Michigan has shown how a hyperscale data center can pay for itself.
On October 1, the Michigan Public Service Commission unanimously approved special contracts between DTE Electric and Google to supply power to a 1 gigawatt data center in Van Buren Township, Wayne County. The approval came with conditions designed to keep the project’s costs off the bills of DTE’s other customers.
The deal pairs a primary supply agreement with a clean capacity accelerator agreement. Under the second contract, Google pays DTE to develop up to 1,600 megawatts of renewable energy and 480 megawatts of battery storage to serve the site. DTE will own and operate those resources. According to the commission, the data center is expected to begin taking service in December 2027 and reach its maximum load by December 2028.
The headline number is the gigawatt. The more important part is how the contract is built.
The Contract Terms Do the Heavy Lifting
Large-load approvals have become one of the hardest steps in data center development. Regulators want the investment and the jobs, but they also have to answer to residential and small business customers who worry about paying for grid upgrades built for someone else.
The Michigan commission answered that concern in the contract terms. According to the MPSC, the agreements run for 20 years, compared with the five-year terms typical of DTE’s standard large industrial rate. Google must pay for at least 80% of its contracted demand each month, even if it uses less, well above the 50% to 65% minimums common under standard tariffs. If Google leaves early, a termination payment requires it to cover minimum charges for at least 15 years. Credit and collateral requirements add another layer of protection in case the facility stops operating.
Commissioner Shaquila Myers put the principle plainly, according to the Detroit Regional Chamber: “Existing ratepayers should not be asked to subsidize the infrastructure required to serve a new data center.”
Commissioner Katherine Peretick framed the core question of the case in similar terms, as reported by Planet Detroit: how to make sure that existing customers are protected.
That question now has a written answer.
A Large Load Can Lower Costs for Everyone Else
The usual story about data centers and utility bills runs in one direction. Here, DTE argues the effect runs the other way. The utility says the contracts will produce a $1.7 billion benefit for other customers over the 20-year life of the agreement, because Google will carry a share of fixed grid costs that would otherwise be spread across the rest of the rate base.
That is the strongest economic argument a utility can make for a large load. A gigawatt customer paying high, predictable minimum charges for two decades spreads the fixed cost of the system across far more kilowatt-hours.
The argument only holds if the customer actually stays and pays. That is why the 80% minimum bill, the 15-year exit payment and the collateral matter so much. They turn a forecast benefit into something closer to a contractual one.
Not everyone thought the terms went far enough. Planet Detroit reports that Attorney General Dana Nessel pushed for a 90% minimum billing demand, citing the risk of stranded assets if the facility is underused or closes early. The commission settled on 80%, which still sits well above standard industrial terms.
Clean Capacity Arrives With the Load
The clean capacity accelerator agreement is the second half of the model, and it may prove the more widely copied one.
Rather than buying credits or signing a remote power purchase agreement, Google funds new renewable generation and storage that DTE builds and runs on its own system. The 1,600 megawatts of renewables and 480 megawatts of batteries are sized against a 1 gigawatt load, which gives the utility room to manage the intermittency of wind and solar while still adding real capacity to the Michigan grid.
For utilities, this structure keeps generation inside the regulated system they already know how to plan and operate. For hyperscalers, it ties new load directly to new supply, which is increasingly what regulators and communities expect to see before they say yes.
Who builds the new capacity?
Who pays for it?
In Michigan, the answers are now in the same contract.
What Developers and Utilities Should Take From Van Buren Township
Planet Detroit describes the case as Michigan’s first hyperscale data center contract decided through a full contested case process. That makes the record useful well beyond Wayne County. Other states are working through the same questions, and a completed approval with clear numbers gives developers and regulators a reference point.
The terms that carried this approval are worth studying closely:
- Contract length that matches the life of the assets being built
- Minimum billing demand well above standard industrial tariffs
- Exit payments covering a long minimum period of charges
- Credit and collateral sized to the risk of a site going idle
- Customer-funded generation and storage owned by the utility
- A quantified benefit case for existing ratepayers
None of these items is exotic. Together, they shift the risk of a large load from the utility’s other customers to the company that creates the demand. Hyperscalers with strong balance sheets can carry that risk. The approval suggests regulators will increasingly ask them to.
For investors, the signal is also positive. A data center with a firm, regulator-approved power path and a defined in-service date of December 2027 is a far more bankable project than one waiting in a queue for an uncertain decision.
Speed Comes From Settling the Cost Question Early
Power availability is usually described as an engineering constraint. In practice, much of the delay comes from unresolved arguments over who bears the cost and the risk.
Michigan’s decision shows how to shorten that argument. When the large customer agrees to pay for its own load, fund new clean capacity and post security against an early exit, regulators have a clear basis to approve. The site also has local backing: the Wayne County Commission overrode an executive veto to approve a tax exemption worth more than $125 million for the project, according to Michigan Public.
The next test is execution. DTE has to bring up to 1,600 megawatts of renewables and 480 megawatts of storage into service on a schedule that keeps pace with a load ramping toward full capacity by the end of 2028. That is a substantial build on a tight timeline.
That makes delivery the measure of success.
The gigawatt will draw the attention. The contract terms are what other states are likely to copy.
