Michigan Electricity Rates per kWh: DTE, Consumers and Summer Peak Prices

Consumers Energy’s last increase began in May 2026. It filed for the next one on 2 June, the first day it could. DTE did much the same. We lay out the run of cases, what a peak-hour change is really worth, and where the money fight goes next.

One rate case after another

Michigan’s utilities now file about as fast as the law allows. Consumers Energy filed on 2 June 2026, just weeks after its previous increase started, and it had said in advance that this was the first day it was eligible. DTE filed its latest request two months after its last approval. Here is the recent run.

Those DTE steps come to about $16 a month in barely over two years, on typical bills using the Commission’s figures. The 2025 and 2026 figures use a 500 kWh home; the 2023 one is the Commission’s typical bill. Regulators keep granting less than requested: $242.4 million against DTE’s $574.1 million ask in the last case, and $276.6 million against Consumers’ $423 million.

Attorney General Dana Nessel has told the Commission DTE deserves no more than $134.5 million, which would cut the residential increase from 10% to 2%, and has asked for Consumers’ to be cut by more than half. A Consumers decision is due by April 2027.

What moving a dishwasher load actually saves

Most DTE and Consumers homes are on a time-of-day rate by default. From June to September, Consumers charges 24.5¢ per kWh from 2 to 7 p.m. on weekdays and 19.7¢ off-peak, a gap of 4.8¢. DTE’s peak is 3 to 7 p.m. at about 24¢, against about 18.4¢ off-peak in the most recent figures we found.

So what is it worth? The average Michigan home used 914 kWh in July. Move 100 kWh of that month out of the window and a Consumers home saves $4.80. Running a dishwasher and dryer after 7 p.m. may get you there; running air conditioning is harder, so pre-cooling before 2 p.m. does more. Over four summer months, 100 kWh a month is worth about $19.

Against the $4.93 to $6.46 a month from this year’s increases, that is roughly one rate case offset, but only during summer. The peak does not apply outside June to September or at weekends.

A price for the calculator

Because time of day moves the average from month to month, use your bill’s total divided by its kWh. Or choose your utility for what its homes paid in 2025.

The Upper Peninsula, Holland and the rest

DTE’s homes paid 20.25¢ per kWh all in during 2025 and Consumers’ 20.66¢. Those two prices are close; the sharp gaps sit at the map’s edges. Upper Peninsula Power charged 27.98¢, the highest of any Midwest utility with 20,000 or more homes, while the co-op Cloverland, in the eastern U.P., charged 14.27¢. In the southwest, Indiana Michigan Power charged 17.19¢.

The lowest price is Holland’s Board of Public Works, at 11.43¢, and Lansing’s Board of Water & Light charged 19.44¢. City utilities and most co-ops set their own rates, so the cases above do not reach them.

EIA-861 for 2025: each utility’s revenue from homes divided by the kWh they used, so monthly charges are spread into the price.

A 10% cap keeps homes out of the market

Michigan opened to alternative suppliers in 2002 and largely closed again in 2008. Public Act 286 caps them at 10% of each utility’s sales. Businesses and schools filled that long ago and newcomers join a queue, so the rate cases are the only real check for most households. In the federal data only a handful of homes buy from anyone but their utility.

Data centers enter the rate fight

A newer argument hangs over both cases. The Commission approved a Consumers data center tariff on 6 November 2025. In DTE’s open case, the Attorney General wants a separate rate class for large data centers, with their extra generation and grid costs assigned directly to them. Her office says that when pressed on whether its cost allocation prevents cost shifting, DTE called the term unclear and ambiguous.

A sharp July on a low base

Bills ran from $106 in October to $211 in July. Use ranks 43rd of 51, so the bill is 35th though the price is 13th. The state’s average price also climbs through the year, from under 20¢ in winter to about 23¢ in summer, as the peak rates apply.

The smoothest climb in the data

Up 71% since 2010, from 12.46¢ to 21.28¢, and never by as much as 8% in a month. That evenness is the point: this rise came through a long run of rate cases rather than fuel shocks. The record month is 23.05¢ in July 2026, and Michigan has been above the US average every year since 2010.

Dearest in the Midwest

Ohio, Indiana, Illinois and Wisconsin all paid less per kWh, as did every state west of them in the Midwest.

Across the border: Indiana 16.90¢, Ohio 18.42¢, Wisconsin 18.79¢.

Figures that differ between sources

For March 2026, the Commission’s $4.93 at 500 kWh differs from DTE’s own $4.23 estimate; we use the Commission’s. DTE’s off-peak rate of about 18.4¢ comes from 2024 and 2026 press reports that used the same numbers, and CBS Detroit gave its peak as about 24¢ in June 2026, so check your own bill. Our 100 kWh example uses Consumers’ published rates. We could not read the open cases’ final residential dollar figures. EIA’s latest months are preliminary.
