Clean Heat Standard

On May 24, 2023, Act 18 of 2023 became effective. The Act states that “it is the intent of the General Assembly that the Clean Heat Standard be designed and implemented in a manner that achieves Vermont’s thermal sector greenhouse gas emissions reductions necessary to meet the requirements of [the Global Warming Solutions Act of 2020], minimizes costs to customers, protects public health, and recognizes that affordable heating is essential for Vermonters.”

Act 18 directs the Vermont Public Utility Commission (“Commission”) to design a potential Clean Heat Standard and to file its recommendations with the Vermont General Assembly by January 15, 2025. This website is an informational resource for public use designed to share information, increase understanding, and encourage public involvement in this process. The Commission encourages everyone to participate in these proceedings by submitting public comments, becoming a participant and contributing to ongoing discussions, and attending workshops. Your perspective and ideas will help the Commission best design the proposed rule.

The Commission intends for this website to help centralize and simplify publicly available information related to the design of the potential Clean Heat Standard. All materials on this page are for informational use only. Orders, which are documents signed by the Commissioners and issued by the Clerk of the Commission, are the official means of communicating the Commission’s decisions. We will provide links to all Orders on this website. In addition, all Orders, and all forms of stakeholder and public input, can be found on the Commission’s online filing and case management system, ePUC.

Proceeding Structure – At present, the Commission plans to complete its Act 18 work in three cases: 23-2220-RULE and 23-2221-INV, as explained above, and a yet-to-be-opened case for the solicitation, review, and appointment of at least one Default Delivery Agent.

Using Topic Tags – The Clean Heat Standard cases have and will continue to generate a large number of documents. To make these cases more navigable in ePUC, the Commission has created a topic-labeling system as explained in this Order.

How to Get Involved – The Commission welcomes all feedback related to the design and implementation of the potential Clean Heat Standard. To have your voice heard by the Commission, please file public comments or request to be made a participant in either or both cases (23-2220-RULE, 23-2221-INV). Feedback is most helpful when it is specific (related to a distinct aspect of the Commission’s work), actionable (provides a suggestion on what the Commission should do to address a concern), and timely (is submitted during a request for comments on the topic or before the Commission addresses the topic). If you only want to be notified of new filings and orders in the case(s), you can alternatively “subscribe” to the proceeding(s).
