Summary

Arizona Public Service (APS) plans to convert two units of the Cholla Power Plant in Navajo County from coal to natural gas. The plant, which first began operations in 1962, will come back online in 2029, generating about 380 megawatts of power — enough for roughly 60,000 homes. The coal units were fully phased out in March 2025 due to federal environmental regulations, and the conversion aims to meet Arizona's growing electricity demand.
