Green energy setbacks; creating setback requirements for certain solar energy farms; modifying setback provisions for wind energy facilities; effective date.

HB 1451 establishes new setback requirements for utility-scale solar farms and modifies existing rules for wind energy facilities in Oklahoma. Solar farms must maintain at least 1.5 nautical miles from airports, schools, hospitals, and 3 nautical miles from nonparticipating property lines, while wind facilities face similar distance rules plus military airspace protections. Developers must attest to compliance in reports filed with the Oklahoma Corporation Commission, and disputes over setbacks fall under district court jurisdiction. Violations for wind projects affecting military airspace could trigger daily penalties up to $1,500, with enforcement handled through administrative courts. The bill takes effect November 1, 2025.
