100 MW (Xcel) or 25 MW with an 80% load factor and 175,000 MWh annually (Otter Tail) determines which of three distinct Minnesota large-load classes applies: Xcel's approved Large General Time of Day Service for 100 MW-plus customers, Otter Tail's Super Large General Service for 25 MW-plus greenfield loads meeting strict load-factor and annual-usage tests, or Minnesota Power's newly proposed Very Large Power (VLP) customer class and service tariff filed July 15, 2026.
Also active in Minnesota: Xcel is serving a 1,000 MW Google campus in Pine Island projected to deliver $1.1 billion in net benefits to other customers over 15 years, and Minnesota Power is serving a 1,000 MW Google project in Hermantown that includes 700 MW of new clean energy resources built without raising customer costs.

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 Xcel Energy / Minnesota Power (ALLETE) / Otter Tail Power and the relevant state public utility commission before relying on any figure for a capital decision.
Weighing Minnesota 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 |
