Energy

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.
