Michigan Department of Environment, Great Lakes and Energy, U.S. Army Corp of Engineers issued permit; work will include shoreline and submarine soil borings
PEWAUKEE, Wis. — American Transmission Co. will begin soil boring testing the week of May 13 in preparation for the planned replacement of ATC’s 138,000-volt submarine electric cables crossing the Straits of Mackinac that were damaged last year when an anchor struck them. The soil borings will begin along the Upper and Lower Michigan shorelines, near the McGulpin and Point La Barbe Riser Stations, and will continue along the lakebed of the Straits through June. The Michigan Department of Environment, Great Lakes and Energy and U.S. Army Corp of Engineers in mid-March issued a permit authorizing the work.
“Our goal is to fully assess the soil where we anticipate the new cables will be located, while minimizing shoreline and lakebed disturbance,” said ATC Project Manager Dustin Johanek.
Following the soil boring work, ATC will apply for additional regulatory and environmental permits from the U.S. Army Corp of Engineers and Michigan’s EGLE by the end of 2019. Beginning in the second quarter of 2021, ATC plans to remove the existing submarine cables and replace them with cables containing solid dielectric insulation to re-establish the two, approximately 4-mile, 138-kv circuits in the Straits. The in-service date is anticipated to be December 2021. ATC continues to work with tribal nations, regulators and nearby landowners to gather input on the cable replacement project.
Note to editors: In its December 2018 Transmission Expansion Plan, the Midcontinent Independent System Operator recommended the replacement of ATC’s two electric circuits in the Straits as soon as practical to ensure the continued reliable service to the Upper Peninsula. More information about ATC’s Straits Cable Replacement Project can be found on the project page. Details regarding the April 2018 anchor strike to ATC’s cables and the subsequent restoration can be found here.
Line is part of an integrated electric system serving customers in the region
Madison, Wis. – American Transmission Co. recently energized the approximately 4.2-mile, 345,000-volt Riverside transmission line. Project work included building a new substation near the Alliant Energy West Riverside Energy Center and connecting a new double-circuit transmission line to an existing 345-kV transmission line in the Town of Beloit.
The line is needed to connect the expanded West Riverside Energy Center to the electric transmission grid. The West Riverside Energy Center will include a natural gas-fueled generating station with an integrated solar installation. The estimated cost of the transmission line project is $42 million.
“We’d like to thank members of the public and residents for their cooperation as we worked to construct the transmission line and substation,” said ATC Project Manager Mark Sanzenbacher. “Crews are expected to complete restoration activities in the area this spring.”

ANCHORAGE, Alaska – Four Railbelt utilities, Golden Valley Electric Association (“GVEA”), Anchorage Municipal Light and Power (“ML&P”), the City of Seward (“Seward”) and Homer Electric Association (“HEA”) have jointly submitted an application to the Regulatory Commission of Alaska (“RCA”) for a Certificate of Public Convenience and Necessity to form a transmission-only utility in Alaska’s Railbelt region. Today’s filing is the culmination of more than four years of voluntary work by the above parties working in close collaboration with Chugach Electric Association (“Chugach”) and Matanuska Electric Association (“MEA”). The work to date has included an evaluation of how the formation of an Alaska Railbelt Transmission company can provide overall benefits to consumers. The Railbelt utilities have worked closely with American Transmission Co., (ATC) a Wisconsin-based transmission-only utility formed through a similar effort in 2001 in the Midwest.
Today’s filing with the RCA establishes:
- the need to form a transmission-only utility;
- the interest of each utility participating in the formation;
- a tariff that describes how transmission services will be provided to each of the existing Railbelt
utilities and other users of the system, including the allocation of costs; and
- the ongoing responsibilities of the Railbelt’s utilities to operate, maintain and invest in the
The next step in the application process is a determination by the RCA that the application is complete, following which there is a 6-month review period prescribed for the Commission’s decision. The Railbelt utilities’ application can be found on the RCA website.
Anchorage Municipal Light & Power – ML&P provides electric utility service to commercial, university and medical customers in the downtown and midtown business districts as well as industrial loads in the Ship Creek and port areas. In addition, it serves residential customers in some of Anchorage’s oldest neighborhoods in its roughly 20-square-mile area. ML&P powers Joint
Base Elmendorf-Richardson and sells electricity to other Railbelt utilities. www.mlandp.com

MADISON, Wis. – Crews responded to a downed wire on East Broadway near the intersection of Edna Taylor Parkway in Madison today.
The downed wire caused the closure of both lanes of westbound traffic on East Broadway. One lane of traffic has been reopened. Repairs are expected to be completed this afternoon.
The incident occurred after an equipment failure, which caused the wire to drop on the road.
Updated 1:28 p.m.: Both westbound and eastbound lanes of traffic have been reopened.
Twenty-three communities to plant outside transmission line rights-of-way; four recipients will plant inside the right-of-way, benefitting pollinators
PEWAUKEE, Wis. – American Transmission Co. has awarded collectively $58,600 to 27 recipients across its service area to plant trees and low-growing vegetation through two programs – the Community Planting and Pollinator Planting programs. Now in its sixth year, ATC has given more than 200 community awards for these projects totaling nearly $360,000.
Vegetation funded through the Community Planting Program requires that communities plant trees outside of high-voltage transmission line rights-of-way. Low-growing, compatible vegetation funded through the Pollinator Planting Program allows entities to cultivate species within the rights-of-way that benefit pollinator food and habitat. Both programs help maintain electric reliability of the transmission system by keeping tall-growing vegetation outside the rights-of-way.
“As an electric utility, we’re uniquely positioned to support the declining pollinator population,” said Mark Davis, executive vice president and chief operating officer. “We established ATC’s pollinator planting initiative about two years ago, developing our own rights-of-way and substation landscaping – following construction. The Pollinator Planting Program extends that opportunity to qualified applicants within our service area because recipients can plant low-growing vegetation in the right-of-way to develop spaces for pollinators. Meanwhile we continue to provide funding to applicants who wish to plant and grow trees outside the right-of-way through our Community Planting Program.”
Recipients of both programs commit to comply with ATC’s maintenance standards for all current and future planting plans and urban forestry activities near high-voltage electric transmission lines. Mequon Nature Preserve, Baird Creek Preservation Foundation in the town of Eaton and the cities of Stevens Point and Muskego all received funding to support pollinator planting projects. The following Wisconsin communities received amounts ranging from $500 to $5,000 for planting projects on public property, outside the rights-of-way:
|Baraboo||Gays Mills||Ozaukee County||Sheboygan County|
|Bristol||Kishwauketoe Nature Conservancy||Portage||Waterford|
|Dane Co. Tree Board||Madison||Port Edwards||Waupaca|
|De Forest||Milton||Richland County||West Allis|
Both the Community Planting Program and Pollinator Planting Program are part of ATC’s Grow Smart® initiative, which advocates for and provides suggestions of low-growing, compatible vegetation that can be planted in transmission line rights-of-way. ATC will accept applications again for both programs from June 1 through Sept. 30, 2019.
