Siemens and Airtricity sign contract for major onshore wind farm in Scotland

Siemens and Airtricity, the renewable energy development division of Scottish and Southern Energy (SSE), signed a contract on the supply of wind turbines for a major onshore wind farm in Southern Scotland. The 2.3 megawatt machines will be used at the Clyde wind farm in South Lanarkshire 70 kilometers south of Glasgow which will have a total capacity of up to 350 megawatts. The wind farm will be commissioned in 2012.

“The agreement for the Clyde project once again shows the high level of confidence placed in the
proven Siemens wind turbine technology”, said Andreas Nauen, CEO of the Siemens Wind Power Business Unit. “Following our successful completion of the Scottish Whitelee wind farm earlier this summer – at 322 megawatts Europe’s largest wind farm to date – Clyde marks a new milestone for onshore wind power in Europe.”

The scope of supply for Siemens includes the delivery installation, and commissioning the wind
turbines. Siemens will also assume responsibility for operation and maintenance for an initial
period of five years. The Clyde wind farm will yield significant benefits for Scotland in terms of local value creation and jobs. The project will provide over 200 jobs during the construction phase and more than 30 jobs during its operational lifetime.

Clyde could become the largest onshore wind farm in Europe in only two years. The scale of the
Clyde wind farm reflects UK’s ambitions to become forerunner in green technologies. The British
government has set a target of 10 percent of electricity supply from renewable energy by 2010.

Wind power is an important part of Siemens’ environmental portfolio. In 2008, revenue from the
products and solutions in the Siemens’ environmental portfolio was nearly EUR19 billion. That is,
equivalent to about a quarter of Siemens’ total revenue and makes Siemens the world’s leading
provider of eco-friendly technology.

The Siemens Energy Sector is the world’s leading supplier of a complete spectrum of products, services and solutions for the generation, transmission and distribution of power and for the extraction, conversion and transport of oil and gas. In fiscal 2008 (ended September 30), the Energy Sector had revenues of approximately EUR22.6 billion and received new orders totaling approximately EUR33.4 billion and posted a profit of EUR1.4 billion. On September 30, 2008, the Energy Sector had a work force of approximately 83,500. Further information is available at: www.siemens.com/energy
