Desert Quartzite solar+storage project achieves operational status

EDF Renewables North America (EDFR) and Power Sustainable Energy Infrastructure (PSEI) have announced the operational status of their Desert Quartzite solar+storage project in Riverside County, California. 

The project has a solar capacity of 375 MWdc/300 MWac and an energy storage capacity of 150 MWac/4 hours, delivering power to the Clean Power Alliance under a 20-year power purchase agreement.

Located on Federal lands managed by the Bureau of Land Management, Desert Quartzite is designed to store electricity during peak solar generation hours. 

Once fully operational, it will supply enough power to meet the annual needs of over 163,000 homes in California and offset more than 669,000 metric tonnes of carbon emissions annually.

PSEI and EDFR announced a strategic investment in August 2024, with PSEI acquiring a 50% share in the project. The final phase of the investment will be completed once the project reaches commercial operation.
