The Ministry of Non Conventional Energy Sources (MNES) is currently producing a list of approved wind technologies, based on the guidelines it has issued to the State Electricity Boards. However, the list is not binding. Meantime the wind test centre planned for construction near Madras with support from Danish aid agency, DANIDA and Denmark's wind centre at the Risø national laboratory, is approaching its final planning hurdle. A second wind test centre, in Gujarat, is also being considered under a co-operative research agreement between the TATA energy research institute of Delhi and the Dutch national laboratory, ECN. Aid is being sought from the Dutch government and ECN has prepared a business plan for the project.
