Siemens is filling an order from Apex Clean Energy to deliver turbines for the 147MW Grant Plains wind farm in Oklahoma, US.

US wholesale energy supplier Southern Power acquired the project from Apex Clean Energy.

Siemens will supply 64 of its SWT-2.3-108 wind turbines, each with 2.3MW of capacity and 108m of rotor diameter.

The project is expected to begin commercial operations by the end of this year.

The wind turbines are part of Siemens’ new G2 platform for onshore geared products. Siemens claims that the new platform has been optimised to work in all conditions.

The company also says that the new platform of G2 wind turbines feature highly engineered, designed and manufactured components with high reliability and can have low operational costs that enable relatively higher return on investment.

Siemens will also provide long-term service and maintenance for the wind turbines apart from remote monitoring and diagnostics services.

Siemens Wind Power and Renewables Division Onshore Americas CEO Jacob Andersen said: “We are very pleased to receive an additional order from Apex Clean Energy to supply turbines and service in Oklahoma, strengthening the state’s national leadership in wind energy.” 

Apart from the acquisition of Grant Plains wind farm, Southern Power purchased two other developments in Oklahoma from Apex Clean, which include the 151MW Grant Wind and the 299MW Kay Wind. Siemens supplied wind turbines for both the projects.

Southern Power President and CEO Buzz Miller said: "The acquisition of the Grant Plains wind facility is an important step in strategically growing our renewable energy portfolio.

"This project aligns with our business model and underscores our commitment to developing wind generation."
