Suzlon secures repeat US order

                             Horizon Wind orders further 200 MW for 2009

Pune/Chicago - Suzlon Wind Energy Corporation (SWECO), a step-down subsidiary of Suzlon
Energy Limited, India, announced the signing of a repeat order with Horizon Wind Energy for
200 MW of wind turbine capacity.

Horizon Wind Energy, based in Houston, Texas, is one of the largest wind power developers in
the United States and is owned by the Portuguese utility EDP (Energias de Portugal, S.A.).
The original contract calls for delivery of 400 MW of turbine capacity in 2008 and 2009, and now
has been expanded to include an additional 200 MW in 2009. The capacity will be supplied in
Suzlon’s S88-2.1 MW wind turbine and will be delivered to various ready-to-build sites across
the country.

The turbine agreement includes the supply of 95 units of the S88-2.1 MW in 2008 and 190 units
in 2009. Suzlon is also contracted for operations, maintenance and service of the wind turbines
for two years and an option for five.

“This order reinforces the trend for renewable energy and wind in the United States. Despite
economic slowdown, new wind installations more than doubled in 2007 from 2006. With growth
drivers like Renewable Portfolio Standards, and the US actively pursuing domestic resources of
energy security - we see a strong, promising market going forward,” Andre Horbach – CEO,
Suzlon Group stated.

The United States registered over 45% growth in 2006-07, and an average growth rate of over
35% over a three year period according to the World Market Update 2007 report published BTM
Consult ApS. The United States also ranked as the world’s largest market in 2007 comprising
26.5% of the global market and 5,244 MW of new capacity installed. The market is forecast to
add 6,500 MW in 2008, and a cumulative 43,500 MW between 2008 and 2012.

 “This is an important order demonstrating Suzlon’s position in the US market and showing
confidence in our people, product and company. The health of the world’s economy depends on
power. With the price of oil setting new records above USD 100-a-barrel, utilities and industries
looking to hedge power costs and with global warming threatening to impact the global economy
nations are all looking to wind energy in a big way. We see continued high growth for Suzlon
and sector at large,” said Tulsi R Tanti – Chairman and Managing Director, Suzlon Energy
