What’s Current

ATC, Diggers Hotline and local utilities team up to promote safe digging

American Transmission Co. employees are meeting with contractors, landscapers, plumbers, home builders, utility workers, farmers and other professional excavators throughout Wisconsin to discuss safe digging procedures when working around underground and overhead utilities.

The discussions are happening at Diggers Hotline’s Excavator Safety Meetings, which provide an overview of best practices and guidelines for excavating near a number of different types of facilities. The meetings run January through April. During the meetings, business owners, construction workers and municipal employees enjoy a meal while speakers explain the steps they must take before breaking ground on any project to avoid hitting underground gas, electric, fiber optic and private facilities, like underground sprinkler systems. Speakers also cover how to locate underground facilities and what to do in an emergency. Crews have the opportunity to network with the companies and organizations that own the facilities they may need to work around in the field.

Before digging, the first step is to call Diggers Hotline at 811 or to file a request online. Next, the crew should call the owner of the utility that they are working near. If workers are near ATC’s overhead or underground electric transmission lines, they should call (866) 899-3204 to discuss the facilities in the area and determine whether an ATC representative is needed onsite. This video provides an over view of best practices:

ATC participates in the meetings because we care about the safety of everyone that lives and works around ATC facilities. Check out the gallery to see photos from some of the meetings this year.


ATC receives approval from PSC for Riverside Transmission Line Project

Project will connect expanded West Riverside Energy Center to electric grid

Madison, Wis. – American Transmission Co. on Jan. 12 received approval from the Public Service Commission of Wisconsin to construct an approximately 4.2 mile, 345,000-volt Riverside Transmission Line Project. The project will consist of a double-circuit transmission line from a planned new substation near the Alliant Energy West Riverside Energy Center 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 ordered route is made up of segments from the two routes that ATC submitted to the PSC,” said ATC Project Manager Mark Sanzenbacher. “The anticipated project cost is approximately $42 million.”

The planned in-service date of the line is 2019. The PSC order and other documents associated with the proposed project are available at The docket number for this project is 137-CE-186.

Why responsible vegetation management is crucial for electric safety and reliability

At ATC, we care about delivering power safely and reliably. We also care about our environment and our communities. We work to balance our obligation to operate our facilities safely while being a respectful neighbor.

Removal of trees around transmission lines is an important part of operating the lines safely and reliably. If vegetation grows too close to the wires, it can cause a dangerous situation. A tree branch does not even need to come in contact with a transmission line to create a hazard; electricity can jump from the wires to another source, such as a tree, igniting a fire or creating a dangerous electrical path. If this happens, there is an obvious safety risk to anyone nearby or any crews working on the lines. Wide-spread power outages can also occur.

Understandably, some landowners question the need for removal of trees that might have been trimmed, or allowed to remain, in the past. After widespread outages in other parts of the country, vegetation management practices throughout the industry and at ATC have changed in recent years.

We manage vegetation within our rights-of-way, which include land directly below and beside the wires. In all cases, incompatible vegetation within the wire zone must be cleared. Tall-growing trees, vegetation and brush must be cleared, but some low-growing shrubs and plants may be permitted. In partnership with gardening expert and horticulturist Melinda Myers, our Grow Smart® program helps property owners and communities identify low-growing, beautiful, native vegetation that can be planted the smart way – a safe distance from transmission lines. View or print the Grow Smart Planting Guide or Grow Smart Pollinator Guide for suggested vegetation that is similar to what we plant in our rights-of-ways after construction.

We conduct right-of-way vegetation management approximately every five years with the goal of removing all incompatible vegetation. Interim work to trim or remove vegetation is sometimes needed. Crews use manual, mechanical and limited herbicide control methods to achieve a clear and safe right-of way. We contract with professional tree trimming and removal companies that have extensive experience in proper pruning and removal techniques.

We typically notify landowners by mail in advance of any work on their properties and provide a description of our plans, the reason for the work, the time frame and contact information for an ATC representative.

We are also proud to be recognized as a leader in responsible vegetation management practices. We have received the Arbor Day Foundation’s Tree Line USA® designation every year since 2008. Our Community Planting Program helps support efforts to beautify communities in our service area in a way that’s consistent with safety and maintenance standards. Eligible cities, villages, towns, counties and tribes may apply for financial support for planning projects on public property within their communities. Applications are accepted June 1 through Sept. 30 each year. In fact, we just awarded $56,000 to 27 communities as part of the project.

ATC awards $56,000 to 27 communities for planting projects

Community Planting Program recognizes communities for vegetation projects that help keep transmission lines safe and reliable

PEWAUKEE, Wis. – American Transmission Co. has awarded $56,000 collectively to 27 communities across its service area for the purpose of planting trees and other vegetation through its Community Planting Program. Vegetation funded through this program requires that communities plant trees outside of high-voltage transmission line rights-of-way, helping to keep the electric transmission lines safe and reliable.

“Now in its fifth year, the Community Planting Program has awarded nearly $300,000 to more than 175 communities for planting projects,” said Mark Davis, executive vice president and chief operating officer. “This is an initiative that we continue to be proud of because ATC is committed to helping sustain the environment that we all share. These communities also demonstrate their commitment to helping us keep the lights on by planting tall-growing vegetation a safe distance from transmission lines.”

In addition, recipients of the Community Planting Program 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. The following Wisconsin communities received amounts ranging from $500 to $5,000 for planting projects on public property. Villages of Friendship and Somers received funding to support pollinator planting projects, as part of ATC’s pollinator initiative:

The Community Planting Program is part of ATC’s Grow Smart program, 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 the Community Planting Program from June 1 through Sept. 30, 2018.
