Why Are Michigan’s Energy Prices So High? An Introduction to Cost Drivers, Emerging Issues, and Utility Regulation in Michigan

This webinar equips utility customers, business leaders, and community stakeholders with a foundational understanding of how electric utilities are regulated in Michigan, what is driving recent rate increases, and where the energy system is headed as electricity demand accelerates.

The expert panel explores how utilities are regulated in the state, the factors that have historically driven local markets, and what sustainability professionals and business leaders should know about current events. 

Learning Objectives:

• MPSC 101:  Understand how the Michigan Public Service Commission regulates utilities in the state, including the process by which utility rates and standards are determined and its unique community of attorneys and advocates.
• Identify perceived and real influencers of energy costs in Michigan, from renewable energy portfolio standards to foreign wars.
• Discuss potential impact of hyperscale and conventional data center development to electric demand in the state. 
• How to source renewable energy and evaluate clean energy and energy efficiency opportunities in the current landscape.

Speakers: 

• Erik Nordman, Associate Professor and Director of the Institute of Public Utilities at Michigan State University
• Mike Troupos, Vice President, Foresight Management

How Utility Regulation Works

Electric utilities are considered natural monopolies. High fixed costs, high barriers to entry, and low marginal costs mean one firm can typically serve a territory more efficiently than several competing ones. In exchange for the exclusive right to serve, utilities agree to be regulated rather than let the market set prices. Michigan’s investor-owned utilities, DTE and Consumers Energy, handle generation but not transmission.

State public service commissions, including the MPSC, act as quasi-judicial bodies that review utility rate requests through a structured process: determining the total “revenue requirement” to deliver service, allocating these costs fairly across residential, commercial, and industrial customer classes, and designing the actuarial rate structure. Because utilities use private shareholder capital to fulfill their public obligation to serve, shareholders are entitled to a reasonable return on that investment. This means that rates can be “fair and equitable” while still being unaffordable for lower-income households.

Michigan Rates are Rising

Nationally, the leading driver of electricity price increases is fuel and wholesale supply costs, followed by distribution costs and generation capital investment. In Michigan specifically, a 2024 third-party audit of DTE and Consumers Energy conducted by MPSC tied poor reliability to aging infrastructure including circuit breakers dating as far back as the 1930s, overgrown vegetation near powerlines, and a patchwork of low-voltage distribution lines left over from utility mergers. Consumers Energy requested a $436 million rate increase in 2025 (of which $276 million was approved), then returned roughly 12 months later requesting another $456 million. A revised model of building in response to use combined with expanding the regulatory lag period between rate cases could help ease the pressure.

Who’s Responsible, and What’s Changing Nationally

Responsibility for high rates is described as spread across multiple actors: federal policy has limited direct influence since electricity is regulated at the state level; state renewable energy standards have some upward effect on rates but deliver public health benefits; state utility commissions approve or disallow utility spending requests; and utility company incentive structures can reward large capital investments over cost containment. 

After roughly two decades of per-capital electricity consumption (1990-2020) flat-lining due to lighting and appliance efficiency gains, demand is now climbing as a result of growing AI data centers, growing electric vehicle adoption, and the broader electrification of the economy. U.S. total gasoline consumption is believed to have peaked in 2019. At the same time, decades of underinvestment in aging grid infrastructure at the expense of greater shareholder returns has left utilities needing to catch up on maintenance just as demand is rising. 

The Path Forward for Generation

Natural gas remains the largest single source of U.S. electricity generation, but renewables are an increasingly significant part of the mix: solar generation reportedly surpassed coal generation for a month in early 2026, and roughly 40 percent of U.S. electricity now comes from low-carbon sources when combining renewables and nuclear. Wind and solar energy nonexistent fuel costs make them increasingly cost-competitive as technology costs continue to fall.
