Michigan regulators have approved power contracts between DTE Energy and Google for a planned 1-gigawatt data center in Van Buren Township, clearing a major regulatory hurdle for the Project Cannoli campus.
The Michigan Public Service Commission (MPSC) approved the agreements on October 1, 2026, allowing DTE to move forward with the special power arrangements needed to serve Google’s planned facility.
The project calls for a data center campus of nearly 1.5 million square feet on approximately 282 acres near Haggerty Road and Interstate 94.
The approval comes as new electric infrastructure is being planned specifically for the development, including a 345-kilovolt switching station and two high-voltage transmission feeds.
DTE to Serve Google’s 1 GW Campus
DTE and Google entered into a 20-year Primary Supply Agreement and a related Clean Capacity Accelerator Agreement for the project.
Under the proposed power arrangement, the facility is expected to begin taking electricity in December 2027 and reach its maximum contracted load of approximately 1 GW by December 2028.
DTE’s regulatory filings describe 1 GW as the facility’s maximum load or contract capacity. The figure represents the amount of electricity the customer has contracted for rather than current electricity consumption.
The project will receive service under DTE’s Rate D11, a rate structure that applies to large electricity customers.
The long-term agreement also establishes financial requirements intended to assign project-related electricity costs to Google rather than DTE’s existing customer base.
Google is required to maintain a minimum billing demand equal to 80% of its contracted capacity, according to the terms presented in the regulatory proceeding.
The agreement also includes provisions addressing costs if the facility terminates service before the end of the contract.
Project Requires New 345-kV Transmission Infrastructure
The data center will require significant grid infrastructure beyond the facility itself.
ITCTransmission is developing Project Cannoli’s transmission connection, including a new 345-kV switching station and two 345-kV transmission feeds.
The feeds will connect the proposed Cannoli switching station to ITC’s existing Brownstown-Wayne No. 1 and Brownstown-Wayne No. 2 345-kV transmission lines.
ITC expects the first transmission feed to enter service in late 2027, followed by the second in late 2028.
Construction of the switching station is scheduled to begin in the first quarter of 2028, with completion targeted for the third quarter of 2028.
The transmission work will provide the high-voltage connection needed to deliver power to the large-load customer as the data center campus comes online.
Agreement Includes Renewable Energy and Battery Storage
The power arrangement also links Google’s electricity demand to new clean-energy and storage resources.
DTE’s agreement provides for Google to fund development of up to 1,600 MW of renewable generation and 480 MW of battery storage.
DTE is also required to account for the additional data center demand in its resource planning.
The arrangement is intended to increase generation and storage resources as the utility prepares its system for the new large electricity load.
Google previously said it would support additional energy resources and infrastructure associated with the project while working with DTE on the electricity requirements for the campus.
Project Cannoli Advances Toward Construction
The MPSC decision represents a major state-level milestone, but the data center still faces additional development steps before construction can proceed.
The proposed campus is located on the east side of Haggerty Road near I-94 in Van Buren Township.
The development has been moving through local planning and approval processes while the power contracts were under regulatory review.
The Wayne County Commission also voted October 1 to override County Executive Warren Evans’ veto of tax incentives for the project, according to local reporting. The county action followed months of debate over the proposed development and its public costs.
The township’s planning process remains another important step for the project.
Google’s Michigan Data Center Expands Hyperscale Development
Google confirmed in March that it was behind the Van Buren Township data center proposal and was working with DTE on the infrastructure needed to support the development.
The campus would become one of Michigan’s largest proposed data center developments, with a contracted electricity requirement comparable to the power demand of a major industrial facility.
The combination of the data center, dedicated transmission infrastructure, renewable generation and battery storage also makes Project Cannoli a broader power-infrastructure development rather than a standalone building project.
With the MPSC approval now in place, DTE and Google have cleared a key regulatory step toward connecting the planned campus to Michigan’s electric grid.
Project Cannoli is one example of how major technology developments are driving new investment in power infrastructure. A similar trend is emerging in Maryland, where Constellation and Amazon are backing more than $3 billion in upgrades and capacity expansion at the Calvert Cliffs nuclear plant, including approximately 190 MW of additional emissions-free generation.
