MPSC expands transparent public access to detailed utility performance data

Customer Assistance: 800-292-9555

The Michigan Public Service Commission today unveiled a new web application that gives the public the ability to dive into utility reliability data, allowing customers, advocates, researchers, businesses and any interested person access to a transparent, easy-to-use tool for tracking and analyzing utility performance at a first-in-the-nation level of detail online.

The new application allows a ZIP Code-level view of reliability data for Michigan's two largest electric utilities, DTE Electric Co. and Consumers Energy Co., which combined serve more than 80% of Michigan customers.

Utility customers and other interested individuals can access the new data and maps at the MPSC's GIS Hub Site, where links to other MPSC geographic information system (GIS) maps and applications that provide a growing amount of important energy data to the public can be found. The public can access the data from that page by clicking on "Electric Reliability" or directly at the app's webpage.

Customers, for example, can click on their ZIP Code and find the average amount of time customers in their ZIP Code spend without power, how frequently on average they lose power, and how long it takes on average for their power to be restored. That gives customers the ability to see how their utility performs in their ZIP Code, whether the utility is improving reliability over time, and how that compares to other ZIP codes.

The MPSC's goal of publishing this data in an accessible format is to empower customers by providing quick, easy access to data once previously spread throughout regulatory filings. Providing the data in a transparent way can help identify trends and locate areas seeing disproportionate numbers of outages so that utilities and regulators can address them.

"Michiganders deserve reliable and affordable energy services and transparency into the performance and location of the critical infrastructure that serves them," said Commissioner Katherine Peretick. "We want the MPSC to be a source of accessible information so that customers, community organizations, researchers, businesses and others can engage in the regulatory process with ample data to help inform and shape decision-making."

The data are limited for now to DTE Electric and Consumers Energy electric customers. The Commission is working with other utilities to add their data to expand the breadth of information available.

The new application pairs with other data easily available on the MPSC's website, such as the MPSC's Reports, Forms & Data webpage, which includes other utility data the Commission makes accessible to the public.

In 2025, the MPSC unveiled a publicly available GIS Hub Site for maps focused on where Michigan gets its energy. The maps include utility service areas for all electric utilities in Michigan, as well as maps showing the locations of electric generation facilities ranging from those fueled by natural gas, coal or nuclear power to renewable energy sites including solar, wind and hydropower, and the routes of pipelines transporting natural gas, crude oil and refined petroleum products. The MPSC's transparency efforts also include the MPSC's Quarterly Utility Report webpage, first introduced in 2021, which features data on utility shutoffs, customers who are behind on payments, customers enrolled in payment plans, winter protection plans and alternative shutoff protection plans, the number of customers receiving assistance to help with service restoration, and more. This data is useful for social service providers, local and state governments, consumer advocates and others to help inform policy decisions, but is also available to anyone interested in utility matters.

The MPSC serves as an expert, impartial regulator committed to consumer protection, fairness and transparency. For information about the MPSC, visit www.michigan.gov/mpsc, sign up for its monthly newsletter or other listservs. Follow the MPSC on Facebook, X/Twitter, LinkedIn or Instagram.
