MN Dept of Commerce preparing Environmental Impact Statement for Xcel Energy’s Monticello Nuclear Plant

4/4/2022 1:00:00 PM

The Minnesota Department of Commerce is preparing an environmental impact statement (EIS) on Xcel Energy’s request to the Minnesota Public Utilities Commission (PUC) for changes in the nuclear waste storage capacity at its Monticello Nuclear Plant. 


Xcel Energy has proposed to extend the operating life of the Monticello nuclear plant to the year 2040. To accommodate the additional spent nuclear fuel associated with extending the lifetime of the plant, Xcel Energy has requested that the PUC authorize additional storage within the plant’s existing independent spent fuel storage installation. Xcel Energy estimates that approximately 14 additional spent fuel storage canisters will be needed to facilitate plant operations through 2040. 

The EIS being prepared by Commerce will be used by the PUC in making its decisions on Xcel Energy’s request for additional storage; it will evaluate the potential human and environmental impacts of Xcel Energy’s proposal. The EIS will be prepared in accordance with the scoping decision issued by Commerce earlier this month.  

A draft of the EIS is anticipated to be completed and available in October 2022.  Public meetings and a comment period on the draft EIS will follow.  Timely and substantive comments on the draft EIS will be responded to in a final EIS.  The final EIS is anticipated to be available in January 2023, for use by the PUC. 

The EIS scoping decision is available:
