Catclaw Solar + Storage Project
Catclaw Solar + Storage Project (project) is a planned solar photovoltaic power generating and energy storage system facility in Buckeye, Maricopa County, Arizona. The project will involve an up to 250-megawatt (MW) photovoltaic solar facility, 250-MW battery energy storage system, project step-up substation, and a 230-kilovolt (kV) generation-intertie (gen-tie) transmission line. The gen-tie will connect the project to the regional electrical grid via the existing Arizona Public Service (APS) Sun Valley Substation.

Permitting
Catclaw Solar received a Certificate of Environmental Compatibility (CEC) to allow for the construction and operation of the proposed 230 kV gen-tie transmission line. The CEC application was reviewed by the Arizona Power Plant and Transmission Line Siting Committee and approved by the Arizona Corporation Commission. Further information about the CEC process is available on the “Certificate of Environmental Compatibility” tab, above.
Catclaw Solar received a Community Master Plan (CMP) and Zoning Amendment approval from the City of Buckeye, Arizona. The CMP and Zoning Amendment allows for development of the project as an interim use of land previously slated for residential development by the city.
DESRI and its affiliates develop, acquire, own, and operate long-term contracted renewable energy assets in the U.S. DESRI’s portfolio of contracted, operating, and in-construction renewable energy projects currently includes 70 solar and wind projects representing more than nine gigawatts of aggregate capacity. An affiliate of DESRI purchased the Catclaw project in 2024.
