BLM announces 230-megawatt battery system now online in California

Energy Storage News:

A 230MW battery energy storage system (BESS) from NextEra Energy Resources, part of a large solar-plus-storage project, has come online in California.

The Bureau of Land Management (BLM), which manages the land on which the 94-acre project is located in Riverside County, announced the start of commercial operations on the Desert Sunlight Battery Energy Storage System yesterday (16 August).

The 230MW BESS project adjoins the existing Desert Sunlight Solar Farm and will store renewable energy generated by the Farm and shift it to peak demand hours.

In a document approving the project in November last year, BLM said the project developer was Sunlight Storage, LLC, a subsidiary of NextEra Energy Resources, which appears to have been very quiet on the project.

An SEC filing from the Fortune 500 company, referring to the project as the Sunlight Storage Facility, said it is a 230MW/920MWh system. A four-hour duration is a requirement for projects in California to provide energy to utilities through Resource Adequacy, the framework by which grid operator CAISO ensures supply can meet demand, and the main revenue stream for BESS projects.
