EnergySolutions Advances Bid to Build New Nuclear at Kewaunee Site

The filing starts a yearslong federal process shaped by prospective tax credits alongside ongoing site work.

Overview

  • EnergySolutions filed a notice of intent and related permit submissions with the NRC for a major licensing action at the former Kewaunee plant, with the filings under review.
  • The company told regulators it plans to submit a full application by June 2028 and says it is conducting in-depth studies to demonstrate site suitability for new construction.
  • EnergySolutions is working with WEC Energy Group and is acquiring adjacent land, with state officials saying the build would occur on unused ground rather than by reviving the old unit.
  • The Wisconsin Assembly approved nuclear tax incentives on an 86–11 vote, and the measure now awaits Senate consideration before it could reach the governor.
  • Officials and experts expect a 10–15 year timeline for a new plant, the site retains transmission infrastructure, and debate continues over reliability benefits versus higher projected costs compared with wind, solar, and gas.
