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.
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.
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.
House File 1053 modifies fuel taxation policies, primarily affecting retail dealers of E-15 gasoline and producers of biodiesel. The bill extends the E-15 gasoline tax credit, delaying its repeal from January 2026 to January 2029. However, for calendar year 2028, the E-15 credit will be reduced from nine cents to four and a half cents per gallon and will no longer be refundable. Additionally, the bill increases the sales tax refund available to biodiesel producers from four cents to four and a half cents per gallon produced.
This bill, known as the "Community Anaerobic Digester System Act," establishes a framework for processing organic materials, such as agricultural manure, into renewable fuel and digestate. It defines various components and types of anaerobic digester systems, differentiating between general systems and "community" systems not tied to specific animal feeding operations. These systems are designed to break down organic matter to produce biogas and a nutrient-rich byproduct. The act also includes provisions for associated fees and penalties.
HSB 312 allows Iowa state banks to purchase federal tax credits for clean energy projects without investment limits. Specifically, it permits state banks to invest freely in tax credits authorized under federal law (26 U.S.C. §45 and §48), which typically support renewable energy development. The bill directly affects Iowa state banks by expanding their investment options in these federal credits. This change removes previous restrictions on banks holding such credits for their own accounts.
