In order to ramp up its peak capacity, Arizona Public Service Co. (APS) recently announced a request for proposals (RFP) to all technology sources.
APS is seeking 400 to 600 megawatts (MW) in additional capacity, and expects to issue the RFP on March 15 to both supply side and nonsupply side sources.
Each proposed facility must be at least 25 MW in size and located on a single site. Facilities must be able to link directly to the APS system or prove secured firm delivery transmission from the facility to the APS system.
Proposals should verify that vendors can commence delivery between January and June of 2020; each facility must be constructed and connected by June 1, 2020.
With the release of the RFP, APS will also issue proposed contract forms for each type of qualifying transaction. The RFP process will be overseen and reviewed by a third-party independent monitor.
APS plans to assess proposals based partly on the relative ability of each planned facility to effectively serve APS load. A bidder will not be obliged to enter the interconnection queue process unless and until its proposal is selected for final evaluation, to be decided by Sept. 15.
Registered bidders will be able to obtain more information before the release of the RFP through a communication such as stakeholder meetings, webinars and information posted online.
