No dedicated large-load tariff in Rhode Island has not introduced a state-specific data centre tariff. Rhode Island ranks 7th nationally for overall utility costs, and — like the rest of New England — is affected by the regional FERC transmission return-on-equity dispute tied partly to data centre-driven grid investment, rather than a dedicated in-state large-load rate class.
Also active in Rhode Island: With minimal current data centre load and high existing electricity costs, Rhode Island has not emerged as a priority hyperscale siting market, though its position inside the New England grid means transmission cost decisions made regionally still apply.
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 Rhode Island Energy and the relevant state public utility commission before relying on any figure for a capital decision.
Weighing Rhode Island 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 |
