Roseville Energy Park (REP) is located in the City of Roseville, Placer County. REP is within the limits of the City of Roseville, adjacent to and north of the Pleasant Grove Waste Water Treatment Plant. The REP site is owned by the City of Roseville. Surrounding land uses currently include ranching (agricultural grazing) and rural residential.
The REP is a nominal 160-megawatt (MW) natural gas-fired, combined-cycle electrical generating facility consisting of two Siemens SGT-800 combustion turbine-generators (CTGs), two heat recovery steam generators (HRSGs) with duct burners, selective catalytic reduction (SCR) and oxidation catalyst equipment to control NOx and carbon monoxide (CO) emissions, respectively, a single condensing steam turbine generator (STG), a de-aerating surface condenser, and a mechanical draft cooling tower using reclaimed water for cooling.
REP is rated at a nominal net generating capacity of 120 to 125 megawatts (MW), with the ability to peak-fire to 160 MW nominal during summer design conditions.
On March 24, 2021, California Energy Commission staff approved the installation of Siemens A+ turbine upgrade package (A+ Turbine Upgrade) for both combustion turbines, and addition of piezo-actuated valves for each burner to allow for a more stable combustion process and a more balanced combustion spread. The purpose of the A+ Turbine Upgrade was to increase the gross output of each turbine 2.5 MW.
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.
