Operating Asset will Position Middle River Power to Unlock Additional Flexible Capacity in California upon Closing
Chicago, IL., Feb. 12, 2026 – Middle River Power has entered into an agreement to acquire a 50% ownership interest in the Midway-Sunset Cogeneration Company, an operating power plant in Kern County, California. The facility is an approximately 234-megawatt natural gas-fired peaking facility that has long served as a reliable source of dispatchable power in California.
The acquisition further expands Middle River Power’s substantial operating asset footprint across California, which includes 1,800-megawatts of thermal generation and 380-megawatts battery energy storage systems (BESS). Middle River Power remains a leader in California’s energy transition, with approximately 2.5 gigawatt-hours of co-located and standalone BESS across nine thermal generating facilities statewide. These investments have reduced gas utilization, supported grid reliability, and delivered clean capacity where it is needed most.
Middle River Power is looking forward to expanding its cooperative relationship with California Resources Corporation (CRC) as future co-owners of Midway-Sunset. The companies will collaborate to evaluate the potential integration of BESS at the facility as they continue to work together to provide decarbonized power solutions to support California’s broader decarbonization goals. “We’re pleased to have the opportunity to add Midway-Sunset to Middle River Power’s operating portfolio,” said Mark Kubow, Chief Executive Officer of Middle River Power. “This facility has played an important role in California’s power system, and we see an opportunity to apply our experience integrating energy storage and optimizing dispatch to support the state’s clean energy transition while maintaining reliability.” With this acquisition, Middle River Power will continue to execute on its strategy of investing in essential, operating power infrastructure while thoughtfully evaluating opportunities to modernize assets and support California’s evolving grid needs.
