Southern Power announces further expansion of Millers Branch Solar Facility in Texas

ATLANTA, Nov. 21, 2024 /PRNewswire/ -- Southern Power, a leading U.S. wholesale energy provider and subsidiary of Southern Company, today announced an additional expansion of its 29th solar project — Millers Branch Solar Facility. The Phase III expansion will account for an added 132-megawatts (MW) from the previous Phase I and Phase II expansion of 200 MW and 180 MW respectively. This final development will bring the Millers Branch Solar Facility to a total generating capacity of 512 MW.

"This expansion of the Millers Branch Solar Facility represents the final phase of construction at the facility," said Southern Power President Robin Boren. "The completion of this work will bring the facility's total generating capacity to 512 MW, making Millers Branch our largest solar facility to date and significantly enhancing Southern Power's ability to deliver clean energy on a larger scale. This project is just the latest testament of our longstanding commitment to building the future of energy and providing for the renewable energy needs of our customers and communities."

The project, located in Haskell County, Texas, contributes to the company's growing renewable fleet of clean generating assets from California to Maine. Southern Power will lead the continued development and construction of all phases of Millers Branch. Phase III is expected to achieve commercial operation in the fourth quarter of 2026.

Southern Power signed power purchase agreements with Synopsys, Inc and Keysight Technologies for environmental attributes, such as renewable energy credits (RECs), produced under their respective shares of the Millers Branch Solar Facility. Sustainability Roundtable, Inc. supported the power purchase agreement for Synopsys, the anchor tenant. 

With the addition of Millers Branch Phase III, Southern Power's solar portfolio consists of more than 3,050 MW of solar generation currently operating or under construction. Southern Power's solar facilities are a part of the company's 5,590 MW renewable fleet, which consists of 30 solar and 15 wind facilities currently operating or under construction.
