ITC Midwest: Final commissioning activities at Huntley substation expected to be complete this spring

ITC Midwest LLC, in a March 8 update regarding its Minnesota-Iowa 345-kV Transmission Line Project, told the Minnesota Public Utilities Commission that final commissioning activities at the Huntley substation are expected to be complete this spring.

Commissioning at that substation remained at 95% complete through the end of February, with overall completion at 99%, the company said.

As noted in the filing, the commission in November 2014 granted ITC Midwest a route permit for the project and associated facilities in Jackson, Martin, and Faribault counties.

In February, both Segment 2 (Fox Lake-Rutland) and the associated facilities restoration activities remained under observation pending final acceptance, the company said.

Construction activities in February for Segment 4 of the project – Huntley to Iowa Border – focused predominately on foundation installation, which reached 100% completion; overall completion is now at 70% overall.

Segment 3 – Rutland-Huntley – construction work continued in February with foundation installations reaching 100% completion, the company added, noting that overall completion is at 65% for Segment 3.

According to ITC Holdings’ website, the project includes a 345-kV line between the Lakefield Junction substation east of Lakefield in Jackson County, and the proposed Huntley substation south of Winnebago in Faribault County in Minnesota, and connecting to substations in northern Iowa. The project also includes extensions and relocations of certain 161-kV facilities in Faribault County, the site noted.

The commission granted two approvals before construction of the project: a certificate of need and a route permit, according to the site. The route permit identified the route (referred to as “Modified Route A”) that the commission felt was most appropriate for the project based on the analysis completed by the Department of Commerce, Energy Environmental Review & Analysis in the environmental impact statement for the project, according to the site.
