Large loads connecting to New York's transmission and distribution grid are the subject of a new proceeding the New York Public Service Commission launched in February 2026 to execute Governor Hochul's Energize NY Development initiative — reviewing interconnection processes, cost-allocation mechanisms and tariff structures so that large loads pay their fair share of grid upgrade costs rather than shifting them to other ratepayers.
Also active in New York: As of January 2026, NYISO's interconnection queue held 48 large-load projects totalling more than 11 GW of new demand. In June 2026, FERC directed NYISO to show cause why its tariff should not be found unjust and unreasonable for failing to adequately address large-load interconnection — with tariff revisions targeted for NYISO Board approval and FERC filing by December 2026.
Named Projects Already Underway

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 Con Edison / National Grid / NYSEG (statewide PSC proceeding) and the relevant state public utility commission before relying on any figure for a capital decision.
Weighing New York 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 |
