A bill for an act relating to the regulation of public utilities, including rate filings, rate adjustment mechanisms, virtual power plants, and integrated resource planning.

HF 2365 regulates Iowa's electric utilities by setting rules for rate filings, automatic rate adjustments, virtual power plants, and long-term planning. It requires rate-regulated utilities to file general rate cases every three years (starting July 2029), limits frequent rate changes to once per year without approval, and prohibits automatic rate adjustments for transmission costs. The bill defines "virtual power plants" as customer-owned energy resources managed centrally (not classified as utilities) and mandates commission approval based on customer benefits. It also requires utilities to submit detailed 3-year integrated resource plans by July 2027, including 5- and 20-year forecasts for energy needs, costs, and resource options like efficiency programs and distributed generation. These plans must be evaluated using standardized data and include public input processes.
