The Challenge

  • A single pipeline is the sole supply of natural gas to nearly 35,000 customers in the western Upper Peninsula, including the U.P.’s largest city, Marquette.

  • This pipeline runs from Texas all the way to Marquette.
  • A single failure in the line could result in long-lasting outages for tens of thousands of customers throughout the U.P.
  • The pipeline was originally installed in the mid-1960s and is at capacity, which is limiting economic growth in the U.P.

The Solution

The proposed Marquette Connector is a 42-mile pipeline connecting the Northern Natural Gas (NNG) Transmission pipeline currently serving the region to the Great Lakes Gas Transmission pipeline system, also transporting natural gas to the U.P.

The Benefits

Needed Reliability – A single pipeline is not sufficient to ensure consistent and reliable delivery of natural gas to the thousands of homes, businesses, and schools throughout Marquette and the western U.P. 

A single failure along the line could result in long-lasting outages impacting tens of thousands of customers throughout the region. And in the dead of winter in the U.P., this kind of event could be catastrophic.

Increased Tax Base – SEMCO’s investment in the area will increase the local tax base and ultimately help Marquette County to make greater investments in roads, schools, public safety and other local projects.

Economic Development – Local businesses, hospitals and universities require consistent, reliable energy, and that’s exactly what the Marquette Connector delivers. Energy supply stability means economic stability.

The Marquette Connector’s increased reliability and capacity will ensure that local businesses and economic development leaders have access to the energy they need to grow, thrive and hire.

The Details

  • The Marquette Connector will run approximately 42-miles and consist of two sections of pipeline.
    • 36 miles of 20” pipe originating near Arnold and running to near Eagle Mills.
    • 6.4 miles of 10” pipe running from near Eagle Mills into Marquette.
  • The pipeline capacity will be 144 Million Cubic Feet (MMCF) per day.
  • The current route for the Marquette Connector will run mostly adjacent to existing gas and electric transmission line right of ways.
  • The total cost of the project is estimated at approximately $135 - $140 million.
