The bill applies to any facility using 20 megawatts or more of power for data processing and hosting. That threshold captures the large-scale operations that have been at the center of grid capacity debates nationally, while leaving smaller facilities outside the regulatory framework.
The core mechanism in H.727 is a "large load service equity contract" that any covered data center must enter into with its electric distribution company, subject to approval by the Public Utility Commission. The contract must run for a minimum duration and obligate the data center to pay costs proportional to the grid infrastructure needed to serve it. The intent is direct: prevent other ratepayer classes from absorbing the infrastructure costs that large loads require.
Before any site preparation or construction can begin, data centers would need a certificate of public good from the Commission. That process requires findings across 14 criteria, including grid reliability, environmental impact, consistency with state energy and transmission plans, environmental justice policy, and economic benefit to Vermont residents. The list is broad enough that the approval process will carry real weight.
On the operational side, covered data centers would submit quarterly reports on water and energy usage, including peak daily consumption and payments toward shared infrastructure. The reporting requirement is notable because water use has become a meaningful concern in data center siting debates, particularly around cooling systems. The bill requires closed-loop cooling where feasible and prohibits the discharge of PFAS compounds into Vermont waterways.
The bill was moved from Senate Finance to Natural Resources and Energy on Friday, April 17, on the motion of Senator Cummings. That committee is now holding three consecutive days of hearings beginning April 22. The bill is at roughly the midpoint of the legislative process, having passed the House and now working through Senate committee review.
The legislation was introduced by Representative Sibilia of Dover and has proceeded as an independent bill rather than along strict party lines. Vermont is not a state where large data center development has been particularly active relative to major hub markets, but the bill is being watched by industry and policy observers in other states where the grid impact question is already acute.
For technology and digital operations leaders evaluating site selection or tracking the regulatory landscape, Vermont's approach is worth understanding. The combination of mandatory equity contracts, siting approval requirements, and water use restrictions represents a more comprehensive framework than most states have attempted.
