The combination of solar power and battery storage edged out natural gas, which is the go-to technology for peaking plants

Solar photovoltaic panels in the desert near Phoenix may seem unremarkable. After all, the southwestern United States offers some of the best solar conditions in North America.

But a recently announced 65 megawatt (MW) project is making news by coupling solar PV with battery energy storage, a first for utility Arizona Public Service, which solicited proposals in 2017 for generation sources to provide electricity during peak demand hours.

Perhaps more noteworthy is the fact that the solar-plus-storage bid beat out other generation sources, including multiple proposals for natural gas plants. (The utility has an agreement with an existing natural gas-fired plant for a total of 570 MW for the summers of 2020 through 2026.)
