Power Sustainable Energy Infrastructure Inc. (PSEI) is investing in North American solar with the acquisition of a 50% stake in EDF Renewables North America’s Desert Quartzite Solar+Storage Project in Riverside County, California.

The investment is PSEI’s largest to date and was executed with Potentia Renewables Inc., PSEI’s integrated developer and asset manager.

Desert Quartzite is under construction for a capacity of 300 megawatts (MW) of solar generation and a battery energy storage system with a capacity of 150 MW every four hours. Construction is expected to be finished by the end of the year, and with the commencement of commercial operation the final phase of PSEI’s investment will close.

EDF Renewable’s asset optimization team will continue the project’s long-term operations and maintenance.

Clean Power Alliance has a 20-year power purchase agreement for the electricity generated at Desert Quartzite to service Los Angeles and Ventura counties.
