It is owned and operated by Salt River Project, a major utility serving the Phoenix metropolitan area. The plant plays a key role in meeting regional electricity demand. The facility operates on natural gas, a fuel that offers lower emissions compared to coal but still contributes to CO2 and NOx emissions. As a gas plant, it likely uses combined-cycle or simple-cycle technology, though specific configuration is not detailed. The plant's capacity places it in the medium-to-large scale for gas power generation in the US. Kyrene operates under the regulatory framework of the US Clean Air Act, including NAAQS and regional haze rules. Its proximity to populated areas means emissions are subject to strict state and federal oversight. The plant supports grid reliability and integrates with renewable sources as part of Salt River Project's diverse generation portfolio.

The plant's gas fuel type results in lower CO2 emissions per MWh compared to coal, but still contributes to greenhouse gases and local air pollutants like NOx. Its location near Phoenix means emissions affect a large urban population, subjecting it to stringent air quality regulations under the Clean Air Act.
