Southern Power acquires Glass Sands Wind Facility

Southern Power, a leading U.S. wholesale energy provider and subsidiary of Southern Company, today (April 20) announced the acquisition of its 15th wind project the 118-megawatt (MW) Glass Sands Wind Facility from Steelhead Americas, Vestas' development arm in North America.

"We are proud to announce this new addition to our generation portfolio," said Southern Power President Bill Grantham. "Glass Sands is a great project for Southern Power as we continue to provide clean renewable energy resources to meet the needs of our customers."

The project, located in Murray County, Oklahoma, is Southern Power's fifth wind facility in the state and contributes to the company's growing fleet of clean energy resources from California to Maine. Glass Sands was developed by Steelhead Americas and is expected to utilize 28 wind turbines manufactured by Vestas. Construction, executed by Mortensen, is underway, and the project is expected to achieve commercial operation in the fourth quarter of this year.

Once operational, the electricity and associated renewable energy credits generated by the facility will be sold under a power purchase agreement with Amazon. 

With the addition of Glass Sands, Southern Power's wind portfolio consists of more than 2,533 MW of wind generation. Southern Power's wind facilities are a part of the company's 4,928-MW renewable fleet, which consists of 43 solar and wind facilities operating or under construction.

This project aligns with Southern Power's overall business strategy of strengthening its wholesale business by acquiring and developing generating assets that are covered by long-term contracts with counterparties with strong credit support.
