Avantus has announced the sale of the Catclaw Solar and Energy Storage Project to D E Shaw Renewable Investments (DESRI).
Located in Buckeye, Maricopa County, Arizona, the scheme features up to 225MWac of solar and 250MW/1,00 MW-hours of energy storage.
The transaction includes a long-term PPA with Arizona Public Service (APS) for the project.
Avantus was responsible for the initial greenfield development including interconnection, site acquisition and permitting, as well as commercial negotiations with APS and the procurement of select equipment, including batteries.
Avantus executive vice president of development Jason Moretz said: “At Avantus, we are committed to pushing forward the transition to a sustainable economy by developing safe, reliable clean energy projects.
“Catclaw is a perfect example of this commitment and will provide economic and environmental benefits to Arizona and the local community, while helping Arizona manage increasing demand for power during heatwaves.
“Today’s announcement marks the first Arizona project in our portfolio to reach this milestone and furthers our long-standing relationship with DESRI.”
Catclaw marks the fourth scheme Avantus has sold to DESRI, which DESRI expects to bring online in 2026.
DESRI chief strategy officer Robert Schoenherr said: “DESRI is pleased to continue our partnership with Avantus, a top U.S. developer of utility-scale solar and solar-plus-storage projects.
“Projects like Catclaw underscore our commitment to supporting new clean energy investment across the nation. We are proud to add Catclaw to our current portfolio of Arizona projects, and to count APS as a new customer.”
