American Transmission Company (ATC) on March 27 posted on its website its 2016 annual report, in which it noted that the $276m, 45-mile North Appleton to Morgan project is scheduled for completion in 2018.
The project includes 138-kV and 345-kV transmission line segments, new and expanded substations, installation of a large voltage control device, as well as improvements at 11 substations in northeastern Wisconsin and Upper Michigan, the company said. The new infrastructure will address emerging reliability concerns, generation changes, and changes in electric demand, ATC said.
The company also noted that foundations are being set and poles erected along the $580m, 180-mile, 345-kV Badger-Coulee transmission line from La Crosse to northern Dane County in western Wisconsin. Construction will continue throughout 2017 and 2018, the company said.
That line will enable the delivery of energy in support of reliability, economic, and public policy benefits across the Midwest as one of the Midcontinent ISO’s multi-value projects.
As TransmissionHub reported, ATC and Xcel Energy’s (NYSE:XEL) NSP-Wisconsin in 2013 jointly filed with the Public Service Commission of Wisconsin an application for a certificate of public convenience and necessity for the new line. NSP-Wisconsin’s half of the line will be shared with three co-owners, Dairyland Power Cooperative, WPPI Energy, and Southern Minnesota Municipal Power Agency-Wisconsin.
ATC noted in its report that the 58-mile Holmes-Old Mead Road Project – which improves reliability during maintenance and unplanned outages – has been placed in service on time and under budget between the Holmes substation in Menominee County and the Old Mead Road substation in Escanaba, Mich. The line addresses the unique needs of the electricity supply system in Michigan’s Upper Peninsula area, which is undergoing a change in generation mix, the company said.
ATC also noted that it received state regulatory approval for the 27-mile Spring Valley-North Lake Geneva Electric Reliability Project in the southern Wisconsin counties of Walworth and Kenosha. The area’s electric transmission system is vulnerable to low voltages and power outages, and will no longer adequately support the lower-voltage distribution system, ATC said.
The $71m project includes 69-kV and 138-kV lines, as well as a new substation, ATC said, adding, “We will begin construction in summer 2017, with an in-service date of 2019.”
Among other things, the company said that from starting operations in 2001 with $550m in assets, it is now a $4.4bn company, operating 9,540 miles of transmission lines, along with 548 substations. ATC said that capital expenditures were $463m in 2016, and capital expenditures are listed in the report as $493m in 2017; $451m in 2018; $368m in 2019; and $424m in 2020.
