Public utilities in Michigan are regulated by the Michigan Public Service Commission (MPSC).
* **Electricity & Natural Gas:** The state's energy grid is primarily managed by two major investor-owned utilities: **DTE Energy** (serving primarily Southeast Michigan) and **Consumers Energy** (serving much of the rest of the Lower Peninsula). The Upper Peninsula is served by regional providers like UPPCO. * **Water & Sewer:** Municipalities generally handle water services. The **Great Lakes Water Authority (GLWA)** is a massive regional authority providing water and wastewater services to nearly 40% of the state's population (primarily in Metro Detroit). * **Waste Management:** Handled locally through municipal contracts and private companies, with major operators including Waste Management (WM), GFL Environmental, and Granger. * **Telecommunications:** Widespread broadband and cellular coverage is provided by national carriers (AT&T, Comcast Xfinity, Charter Spectrum), though rural broadband access in northern Michigan and the Upper Peninsula remains an ongoing development focus.
