corporation commission; non-thermal generating unit

This bill amended Arizona law to define "plant" as including non-thermal electric generating units (like solar or wind farms) with a capacity of 200 megawatts or more, alongside existing thermal units. It directly affects large-scale energy developers and the Corporation Commission, which regulates such facilities. The change clarifies which projects fall under the Commission's jurisdiction for siting and environmental review, without creating new requirements. The bill passed the legislature in April 2025 but was vetoed by the Governor on May 2, 2025, so it did not become law.
