Red Rock Solar Plant
Located on 400 acres in a remote region of Arizona about 30 miles south of Casa Grande, this project represents the largest Arizona Public Service solar plant to date with 2,286 single-axis trackers supporting 182,880 photovoltaic panels, generating 40 megawatts (MWac) of solar energy.
There were 174 workers on the project during peak construction and no recordable safety or lost-time accidents. It was McCarthy’s sixth solar project working for APS, allowing the company to expand its solar portfolio and solar leadership in Arizona. This was APS’ largest grid-scale solar plan and is located next to the company’s first solar plant, built more than 20 years ago.
