Through SPVP program, Southern California Edison plans to install, own and operate up to 250MW of solar generating capacity over the next five years, 75MW of which are in immediate development.

The construction sites for these installations are mainly commercial rooftops and some open parcels of land, with most sites ranging from 1MW to 3MW of generation capacity in size. Another 250MW of rooftop solar PV will be installed and operated by independent power producers with the power output being provided to SCE’s customers.

SCE has selected Satcon’s PowerGate Plus 500kW system, an utility ready solar PV inverter, which enables simplified grid interconnection and can be integrated into SCADA systems through standardized communication interfaces.

Through SPVP, SCE aim to target the untapped resource of commercial and industrial rooftop space in Edison’s service territory. The solar power plants will be directly connected to Edison’s grid as wholesale generation and will therefore not require additional construction of transmission facilities.

Mark Nelson, director of generation planning and strategy at Southern California Edison, said: “The SPVP program is an important step in California’s clean-energy future.

“Satcon is a leader in utility-scale solar. We appreciate the company’s approach to complex challenges, and we look forward to working with them on this industry-leading project.”
