Purpose

• Establish a regulatory framework to create and expand thermal energy networks (TEN) as an alternative to traditional gas service.
• Require public utilities to develop TEN service plans, promote emissions reductions, support local jobs and training, and protect customers, including low-income households.
• Outline how TEN projects are planned, funded, approved, and ultimately how existing gas infrastructure may be decommissioned.

Main Provisions

• Definitions and scope
  • Introduces and clarifies terms such as public utility, thermal energy network (TEN), TEN service plan, project costs, and building costs.
  • Establishes that TENs are plans to build networks that deliver thermal energy to customers and that utilities must submit such plans for approval.
• TEN service plan requirements
  • A TEN service plan must describe the project area, the number and type of customers served, estimated project and building costs, construction schedule, and a plan to offset costs with incentives.
  • Must include anticipated benefits, efforts to promote local economic development and job creation, and measures to include progressive state labor policies (local prevailing wage standards, apprenticeships, or project labor agreements).
  • Requires a clearly identified transition plan if TEN would replace gas service for some customers, including timelines, customer assistance, incentives to connect to the TEN, communication plans, and information on projected heating/cooling costs for individual customers.
  • Must address protections for low-income customers and how to handle stranded gas infrastructure and avoided operating costs.
  • Public education and community engagement requirements, with meetings held at accessible times and locations.
• Service delivery and Commission oversight
  • A public utility may supply TEN service if the TEN service plan is approved by the Public Utilities Commission (PUC), which can approve, modify, or reject plans.
  • The plan must include a customer waiver process allowing exemptions from transitioning off gas if it is unduly financially burdensome or technologically infeasible.
  • The utility must inform customers about the project, timelines, benefits, and available incentives; include a transition schedule for affected customers; and consider emissions reductions.
  • The Commission must assess cost effectiveness, lifetime costs and benefits (including future emissions reductions), and determine decommissioning timelines for gas infrastructure.
  • The plan should include guidelines if a TEN service area includes customers of another utility.
• Consumer protections and protections under existing law
  • TEN service is subject to the same consumer protections and regulatory authority as gas service, including specific sections of Minnesota law.
• Cost recovery
  • Utilities may recover reasonable and prudent TEN-related costs through general rate cases, subject to PUC approval.
  • Costs for gas infrastructure in TEN-served areas are generally not recoverable unless necessary to ensure safety of decommissioned gas infrastructure.
• TEN priority zones and siting
  • The decision of where to locate TEN projects should prioritize areas where TEN is a more prudent resource than new gas infrastructure, or where there is little or no existing gas infrastructure, or where existing gas infrastructure is aging or prone to leaks.
  • Community interest in TEN, similarities to successful pilot projects, and other site characteristics are considered.
  • The commission and commissioner guidance reference existing laws related to site suitability studies and related prioritization criteria.

Significant Changes to Existing Law

• Expands regulatory framework from traditional gas/electric service to include thermal energy networks as a formal, plan-driven utility alternative.
• Requires explicit TEN service plans with detailed content, public participation, and transition planning.
• Creates a formal process for evaluating the cost-effectiveness and emissions impacts of TEN projects, including consideration of decommissioning timelines for gas infrastructure.
• Introduces dedicated provisions for workforce requirements (prevailing wage, apprenticeships, etc.) and local economic benefits in TEN projects.
• Establishes priority-zone criteria to guide siting and prioritization of TEN projects over new gas infrastructure.
• Clarifies cost-recovery rules, including limitations on recovering gas-infrastructure costs in TEN areas and allows recovery of TEN-specific costs through rate cases.
• Integrates TEN planning with broader state emissions reduction goals and ongoing energy policy.

Potential Impacts to Stakeholders

• Utilities: Must develop and seek approval for TEN service plans, manage timelines, and coordinate transitions for customers, while navigating cost-recovery rules.
• Customers: Potential access to cleaner or more efficient energy options, with new costs and incentives; protections for low-income customers; options to waive transition if burdensome.
• Employees and local communities: Expected emphasis on local hiring, prevailing wages, and apprenticeship opportunities tied to TEN projects.
• Gas infrastructure: Plans may decommission or repurpose gas lines, with cost and safety considerations addressed in the plan and by the Commission.
