APS Seeks Additional Peaking Capacity

Arizona Public Service Co. (APS) announces a request for proposal (RFP) for dispatchable capacity to meet peak demand. The RFP will be released on January 30 with a bid submittal deadline of March 18, 2015.

APS is seeking approximately 300 megawatts of peaking capacity, which may be bid as a power purchase agreement or a build, own and transfer structure. Proposals must demonstrate that projects can achieve commercial operation by the summer of 2018 or 2019. The entire RFP process will be monitored and reviewed by a third-party independent monitor.

Proposals will be evaluated and compared to an APS self-build option to expand the existing Ocotillo Power Plant site located in Tempe, Ariz.
