Company History

Michigan Gas Utilities (MGU) serves a territory that is rich in Michigan historical drama. The company is headquartered in Monroe County, which was settled by the French in 1784 and is the second-oldest settlement in Michigan. The first American flag raised in the area now comprising the state of Michigan was in Monroe.

MGU's roots date back to pre-Civil War days, when gas was manufactured from coal and was used for street lighting and for lighting in private homes and commercial businesses.

How We Grew

The company got its start on December 10, 1859, when I. R. Grosvenor, B. F. Fifield, J. R. Rauch, C. K. Green and E. A. Lansing incorporated the Monroe Gas Light Company. At the end of the first year, 662,000 cubic feet of gas had been manufactured and sold through approximately 4,500 feet of wooden gas main. This company is the oldest gas property in the group of many small gas companies which merged together over a period of almost 70 years.

Natural Gas Supports Expansion

The complete system conversion to natural gas in the early 1950's was the key to MGU's phenomenal growth during the next twenty years. Throughout the 1950's, MGU established itself as an integral part of the growing Southern Michigan Region.

A Subsidiary of Integrys Energy Group

Michigan Gas Utilities changed its name to Aquila Michigan on March 14, 2002. The MGU name was restored on April 1, 2006, when Aquila sold the company and it became a subsidiary of WPS Resources Corporation (now Integrys Energy Group).

The strength of MGU's gas supply and storage has enabled the company to provide reliable, affordable and stable service to its customers throughout the years.
