This bill extends Iowa's existing tax credit for E-15 gasoline, allowing retail gas dealers to continue claiming the credit against individual and corporate income taxes through 2028 (previously set to expire in 2026). It specifically allows dealers to claim the E-15 promotion tax credit for the full tax year, even if their tax year doesn't align with calendar years. The extension also preserves eligibility for the E-85 promotion tax credit when a dealer claims the E-15 credit in the same year. This change directly affects retail gasoline dealers who sell E-15 fuel, providing continued tax relief for their business operations.
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 404 establishes a community solar program in Iowa, enabling residents and businesses (subscribers) to join shared solar facilities and receive bill credits for the electricity generated. The bill sets specific rules: facilities must have at least three subscribers, limit size to 5 megawatts (or 20 megawatts on brownfield sites), and ensure at least 60% of capacity serves small users (≤40 kilowatts each). Electric utilities must provide bill credits for 25 years, apply unused credits to future bills, and create systems for tracking subscriber participation and renewable energy credits.
HF 780 prohibits the Iowa Utilities Commission from renewing permits for pipelines transporting liquefied carbon dioxide and limits all such pipelines to a maximum 25-year operational period. The bill amends existing law to specifically prevent permit renewals for CO2 pipelines, while maintaining the current 25-year maximum permit duration. This directly affects pipeline companies seeking to operate or extend operations for liquefied CO2 transportation. The measure focuses on setting clear, time-bound operational limits for these specific pipelines.
HF 302 amends Iowa law to remove language requiring consideration of reducing petroleum dependency or atmospheric contamination from agricultural energy policies. It specifically prohibits the Iowa Utilities Commission from factoring climate change into decisions about granting hazardous liquid pipeline permits. The bill changes two statutory sections: one eliminates references to reducing fossil fuel combustion impacts in agricultural energy support, and the other explicitly bans climate change as a consideration for pipeline permits. This directly affects the commission's permitting process for pipeline projects and the state's statutory framework for energy policy.
HSB 322 establishes a regulatory framework for community anaerobic digester systems that convert organic waste (like farm manure and crop residues) into renewable fuel and nutrient-rich digestate for fertilizer. It directly affects farmers, agricultural operations, and community projects using these systems by defining key terms, requiring permits, and setting fees for processing organic materials. The bill includes specific provisions for storing digester feedstock, manure, and digestate, along with penalties for non-compliance with safety and environmental standards. It creates a new legal chapter (the "Community Anaerobic Digester System Act") to govern these systems statewide. The bill focuses on standardizing operations to support renewable energy production from agricultural waste while managing environmental impacts.
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.
HF 860 prohibits state and local governments from enacting regulations on fuel-powered equipment. Specifically, it prevents these governmental bodies from creating rules based solely on the equipment's fuel source. This means state and local authorities can no longer implement policies that differentiate or restrict machinery because of the type of fuel it consumes.
HSB 237 extends several existing tax credits and sales tax refunds related to renewable fuels. It prolongs the availability of tax credits for retail dealers who sell E-85 gasoline, E-15 plus gasoline, and biodiesel blended fuel. Additionally, the bill extends sales tax refunds for companies that produce biodiesel. These provisions, previously set to expire between 2026 and 2028, are generally extended until December 31, 2030, or January 1, 2030. The bill also ensures these tax credits are available for an entire tax year for retail dealers whose tax year does not align with the repeal date.
HF 879 strengthens penalties for intentionally damaging critical infrastructure, such as power grids, water systems, or transportation networks. It increases criminal penalties for sabotage acts that threaten public safety or disrupt essential services. The law directly affects individuals who commit such acts by imposing stricter fines and potential prison sentences. This bill, signed into law by the Governor on May 1, 2025, modifies existing statutes to apply enhanced penalties to these specific offenses.
