FactVote reviewed summary
The final version of H.727 passed by both chambers would require Public Utility Commission approval of electricity contracts for covered data centers using or able to use at least 20 megawatts. It would apply to centers not operational on the act’s effective date and existing centers below 20 megawatts that expand to meet the threshold. Contracts would allocate service costs to the center and insulate other ratepayer classes from deployment costs, including new infrastructure, capacity and resource adequacy costs. The governor vetoed the bill, and the House sustained the veto on May 29, 2026. These proposed protections were not enacted.
Veto of the Governor sustained by a vote of Yeas = 83, Nays = 52. Not enacted.
Why this record is included
The electricity fact measures the average retail price across all customer sectors. Allocating data-center infrastructure and energy costs concerns the utility-rate component of that price. The vetoed proposal establishes no actual rate change or savings. This relationship does not establish causation. Actions after the measurement period cannot explain its earlier value.
Retained Vermont evidence context: Average retail electricity price. This record’s connection to the topic does not establish an effect on the measured result.
(1) “Data center” means a facility that uses or is able to use 20 megawatts or more of power and is engaged in providing data processing, hosting, and related services as described under code 518210 of the 2022 North American Industry Classification System. […] § 284. LARGE LOAD SERVICE EQUITY CONTRACT; APPROVAL (a) For the purpose of ensuring just and reasonable rates for all ratepayer classes and precluding the risk of financial exposure to electric companies and their existing ratepayers, a data center shall be served by an electric company pursuant to a large load service equity contract approved by the Public Utility Commission. (b) The large load service equity contract shall: (1) include a method for allocating costs that is equal or proportional to the costs of providing electric service to the data center, including providing for equitable contributions to the embedded costs and the stability, efficiency, reliability, and resiliency of the electricity network; (2) ensure that other ratepayer classes are insulated from all costs associated with data center deployment, including expenses for new generation, transmission, and distribution infrastructure, as well as energy capacity and resource adequacy costs; […] Sec. 6. EFFECTIVE DATE; APPLICATION This act shall take effect on passage and shall apply to any data center not operational on the effective date of this act as well as to any data center that uses less than 20 MW of power that is operational on the effective date of this act to the extent such data center seeks to expand its capacity and meet the threshold requirements of Sec. 1, 30 V.S.A. § 283(1).Review official supporting evidence ↗
