Data centre and large power load addressed across three separate Michigan utility tariffs is covered by amendments to Consumers Energy's Rate GPD specifically to adjust for data centre load, DTE's proposed revisions to Rate Schedule D11 adding conditions of service for large load customers, and Indiana Michigan Power's approved modifications to its Large Power Tariff (Tariff LP).
Also active in Michigan: Michigan's live projects include a $7 billion, 1,400 MW OpenAI/Oracle/Related Digital campus in Saline Township — expected to generate $300 million a year in affordability benefits for existing customers once fully ramped — and a Google campus in Van Buren Township projected to contribute $1.7 billion in affordability benefits over the life of its contract.

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 Consumers Energy / DTE Energy / Indiana Michigan Power and the relevant state public utility commission before relying on any figure for a capital decision.
Weighing Michigan 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 |
