Z250031 — Battery energy storage system (BESS) facility with power generation and distribution uses; 800-MW storage system with approximately 15 acres reserved for power transfer substation use in Maricopa County, AZ
This rezoning request would convert 65 acres from Rural-190 to IND-2 IUPD to enable an 800-MW battery energy storage system facility, part of the larger Sun Basin regional energy project. The site is ideally positioned adjacent to existing power infrastructure and industrial uses near Palo Verde Nuclear Generating Station, with no known public opposition and no outstanding agency concerns. The applicant has requested modified development standards including reduced setbacks, no parking requirements, and chain-link fencing instead of masonry walls to accommodate the BESS facility design.
