No dedicated large-load rate class yet in Maine has no state-specific large-load tariff at this time. Like Connecticut, Maine sits inside the same New England Transmission Owners FERC rate case governing how much data centre-driven transmission investment gets recovered from the regional rate base, rather than through its own dedicated data centre tariff.
Also active in Maine: Maine's low current data centre electricity consumption (among the lowest of any US state) means large-load-specific regulation has not yet been a legislative priority, but the regional FERC transmission cost debate affects Maine ratepayers regardless of whether a local data centre ever locates there.
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 Central Maine Power / Versant Power and the relevant state public utility commission before relying on any figure for a capital decision.
Weighing Maine 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 |
