Suzlon signs one of the largest contracts in the history of US wind power industry

Chicago/Pune: Suzlon Wind Energy Corporation, the US-based subsidiary of Suzlon
Energy A/S of Denmark, just extended its contract with PPM Energy to add 300 MW of
wind turbine capacity to become one of the largest single contracts in the history of the
company and the U.S. wind energy industry. The original agreement calls for delivery of
300 MW of turbine capacity in 2008 and 100 MW of capacity in 2009, but now has been
extended to include an additional 300 MW in 2009 for a total of 700 MW over two years.

“We’re exceptionally pleased that PPM Energy has exercised their option to bring Suzlon
and the industry a historic contract,” said Andris Cukurs, CEO of Suzlon Wind Energy
Corporation of Chicago, Illinois. “This partnership is one for the long-haul. Suzlon is
looking forward to providing PPM outstanding customer relations, optimal power
performance and a long-term commitment to the market place,” he added.

Suzlon’s S88-2.1 MW wind turbine is the featured machine of the agreement and will be
delivered to various ready-to-build sites across the US starting in the summer of 2008.

 “Suzlon has welcomed PPM Energy’s technical and engineering input and provided direct
communication lines with the leaders of the company,” said Terry Hudgens, CEO of PPM
Energy. “Suzlon continues to focus on the future of renewable energy which aligns very
well with the strategies and values of PPM Energy.”

PPM Energy is part of the IBERDROLA group of companies, the world leader in wind
power, with more than 6,500 MW of combined wind power capacity.

The turbine agreement includes the total supply of 143 units of the S88-2.1 MW in 2008
and 191 units in 2009. Suzlon is also contracted for operations, maintenance and service
of the wind turbines for two years and an option for five, and will do so by expanding its
service territory with new facilities to meet the demand.
