The Sentinel Energy Center (SEC) is located within unincorporated Riverside County.
SEC is a nominally rated 850-megawatt natural gas-fired, simple-cycle facility consisting of eight natural gas-fired General Electric LMS100 combustion turbine generators, selective catalytic reduction and carbon monoxide equipment, and a zero liquid discharge system. Other facilities within the project are a 3,200ft-long potable water supply line, a 0.75-acre stormwater retention basin, and five on-site water supply wells. A 2.6-mile-long natural gas pipeline starting from the existing Wildflower Indigo Energy Facility to the plant is also part of the project.
SEC supplies quick-start peaking capacity, energy, and ancillary services into the California Independent System Operator's Los Angeles Basin Local Capacity Requirement (LCR) Area. The LCR area needs additional peaking capacity to meet resource adequacy requirements and ensure grid reliability. SEC’s capacity, energy, and ancillary services are sold under long-term contract to one or more load serving entities and has a power purchase agreement with Southern California Edison for five of the units.
Power Plant Certification and Exemption Processes
As required by the Warren-Alquist Act, the Energy Commission monitors Commission-certified energy projects throughout construction, operation, and closure to ensure compliance with the conditions of certification imposed by the Commission’s Final Decision for approving the projects.
