No dedicated large-load tariff; policy debate currently centred on moratoria has not adopted a large-load tariff. Vermont is one of the states actively weighing a moratorium or added restriction on new data centre development, reflecting concern over the electricity cost and grid impact of large loads rather than a cost-recovery rate structure.
Also active in Vermont: Vermont's current data centre electricity consumption is among the lowest of any US state, and its small, hydro-and-renewables-heavy grid makes the cost-shifting risk from a single very large load proportionally larger than in bigger states — a likely driver of the moratorium conversation.
Figures compiled from the Edison Electric Institute's "Large Load Projects and Tariffs" (September 2026) member-company summary and public regulatory filings. Confirm current tariff terms directly with Green Mountain Power and the relevant state public utility commission before relying on any figure for a capital decision.
Weighing Vermont against another state or a Canadian province with a different rate and interconnection picture entirely? Run both sides of the comparison through our licensed AI data centre cost configurator — it applies each jurisdiction's actual power rate, tax treatment and large-load tariff rules to the same seven build configurations.
Model This State on Your Own Site
Every figure above comes from the same power-cost and tariff dataset behind the SCR AI Build Configurator — a licensed, embeddable widget that models seven data centre build configurations against all nine Canadian provinces and all 50 US states plus DC, returning capital expenditure by line item, energy cost, revenue by commercial structure, EBITDA and payback.
| Licence | Price (CAD) | Who it suits |
|---|---|---|
| Standard | $4,000 / domain / year | Advisors who need three lease-model configurations and a clipboard summary |
| Pro | $10,000 / domain / year | Consultants who send CSV deliverables to clients and want all seven configurations |
| Enterprise | From $25,000 / year, up to 3 domains | Developers and EPC firms who want the model on their own cost basis with attribution removed |
