Description: CMS Energy was formed in Michigan in 1987 and is an energy company operating primarily in Michigan. It is the parent holding company of several subsidiaries, including Consumers and Enterprises. Consumers is a combination electric and gas utility company that provides electricity and/or natural gas to customers in all 68 counties of Michigan's Lower Peninsula. Enterprises, through its subsidiaries and equity investments, is engaged primarily in domestic independent power production. CMS Energy manages its businesses in three business segments: electric utility, gas utility and enterprises. Consumers operates the electric utility segment seasonally, because the consumption of electric energy typically increases in the summer months, primarily due to the use of air conditioners and other cooling equipment. Under the Consumers' gas utility segment, the company injects natural gas into storage during the summer months for use during the winter months when the demand for natural gas is higher. Peak demand occurs in the winter due to colder temperatures and the resulting use of heating fuels. Enterprises, through various subsidiaries and certain equity investments, is engaged primarily in domestic independent power production and the marketing of independent power production. More
