AB 619 creates a $150 million grant program to fund aviation biofuel manufacturing projects in Wisconsin, funded through state public debt issuance. The bill requires grantees to use facilities exclusively for aviation biofuel production (with limited exceptions for other biofuels if 80% of output is aviation fuel), source 80% of biomass locally, and invest at least $1.5 billion in aviation biofuel manufacturing within five years. It directly affects companies building such facilities and the Department of Natural Resources, which administers the grants. The program aims to support the state's forest products industry and create jobs, with strict repayment terms if grantees fail to meet requirements.

AB 657 exempts sales and use taxes for specific equipment and materials used exclusively in qualified nuclear fusion technology projects. It covers over 70 listed items, including plasma heating systems, superconductors, diagnostic tools, specialized materials like lithium and tungsten, and safety equipment. The exemption applies to businesses conducting fusion projects focused on energy generation, medical isotope production, research, or other fusion-related applications as defined in the bill. This policy directly reduces costs for companies developing nuclear fusion technology by eliminating taxes on qualifying purchases.

AB 840 regulates data centers in the state by requiring specific operational and environmental standards. It mandates that data centers use closed-loop cooling systems (recycling water instead of using fresh water) and report annual water usage to the department. The bill also requires renewable energy facilities serving data centers to be located on-site and prohibits utility customers from paying for data center infrastructure costs. Additionally, operators must provide financial bonds for construction and restore land if projects are abandoned. These provisions directly affect all data center operators and developers in the state.

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.
