WI SB502

Creates a nonrefundable nuclear energy generation tax credit beginning in tax year 2030, calculated as facility capacity in megawatts multiplied by $10,000 for the first 10 years, then decreasing by $1,000 annually until reaching $1,000 in year 19, with a maximum 19-year claim period per facility

Establishes nuclear energy as a high-priority state energy option, second only to energy efficiency and conservation, and adds nuclear to the state goal that all new electric generation capacity be based on renewable or nuclear resources

Authorizes the Public Service Commission to approve special electric tariffs for "very large customers" (facilities with at least 75 megawatts monthly demand) if the electricity comes from nuclear power and other ratepayers do not bear the costs; approval is mandatory if generation occurs within 75 miles of the customer

Permits electric utilities to recover pre-certification costs for nuclear energy development through rates, including feasibility studies, site evaluations, and regulatory filing preparation, plus a reasonable rate of return

Modifies the state's 10% renewable energy consumption goal to instead measure "low-carbon-emission energy" (renewable or nuclear), with a new reporting deadline of June 1, 2027
