IS 7390 and CUP 3595 (Horizon Tower, LLC)

The Athos Renewable Energy Project, specifically under award notice DBA-25-002 and Substantial Conformance No. 2 (CUP180001S02), involves the finalization of locations for three battery energy storage systems (BESS) in Riverside County, California. This project is supported by grant funding from the California Energy Commission's Distributed Energy Backup Assets (DEBA) Program to facilitate the purchase, installation, and performance reporting of a 75 MW portion of a larger 402.3 MW lithium-ion battery system. The scope is limited to these specific installations and additional mitigation measures, with no other alterations proposed to the original project entitlements. The project is governed by Conditional Use Permit No. 180001 and must adhere to the California Environmental Quality Act (CEQA). Environmental compliance is based on the County of Riverside's 2019 Final Environmental Impact Report and subsequent updates, ensuring that the 75 MW installation creates no new significant environmental impacts. Project oversight is managed by the California Energy Commission as the responsible agency and the Riverside County Planning Department as the lead agency, with strict adherence required for the 2019 and 2025 Mitigation Monitoring and Reporting Programs.
