What’s Current

Happy National Pollinator Week!

American Transmission Co. is celebrating birds, butterflies and bees this week – June 19-25 is National Pollinator Week!

Helping pollinators is part of ATC’s GrowSmart® program, which helps property owners and communities identify low-growing, beautiful, compatible vegetation that can be planted the smart way – a safe distance from transmission line rights-of-way.

ATC also works with its construction contractors to plant seed mixes in our transmission line rights-of-way that generate beautiful vegetation beneficial to many species of pollinators.

One such right-of-way is at the Mequon Nature Preserve, where ATC provided funding for seed mixes beneficial to pollinators. Check out our gallery below from the June 13 planting event.

ATC has developed enhanced seed mixes to use in our rights-of-way that include plants that flower throughout the growing season. Longer flowering periods allow pollinators to benefit from nectar sources over a longer time span. Pollinators play an important role in contributing to our food security and healthy ecosystems by helping plants flower and reproduce.

If you’re interested in attracting pollinators to your own garden, check out ATC’s GrowSmart® Pollinator Guide that we created in partnership with horticulturist and gardening expert Melinda Myers.

ATC engineers develop groundbreaking Solo-Driver method for transmission line construction

American Transmission Co. is helping keep the lights on through a revolutionary approach to utility pole foundation installation. New transmission structures are springing up throughout ATC’s service area thanks to a new invention that is faster, more economical and more environmentally friendly than other methods.

ATC has a patent pending with the U.S. Patent and Trademark Office for its new Solo-Driver™ method.

Before Solo-Driver, ATC and the rest of the transmission industry relied on two popular foundation installation methods for utility poles when a concrete base is not needed – direct bury and traditional vibratory installation.

The direct bury method involves drilling a hole and placing a pole in it before backfilling the hole. This method requires roughly two and a half hours to install one foundation.

Traditional vibratory installation is a newer technique. It uses a vibratory hammer to drive the pole into the earth. This method typically requires one hour for setup and roughly 15 minutes to install the foundation.

ATC first used the traditional vibratory method in high volume to rebuild a 69-kilovolt transmission line between the Monroe County Substation near Sparta, Wis., and the Council Creek Substation near Tomah, Wis., in 2014. Next, ATC used the method to rebuild a 138-kV transmission line between Waukesha, Wis., Concord, Wis., and St. Lawrence, Wis.

Todd Maersch, consultant transmission line engineer, and Mark Sanzenbacher, senior project manager, were both involved with the 138-kV transmission line rebuild project. While they appreciated the environmental and timesaving benefits that accompanied the traditional vibratory installation method, they wanted a method that was more efficient.

“We watched the guys struggle with setting up the equipment every time,” said Maersch.


With traditional vibratory installation, a crew must wrangle the foundation into position using taglines. Taglines are removable ropes that attach to a foundation while it is suspended above ground by a crane. Crews use the taglines to align the foundation as it is lowered to the ground. Then, the crew must situate the vibratory hammer, which runs off a power pack, over the foundation to drive it into the ground.

“Every time the crew moved to the next foundation, they had to disassemble and reassemble everything. It would take an hour of setup to do five to 20 minutes of work,” said Sanzenbacher. “So our conclusion was that there had to be a better way to set this up.”

Driving Innovation

The two started brainstorming. They hoped that if they could eliminate the crane, they could significantly reduce setup times. They also wanted to power the vibratory hammer with excavator hydraulics instead of relying on the large power pack. They found a few techniques used in other industries, but nothing that would work specifically for transmission poles.

“I started reaching out to various companies that I found on the internet asking whether they’ve done anything where they’ve tried to install a transmission pole,” said Maersch. “Most of the answers were that they had tried to grab the actual pole, but were never able to make it work.”

“That’s when we started thinking that we could design a tab that’s integral in our transmission pole,” said Sanzenbacher.

The two found a vibratory hammer manufacturer who worked with them to retrofit poles with side tabs. The vibratory hammer would be able to lock on to the tabs and maneuver the caisson.

The whole process works like this:

1) Attached to an excavator, a vibratory hammer grips tabs affixed to a caisson. 2) The hammer lifts, rotates and drives the foundation into the ground. 3)Then, the hammer grasps a tab on the top of the caisson to drive the foundation to the required depth.

With the initial design complete, Maersch and Sanzenbacher were ready to test their invention. They tried five installations in five different soil types. It worked.

Driving Results

Today, Solo-Driver is the new normal for 69-kV and 138-kV foundation installation at ATC.

Solo-Driver requires just two to three crew members compared to five for traditional vibratory installation and direct bury. The method is very safe for the crew on site since there are no taglines, and no manual maneuvering of the foundation is required. Safety interlock jaws on the excavator prevent the foundation from being dropped during installation, even if the hammer loses power.

Since Solo-Driver requires just one excavator for installation, the weight of the equipment is much lighter than the equipment required for traditional installation methods, which reduces environmental impacts. The new method also requires reduced overhead clearance compared to other methods. This allows foundations to be installed in closer proximity to existing overhead lines.

Taken together, the lighter equipment and reduced overhead clearance required means Solo-Driver can be used in locations where direct bury and traditional vibratory installation methods are not options. For example, while traditional vibratory installation and direct bury methods are not typically viable options in wetlands, Solo-Driver is. Additionally, Solo-Driver does not produce any spoils, whereas the direct bury method can result in five to 50 yards of spoils per pole.

Field studies have shown that in optimal conditions, Solo-Driver could cut costs by as much as half compared to traditional installation methods due to reduced labor costs, reduced equipment costs and reduced project risk dollars due to a smaller construction window and expedited timeline.

Maersch and Sanzenbacher say they’re thrilled to see a more efficient method already at work in the field.

“We know that a lot of things in the utility industry are done because that’s the way they’ve always been done. We knew that there were probably some opportunities to improve our projects in terms of finding better ways to do things,” said Maersch. “It seemed like the right thing to do to find another way.”

ATC builds United Way Born Learning Trail for the community

Parents and children in Milwaukee’s Bay View neighborhood have a new trail to explore thanks to United Way and volunteers from American Transmission Co.

ATC’s asset planning and engineering team installed a Born Learning Trail at Lewis Playfield in Milwaukee’s Bay View neighborhood. The project provided a great opportunity for employees to give back to the community while working together and building team spirit. Team members used their talent, ingenuity and creativity to design and build the trail. They painted colorful games to compliment the engaging directions on the trail signage.

A United Way Born Learning Trail provides opportunities for parents of young children to learn and play together along a designated path in an outdoor setting. Signs guide the way through several fun activities that encourage children to interact and think about the world around them.

When ATC’s team was looking for a community volunteer project to do this summer, United Way of Greater Milwaukee & Waukesha County and Milwaukee Public Schools Department of Recreation and Community Services offered the perfect solution. ATC donated funding for a United Way Born Learning Trail, and Milwaukee Recreation offered an ideal location to install a trail just as our team was ready to go.

We care about our community, and we hope the United Way Born Learning Trail will provide countless opportunities for fun and learning!

ATC, Melinda Myers and Milwaukee County Zoo team up to help pollinators

Plants and flowers that help birds, butterflies and bees are growing strong at the Milwaukee County Zoo. That’s because kids and families worked with gardening expert and horticulturist Melinda Myers to plant pollinator-friendly vegetation at Party for the Planet in May.

The planting happened at the ATC Pollinator Garden, which was established on the zoo grounds in 2015.

Helping pollinators is part of ATC’s Grow Smart program, which helps property owners and communities identify low-growing, beautiful, compatible vegetation that can be planted the smart way – a safe distance from transmission line rights-of-way.

ATC works with its construction contractors to plant seed mixes in its rights-of-way that generate vegetation beneficial to many species of pollinators.

ATC continues funding through the Community Planting Program for planting projects

New this year, communities can apply for pollinator-specific projects

PEWAUKEE, Wis. – American Transmission Co. will begin accepting applications on June 1 for its Community Planting Program, which provides financial support to eligible cities, villages, towns, counties and tribes in ATC’s service area for planting projects on public property.

Now in its fifth year, the program helps communities where ATC transmission facilities exist. Since its inception, ATC has awarded nearly $240,000 to more than 150 eligible municipalities and counties.

To qualify, communities must commit that all current and future planting plans and urban forestry activities near high-voltage electric transmission lines will comply with ATC’s maintenance standards.

Recipients can use the program funding to plant trees and other tall-growing vegetation outside the transmission line rights-of-way. New to the program in 2017 is a pollinator-specific planting component. Funding also will be considered for communities who commit to planting low-growing, compatible vegetation such as those suggested on ATC’s Grow Smart pollinator guide. The pollinator-attracting vegetation can be a seed mix, plants, plugs or a combination thereof.

“Applying for funding through the Community Planting Program gives communities across our service area an opportunity to beautify their public space,” said ATC’s Chief Operating Office, Mark Davis. “It’s important to plant trees and tall-growing vegetation outside the right-of-way. Since we also know that pollinators are in decline due to loss of habitat, this program now offers a great opportunity to restore that habitat by planting low-growing species that attracts pollinators.”

ATC will accept applications through Sept. 30, and award recipients will be selected and notified by the end of the year. ATC will accept one application per community, and the awards range from $100 to $5,000.

The Community Planting Program is part of the Grow Smart initiative, which is directed toward individual landowners and advocates planting low-growing, compatible vegetation in transmission line rights-of-way. Additional information about ATC’s own pollinator planting initiatives, the Community Planting Program application and eligibility criteria are available on ATC’s Grow Smart website at
