Southern Co. Subsidiary Buys Siemens-Powered Apex Wind Farm


Southern Power, a subsidiary of Southern Co., has purchased the 147 MW Grant Plains Wind facility from Apex Clean Energy.

Along with nearby Grant Wind and Kay Wind, Grant Plains Wind – located in Grant County, Okla. – is the third facility Southern Power has purchased from Apex.

Apex is managing construction of Grant Plains Wind and will perform asset management services for the facility upon commercial operations, which are expected in December.

Siemens is filling an order from Apex to deliver and service 64 wind turbines for the project. The Grant Wind and Kay Wind facilities also comprise Siemens towers.

“Siemens and Apex have established a great working relationship on these three Oklahoma projects, and we look forward to seeing Grant Plains cross the finish line this year,” says Mark Goodwin, president and chief operating officer of Apex.

Grant Plains Wind will feature Siemens’ SWT-2.3-108 wind turbines, which have a rotor diameter of 108 meters and a hub height of 80 meters. These turbines are part of the company’s G2 platform of onshore-geared products.

Siemens has signed a long-term service and maintenance agreement, which includes the company’s remote monitoring and diagnostic services.

The nacelles and hubs for the Grant Plains Wind facility have been assembled at Siemens’ facility in Hutchinson, Kan., and the blades have been manufactured at Siemens’ blade facility in Fort Madison, Iowa. In addition, Siemens has a 64,000-square-foot wind service distribution center in Woodward, Okla.
