CMS Energy Corporation (CMS) Business Profile

What it does

CMS Energy is a Michigan energy company led by President and Chief Executive Officer Garrick J. Rochow. It owns Consumers, which supplies electricity and natural gas, and NorthStar Clean Energy, which owns and markets independent power production.

Consumers generates or buys electricity, moves it across its distribution network, and sells it to homes, businesses, and industrial customers in Michigan’s Lower Peninsula. It also buys natural gas, transports it into Michigan, stores it for winter demand, distributes it through local pipes, and sells or delivers it to customers. In 2025, Consumers served 1.9 million electric customers and 1.8 million gas customers, reaching 6.8 million of Michigan’s 10 million residents.

The electricity business uses a mix of company-owned plants, long-term power-purchase agreements and the MISO wholesale market. Its owned generation included gas, coal, hydroelectric, wind, solar and battery-storage assets in 2025. The gas system includes transmission lines, distribution mains, compressor stations and 14 storage fields; gas is injected into storage in summer and withdrawn during winter.

NorthStar Clean Energy develops and operates renewable generation, owns interests in independent power plants, and markets electricity and natural gas through CMS ERM. Management said on the call that CMS Energy plans to exit non-utility renewable development, while retaining Michigan-based assets including Dearborn Industrial Generation, small gas peakers and four commercial solar projects.

How it makes money

CMS Energy earns most of its revenue through Consumers’ regulated electric and gas utilities. The electric utility earns revenue from generating, purchasing, distributing and selling electricity. The gas utility earns revenue from purchasing, transmitting, storing, distributing and selling natural gas. Retail utility rates and certain other business terms are regulated principally by the Michigan Public Service Commission, while FERC regulates specified wholesale, transmission and federal matters.

Consumers’ regulated operations account for the substantial majority of CMS Energy’s assets, income and operating revenue. Rate cases determine recovery for investments and operating costs, subject to regulatory decisions. The company also earns a return on new clean, renewable or energy-storage power-purchase agreements with non-affiliated entities equal to its pre-tax weighted-average cost of capital on permanent capital structure.

NorthStar Clean Energy provides a smaller non-utility revenue stream. Its independent-power-production operations earn revenue from power plants and renewable projects, while CMS ERM purchases and sells energy commodities to support NorthStar’s plants and optimize that portfolio. Management said on the call that, after the planned NorthStar restructuring, nearly 100% of earnings and future growth are expected to be rate-based within the utility.

2025 consolidated operating revenue was $8.5 billion; in the first half of 2026, adjusted net income was $464 million, or $1.50 per share.

Customers and how it sells

CMS Energy operates primarily in Michigan. Consumers serves customers in Michigan’s Lower Peninsula, with a customer base made up primarily of residential, commercial and diversified industrial users. In 2025, it supplied electricity and/or natural gas to 6.8 million Michigan residents through 1.9 million electric customer accounts and 1.8 million gas customer accounts.

Neither the electric nor gas utility depends on one customer or a small group of customers. The company states that losing one or several of its largest utility customers is not reasonably likely to have a material adverse effect on its financial condition. Electric service is sold directly through Consumers’ regulated network. Michigan’s retail open-access program allows customers to buy electric generation from alternative suppliers, subject to an aggregate cap of 10% of Consumers’ sales; deliveries under that program reached the limit at December 31, 2025, although fewer than 300 Consumers electric customers used it.

Management said on the call that the company had contracted roughly 135 megawatts of manufacturing and industrial load year to date in 2026. Management also said an agreement with a large-load customer remains subject to local zoning approval and that the associated load will be included in the integrated resource plan filed in September.

Suppliers and costs

Electric supply costs include fuel for owned plants, purchased power under long-term agreements, MISO market purchases, transmission and distribution operations, depreciation, property taxes, interest expense and investment in reliability and generation. During 2025, Consumers acquired 32 percent of electric supply through long-term power-purchase agreements and the MISO energy market. Commitments under long-term power-purchase agreements were estimated at $17.0 billion from 2026 through 2060 at December 31, 2025, subject to plant availability and fuel costs.

Consumers buys natural gas for electric generation near the time of consumption. For its gas utility, it purchases most gas for full-service customers and contracts for transportation with Panhandle Eastern Pipe Line Company and Trunkline Gas Company, LLC; those planned contract volumes provide 34 percent of forecast 2026 gas-supply requirements. Gas storage helps meet seasonal winter demand: 46 percent of gas supplied to all customers during the 2025 winter months came from storage.

For 2026, CMS Energy projects $4.4 billion of capital expenditures, including $4.1 billion projected by Consumers. The company expects inflation, tariffs, supply availability and pricing to affect its supply chain, and is taking mitigation steps.

Competitive position

No companies are named as competitors in the available information. Consumers faces actual and potential competition in wholesale and retail electricity, generation, electric delivery and retail services. In its service area, alternative electric suppliers can provide generation service under Michigan’s retail open-access program, which is capped at 10% of Consumers’ sales in aggregate, with specified exceptions. It also faces potential competition from customer self-generation, municipal electric delivery systems, data-center expansion or industrial relocation outside its territory.

The gas utility competes with gas-choice and transportation programs, customer bypass of its system, and alternative fuels and energy sources including propane, oil and electricity. NorthStar Clean Energy competes with energy developers, energy retailers and independent power producers. Demand in that market depends on present and projected electricity demand and available generation.

Our reading: Consumers’ municipal franchises, regulated retail rates and physical electric-and-gas networks form a strong barrier in its service territory, but they do not eliminate generation competition because the retail open-access program is at its statutory limit. [item1]

Our reading: The utility’s broad residential, commercial and industrial customer base is a medium-strength advantage because the company is not dependent on a few customers, while self-generation, bypass and alternative fuels remain available. [item1]

Growth opportunities

CMS Energy’s utility investment program, grid reliability work, resource additions and prospective large-load connections are its stated growth avenues. Management said on the call that the foundation of long-term growth is a $24 billion utility investment plan intended to drive 10.5% compounded rate-based growth. Management also identified a $2 billion utility-renewables opportunity associated with the approved Renewable Energy Plan and a $1 billion electric-distribution reliability opportunity in the Reliability Roadmap.

Consumers’ renewable plan includes up to 9,000 MW of purchased and owned solar resources and up to 4,000 MW of wind resources. It has also contracted to buy 850 MW of capacity from battery-storage facilities expected to enter commercial operation through 2028. The company expects its planning to position it for 60-percent renewable energy by 2035 and 100-percent clean energy by 2040.

Management said on the call that an agreement under the large-load tariff includes an extraordinary facilities agreement and a rate agreement, but local zoning approval remains the next step. Management also said the company will incorporate the associated load into its September integrated resource plan. The company expects weather-normalized electric deliveries to increase over the next five years from 2025, with demand growth partly offset by energy-waste-reduction programs.

Management said on the call that NorthStar’s restructuring is targeted for completion by the end of 2026.

Structural risks

• CMS Energy depends on dividends from subsidiaries to meet debt-service obligations. Its ability to pay debt, reduce indebtedness and obtain financing depends on future performance, economic conditions, regulatory decisions and other factors.

• Utility rates, investment recovery and other operations are subject to MPSC, FERC and other regulatory decisions. Parties in regulatory proceedings can challenge policies and practices, seek cost disallowances and appeal orders.

• Consumers’ substantial capital-investment program depends on project cost and schedule management, construction personnel, contractor performance, material and equipment availability, interconnection timing, financing access and regulatory cost recovery.

• The retirement of J.H. Campbell remains subject to temporary emergency orders from the U.S. Secretary of Energy. Consumers continued operating the plant under those orders and is pursuing recovery of related costs through FERC proceedings.

• Environmental rules, permits, litigation and remediation can require additional spending or affect facilities. Consumers expects to seek recovery of compliance costs in rates but cannot guarantee that result.

• Weather can affect customer demand, infrastructure and operating costs. Management said on the call that storms were the primary headwind relative to planned assumptions in the first half of 2026.

Bottom line

Our reading

Our reading: CMS Energy is primarily a regulated Michigan electric-and-gas utility whose earnings, investment needs and customer service are shaped by regulatory decisions; NorthStar is being repositioned so that the company expects nearly all future earnings growth to be utility rate-base driven. [item1; call_prepared]

Our reading: Its operating model combines large, long-lived networks and seasonal energy demand with substantial capital spending, power-purchase commitments, regulatory cost-recovery exposure and weather risk. Potential load growth and renewable, storage and reliability investment sit alongside those constraints. [item1; item1a; item7]
