After announcing nearly a gigawatt of new clean-energy projects in February, APS is now seeking proposals to build two of them in different parts of the state. The first request for proposals (RFP) seeks partners to add batteries to existing APS solar plants in rural Arizona, storing their power for use after the panels stop producing each day. A second partner is being sought to develop a large (100-MW) solar plant paired with an equal amount of storage, to bring more clean energy to customers after dark. Both of these projects will provide APS customers with more solar after sunset, serving their evening energy needs with an even cleaner resource mix.
