiative of the Ministry was to launch a comprehensive project to popularize renewable energy systems in the Ladakh
Jawaharlal Nehru National Solar Mission
The Mission aims at adding 20,000 MW solar power capacity in the country by 2022. Implementation of the Phase – I of the Mission started during the year. One of the target areas is promotion of grid-connected solar power in a big way with the objective to bring cost of solar power generation to grid parity levels. In this year 180 MW of grid-connected solar power projects have been commissioned in the country and this figure will cross 400 MW by the end of this financial year. Projects totaling 350 MW have been allotted in batch-II of phase–I in December,2011 through competitive bidding. The tariff quoted are amongst lowest tariffs anywhere in the World with an average Rs.8.77 per kWh and a bid lowest of Rs.7.49 per kWh. If compared with the tariffs of over Rs.18 per kWh at the start of the Mission, this is a reduction of more than 50%.
The Ministry is giving special focus on research in solar energy. 36 R&D projects in solar thermal and photovoltaic technologies are under implementation. A Centre for Solar Thermal Research has been set up at IIT Rajasthan, Jodhpur. Under R&D Projects sponsored to industries in public-private partnership mode, a 30 ton Solar air conditioning system using concentrating solar power parabolic troughs and triple effect vapor absorption machine has been developed and demonstrated at Solar Energy Centre, MNRE. It is a stand-alone system for day time use and can take care of intermittent clouds through small storage.
The system once tested for its satisfactory performance, could be useful for offices and institutions working during day time when solar radiation is also available. In another project, a State of the Art fully automatically tracked paraboloid dish of 90 sq. m. area has also been developed and demonstrated at Solar Energy Centre. The dish is expected to find good opportunity in industries for processed heat applications as it is installed on a pillar and the space below dish could be utilized for other purposes.

A capacity addition of 3815 MW have been achieved during 2011 from various renewable energy sources. This includes 2827 MW from wind power, 310 MW from small hydro, 498 MW from biomass and 180 MW from solar energy. With this, the total installed capacity from renewable has reached 22,447 MW.
Wind energy is the fastest growing renewable energy option today. A total capacity of 15,880 MW of wind power has been installed in the country. The progress during the current year has been very good. A capacity of around 2827 MW has been installed during the year. It is expected that it will touch around 3500 MW upto March,2012. It would be a significant improvement as compared to figures of 1485, 1565 and 2350 MW in 2008-09, 2009-10, 2010-11 respectively. As per the recommendations of Working Group for 12th Plan, a target of 15,000 MW has been proposed for 12th Plan.
The Small hydro power programme in India is now by and large private investment driven. 24 States have announced their policies to invite private sector to set up SHP projects. Since SHP projects have reasonably good economic viability, a number of financial institutions and banks are ready to finance these projects. Accordingly, a major part of capacity addition and exploitation of SHP potential in future is expected from private sector projects. With a capacity addition of 310 MW during 2011, the total installed capacity from SHP projects is 3210 MW. The Ministry is also focusing on developing micro hydel projects and watermills for electrification of remote areas. As per the recommendations of Working Group for 12th Plan, a target of 2,100 MW has been proposed for 12th Plan.
The Biomass Power and Bagasse Co-generation Programme is implemented with the main objective of promoting technologies for optimum use of country’s biomass resources for grid power generation and maximizing power generation from bagasse produced in sugar mills. During 2011 a capacity of 498 MW have been added. The cumulative biomass power/bagasse cogeneration based power capacity has reached 3056 MW. During the year the Ministry has continued the existing scheme with two modification related to (a) Cogeneration projects through Build, Own, Operate, Transfer (BOOT) model in cooperative sugar mill (b) Boiler upgradation of cogeneration projects in cooperative sugar mills. A target of 2600 MW is proposed for the 12th Plan period.

Solar Energy Centre of the Ministry in collaboration with the Ministry of External Affairs has been providing training to participants from different developing countries.
Renewable Energy and Climate Change:
Renewable energy is central to climate change mitigation efforts. Broad estimates indicate that mitigation from existing renewable energy portfolio is equivalent to around 4-5% of total energy related emissions in the country. Further, the vast market potential and well-developed industrial, financing and business infrastructure, has made India a favorable destination for Clean Development Mechanism (CDM) projects, with renewable energy projects having the major share. National renewable energy plans offer ample opportunity for CDM projects and technological innovations.
India had 727 registered CDM projects, which is around 21% of worldwide registered projects. With 520 projects, renewable constitute around 72% Indian CDM registered projects. Within renewable, wind has the maximum number of 225 projects followed by hydro 82 and 6 for solar energy.
