HF 2580 sets specific setback requirements for renewable energy facilities (wind, solar, and battery storage) in Iowa, effective January 1, 2026. It prohibits local governments from imposing setback distances greater than defined limits: wind facilities must be 2x their height from homes/community buildings, solar facilities must be at least 50-100 feet from property lines or homes, and battery storage must be 50-100 feet from structures. The bill also restricts local authorities from enforcing stricter noise (max 47 decibels) or shadow flicker rules than specified. This directly affects developers of renewable projects, local zoning decisions, and property owners near proposed facilities.
This bill requires the state of Iowa to only rent or lease passenger vehicles with diesel engines that manufacturers explicitly confirm can run on biodiesel fuel blended at 20% or higher (B-20). It directly affects state agencies (specifically the Department of Administrative Services) and private companies bidding on state vehicle rental contracts. The requirement applies to all new or renewed contracts issued on or after July 1, 2026, extending an existing standard currently used for state vehicle purchases.
This bill exempts ethanol-blended gasoline containing over 85% ethanol from Iowa's excise tax when purchased exclusively for use in farm machinery (like tractors) used in agricultural production. It requires farmers to provide a completed exemption certificate to fuel suppliers at the time of purchase, which suppliers must keep for three years. If the fuel is later used for non-farm purposes, the farmer must pay the excise tax directly to the state. The change shifts from a post-purchase refund system to an upfront exemption, applying specifically to agricultural equipment fuel.
HF 2342 sets specific future dates for repealing various Iowa tax credit programs. The bill specifies that existing tax credits (like those for renewable chemicals, sustainable aviation fuel, and job creation) will end between 2028 and 2041, with most repeals occurring by 2032. It directly affects taxpayers and businesses currently claiming or planning to claim these credits, as they will no longer be available after the designated dates. The bill includes a key exception preserving credits issued or earned before January 1, 2032, ensuring existing agreements and carryforwards remain valid.
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.
HF 2549 requires Iowa's Department of Administrative Services to contract with certified technicians to conduct mechanical insulation energy audits for all state-owned buildings by January 1, 2028, and every four years after. The audits must identify missing or damaged insulation, check compliance with ASHRAE energy efficiency standards, estimate emissions and energy loss from poor insulation, and provide cost estimates for repairs. These audits directly affect state-owned buildings across Iowa by mandating a systematic review of insulation efficiency. The law aims to quantify energy waste and remediation costs to inform future energy-saving investments in state facilities.
HF 2313 prohibits coal-fired power plants and coal ash landfills from discharging toxic pollutants - including mercury, arsenic, and cadmium - from specific wastewater streams (like flue gas desulfurization water and ash transport water) into water sources. It directly affects existing coal power facilities operating before July 1, 2026, requiring them to comply by December 31, 2029, while new facilities must comply before starting operations. The bill mandates that the environmental department create implementing rules and aims to protect drinking water, groundwater, and communities from avoidable coal ash pollution linked to serious health risks. The law focuses on preventing toxic discharges using existing technology, with clear compliance deadlines for different facility types.
HF 2284 requires all Iowa wind turbines over 100 kilowatts to undergo annual safety inspections by qualified inspectors, covering structural, mechanical, electrical, and safety systems. Operators must submit detailed inspection reports to the Iowa Utilities Commission within 30 days and halt operations for safety issues until fixed within 90 days. The bill imposes civil penalties of up to $5,000 per turbine for missed inspections, $2,000 for late reports, and $10,000 for unresolved safety concerns. It directly affects wind energy operators statewide, with enforcement handled by the Iowa Utilities Commission, which will maintain a public inspection database and conduct random audits.
This bill makes tax exemptions for nuclear power facilities, web search portals, and data centers contingent on funding nuclear engineering programs at Iowa's public universities. Specifically, businesses receiving these exemptions must contribute at least 5% of their annual tax exemption value to state universities with nuclear engineering programs. If they fail to contribute, they lose their tax exemption eligibility and must repay all previously claimed exemptions. The bill directly affects new or expanded facilities in these sectors (with construction dates starting in 2027 for data centers and web portals) and requires annual contributions tied to their tax savings.
This bill increases Iowa's tax refund for biodiesel producers from 4 cents to 5 cents per gallon of biodiesel produced. It directly affects biodiesel manufacturers in Iowa by raising their quarterly refund amount based on total annual production. The refund calculation method remains unchanged - multiplying gallons produced by the rate - but extends the program's expiration from January 1, 2028, to January 1, 2031. The bill modifies existing tax provisions without altering eligibility or production requirements.
