September 13 (Renewables Now) - Regional electric utility Arizona Public Service Company (APS) on Thursday officially launched two separate Requests for Proposals (RfPs) targeting up to 150 MW of solar and 250 MW of wind power.
Through the solar-dedicated RfP, the utility is looking for APS-owned solar resources that have the flexibility to add energy storage in the future. These projects should be completed by December 31, 2021.
The wind RfP, in turn, does not make it mandatory for the assets to be APS-owned and includes the option for third-party-owned resources that sell electricity under a power purchase agreement (PPA). These projects should be up and running as soon as possible, but no later than 2022.
Phoenix-based APS, which is the principal subsidiary of Pinnacle West Capital Corp (NYSE:PNW), said that the RfPs will help it expand its renewable energy portfolio to about 2,500 MW by 2021.
