SB 1061: Relating to: moratorium on data centers.

SB 1061 imposes a moratorium on new data center operations in the state until specific requirements are met. It directly affects data center operators and developers by requiring: a statewide planning authority, prohibitions on shifting energy/water costs to residential customers, mandatory public reporting of water/electricity usage, and 100% renewable energy sourcing from newly built, directly accessible projects. The bill also mandates prevailing wages for construction workers, local referendum approval for new sites, and environmental safeguards for air, water, and noise. These provisions must be enacted by law before any new data center can operate.

SB 958: Relating to: creating the water fund for our future, granting rule-making authority, and making an appropriation. (FE)

SB 958 creates a dedicated "Water Fund for Our Future" with $250 million transferred from the general fund for state water infrastructure and emergency response. It establishes a rapid response account within the fund to cover costs for natural disasters and public health emergencies, including remediation, relocation, and assistance for affected individuals. A joint legislative committee oversees fund spending, ensuring money is only used for clean water activities and requiring written recommendations for funding requests. The fund also includes provisions for transferring unspent balances to the budget stabilization fund during fiscal shortages.

SB 1005: Relating to: state parks vehicle admission receipts purchased with motor vehicle registration.

SB 1005 allows vehicle owners to purchase an annual state park pass when registering or renewing their vehicle, with fees collected added to the conservation fund. It establishes three fee tiers: standard rates, discounted rates for households with existing passes, and reduced rates for senior citizens. Vehicle registration forms will include a section for selecting the park pass option, and the Department of Transportation will share purchaser lists weekly with the Department of Natural Resources. The bill directly affects all vehicle owners in the state during registration or renewal, with fees supporting state parks, recreation areas, and forest lands. Funds collected under this bill will be deposited quarterly into the conservation fund per statute.
failed · Wisconsin · Assembly Mar 23, 2026

AB 1051: Relating to: creating a deicer applicators registration program.

AB 1051 creates a voluntary registration program for commercial deicer applicators who remove snow/ice on privately owned properties for hire (e.g., contractors hired by homeowners or businesses). To register, applicators must complete department-approved training on water-quality protective methods, pass an exam, and maintain records of deicer use, weather conditions, and treatment dates for three years. Registered applicators gain limited liability protection if they follow approved methods and provide proof of registration in legal disputes, though this protection doesn’t apply for reckless conduct or failure to use approved methods. The program requires annual reporting to the department on deicer types and amounts used, with registration valid for five years and subject to revocation for noncompliance.

SB 1065: Relating to: requiring carbon monoxide detectors in child care centers and schools, grants for placing carbon monoxide detectors in schools, and making an appropriation. (FE)

SB 1065 requires all public and private elementary and secondary schools, as well as licensed child care centers, to install carbon monoxide detectors in rooms with fuel-burning appliances. Detectors must be battery-powered for older buildings or hardwired with fire alarm monitoring for newer buildings, and must meet safety certification standards. The bill also creates a $75,000 grant program to help schools purchase detectors, with grants up to $3,000 per school, and mandates annual reporting on grant usage. These requirements apply directly to schools and child care centers serving students or children, with the grants specifically targeting compliance costs.

AB 732: Relating to: prohibiting noncommercial uses of neonicotinoid pesticides. (FE)

AB 732 prohibits the use of neonicotinoid pesticides on outdoor ornamental plants, trees, or turf grown for noncommercial purposes (like home gardens or personal landscaping) starting January 1, 2026. The bill allows exceptions for tree injections, applications by certified professionals, and uses related to growing agricultural crops for sale. This directly affects homeowners and non-commercial landscapers who currently use these pesticides on decorative plants or lawns.

SB 863: Relating to: an energy efficiency grant program for school districts, granting rule-making authority, and making an appropriation. (FE)

SB 863 creates a new $10 million annual grant program for Wisconsin school districts to fund energy efficiency projects in school buildings, starting in the 2025-2026 school year. The bill specifically directs the Department of Public Instruction to award these grants, with priority given to projects upgrading heating, ventilation, and air conditioning (HVAC) systems. School districts seeking to reduce energy costs and improve building efficiency directly benefit from this funding. The program includes authority for the department to develop implementing rules and is funded at $10 million for both the 2025-26 and 2026-27 school years.
failed · Wisconsin · Senate Mar 23, 2026

SB 870: Relating to: Focus on Energy inclusion of programs promoting energy efficiency and renewable energy measures for low-income households and granting rule-making authority. (FE)

SB 870 requires Wisconsin energy utilities to spend at least 25% of their annual energy efficiency funds on programs for low-income households, including energy efficiency upgrades and renewable energy measures. The bill defines "low-income household" per state statute and mandates that these programs become a priority when setting energy efficiency goals. It also establishes minimum requirements for these programs and ensures utilities allocate funds annually toward reducing energy burdens for qualifying households. The law directly affects low-income residents and energy utilities across Wisconsin.

AB 869: Relating to: increasing the Focus on Energy rate and including residential energy storage in Focus on Energy. (FE)

AB 869 increases the required funding for Wisconsin's Focus on Energy program from 1.2% to 2.4% of energy utilities' annual retail sales revenue. It specifically adds residential energy storage systems (like home battery systems) to the list of eligible programs under the "energy efficiency program" definition. This means utilities must now dedicate more funding toward programs that help residential customers adopt energy storage, alongside traditional efficiency measures. The bill directly affects energy utilities (requiring higher spending) and residential customers (expanding access to storage incentives).
failed · Wisconsin · Assembly Mar 23, 2026

AB 876: Relating to: an energy efficiency grant program for school districts, granting rule-making authority, and making an appropriation. (FE)

AB 876 creates a new $10 million annual grant program for Wisconsin school districts to fund energy efficiency projects in school buildings, starting in the 2025-2026 school year. The program prioritizes projects focused on heating, ventilation, and air conditioning (HVAC) systems for schools. The Department of Public Instruction will administer the grants and may develop rules to implement the program. This directly affects public school districts seeking funding for building upgrades to reduce energy costs.
