Overview
CMS Energy Corporation is an American energy holding company headquartered in Jackson, Michigan. Its principal operating business is Consumers Energy, a regulated utility that supplies electricity and natural gas across Michigan. Consumers Energy serves more than six million people, representing a substantial share of the state’s population, through a system that combines power generation, transmission, electricity distribution, and gas distribution. CMS Energy’s other principal business is NorthStar Clean Energy, formerly CMS Enterprises, which develops and operates independent power-production and energy-related assets, with an increasing emphasis on cleaner generation and corporate energy customers. The company’s corporate history begins with the development of electric service in Jackson, Michigan, during the late nineteenth century. William Augustine Foote and Samuel Jarvis pursued municipal support for electric arc lighting in Jackson and subsequently established Jackson Electric Light Works in 1888. Their enterprises expanded through hydroelectric development and consolidation. A hydroelectric project at the Trowbridge Dam on the Kalamazoo River followed in 1889, and the Croton hydroelectric project on the Muskegon River, completed in 1907, became an important early high-voltage transmission milestone. The businesses associated with Foote and Jarvis eventually developed into Commonwealth Power Company and, through later corporate changes, the utility operations that became Consumers Energy. Over the twentieth century, the utility broadened its generation and fuel portfolio. It developed coal-fired, natural-gas, hydroelectric, and nuclear facilities and participated in underground natural-gas storage. Consumers Energy announced Michigan’s first nuclear power plant, Big Rock Point, in 1961. It also developed the Palisades Nuclear Generating Station on Lake Michigan, which began producing electricity in December 1971 and served approximately 400,000 people per day during its operating period. CMS Energy owned Palisades until 2006, when the facility was sold to Entergy. In the same period, the company pursued synthetic-gas technology, including a plant designed to convert liquid petroleum into pipeline-quality gas for Michigan customers. CMS Energy was created in 1987 as a holding company whose principal subsidiaries included Consumers Power and CMS Enterprises. The corporation became publicly owned and was listed on the New York Stock Exchange on October 23, 1987. Consumers Power adopted the Consumers Energy name in 1997, while the non-utility business later became NorthStar Clean Energy in 2022. CMS Energy moved its headquarters to One Energy Plaza in Jackson in 2003. The company has also pursued activities outside its core regulated utility operations, including independent power production, natural-gas transmission, energy technology, and an oil-exploration agreement in Eritrea announced in 2001. The company has invested in renewable generation and efficiency programs. Consumers Energy opened Cross Winds Energy Park in Tuscola County, Michigan, in 2014, a wind project with reported generating capacity of 105 megawatts. CMS Energy has also promoted habitat management, environmental education, and energy-efficiency programs. Its utility received Energy Star Partner of the Year recognition in 2014 and 2015. In 2021, CMS Energy completed the sale of EnerBank USA to Regions Bank, exiting that consumer-finance business. Today, CMS Energy remains primarily a Michigan-focused utility company, with Consumers Energy at the center of its operations and NorthStar Clean Energy representing its competitive and non-utility energy activities.
History
CMS Energy’s roots lie in the formation of electric utilities in Jackson, Michigan, during the late nineteenth century. William Augustine Foote and Samuel Jarvis sought support for illuminating downtown Jackson with electric arc lights and formed Jackson Electric Light Works in 1888. The enterprise built a hydroelectric facility at the Trowbridge Dam on the Kalamazoo River in 1889. After the initial projects proved viable, Foote consolidated several small power companies into Commonwealth Power Company. In 1907, Foote and Jarvis completed the Croton hydroelectric project on the Muskegon River. The project was notable for its ability to transmit electricity at 110,000 volts, an important development in long-distance power transmission. In 1920, the company offered preferred shares to the public to obtain capital for expansion into additional energy and generation activities. Over subsequent decades, the utility system grew to include coal, natural gas, hydroelectric, nuclear, and other facilities. The company expanded its natural-gas infrastructure in 1946 through a strategic arrangement with Panhandle Company to convert depleted gas fields into underground storage facilities. Nuclear power became another major part of the generation portfolio. Consumers Energy announced Big Rock Point, Michigan’s first nuclear power plant, in 1961. Palisades Nuclear Generating Station, located on Lake Michigan, began producing electricity in December 1971 and served a large customer base. CMS Energy retained ownership of Palisades until selling it to Entergy in 2006. The early 1970s also brought investment in gas-processing technology. CMS-related operations announced a reforming plant intended to provide heat for Michigan homes. The facility was described as the first in North America designed to convert impure liquid petroleum into pipeline-quality synthetic gas. CMS Energy was established in 1987 as a holding company with Consumers Power and CMS Enterprises as its principal subsidiaries. On October 23 of that year, it became a publicly owned company and was listed on the New York Stock Exchange. Consumers Power adopted the Consumers Energy name in 1997. During the late 1990s, the company was among the early utilities to introduce online billing services. CMS Energy diversified during the early twenty-first century. In 2001, it entered an agreement concerning oil exploration in Eritrea’s Dismin Block in the Red Sea. In 2002, it founded EnerBank USA. The corporate headquarters moved to One Energy Plaza in Jackson in 2003. In 2007, the company announced a planned $6 billion investment in Michigan’s energy future, aimed at modernizing generation technology and identifying additional energy sources. Renewable energy became more visible in the company’s portfolio during the 2010s. Consumers Energy opened Cross Winds Energy Park in Tuscola County in 2014. The project had reported total generating capacity of 105 megawatts and used wind-turbine equipment supplied under an agreement with General Electric. CMS Energy and Consumers Energy also participated in environmental stewardship, habitat programs, energy-efficiency initiatives, and community education. Consumers Energy received Energy Star Partner of the Year recognition in 2014 and 2015, while CMS Energy received industry recognition for shareholder returns and emergency restoration work. CMS Energy completed the sale of EnerBank USA to Regions Bank on October 1, 2021. On November 1, 2022, CMS Enterprises changed its name to NorthStar Clean Energy, signaling a stronger orientation toward clean-energy development and corporate customers. The group’s present identity is therefore centered on Consumers Energy’s regulated Michigan electricity and gas operations, supplemented by NorthStar Clean Energy’s independent power-production and energy-development activities.
