The company's history dates back to 1886, when William Augustine Foote and Samuel Jarvis approached Jackson, Michigan officials to support efforts to illuminate the city's downtown with electric arc lights. They formed Jackson Electric Light Works in 1888 and built a hydro plant project at the Trowbridge Dam on the Kalamazoo River in Allegan in 1889. Foote began consolidating his small power companies and formed Commonwealth Power Company.

In 1907, Foote and Jarvis built the Croton Hydro project on the Muskegon River, the first project in the world capable of transmitting 110,000 volts of electricity. In 1920, they offered preferred shares to the public to secure financing for expansion into other energy sectors. Over the following decades, the company built coal-fired, natural gas, nuclear, and electric facilities. In 1946, the company formed a strategic partnership with Panhandle Company to convert former natural gas fields to underground storage areas.

CMS Energy was formally established as a holding company in 1987, with Consumers Power (later rebranded Consumers Energy in 1997) as its principal subsidiary. The company became publicly traded on the New York Stock Exchange on October 23, 1987. In 2003, CMS Energy moved its headquarters to One Energy Plaza in Jackson, Michigan. The company has since invested billions in Michigan's energy infrastructure, including the Cross Winds Energy Park wind farm in Tuscola County, which opened in 2014.

CMS Energy has established comprehensive sustainability commitments centered on achieving carbon neutrality and supporting Michigan's clean energy transition. The company has set ambitious goals to eliminate coal-fired generation by 2025 and achieve net zero greenhouse gas emissions from its electric operations by 2040, with a broader goal of net zero emissions from its natural gas system by 2050.

The company's Clean Energy Plan includes a $15 billion investment through 2040 to transition Michigan to cleaner energy sources. CMS Energy has committed to powering 1 million electric vehicles in its service area by 2030 and has already developed significant renewable energy capacity, including the Cross Winds Energy Park wind farm and multiple solar installations across Michigan.

CMS Energy publishes an annual Sustainability Report detailing progress toward environmental, social, and governance goals. The company participates in the CDP climate disclosure program and has received recognition for its environmental leadership, including Michigan Green Leader awards for sustainability initiatives.

On environmental justice, CMS Energy has developed programs to ensure equitable access to clean energy benefits and has committed to workforce development initiatives in underserved communities.

CMS Energy operates under extensive regulatory oversight from the Michigan Public Service Commission, which reviews rate cases, infrastructure investments, and service quality standards. The company's rate increase requests have faced scrutiny from consumer advocacy groups and industrial customers concerned about energy affordability.

In 2024, CMS Energy faced regulatory questions regarding grid reliability following severe weather events that caused extended power outages in portions of Michigan. The Michigan Public Service Commission ordered the company to submit detailed reliability improvement plans and invest in grid hardening measures to prevent prolonged outages.

Environmental controversies have included debates over the company's natural gas infrastructure investments and timeline for phasing out fossil fuels. Some environmental groups have criticized CMS Energy for continuing to build natural gas pipelines while simultaneously pursuing renewable energy goals, arguing that new fossil fuel infrastructure could become stranded assets.

The company has also faced scrutiny over its coal plant closure timeline, with regulators and environmental advocates pressing for faster decommissioning of coal-fired generating facilities. CMS Energy has defended its phased approach as necessary to maintain grid reliability while managing the economic impacts on affected communities and employees.

Consumer advocacy groups have raised concerns about utility affordability, particularly regarding rate increases tied to infrastructure investments and clean energy transitions. The Michigan Attorney General's office has periodically reviewed CMS Energy's rate proposals and customer assistance programs to ensure they align with public interest requirements.
