CMS Energy Corporation

CMS Energy is a Michigan-based energy holding company formed in 1987 that operates primarily through Consumers Energy, its regulated electric and gas utility, and NorthStar Clean Energy, its non-utility power and marketing business. Consumers serves a broad customer mix across Michigan, including residential, commercial, and diversified industrial users, while NorthStar develops and operates renewable and other independent power assets. The company’s earnings are driven mainly by regulated utility operations, with NorthStar and energy marketing providing a smaller but strategically important non-utility earnings stream. CMS Energy’s business model depends on rate regulation, capital investment, and access to debt and equity markets to fund its large infrastructure program.
