The worldwide installed capacity of wind power reached 435 GW by the end of 2015.

China (148 GW), US (74 GW) and Germany (45 GW) are ahead of India. The short gestation periods for installing wind turbines, increasing reliability and performance of wind energy machines has made wind power a favored choice for capacity addition in India.

Wind power accounts nearly 8.6% of India’s total installed power generation capacity and generated 28,604 MU in the fiscal year 2015-16 which is nearly 2.5% of total electricity generation. The capacity utilization factor is nearly 14% in fiscal year 2015-16 (15% in 2014-15). 70% of wind generation is during five months duration from May to September coinciding with Southwest monsoon duration.
