ITC Midwest on June 2 provided an update to Minnesota regulators regarding the company’s Minnesota-Iowa 345-kV Transmission Project and associated facilities in Jackson, Martin, and Faribault counties, noting that it is nearing the completion of stringing conductor for the Local-Huntley 69-kV transmission line and the NBEI-Huntley 161-kV transmission line.
The portion of the Local-Huntley line reconfigured as part of the project was built to 161-kV standards, but will be operated at 69 kV, the company said.
ITC Midwest said that on or after June 19, it intends to re-energize that transmission line and the associated portion of the 161-kV and 69-kV equipment at the Huntley substation.
Testing of the transmission lines will occur before the June 19 energization, the company said.
Construction, restoration, and revegetation activities continue along the associated facilities right of way and on the substation property, including construction of the 345-kV equipment at the Huntley substation, the company said.
As noted in the filing, the Minnesota Public Utilities Commission in November 2014 issued a route permit for the company to build the project. In April 2016, (for the Huntley substation), and October 2016 (for the 69-kV and 161-kV transmission lines), the commission found the plan and profile filings for the associated facilities in Faribault County were in compliance with the route permit, the company noted.
In a May 24 document mailed to a “landowner, resident, public official, or interested person,” the company noted that the project is needed to improve electric reliability, expand transmission capacity to support economic growth and investment, and to allow generating resources in the area – including wind generators – to efficiently transmit electricity to customers.
The company said that it anticipates that construction of a portion of “Segment 3” of the project, from Structure 299 to Structure 302, will be complete in late 2017. That portion is located in Section 18 of Verona Township, the company said, noting that all of Segment 3 is located in Martin and Faribault counties. Construction for that portion of Segment 3 of the project will involve replacing an existing 161-kV, single-circuit transmission line with a new 345-kV/161-kV, double-circuit transmission line, the company said.
The company also noted that it anticipates that the portion of the 161-kV circuit between the Rutland substation and the Huntley substation will be energized in early 2018. However, the company added, the 345-kV circuit will not be energized until all four segments of the project are completed.
