Arizona Public Service Co. announces a Request for Proposal (RFP) from solar developers and installers to construct two 10-megawatt solar photovoltaic facilities – financed by APS through the company’s AZ Sun Program.

The RFP began on June 16, and interested parties are encouraged to participate in a bidder’s webinar on June 23. Additional information about the webinar and the RFP is available online at aps.com/rfp.

Projects must utilize commercially proven technology. When completed in 2015, the new solar facilities – one located on Luke Air Force Base and the other to be built in partnership with the City of Phoenix – will be owned and operated by APS. These facilities will join seven other AZ Sun Projects that are already online or under construction, totaling 170 MW of solar energy for Arizona – enough to power more than 42,000 APS customers.

With the AZ Sun Program, APS is investing in the development of solar photovoltaic power plants across Arizona. The program allows APS to partner with third-party developers and equipment providers to design and construct the facilities, which increase the opportunity for more developers to participate since project financing is provided by APS.

APS, Arizona’s largest and longest-serving electricity utility, serves nearly 1.2 million customers in 11 of the state’s 15 counties. With headquarters in Phoenix, APS is the principal subsidiary of Pinnacle West Capital Corp. (NYSE: PNW).
