Summary

This bill establishes a framework to promote nuclear energy development in Wisconsin through several key provisions. It creates a nuclear energy generation tax credit and establishes special electricity tariffs for "very large customers" (those with peak demand of at least 100 megawatts) that must source at least 80% of their energy from nuclear facilities, with expedited approval if the nuclear plant is located within 75 miles of the customer. The bill also authorizes electric utilities to recover certain precertification capital costs through customer rates via interim orders from the Public Service Commission, including costs that exceed initial limits if due to regulatory compliance or unforeseen circumstances. These measures collectively aim to incentivize nuclear energy investment and make it financially viable for utilities to serve large industrial customers, particularly data centers and manufacturing facilities, with nuclear-generated electricity.
