Peoples Energy was the former name of a holding company whose main revenues came from its regulated gas utility subsidiaries, Peoples Gas (formerly Peoples Gas Light and Coke Company) and the North Shore Gas Company. In February 2007, the Peoples Energy Corporation merged with Green Bay, Wisconsin-based Wisconsin Public Service Corporation to form the Integrys Energy Group.
Established in 1849, in Chicago, Illinois, Peoples Gas today is the natural gas delivery supplier to approximately 830,000 residential, commercial and industrial customers in Chicago area. Peoples Gas currently has approximately 1,500 employees. Services provided to customers and maintenance of approximately 4,300 miles of natural gas main is the primary function of 850 field and support employees, represented by the Gas Workers Union, Local 18007.
Established in 1900, North Shore Gas today is the natural gas delivery supplier to approximately 158,000 residential, commercial, and industrial customers in 54 communities in the northeastern-suburban area of Chicago.
In February 2008, the Illinois Commerce Commission granted a controversial Peoples Gas/North Shore Gas request for a customer delivery rate increase. The approval, settled at $71 million, was expected to increase the average monthly customer gas bill by $7, or 4% to 5%. Peoples Gas/North Shore Gas, citing in part it had not filed for an increase in 12 years, initially sought a $102.5 million delivery rate increase in this proceeding.
Other Integrys subsidiaries include Peoples Energy Resources Company, LLC, Peoples Energy Services Corporation, Peoples Energy Production Company and Peoples District Energy Corporation, providing services in the oil and gas production, natural gas power generation, midstream services, and retail energy services industries. Integrys also owns and operates regulated and non-regulated energy businesses in Michigan, Minnesota and Wisconsin.
