VICTORIA, Texas [April 10, 2026] – South Texas Electric Cooperative, Inc. (STEC) today announced it has closed the acquisition of two existing natural gas-fired generation facilities, a strategic investment that expands its energy portfolio, which serves 47 Central and South Texas counties.
The assets are being acquired for $768 million from PROENERGY. The acquisition follows several years of deliberate planning and positions STEC to continue to meet rising electricity demand across the state. These quick-start units are dispatchable, reliable assets that will provide on-demand power.
The assets will add 768 MW of capacity to the STEC portfolio and include:
- The 384 MW Braes Bayou Power Plant in Fort Bend County, with commercial operation achieved in June 2022; and
- The 384 MW Brotman Power Plant in Brazoria County, with commercial operation achieved in May 2023.
“Acquiring these two natural gas-fired power plants is a strategic step that reinforces STEC’s role as a dependable provider of reliable energy,” said Barbara S. Miller, President of the STEC Board of Directors. “As Texas experiences unprecedented load growth – driven by rapid population gains, expanding industrial activity and the rise of AI and data centers – this investment ensures we are well-positioned to support both the grid and the Central and South Texas communities we serve.”
Under the terms of the agreements between the parties, PROENERGY will continue to staff, operate and maintain the assets to ensure continuity, safety and operational excellence. The assets are powered by PROENERGY-manufactured equipment, including PE6000 turbines. STEC does not anticipate any positions to be eliminated post-closing.
The addition of these assets enhances STEC’s flexible, dispatchable generation capacity within the Electric Reliability Council of Texas, Inc. (ERCOT) market, strengthening its ability to deliver reliable power during periods of peak demand and to provide ancillary services to meet the needs of the ERCOT energy-only market. By acquiring operational facilities, STEC also avoids the development and construction risks associated with new-build generation in an environment that is increasingly competitive for long-lead time equipment for power generation.
“This acquisition represents the culmination of more than five years of strategic planning with our Board of Directors to best position STEC to continue to meet the needs of our member cooperatives and the ERCOT market,” said Clif Lange, General Manager of South Texas Electric Cooperative. “This transaction strengthens our already robust power supply portfolio, and advances our commitment to delivering affordable, reliable energy to our member cooperatives.” STEC was advised in the transaction by counsel Orrick, Herrington & Sutcliffe and PROENERGY by Latham & Watkins.
