About the project
On Monday, May 16, SRP filed a request for rehearing by the Arizona Corporation Commission (ACC) to reconsider its decision to deny SRP a Certificate of Environmental Compatibility (CEC) to expand its peak-demand natural gas facility in Coolidge. Unless reconsidered and reversed, the ACC's vote will impair the reliability of the SRP system, creating serious risk of insufficient resources necessary to meet customer demand in 2024. It will also undermine SRP's ability to integrate additional renewable resources, as the utility will lack critical quick-start, flexible generation in times of peak demand.
On April 12, the ACC rejected the recommendation by its own Power Plant and Transmission Line Siting Committee to approve a CEC for SRP's Coolidge Expansion Project. This Committee is a selected group of experts that conducted a thorough assessment of SRP's application, including eight days of public hearings and testimony. In addition to the Committee's recommendation for the ACC to approve the proposed project application, the ACC's own utility staff confirmed SRP's application was complete, and recommended the ACC approve it.

Salt River Project Agricultural Improvement and Power District (SRP), a community-based, not-for-profit utility based in Tempe, Arizona, is applying for a Certificate of Environmental Compatibility (CEC) for the expansion of the Coolidge Generating Station.
The Coolidge Generating Station is a natural gas power plant near Coolidge, Arizona, that was built between 2009 and 2011. SRP purchased the plant in 2019 to help support growing demand for power in the region.
The proposed Coolidge Expansion Project (CEP) will allow SRP to meet the significant near-term increase in energy needs in its service territory, which is among the fastest growing regions in the nation. In addition, the CEP will enable the addition of more renewable resources while maintaining a reliable power grid.
A virtual open house is available and can be viewed on-demand, 24 hours a day.
As part of the CEC process, SRP is seeking public input for the Coolidge expansion, which would include construction of up to 820 megawatts (MW) of new power generation produced by 16 gas turbines.
