Suzlon announces 400 MW deal with Horizon Wind

             Suzlon expands its international clout with newest client

Pune/Chicago - Suzlon Wind Energy Corporation, the US-based subsidiary of Suzlon
Energy A/S of Denmark, has signed a contract for a 400 MW of wind turbine capacity
with Horizon Wind of Houston, Texas, one of the largest wind power developers in the
United States and also owned by Portuguese utility EDP (Energias de Portugal, S.A.), a
leading renewable energy developer in the world. The contract calls for delivery of 200
MW of turbine capacity in 2008 and another 200 MW of capacity in 2009.

“Suzlon is excited to embark on a new partnership with a significant contract to deliver
400 megawatt of Suzlon turbines for Horizon Wind,” said Andris Cukurs, CEO of Suzlon
Wind Energy Corporation of Chicago, Ill. “Horizon is a fast-growing company that is
backed by the well-established EDP of Portugal, and we are exceptionally pleased to
team with such respected international companies.”

“The wind power market is becoming less segmented, as it quickly transitions into a
truly global business with transactions occurring across continents all the time,” said
Andre Horbach, CEO of Suzlon Group based in Amsterdam. “Suzlon’s global structure
and vertical integration strategy complement this dynamic shift, so we believe the
company is well-structured to help Horizon Wind reach its goals in the U.S.”

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 in Horizon’s large project pipeline.

According to António Mexia, EDP’s Executive President “this agreement will further
strengthen EDP’s capacity to accomplish the ambitious plan established for the coming
years. In addition, our turbine needs will be practically satisfied until the end of 2009.”
Mexia recognizes that “this new relationship with Suzlon enlarges EDP’s worldwide
supplier portfolio. We are really looking forward to working with this partner.”

Horizon Wind Energy is part of the EDP group of companies, a world leader in renewable
energy with more than 1700 gross MW of renewable power capacity.

The turbine agreement includes the supply of 95 units of the S88-2.1 MW in 2008 and
95 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 demand.
