AZ HB2527

Prohibits the Arizona Corporation Commission from approving retirement of electric generation facilities unless a replacement facility with equal or greater power generation capacity is already available on the grid, accounting for other states' planned closures.

Requires the Corporation Commission to prioritize dispatchable (on-demand) electricity sources over nondispatchable sources and project at least a 5 percent increase in dispatchable electricity between 2025 and 2030.

Directs electric generation facilities to notify the Commission within 30 days of receiving notice of external regulatory actions that would make continued operation economically infeasible, triggering an investigatory docket.

Authorizes the Commission and Attorney General to seek waivers, injunctions, or other legal action to prevent federal regulations from forcing closure of firm power plants until replacement capacity is available.

Defines key terms including "dispatchable" (readily available or adjustable on demand), "firm power" (reliable power or battery storage exceeding 24 hours), and "reliable" (80 percent or greater performance standard with non-intermittent availability).
