Energy (Energy Storage)

HB 123 modifies how Iowa utilities set prices for new or significantly upgraded electricity generation, storage, and transmission facilities. It establishes new rules for approving large projects (340+ MW or major retrofits like carbon capture) and requires commission approval based on public interest, economic development, and avoiding facility duplication. The bill also creates land restoration standards for utility projects with landowner "right of first refusal," sets new regulations for anaerobic digester systems, and adjusts a revolving loan program for energy infrastructure. It does not change utility rates directly but affects how costs for qualifying projects are included in future rate calculations.

This bill sets uniform minimum distances for siting renewable energy facilities (wind, solar, and battery storage) across Iowa. Local governments must follow these specific setback rules - such as wind turbines needing to be twice their height from homes or 1.1 times their height from nonparticipating property - rather than creating stricter local rules. It directly affects developers building renewable projects and local authorities reviewing their applications. The bill standardizes requirements for safety, noise, and infrastructure, ensuring consistent implementation statewide without overruling federal aviation or safety codes.

SF 585 modifies how Iowa utilities calculate rates for large-scale energy projects. It establishes new ratemaking rules for electric power generation, energy storage, and transmission facilities over 340 megawatts, including projects that convert coal plants to gas, add carbon capture, or repower existing facilities. The bill explicitly encourages development of nuclear power and innovation programs, creating new tariffs for utility-led projects and setting land restoration standards. It also updates loan programs for energy infrastructure and adds regulations for anaerobic digester systems, affecting utilities planning major facility investments in Iowa.

HF 834 aims to update regulations for electric power generation, energy storage, and transmission facilities in Iowa, primarily affecting public utilities and energy consumers. It modifies the principles used by the commission to set rates for these facilities, allowing for advance specification of ratemaking for new construction or significant alterations, such as converting fuel sources, adding carbon capture, or repowering existing plants. The bill intends to encourage diverse energy technologies, including nuclear reactors and energy storage, to ensure reliable service and economic benefits. Additionally, it addresses land restoration standards, creates tariffs for public utility innovation programs, and establishes regulations for anaerobic digester systems.
