AB 174: Relating to: transmission facilities; installation of large wind energy, large solar energy, and battery energy storage systems; installation of light-mitigating technology systems; and prioritizing nuclear energy resources. (FE)

AB 174 amends energy statutes to redefine "renewable resources" for reporting purposes, explicitly including nuclear energy starting in 2026. It establishes new definitions for large-scale wind/solar systems (100+ megawatts) and battery storage, while clarifying that local governments cannot restrict energy installations more strictly than state rules. The bill affects energy developers, utilities, and local governments by changing how transmission contracts are audited and how renewable/nuclear projects are categorized. It does not create new project requirements but updates existing reporting frameworks for the state legislature and governor. The bill is pending in the Energy and Utilities Committee after being introduced in April 2025.

SJR 7: Relating to: recognizing that the Wisconsin State Legislature supports nuclear power and fusion energy as clean energy sources that are critical to safely meeting Wisconsin’s growing energy demands and declaring the legislature’s commitment to the continuation and expansion of nuclear power and nuclear technologies, the development of nuclear technologies and fusion energy, and employing the leadership and resources necessary to support the development of and investment in nuclear power, fusion energy, and related technologies in the state.

SJR 7 is a non-binding legislative resolution passed by Wisconsin's legislature declaring support for nuclear power and fusion energy as critical clean energy sources. It states the legislature's commitment to advancing these technologies, citing their role in providing 66.6% of Wisconsin's carbon-free electricity, powering 1.2 million homes, and supporting 650 high-paying jobs. The resolution does not create new laws or allocate funds but formally recognizes nuclear/fusion energy as essential for meeting energy demands and reducing emissions. It emphasizes Wisconsin's existing nuclear infrastructure (including two operating reactors) and academic resources as foundations for future growth in this sector.

SB 502: Relating to: a nuclear energy generation tax credit; prioritizing nuclear energy resources; approval of certain electric tariffs for very large customers; and authorizing electric utilities to recover certain precertification costs through rates. (FE)

SB 502 creates a 20-year tax credit for nuclear energy facilities in Wisconsin, providing electric utilities and cooperatives with annual credits of $10,000 per megawatt (decreasing to $1,000 by year 19) for qualifying nuclear power generation. The credit applies only to facilities located in Wisconsin that generated electricity during the tax year, with a cap of 20 years per facility. It also modifies definitions to include nuclear energy in "renewable resource" reporting for state agencies and utilities. The bill allows credit transfers to other taxpayers subject to state income tax, but prohibits partnerships and similar entities from claiming the credit directly.

SB 637: Relating to: a sales and use tax exemption and an income and franchise tax credit for nuclear energy facilities. (FE)

SB 637 creates two tax credits for nuclear energy facilities in Wisconsin: an income/franchise tax credit (under §71.07) and a sales/use tax exemption (under §71.28). It directly affects electric public utilities, cooperatives, municipal electric companies, and qualified wholesale providers that operate nuclear facilities. The credits cover wages paid to full-time facility workers (requiring 2,080 annual hours at ≥150% federal minimum wage) and capital expenditures for facility construction, operation, or maintenance (excluding land purchases). The credits are transferable to other taxable entities and apply to taxable years beginning after December 31, 2027.

AB 132: Relating to: creating a board to organize, promote, and host a Wisconsin nuclear power summit. (FE)

AB 132 creates a "nuclear power summit board" to organize, promote, and host a Wisconsin nuclear power summit in Madison, requiring the event to occur within one month after a specific university academic term begins. The board includes appointed legislators (two senators, two assembly members), the Wisconsin Economic Development Corporation CEO, a governor-appointed member, and nonvoting industry/faculty representatives. It is funded through a dedicated appropriation from the Wisconsin Economic Development Corporation, with the summit allowing free attendance for Wisconsin residents and varying registration fees for others. The board must disband 180 days after the summit concludes, returning remaining assets to the University of Wisconsin-Madison's nuclear engineering program.

AB 108: Relating to: a nuclear power siting study and time limits for taking final action on certain certificate of public convenience and necessity applications. (FE)

AB 108 requires the Public Service Commission to conduct a study identifying potential sites for nuclear power and fusion energy facilities, including advanced reactors, by a specific deadline. It also mandates that the Commission must make a final decision on applications for large nuclear facilities within 150 days of the application being deemed complete, or automatically approve the project. This directly affects applicants seeking permits for advanced nuclear power plants and the Commission's approval process. The bill aims to streamline approvals for new nuclear energy projects while establishing a formal study to identify suitable locations.

AB 472: Relating to: a nuclear energy generation tax credit; prioritizing nuclear energy resources; approval of certain electric tariffs for very large customers; and authorizing electric utilities to recover certain precertification costs through rates. (FE)

AB 472 creates a tax credit for nuclear energy generation in Wisconsin, directly affecting electric utilities operating nuclear facilities. The bill establishes a credit of $10,000 per megawatt for the first 10 years (decreasing annually to $1,000 by year 19), payable against state taxes for facilities operating in-state and generating electricity. Utilities may transfer or sell these credits to other taxpayers subject to state taxes. The legislation also reclassifies nuclear energy as a "renewable resource" for reporting purposes starting in 2026 and allows utilities to recover certain pre-certification costs through customer rates.
