Siemens will supply 95 units of the SWT-2.3-101 wind turbine, and three SWT-3.0-101, Siemens’ gearless direct drive wind turbine, which was recently launched for sale in America.

Construction of the wind farm is scheduled for late August, with the first wind turbines being delivered in April, 2011.

The Crossroads wind power project will be built in Dewey County in northwest Oklahoma, approximately 160 km (100 miles) from Oklahoma City.

Siemens will deliver, install and commission the wind turbines and provide wind turbine service and maintenance for an initial period of three and one-half years.

The wind farm is set to be completed in the second half of 2011.

Jens-Peter Saul, CEO of the Siemens Wind Power Business Unit, says: “This is the first time that the new SWT-3.0-101 direct drive turbine has been sold in the US. Bringing our new generation of direct drive wind turbines to Oklahoma is the first step in establishing this game-changing technology in North America.”
