Northern Lights Expansion

About the project

The Northern Lights 2019 Project is composed of two discrete projects, the Northern Lights 2019 Expansion component and the Rochester Expansion component; the two projects will be built at the same time and Northern will be combining the two projects for the Federal Energy Regulatory Commission’s pre-filing process into a single application with FERC.

The proposed facilities, which are subject to change as the pre-filing process progresses, initially include, for the Rochester project: (1) construction of 12.3 miles of 16-inch-diameter greenfield branch line; (2) an increase in the maximum allowable operating pressure (MAOP) of an 8-mile segment of the La Crosse branch line; and (3) a new Rochester town border station (TBS).

The Northern Lights 2019 segment of the project will consist of construction of: (1) 9.9 miles of 24-inch-diameter greenfield pipeline, (2) 8.9 miles of branch line and mainline loops/extensions ranging in size from 6-inch- to 36-inch-diameter pipeline; (3) additional compression at Northern’s existing Faribault and Owatonna compressor stations; and (4) a new compressor station located near Carver, Minnesota.

In January 2019, Northern Natural Gas Co. (Northern Natural) received a favorable Environmental Assessment from FERC, allowing its Northern Lights 2019 Expansion Project to move forward.
