Vermont (VT) data center power coverage
Real, sourced large-load tariff and interconnection research on file for Vermont — never inferred, never scraped, never implied beyond what's actually been checked.
Large-load tariffs
Vermont distribution utilities (Green Mountain Power, others) -- H.727 pending
Threshold20 MW and above (H.727 definition); GMP Rate 70 applies above 10 MW at transmission voltage
StatusBill H.727 (Vermont Sustainable Data Centers Act) as amended by the Senate would require covered facilities (20 MW+) to sign a PUC-approved large load service equity contract with their utility, with minimum payments, collateral against stranded costs, and demand-side management, instead of a tariff. Final passage was not confirmed in the sources found. Existing GMP Rate 70 is available to transmission-served customers above 10 MW, who pay for needed transmission upgrades.
SourceVermont Legislature H.727 documents and Dept. of Public Service testimony (legislature.vermont.gov); passage status unverified.
Interconnection & regulatory guidance
Vermont — H.727 Sustainable Data Centers Act passed both chambers in amended form but was vetoed; no current statutory mandate
Contact guidanceNo enacted statutory large-load tariff or siting regime currently applies as a direct result of H.727 -- the bill's substance is still a useful signal of where Vermont policy is headed, but confirm current status directly since veto fights sometimes end in an override or a revised bill the following session.
ThresholdH.727, as passed, applied to any facility using 20 MW or more of power for data processing/hosting.
ProcessThe House-passed version directed Vermont's Public Utility Commission to create a separate ratepayer class and tariff schedule for data centers. The Senate amended this to instead require a 'large load service equity contract' between a covered facility and its electric distribution company, subject to PUC approval -- requiring minimum usage-based payments, collateral against stranded-cost risk, and demand-side management commitments (demand response, load shifting, peak shaving). The bill ultimately passed in this amended form but was vetoed.
