The Salt River Project owns a 42% share of the soon to be retired 2,250 MW Navajo Generating Station. The projects listed in this article are a solid down payment on the more than 2.5GW of solar/wind and storage projects that will be needed to fully replace SRPs Navajo coal generation with renewables.
- Arizona's Salt River Project (SRP) on Thursday announced plans for two solar+storage projects that will push the utility more than 60% toward its goal of adding 1 GW of new utility-scale renewables by the end of fiscal year 2025. The Sonoran Energy Center will be the largest solar-charged battery project in the state, utility officials said.
- Sonoran will include a 250 MW solar array charging a four-hour battery system capable of storing 1 GWh. The second project, the Storey Energy Center, will be an approximately 88-MW solar and energy storage system.
An additional 20GW of coal will be retiring across the Western US over the next decade. The replacement of lost coal generation from Navajo with renewables will serve as a good example for other utilities across the West as they close their own coal plants.
