ITC Holdings earlier this month said that ITC Midwest has completed the 345-kV Multi-Value Project (MVP) 4 transmission line, which the company said will relieve stress on lower-voltage lines that deliver power to electric customers, as well as facilitate the integration of renewable and cost-effective energy, such as wind energy, from southern Minnesota and northern Iowa for electric consumers across the region.
The company noted that ITC Midwest owns and operates 108 miles of the MVP 4 line, and that the last section to be completed – a 55-mile segment of MVP 4 – links ITC Midwest’s substation near Ledyard, Iowa, to the Colby substation located northwest of Mason City, Iowa. That line then extends 12 miles south to the Killdeer substation southwest of Mason City and 29 miles farther south to the area of the Hampton Tap, where ownership changes to MidAmerican Energy for 71 miles, ITC said. MVP 4 – which is one of 17 MVPs approved by the Midcontinent ISO (MISO) – then turns east in Franklin County, ITC said, adding that ITC Midwest owns the eastern 12-mile segment of the line, which ends at the company’s substation near Hazleton, Iowa.
To facilitate MVP 4, ITC Midwest built the new Colby and Killdeer substations, the company said.
As noted in the company’s statement, the 12-mile Black Hawk to Hazleton segment of MVP 4 was energized in November 2015; the 29-mile Killdeer to Hampton Tap segment was energized in August 2017; the 12-mile Colby to Killdeer segment was energized in September 2017; and the 55-mile Ledyard to Colby segment was energized this month.
ITC said that while MVP 4 is substantially complete, residents in the Ledyard to Colby area will still see crews working to remove construction materials, finish clean-up activities, and restore land affected by construction.
The company said that with MVP 3 put in service last September, the recent energization of MVP 7, and this month’s completion of MVP 4, about 230 miles of 345-kV transmission lines have been added to the ITC Midwest system.
ITC senior communications specialist Bob Doetsch on July 29 told TransmissionHub that the overall cost of the ITC segments of MVP is about $400m.
He noted that the ITC segment of MVP 7 was energized on June 30.
As noted in a Berkshire Hathaway Energy statement released earlier this month, that 79-mile, high-voltage regional transmission line linking southeastern Iowa and northeastern Missouri is now operational, including a 29-mile section that MidAmerican Energy built in three southeast Iowa counties.
Berkshire Hathaway Energy said that MVP 7 helps relieve congestion on other high-voltage transmission lines and provides a new pathway for wind energy generation in areas along the route, connecting substations in Ottumwa, Iowa, and Adair, Mo., which is east of Kirksville.
Berkshire Hathaway Energy said that MidAmerican Energy completed its section of MVP 7 on May 31, noting that the line runs through Appanoose, Davis, and Wapello counties.
The line was jointly built by MidAmerican Energy, ITC Midwest, and Ameren Transmission Company, the statement noted.
