Energy (Renewable Energy)

This Iowa bill (HSB 692) establishes specific siting rules for renewable energy facilities like wind turbines, solar arrays, and battery storage systems. It prohibits local governments from using eminent domain to acquire land for these projects and sets strict minimum distances: wind facilities must be at least three times their height from homes or community buildings, while solar and battery systems have fixed distance requirements (e.g., 50 feet from utility lines, 100 feet from homes). The bill limits local authorities to only certain standards, such as noise limits (max 47 decibels) and shadow flicker restrictions (max 30 hours/year), while requiring developers to repair infrastructure damage. It directly affects renewable energy developers, local zoning boards, and residents near proposed facilities.

This bill changes how excess energy credits are handled for customers with rooftop solar or other small-scale renewable energy systems (distributed generation). Under the new rule, unused credits must stay in a customer's account to offset future electricity bills until the customer specifically requests a cash-out or discontinues service. Previously, credits were automatically cashed out annually at the utility's avoided cost rate, splitting the funds between the customer and a low-income energy program. Customers now choose a January or April cash-out date when connecting their system, but credits remain available for future use without automatic payout.
