Siemens to build wind power plant in Turkey

Germany, Hamburg, October 17, 2012. The customer is Borusan EnBW Enerji, a joint venture consisting of German energy supplier EnBW and Borusan Holding from Turkey. Siemens is to deliver a total of 22 wind turbines for the Balabanli onshore wind power plant near the city of Tekirda? in the European part of the country. The scope of supply also includes a long-term service agreement. Each wind turbine has a capacity of 2.3 megawatts (MW) and a rotor diameter of 108 meters. The installed capacity of 50 MW will be sufficient to supply about 43.000 households with clean electricity.

“The Turkish wind energy market is attractive for Siemens and we expect further growth in the
future,” said Felix Ferlemann, CEO of the Wind Power Division of Siemens Energy. “The fourth
wind power order from Turkey shows that we are not only doing well in the offshore sector, but that
we are also successful in onshore wind energy.” Turkey is seeing high levels of economic and
population growth. In order to cover the country’s increasing electricity requirement and improve
the reliability of the supply, the country is relying more and more on renewable energies, and on
wind energy in particular.

Siemens is to deliver, install and commission a total of 22 wind turbines of the type SWT-2.3-108
for the Balabanli onshore project. The company will also provide service and maintenance over a
ten year period. The long-term maintenance agreement of the type SWPS-300W is the most
comprehensive service package available from Siemens, and includes a guarantee of availability
and extended warranty on major components over the entire term of the agreement.
