PUC chair briefs House Energy panel on siting, rates and regulatory tools

Ed McNamara, chair of the Public Utilities Commission, told the House Energy and Digital Infrastructure Committee on Jan. 21 that the commission regulates retail rates, siting, interconnection and other utility functions and that “the underlying concept is that they need to be regulated to promote the public interest.”

McNamara gave a broad overview of the PUC’s structure, funding and core responsibilities and described how the commission reviews generation and transmission projects under Vermont’s certificate-of-public-good process known as Section 248. “We have to find that the project promotes the general good,” McNamara said, describing the commission’s ability to weigh benefits and harms in its review.

Why it matters: the PUC’s interpretations affect how utilities recover costs, how renewable and storage projects are sited, what consumers pay for service and which local concerns are considered in state-level approvals. McNamara emphasized that the commission’s decisions shape rates, reliability and long-term planning that affect households, businesses and municipal systems across Vermont.

McNamara summarized the PUC’s structure and budgetary sources: the commission is composed of three commissioners serving staggered six-year terms and is funded chiefly by a gross receipts tax paid by regulated companies, which he said accounts for roughly 93% of the agency’s budget. He said application fees and “build back” fees for one-off costs make up small portions of revenue and that the PUC maintains a reserve fund to smooth year-to-year variation in receipts.

On siting and contested cases, McNamara described Section 248 (the certificate-of-public-good process) as a quasi-judicial review that incorporates environmental criteria and system impacts. He said the PUC examines aesthetics using the Quechee test and can deny projects that would have an “undue adverse effect” on environmental or reliability criteria. He also noted that the commission may balance specific harms against broader public benefits, but that such balancing is “not done very often.”

McNamara explained two key federal exceptions where states retain authority: net metering and qualifying facilities under the Public Utility Regulatory Policies Act (PURPA). He said many generators participate in wholesale markets administered by ISO New England and regulated by the Federal Energy Regulatory Commission, but that long-term power purchase agreements remain common and affect pricing.

On planning and cost recovery, McNamara described Vermont’s integrated resource planning requirement: electric utilities and Vermont Gas must file an integrated resource plan at least every three years that looks out to roughly 20 years. He said the statutory “least-cost planning” standard requires the PUC to include environmental costs — including greenhouse gas considerations — when evaluating resource choices.

McNamara also reviewed customer-facing rules and programs: net-metering registrations for small rooftop systems (a 10-day registration window for utilities to object), interconnection rules to prevent damage to the grid, energy-efficiency programs (run statewide by Efficiency Vermont except for Burlington Electric Department, which runs its own program) funded by an energy-efficiency charge, and disconnect rules with protections for cold weather and medical reasons.

On telecommunications and cable, he said the PUC’s authority is limited: the commission regulates certain wired telephone service quality, designates eligible telecommunications companies and administers a lifeline program for low-income telephone customers, and it grants cable franchises for providers such as Comcast while largely deferring rate and channel decisions to federal law. He described broadband and most wireless services as largely outside the PUC’s regulatory authority.

McNamara addressed cost-causation issues for grid upgrades and line extensions. He said the PUC generally requires utilities to evaluate whether projected increased revenues from added load (for example, from electric vehicle charging or snowmaking) exceed upgrade costs; if the incremental revenues cover the upgrade, those costs are typically socialized across ratepayers. He contrasted that with generation interconnections, where the “last person in” typically bears interconnection costs.

The presentation included administrative details: the PUC uses an electronic case management system (EPC/EPUC), has a clerk and deputy clerk to manage filings, uses hearing officers for many cases and staff that McNamara described as including attorneys, analysts and operations personnel. He said contested siting cases usually include evidentiary hearings, cross-examination and a formal ex parte prohibition; uncontested rulemakings and workshops are more informal.

McNamara closed by inviting committee members to follow up on specific topics and offered to return with deeper briefings on complex subjects such as wholesale market rules administered by ISO New England. Committee members asked questions on how the PUC applies the Quechee aesthetics test, how integrated resource planning works in practice and the PUC’s jurisdiction over third-party electric vehicle charging stations and broadband services.

Looking ahead, McNamara said decisions by the commission are final and subject to appeal to the Vermont Supreme Court, and he urged lawmakers to reach out with targeted questions when the committee wanted deeper dives into specific rules or processes.
