APS’s Battery Addition Extravaganza


Date: Apr 04, 2019

Hundreds of megawatts of battery storage are coming to the desert via a request for proposals as part of APS’ initiative to add around 1 GW of clean-energy projects by mid 2025.

What goes great with a gigawatt of renewable energy? That’s easy, battery storage for backup and flexibility. That’s also exactly what’s happening in Arizona, as Arizona Public Service (APS) announced today a request for proposals (RFP) to bring hundreds of MW in capacity of energy storage to both new and existing solar facilities.

Like aging starlets, APS’s Chino Valley (19 MW) and Red Rock (40 MW) solar projects will be getting a face lift, though instead of silicon, they will come from, presumably, lithium-ion batteries. While APS has not yet released the exact capacity of the batteries to be partnered with these projects, the battery capacities that have been revealed at other projects all match the nameplate capacities of the projects they’re coupled to, so it would be a bit surprising if that were not the case with these two. APS anticipates both of these projects to be completed by 2021. The two projects are also the final step of APS’ February announcement that the company would be developing 200 MW of battery storage to be paired with existing solar facilities.
