What can Coconino County require of a project?
Arizona has no state siting permit for solar, wind, or battery plants and no state decommissioning law, so Coconino County's own zoning sets most of the rules; a transmission line of 115 kV or more needs a state certificate (state rules).
County rules and recent actions: The county zoning ordinance (last amended December 16, 2025, effective January 15, 2026) has a section on utility-scale renewable energy systems (Section 3.19) and one on accessory wind systems (Section 3.11). (Coconino County zoning ordinance)
