CMS Energy (CMS) utility Consumers Energy is carrying out an upgrade on its Michigan natural gas network, replacing 149 miles of pipeline, it said in a statement on Wednesday.
The existing pipes serve about 1.8 million customers, are made from cast iron and steel, and are roughly 100 years old, it said. The company has about 6.8 million power and gas customers in the state overall.
"These upgrades are an investment in securing our system, serving our customers this year and for years to come," said LeeRoy Wells, Consumers Energy's president of natural gas delivery.
The company is also progressing its Four Cities Metro Pipeline in Oakland and Macomb counties, a job that will continue until the end of the decade.
