Purpose

This bill aims to shape Minnesota’s energy rules around nuclear power by controlling when the state can approve new nuclear plants and by requiring careful consideration of spent fuel storage. It also references small modular reactors as part of the policy direction.

Main Provisions

• Certificate of Need (CON) restrictions for new nuclear plants:
  • The Minnesota Public Utilities Commission (the commission) may not issue a certificate of need for constructing a new nuclear-powered electric generating plant, except as provided in a specific exception.
• Exception for small-scale capacity:
  • The commission may issue a CON to construct a new nuclear-powered generating plant if the plant’s maximum generation capacity is up to 300 megawatts (MW).
• Spent nuclear fuel storage consideration:
  • For a CON regarding additional storage of spent nuclear fuel at a facility seeking a license extension, the application must address the impacts of continued operations over the period for which approval is sought.
• Overall scope:
  • The bill narrows when new nuclear plants can be approved and sets a clear upper size limit (300 MW) for plants that may qualify under the exception.

Significant Changes to Existing Law

• Adds a strong limitation on issuing new CONs for constructing nuclear-powered generating plants, effectively blocking most new builds unless the 300 MW exception applies.
• Introduces a requirement to evaluate the long-term impacts of continued operation for spent fuel storage tied to license extensions.
• Clarifies that a limited class of new nuclear projects (at or below 300 MW) may proceed under a CON, signaling a move toward smaller-scale nuclear options (e.g., small modular reactors) within the state’s regulatory framework.

Implications and Context

• Regulatory impact: This bill tightens state control over new nuclear development and places a focus on the scale (MW limit) and long-term fuel storage impacts in licensing decisions.
• Energy planning: Could influence Minnesota’s future mix of electricity generation by prioritizing smaller-scale nuclear options or delaying larger conventional nuclear projects.
• Oversight emphasis: Elevates the importance of long-term environmental and operational impact analyses for spent fuel storage when license extensions are considered.
