Big Rock 2 Cluster Solar and Storage Project

The Big Rock 2 Cluster Solar and Energy Storage Project involves the construction and operation of a utility-scale photovoltaic solar energy generation and battery energy storage system facility. Located on approximately 1,849 acres of privately owned land across 24 parcels in the unincorporated area of Imperial County, California, the project is led by applicant 90FI 8ME LLC. The facility will feature up to 500 MW of solar energy generation equipment, including a substation and access roads, and up to 500 MW of battery energy storage. Additionally, a Gen-tie line reaching up to 200 feet in height will connect the on-site substation to the Imperial Irrigation District's existing Liebert Switchyard. The project received approval from the Imperial County Board of Supervisors on December 9, 2025, following the completion of an Environmental Impact Report in compliance with CEQA. This approval encompasses a General Plan amendment, a Zone Change, four Conditional Use Permits, and four Variance requests. The project is situated at 1520 Jessup Rd. in El Centro, California, and is managed through the Imperial County Planning and Development Services office.
