If enacted, Vermont would require large data centers to secure special electric contracts and meet detailed energy, water, environmental, and reporting requirements.
Large data centers would need Commission-approved electric contracts that cover their system costs and protect other ratepayers from data-center expenses.
Data centers would have to limit grid and water impacts through energy planning, renewable resources, emergency-only combustion backup, cooling controls, and water permits.
Data centers would publicly report water, energy, and infrastructure payments, while state agencies would study renewable markets and prepare shutdown rules.
A data center would need an approved large-load service contract with its electric company before receiving service. This applies to facilities that use or can use at least 20 megawatts and provide data processing, hosting, or related services. The Public Utility Commission would have to find that the contract serves the general good, benefits the State and residents, protects the electric system, and meets stated energy and environmental policies. The contract would require the data center to cover its share of electric-service and system costs, make minimum payments based on projected use, provide collateral, manage demand, and address emergencies. Data centers could not take part in specified energy-savings or customer-credit programs. The act would apply to data centers that are not operational when the act takes effect and to smaller operating centers that later expand to meet the 20-megawatt threshold.
Data center owners and operators would have to plan for energy efficiency, renewable power, demand management, and lower-impact cooling systems. The requirements cover proposed and operating data centers subject to the bill, including facilities using water, groundwater, surface water, or combustion-based backup generators. Before seeking a major development permit, an owner or operator would have to study site suitability and consult the electric company and efficiency utility. Combustion-based backup generators could be used only during power failures or other emergencies, while batteries and on-site renewable power would be prioritized when practicable. Water-cooled facilities would generally need closed-loop cooling or a Commission-approved alternative, plus required water, discharge, withdrawal, and water-quality permits. Facilities would have to monitor PFAS in covered discharges and follow water-quality limits. These requirements would apply to covered data centers subject to the bill’s effective-date and expansion rules.
Data centers and state agencies would have to provide regular reports and recommendations about data-center impacts and future regulation. Data centers would report energy, water, and shared-infrastructure payments; state officials would study regional renewable markets and future data-center shutdowns. A data center would begin quarterly reports within three months after becoming operational, and the reports would be open to public inspection. The Department of Public Service would include data-center findings in its annual report only if at least one data center had entered the required electric contract. The Public Utility Commission would accept written public input for its renewable-market report, and the Public Service Commissioner would consult with other officials and interested parties on decommissioning recommendations. The renewable-market report would be due by January 15, 2027; decommissioning recommendations would be due by December 15, 2026; annual impact reporting would begin by January 15, 2028 when the stated contract condition is met.
