Overview:

  • DTE Energy filed for a $474-million rate increase in April — a 9.7% hike for residential customers — just months after a $242.4-million increase was approved in February.
  • Michigan legislators have introduced bills to limit utility rate hikes to once every three years and tie property tax elimination to rate rollbacks.
  • The Michigan Public Service Commission oversees utility rates, including four pending cases affecting Southeast Michigan residents.

This story is part of a series by Planet Detroit on the environmental and health issues at stake in the 2026 midterm election.

Utility rates in Michigan are a regular source of conflict between utility providers, ratepayers, and regulators. A wrangle over what you pay to keep your home warm or cool involves far more than simply what the utility wants to charge you for it, and overseeing it all is the Michigan Public Service Commission.

Why it matters

Metro Detroit residents could see their electric bills jump 9.7% if DTE Energy's $474-million rate increase request is approved, coming just months after the last rate hike.

Who's making public decisions

The Michigan Public Service Commission, a three-person appointed body, has the authority to approve or reject utility rate increase requests after administrative law judges make recommendations.

What to watch for next

Watch for the MPSC’s ruling on DTE Electric’s pending rate case (Case No. U-22046) and whether Michigan Senate Bill 768, which would limit rate hikes to once every three years, advances out of committee.

Reliability complaints, back-to-back utility rate hike requests and the heated debate over DTE Energy’s power contracts for the Saline Township data center are among the issues keeping the three-person public body in the spotlight this election year.

Bills introduced in the Michigan Legislature would limit utility rate hike requests made to the MPSC to once every three years and tie the elimination of property taxes on utilities to a rollback in rates. 

How Michigan utility rates are set

The MPSC, a three-person public body, regulates privately owned electric utilities, natural gas providers and pipelines, as well as phone and cable providers. Investor-owned utilities, like DTE Energy and Consumers Energy, go before the commission to ask for changes in either their grid or what customers pay to access it. 

To increase rates, utilities bring cases, much like court cases, with the utility as petitioner.

The cases are overseen by administrative law judges, who consider the request and hear from interested parties. It’s up to the administrative law judge to make a recommendation to the commission, which then issues a ruling, which can be appealed. 

Public comments on rate cases can be made using the MPSC’s E-Docket system.

Intervenors in the rate cases, such as Attorney General Dana Nessel and We Want Green Too, file a petition to intervene with the MPSC to become an official party to the case that receives documents and is automatically notified of events. Intervenors are subject to cross-examination before an administrative law judge.

In general, Michigan electric utilities have struggled with their infrastructure for the same reason water systems have – fewer customers paying to maintain a grid built for far more of them, according to MPSC spokesperson Matt Helms.

Then there are trees. And data centers. 

Both DTE Energy and Consumers Energy have been aggressively trimming trees, which are the No. 1 cause of power outages, particularly as seasonal storms become more intense. The Wall Street Journal, in reporting on an aggressive pruning of trees in Ann Arbor, pegged DTE’s spending on this issue at $1 billion over five years. 

Data centers, and their extreme power needs, have emerged as the single most contentious issue in relations between utilities and their customers. 

In April, DTE Energy filed for a $474-million rate increase that was immediately met by a promise to intervene on ratepayers’ behalf by Nessel. 

Nessel said DTE’s request would translate to a 9.7% hike for residential customers, and comes only months after a $242.4-million increase was approved by the MPSC in February.

MPSC legislation, rate cases

In January, state Sen. Kevin Hertel and seven co-sponsors introduced a bill to limit rate hike requests to once every three years. Senate Bill 768 remains in committee.

Michigan House Republicans, as part of a package of bills, would require a rollback of utility rates at an amount equal to the elimination of the utilities’ property taxes. The bills are primarily concerned with property tax issues. The bills have passed the Republican Senate but now face the Democratic-controlled House.

The pending rate cases before the MPSC include four affecting southeast Michigan. They are: 

Consumers Energy Co. (gas), Case No. U-21981

Consumers Energy Co. (electric), Case No. U-22070

DTE Electric Co., Case No. U-22046

DTE Gas Co., Case No. U-21973

Advocacy groups to watch

The Citizens Utility Board of Michigan “represents the interests of residential energy customers” and “advocates for responsible energy infrastructure investment, fair and affordable utility billing, and a cost-effective approach to a cleaner, more efficient grid.”

5 Lakes Energy works with nonprofit, business, and government leaders to “achieve clean-energy solutions and protect consumers.” 

Sierra Club Michigan “has organized the bold action of citizens working together to protect and restore our Great Lakes state’s health and heritage” since 1967.
