Safety rules for big wind turbines near homes

Beginning January 1, 2026, new wind turbines 500 feet tall or more that are built under a state wind energy agreement cannot be placed within 1,500 feet of an occupied home, unless the property owner agrees to a shorter distance. Height is measured from ground level at the base to the tip of the blade. For turbines 500 feet or taller that sit within 1,500 feet of a home and are in areas with an ice class of 4 or higher, operators must use commercially reasonable steps to reduce icing risks during operator‑controlled blade deicing. During deicing, rotor speed is capped at 10% of the turbine’s maximum speed, unless the property owner approves a different speed.
