MN HF4122

Expands the definition of "public utility" and "service" in Minnesota law to include thermal energy networks (TENs), while exempting retail sellers of TEN service operating before January 1, 2026 from public utility regulation

Requires public utilities to submit TEN service plans to the Public Utilities Commission for approval before constructing thermal energy networks, with plans detailing project costs, construction schedules, service areas, and efforts to obtain federal/state/local incentives

Mandates customer transition plans when converting gas customers to TEN service, including technical assistance, communication plans, incentives to offset building retrofit costs, and protections for low-income customers from inequitable costs

Requires utilities to prioritize TEN siting in areas with aging/leaking gas infrastructure, no existing piped gas, environmental justice areas, or where communities have expressed interest in thermal energy projects

Allows utilities to recover reasonable costs for approved TEN projects through rate cases, but prohibits cost recovery for stranded gas infrastructure except for safety-related decommissioning expenses
