The bill establishes nuclear energy as a high-priority option for state energy policy, introduces a nuclear energy generation tax credit, and modifies energy project design priorities.

  • 1.12 (3) (b)

    It is the goal of the state that, to the extent that it is cost-effective and technically feasible, all new installed capacity for electric generation in the state be based on renewable energy resources, including hydroelectric, wood, wind, solar, refuse, agricultural and biomass energy resources. → It is the goal of the state that, to the extent that it is cost-effective and technically feasible, all new installed capacity for electric generation in the state be based on renewable energy resources, including hydroelectric, wood, wind, solar, refuse, agricultural and biomass energy resources, or nuclear energy.

    The goal of energy generation now includes nuclear energy alongside renewable resources.

  • 1.12 (5) (a)

    renewable energy resources → renewable or nuclear energy resources

    Nuclear energy resources are now included in the prioritization for energy project designs.

  • 16.75 (12) (a) 4.

    “renewable resource” has the meaning given in s. 196.378 (1) (h) 1. or 2. and includes a resource, as defined in s. 196.378 (1) (j), that derives electricity from hydroelectric power. → Except as provided under par. (e), “renewable resource” has the meaning given in s. 196.378 (1) (h) 1. or 2. and includes a resource, as defined in s. 196.378 (1) (j), that derives electricity from hydroelectric power.

    The definition of renewable resource remains unchanged except for conditions under new provision (e).

  • 16.75 (12) (e)

    Beginning in 2026, and only for purposes of the report under this paragraph, “renewable resources” also includes nuclear energy resources.

    From 2026, nuclear energy will be considered alongside renewable resources in specific reporting contexts.

  • 66.0627 (1) (bk) 2.

    An improvement to a premises that allows for the small scale derivation of electricity from a renewable resource listed under s. 196.378 (1) (h). → An improvement to a premises that allows for the small scale derivation of electricity from a renewable low-carbon-emission resource described in s. 196.378 (1) (h).

    Clarifies that improvements can derive electricity from low-carbon-emission resources, including nuclear.

  • 71.05 (6) (a) 15.

    The amount of the credits computed under s. 71.07 (2dm), (2dx), (2dy), (3g), (3h), (3n), (3q), (3s), (3t), (3w), (3wm), (3y), (4k), (4n), (5f), (5h), (5i), (5j), (5k), (5r), (5rm), (6n), and (10), and (12) and not passed through by a partnership, limited liability company, or tax-option corporation that has added that amount to the partnership’s, company’s, or tax-option corporation’s income under s. 71.21 (4) or 71.34 (1k) (g).

    No specific change noted; references to credits are clarified.

  • 71.07 (12)

    NUCLEAR ENERGY GENERATION CREDIT . (a) Definitions. In this subsection: 1. “Applicable credit factor” means one of the following: a. For each of the first 10 tax years for which a claimant claims a credit under this subsection ...
