An act relating to thermal energy networks

This bill establishes the Thermal Energy Network Act to bring thermal energy distribution systems under the oversight of Vermont's Public Utility Commission. It defines thermal energy networks as infrastructure that transfers heat from noncombustion sources to buildings for heating, cooling, and hot water, and grants the Commission authority to regulate companies operating these systems. The legislation requires a certificate of public good before any private provider can build a network serving more than 20 customers, while municipalities retain the ability to operate such networks without Commission approval. The Public Utility Commission must develop permitting rules by July 2025 that prioritize serving low and moderate-income customers, ensure simple and expeditious approval processes, and allow pilot projects.
