The northeast monsoon, commonly known as winter monsoon mostly benefits Tamil Nadu , whereas southwest monsoon , known as summer monsoon blows from sea to land ensuring sufficient wind speeds in the southern and western regions of the country. The southwest monsoon is predominant and majority of the wind power generation in the range of 65-90 per cent of the annual yield takes place during these months. From January to May wind availability drops resulting in less power generation. The foundation stone to harness renewable energy sources was first laid in India in the year 1982 with the establishment of the Department of Non-conventional Energy Sources (ONES) , in the 0.333 0.106 0.076 0.122 1.650 2.104 2.988 2.881 4.181 15.077 1.723 2.895 2.825 3.279 16.303 0.000 0.065 0.065 0.070 0.246 0.003 0.082 0.090 0.130 0.775 2.207 2.779 2.692 3.296 17.931 0.758 1.127 1.387 2.420 7.826 6.206 8.146 8.720 9.855 59.675 then Ministry of Energy. The Department had the responsibility of formulating policies and programmes for development of new and renewable energy apart from coord inating and intensifying R&D in the sector. In 1992, ONES became the Ministry of Non-conventional Energy Sources (MNES). And in October 2006, the Ministry was re-christened as the Ministry of New and Renewable Energy (MNRE). During the period from 2002 to 201 2, the growth momentum in the Indian wind energy sector picked up. The pace of development was marked by formulation of right regulatory framework, incentive mechanism, flourishing component manufactu ring industry, emergence of local players and coming in of multinational companies as well as technology advancement. During this period India saw massive addition in its wind power capacity (Table 2) .
