(P&GJ) — Consumers Energy has begun a summer construction program to replace 135 miles of century-old cast-iron and steel pipe across 15 Michigan communities, the utility said July 7.

The work is part of the company’s long-term Natural Gas Delivery Plan and involves more than 600 employees and contractors.

“These projects are a visible demonstration of Consumers Energy's commitment to delivering natural gas safely, affordably and reliably to our friends and neighbors who count on us,” said Holly Bowers, vice president of natural gas engineering and supply. “We focus on work that will have the most impact, ensuring that our natural gas system will be reliable for many more years.”

The company is also continuing work on the Four Cities Metro Pipeline, a major replacement project in Southeast Michigan, along with numerous smaller upgrades statewide.

Bowers urged motorists to expect intermittent lane closures and to use caution near job sites. The utility says the upgrades will keep average residential gas costs under $3 per day while supporting job growth over the next decade.

“We appreciate the patience of our customers as we carry out these upgrades in the coming months and continue to deliver natural gas reliably and affordably, regardless of what Mother Nature throws at us,” Bowers added.

Consumers Energy supplies natural gas and/or electricity to 6.8 million residents throughout Michigan’s Lower Peninsula.
