Portion of Badger Coulee Transmission Line Project located in Dane County energized
MADISON, Wis. – The portion of the Badger Coulee Transmission Line Project connecting the Cardinal Substation in the Town of Middleton to the North Madison Substation in the Town of Vienna has been energized.
While this 20-mile segment is complete and now moving electricity, the portion of the project between the North Madison Substation and the Briggs Road Substation in the La Crosse area is still under construction.
This 180-mile, 345,000-volt transmission line was approved by the Public Service Commission of Wisconsin in April 2015 and is expected to be in service by late 2018. The project will help ensure reliable electricity for the region and provide access to lower-cost power and renewable energy.
“We appreciate the cooperation of area residents as we completed work on this portion of the project,” said American Transmission Co. Senior Local Relations Representative Lee Meyerhofer. “We will continue our commitment to keeping the public informed, constructing the line in a safe and efficient manner, and protecting the environment.”

American Transmission Co. issues 2017 10-Year Transmission System Assessment
Capital expenditure of $2.8 billion to $3.6 billion is lower than recent years
PEWAUKEE, Wis. – American Transmission Co.’s 10-year plan for electric grid improvements calls for a mix of new construction and continued asset maintenance to maintain the company’s top performance in operations.
“Our long-range planning efforts assure the reliability that our customers depend on,” said Ron Snead, vice president of system planning. “The expenditures in this year’s 10-Year Transmission System Assessment are reduced from recent years, reflecting the measures ATC has taken to improve electric reliability.”
Specifically, the plan calls for expenditures of $1.4 billion in asset maintenance, $0.48 billion in regional Multi-Value Projects, between $0.7 billion and $1 billion in network projects and between $0.3 billion and $0.8 billion in other capital expenditures.
Asset renewal has played a key role in operating performance. “We achieved top quartile or better reliability performance in 2016 for our transmission network,” said John McNamara, vice president of asset management. “Maintaining a reliable transmission system in a cost-effective manner is core to our business and supports our customers.”

ATC and ITC Midwest Help Boost Power Grid Resilience
Utilities are two of 28 to join equipment sharing program
To help restore electric service to communities after catastrophic emergencies or significant natural events, 28 utilities – including American Transmission Co. and ITC Midwest – have now committed to participate in the RESTORE program, which establishes a proactive approach to providing critical equipment for utilities that need additional resources during disaster recovery. The program establishes a binding agreement between participating utilities.
The national importance of a strategic transformer reserve has been highlighted by the Department of Energy’s Strategic Transformer Reserve Report to Congress earlier this year. Newly formed at the time of that DOE Report, the RESTORE program is now a fully functional collaborative effort that takes advantage of regional cooperation and is consistent with DOE’s recommendation supporting voluntary industry-based options to address the reserve.
RESTORE, or Regional Equipment Sharing for Transmission Outage Restoration, was founded in 2016 by Louisville Gas and Electric Co. and Kentucky Utilities Co., PPL Electric Utilities, Tennessee Valley Authority and Southern Company to identify and share spare transformers and other transmission equipment, which will then be available for purchase by other participants in the event of a major disaster within their service area.
“Utility cooperation and the ability to call on additional resources play a critical role during times of natural disasters and other emergencies that can impact our electric transmission system,” said John Lucas, chair of RESTORE’s operating committee and general manager of transmission policy and services at Southern Company.
“Launching the RESTORE program, coupled with existing industry programs and each utility’s internal resources, further strengthens total grid resiliency for the region and electricity customers,” said Mark Davis, executive vice president and chief operating officer for ATC.
Jon Jipping, chief operating officer for ITC Holdings Corp., including ITC Midwest, added, “Establishing these types of relationships and being able to call on more than 20 neighboring utilities at a moment’s notice will mean a more efficient response and expedited recovery when experiencing these types of emergencies.”
The program has now expanded to include 20 additional participating utilities: Ameren Missouri; Ameren Illinois; Ameren Transmission Co. of Illinois; Associated Electric Cooperative, Inc.; six Duke Energy utilities; Duquesne Light Co., East Kentucky Power Cooperative, Entergy Corp.; Florida Power and Light Co., ITC Transmission; METC; Santee Cooper and South Carolina Electric & Gas Co.
RESTORE is designed to enhance the resilience and reliability of the power grid and provide additional sources for utilities seeking critical equipment during disaster recovery and does not replace existing programs or agreements already in place. The RESTORE agreement is now in place among all participating utilities, except a few that must first obtain state approval to execute the agreement.

About HVDC technology
HVDC transmission was first commercialized in 1954, and since then, continuing advances in component and control technologies have reduced cost and increased flexibility leading to the successful implementation of approximately 200 HVDC projects on six continents. HVDC transmission typically consists of two converter stations connected by a long transmission line. One station converts AC to DC for power transmission, and the second converts DC back to AC for delivery to consumers. HVDC transmission lines can be installed overhead, underground or underwater using submarine cables.
The advantages of HVDC include:
- lower line losses,
- improved grid reliability and resiliency,
- power flow control and
- ability to connect asynchronous or out-of-phase systems.

Update: Transmission system restoration in southwest Wisconsin
June 29, 4:55 p.m.
MADISON, Wis. – Crews are continuing restoration work on two 69-kilovolt lines that were damaged during June 28 storms in southwest Wisconsin.
Restoration efforts are ongoing in the Village of Livingston and an area south of Cobb.
There is a transmission-related power outage in Livingston. Because distribution wires are attached to the poles that are down, restoration is taking longer than usual. The estimated return to service for Alliant Energy customers is Friday, June 30. There are no other transmission outages that are causing power outages for electric customers.
ATC expects to complete restoration work by Saturday.
We are committed to restoring power as soon as possible and working in a safe manner.
If you are in any of these areas, please stay away from downed lines and pay attention to road conditions and closures.
