India will witness its weakest wind energy capacity addition in seven years, due to the double-whammy of high interest rates prevailing in financial year 2012-13, coupled with a rollback of incentives, sector players and experts said.

The country may be able to add only 1,500 MW of new wind energy capacity in the fiscal year 2012-13, missing the target of 2,500 MW set at the beginning of the year. According to data from Central Electricity Authority, India has added about 1,068 MW of new wind energy capacity in FY13, until December.
