SF 2214 requires Iowa's Department of Transportation (DOT) to coordinate with utility companies upon written request when planning transmission line placements on highway corridors. It mandates the DOT to assign a project coordinator within 30 days and share future highway project plans that might affect transmission lines. The bill allows longitudinal transmission lines on primary roads (including interstates) with DOT approval, unless safety or highway function is threatened, and requires public disclosure of denial reasons within 90 days. This directly affects utility companies seeking to install lines along highways and the DOT's permitting process. The law updates existing rules to create a more structured, timely coordination process for transmission line installations.
HF 2372 requires Iowa's Department of Administrative Services to contract with qualified contractors to assess mechanical insulation (insulation around pipes, boilers, and HVAC systems) in all state-owned public buildings within 10 years. The assessment must identify energy-saving opportunities, health risks, and necessary repairs, with findings posted online within 30 days. If repairs could cut carbon emissions and energy use by over 30%, the department must implement them within 12 months; immediate action is required for health or safety issues. The law expires on July 1, 2037.
SF 2433 updates Iowa's electrical code framework by adopting the International Energy Conservation Code (IECC), 2009 edition, as the "national energy code." It requires the electrical board to analyze cost impacts on new homes before adopting energy code changes, and mandates sellers of single-family homes built after January 1, 2027, to disclose in writing if the home doesn't meet the 2024 IECC standards. This bill directly affects homebuilders, electrical code administrators, and home sellers/buyers. The key mechanisms are the pre-adoption cost analysis and the new disclosure requirement for home sales. The bill takes effect January 1, 2027.
This Iowa bill (HF 2682) requires public utilities and transmission companies operating electric lines in the state to study grid-enhancing technologies and reconductoring opportunities. Starting January 1, 2027, and every three years after, these entities must submit public reports to the Iowa Utilities Commission analyzing the feasibility of projects that could increase transmission capacity, reduce congestion, support renewable energy, improve reliability, or lower line losses. The studies must cover costs, implementation timelines, and how projects align with specific grid improvement goals like reducing siting conflicts or serving new customers. Municipal utilities, cooperatives, and single-customer transmission lines are exempt from this requirement.
This bill extends Iowa's biodiesel blended fuel tax credit for retail dealers until January 1, 2033, instead of the previous 2028 expiration. It directly affects businesses selling biodiesel-blended fuel who claim this credit on their income taxes. The key provision ensures these dealers can claim the full credit for their entire tax year - even if their tax year doesn't end on December 31 - by aligning the credit calculation with the new 2033 repeal date. This change provides continued financial support for biodiesel retailers without altering the credit's structure.
SF 2447 establishes statewide setback requirements for renewable energy facilities in Iowa, directly affecting local governments (cities/counties) and developers of wind, solar, and battery storage projects. The bill mandates specific minimum distances: wind facilities must be 3 times their height from homes/community buildings, 1.1 times their height from non-participating property, and 1.1 times their height from roads or utility lines. Local authorities cannot enforce stricter setback rules than these standards, though they may adopt limited additional requirements like a 30-hour annual shadow flicker limit or 47-decibel sound limits. The law applies to all wind facilities proposed after January 1, 2025, and sets uniform rules to streamline approvals for renewable projects.
HF 2076 changes how Iowa electric utilities handle unused energy credits for customers with distributed generation (like rooftop solar). It requires utilities to keep excess kilowatt-hour credits in a customer’s account to offset future bills, rather than automatically cashing them out annually. Customers must now actively request a cash-out or when ending service, at the utility’s avoided cost rate, with funds split between the customer and the low-income energy assistance program. This bill directly affects residential and small business solar customers who generate excess electricity.
This bill requires Iowa's Utilities Commission to adopt rules prohibiting gas and electricity disconnections from homes during severe cold or severe hot weather, as defined by those rules. It directly affects residential utility customers by preventing service cutoffs during extreme temperature events. The key provision mandates the Commission to establish specific definitions for "severe cold weather" and "severe hot weather" in its rules, building on existing protections for severe cold. The bill does not create new penalties or funding but modifies the Commission's rulemaking authority to cover both temperature extremes.
This bill authorizes the Iowa Economic Development Authority to transfer up to $633,000 annually from the energy and water infrastructure revolving loan fund to Iowa State University of Science and Technology. The funds must be used to provide financial assistance to the state load forecasting center, which supports electricity grid planning. The transfer is required to begin July 1, 2026, and applies to each subsequent fiscal year.
This bill defines "portable solar generation devices" as small, moveable solar units (max 1,200 watts) designed to connect to standard household outlets, offset personal electricity use, meet safety codes, and include outage safety features. It prohibits utilities from requiring customer approval for installation, charging fees, or demanding extra equipment beyond the device itself. The bill also exempts these devices from standard interconnection rules and net metering requirements. It directly affects homeowners installing small-scale solar systems under 1.2 kilowatts for personal use.
