Grid, generation or storage
Google has committed to investing in 2.7 GW of new generation, including solar — more than twice the facility's 1 GW maximum load. DTE states it will pay for all grid connection and infrastructure costs and that residential rates will not rise as a result.

Every entry carries the source it came from. Where the record gives no date, the entry says so rather than being placed by guesswork.

Where the sources disagree

Van Buren Township publishes a single 1 GW figure. Cleanview splits the campus into three buildings of 704, 231 and 65 MW, which sum to the same total.

Published rather than resolved. Picking a favourite number and printing it alone is how a tracker becomes an opinion.

How this compares to the load DTE Electric already serves

Running at 1,000 MW for a year at 85% capacity factor works out to roughly 7,446 GWh a year. Every household DTE Electric serves used 15,132 GWh between them in 2024. This one site is therefore about 49% of what every home in the territory uses.

Computed, not quoted. No filing states this figure. The denominator is residential sales only — DTE Electric’s total system load, including commercial and industrial customers, is considerably larger, so this is not a share of the whole grid. The capacity factor is an assumption. The arithmetic is 1,000 MW × 8,760 hours × 0.85, against 2024 EIA-861 residential sales.

What DTE Electric customers pay, before and now

Residential rate, 2019

16.11¢

Residential rate, 2024

20.13¢

Change over that period

+25%

Those figures are DTE Electric’s own EIA-861 filings and they cover the whole territory. This page does not attribute any part of that change to Project Cannoli. It could not honestly: the change spans years in which this project did not exist, rates move for generation costs, storm recovery, tree trimming and approved return on equity all at once, and the large-load terms the Commission has approved are written specifically to keep these costs off other customers’ bills. Whether they succeed is an open question in front of the Commission, not a settled fact this site can assert.

What actually did change DTE Electric rates, case by case →

The terms a large load takes service under here

DTE Electric operates under U-21990, approved December 18, 2025. Approved special contracts for electric service to the Saline Township data center, with conditions — a contract-by-contract approval rather than a general tariff.

Contracted demand
Roughly 1,383 MW.
Contract length
A power supply agreement of roughly 19 years, extendable by the customer for a further 20, plus a separate 15-year energy storage agreement.
Conditions imposed
Cost allocation and rate design proposals ensuring future large-load interconnection customers pay their own interconnection costs, plus an administrative fee for further large loads.

The Attorney General's motion to reopen and her separate petition for rehearing were both denied on 27 March 2026. On 17 April 2026 she filed a claim of appeal in the Michigan Court of Appeals, seeking to invalidate the approval as an unlawful ex parte order and to remand the matter for a contested case hearing. The proceeding is not closed.

  • U-22061Still open — not yet decided

    DTE Electric has asked the Michigan Public Service Commission to change its Rate D11 and add a new provision for very large electricity users, such as customers needing more than 100 MW, including a minimum monthly billing amount, administrative fees, a termination fee, and collateral requirements. The Commission has not decided the case; a prehearing is set for April 28, 2026 by video/teleconference. Customers can attend that hearing, file a written comment referencing Case No. U-22061, or file a petition to intervene by April 21, 2026.
