Wind energy major Suzlon posted a net loss of Rs.4.69 billion in the last fiscal compared to a profit of Rs.12.65 billion in the previous fiscal, the company said Monday.

The total income of the company grew 5.12 percent to Rs.74.12 billion for the year ended March 31 from Rs.70.51 billion in the previous period.

The company attributed the poor performance to the external economic environment.

'FY2008-09 has been a challenging year for all industries, and the wind sector is no exception,' said Tulsi Tanti, chairman and managing director of Suzlon Energy Limited.

The group, along with its subsidiaries, posted a net consolidated profit of Rs.2.36 billion in 2008-09, a decrease of 77.04 percent from Rs.10.3 billion for the year ended March 31, 2008.

The total income of the group stood at Rs.265.3 billion for the period under review, up from Rs.139.47 billion in the previous fiscal.
