Service and maintenance for remaining estimated lifecycle of wind turbines ----- Signals growing confidence in Siemens' long-term programs as wind energy industry matures in the region

Siemens has signed 15-year contract extensions with RES Americas to continue providing service and maintenance at two wind projects in North America. Siemens will provide long-term service for the 26 SWT-2.3-93 wind turbines operating at RES Americas' Whirlwind Energy Center. Long-term service will also be provided by Siemens for the 72 SWT-2.3-93 units in operation at RES Americas' Hackberry Wind Farm. Both projects are located in Texas, U.S.A. This is Siemens' first wind service contract signed with a duration of 15 years in North America.

Siemens currently has an existing five-year agreement with RES Americas for both sites. Under the new agreements, Siemens will provide 15 additional years of service, maintenance, and warranty along with an availability guarantee. The extensions will help both projects perform at high levels of efficiency and availability for years to come, and most notably, over the entire estimated 20-year lifecycle of the units. Siemens' advanced remote monitoring and diagnostics are included along with the company's Advanced Grid Performance (AGP) upgrade at both sites. Siemens' AGP upgrade comprises a series of tailored solutions that enable the wind park operator to comply with constantly evolving grid requirements.

With a combined output of approximately 226 megawatts (MW), the Whirlwind and Hackberry wind projects, located in West Texas, produce enough electricity to power an estimated 68,000 Texas households annually.

"As the wind energy industry continues to mature in North America, it is essential that our customers continue to receive high levels of availability, efficiency and energy output from their assets, particularly as the turbines move into their post warranty years," said Tim Holt, CEO, Service Renewables, Energy Service Division, Siemens Energy. "This is where Siemens' long-term programs can provide the greatest benefit, by providing cost-effective, innovative service and preventive maintenance for the entire estimated lifespan of these assets. We look forward to continuing our relationship with RES Americas as their service provider for these important renewable energy projects, which provide clean energy to residents across Texas."

Wind power and wind power service are part of Siemens' Environmental Portfolio. In fiscal 2012, revenue from the Portfolio totaled about €33 billion, making Siemens one of the world's largest suppliers of ecofriendly technologies. In the same period, our products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by more than 330 million tons, an amount equal to the total annual CO2 emissions of Berlin, Delhi, Hong Kong, Istanbul, London, New York, Singapore and Tokyo.

The Siemens Energy Sector is the world's leading supplier of a broad spectrum of products, services and solutions for power generation in thermal power plants and using renewables, power transmission in grids and for the extraction, processing and transport of oil and gas. In fiscal 2012 (ended September 30), the Energy Sector had revenues of EUR27.5 billion and received new orders totaling approximately EUR26.9 billion and posted a profit of EUR2.2 billion.
