Integration of renewable energy into India's power system was a key theme of a media conference in Delhi in November. Focusing on wind power, Ministry of Non Conventional Energy Sources (MNES) secretary P.M. Nair called on the media to help create awareness. "In the long term, modern biomass and solar energy, principally through the photovoltaics route will dominate. However, in the near term, wind energy will be more economic as this technology is already commercially competitive in some areas." Total wind capacity in India up to September 2001 has reached 1425.7 MW. Of this, 85.9 MW was installed since April, with 9.8 MW going up in Karnataka, 50 MW in Maharashtra, 6.7 MW in Rajasthan, 18.9 MW in Tamil Nadu and 0.5 MW in West Bengal. With the exception of the West Bengal aided project in Fraiserbad, the rest were all private sector developments. An additional 200 MW is expected by the end of March. Over 3165 MW of renewables capacity has been installed in India according to Nair, still a long way from the government's 10% renewables by 2012 target, about 10,000 MW. Of this, 50% is expected to come from wind. Nair said a rough estimate for investment in the renewables sector so far is $6374 million, with 79% coming from the private sector, 17% from the government and the balance from external financial assistance. Major constraints, include lack of a favourable power purchase policy, fiscal incentives and inadequate budgetary support. Nair added: "The development of the sector demands a legislative framework."
