ATC uses drone to install bird diverters for the first time
We care about the environment, particularly in areas where our facilities are in close proximity to known avian flyways. That’s why this week, an ATC contractor will install over 450 bird diverters on the wires of three high-voltage electric transmission lines in three Wisconsin counties – Marinette, Ozaukee and Winnebago counties.
Using a fully autonomous LineFly™ robot connected to a heavy lifting drone, Canadian-based FulcrumAir will install the bird flight diverters to help keep birds safe while also ensuring the reliability of the electric grid.
“Bird flight diverters increase visibility of the wires and help protect birds from contacting the power lines while in flight,” said Michael Warwick, ATC senior environmental project manager and avian protection program specialist. “Most of the diverters will be installed over or adjacent to wetlands and bodies of water. These devices provide a visual deterrent to help protect larger, heavy-bodied species that do not maneuver easily – such as geese, swans, pelicans, cranes and other waterfowl.”
This is the first time ATC is using a drone to install bird flight diverters. In the past, ATC has installed bird diverters using a light-duty helicopter. Using a drone helps to increase safety and reduce installation costs.
The bird flight diverters will be installed in the following locations:
- Marinette County along a portion of a 138,000-volt line across the Peshtigo River near the Peshtigo River Train Bridge
- Ozaukee County along a portion of a 345,000-volt line within the Mequon Nature Center
- Winnebago County along a portion of a 138,000-volt line near South Asylum Bay along Bowen Street
Drone flight schedules may vary and are subject to change, based on weather. In the interest of safety, if you see the drone and robot in the area, please stay at least 300 feet away from the work area and refrain from stopping, viewing and photographing the work from a roadway.
Employees engage young learners at Woodland STEM Night
ATC employees recently participated in the Woodland Elementary STEM Night in Kingsford, Mich. About 300 kindergarten through fourth grade students and 500 parents attended the event. ATC was one of 16 local businesses to participate.
Models and materials table
ATC employees offered various models of transmission line structures, samples of conductor material, an insulator and a bird diverter for students to interact with and learn about. The kids loved looking at the different types of t-line structures including the lattice tower, steel monopole, wood H-frame and a Lego tower. We asked students if they knew what the structures were for, and many students knew that they were for electricity, and some even knew the difference between conductors and insulators. They were surprised at how big the conductors were!
Forestry activity table
The kids also participated in a fun, educational activity where they got to learn about tree anatomy. Our employees used wood cookies (cross sections of small trees two to three inches in diameter) with one side painted white and a small hole drilled for twine to tie a loop for the kids to hang their art. The students got to decorate the painted side as a snowman. On the unpainted side, the kids learned to age their snowman art by counting the tree rings. There were a handful of students that already knew how to age a tree, but most did not, and all enjoyed figuring out how old their snowman was. One student made it a challenge to find the oldest tree cookie snowman, which was 23 years old.
Additionally, we displayed a couple of cross sections from a larger oak tree that died from oak wilt in 2020. The tree was 70 years old. The cross sections displayed a timeline of major US history events that happened during that tree’s life, beginning in 1950.
While looking at the cross sections, one employee, who is a vegetation management specialist, had conversations with children and parents about what can be learned from trees such as atmospheric conditions from hundreds to thousands of years ago. Our employee explained that cross sections can also tell us when a tree is having difficulty growing due to conditions such as drought, flooding, fire and disease based on how large or small each annual growth ring was. The employee also described how trees move water and nutrients up and down the tree, as well as across the tree via medullary rays. We used these conversations with kids and parents to talk about the importance of having the right tree in the right place, and why ATC needs to manage vegetation on our rights-of-way for safety and electric reliability.
Essentially, the event was filled with electric transmission education disguised as fun activities – a great way for kids to learn about what we do at ATC!
Is it a conductor or an insulator?
As a presenting sponsor of the University of Wisconsin – Milwaukee Panthers women’s basketball with our Steals for STEM program, ATC engaged in a fun STEM activity with elementary and middle schoolers at UWM’s ‘School Day’ game at the university’s Klotsche Center on Friday, Jan. 20.
Before the game, ATC employees invited children to play the “Conductor or insulator?” spin-the-wheel game. Presented with options like “steel paper clip” or “glass bottle,” students pondered their answers carefully, smiled and cheered when they answered correctly. Our employees explained how electricity flows more readily within conductors than insulators and provided a few actual pieces of electric transmission conductors and insulators for the kids to pick up for a real hands-on experience.
The enthusiastic crowd of 1,500 students and teachers from nine different Milwaukee schools later cheered the Panthers on as they secured a 72-60 win against Robert Morris University’s Colonials.
ATC school visit stresses importance of cybersecurity
What type of activities are important to cyber security? You might be surprised at some of the well-informed answers an American Transmission Co. cybersecurity expert got when he asked the question in a fifth-grade classroom at Fairview School in Milwaukee. Students called out: Protecting their private information, logging into their accounts, with even one student mentioning using encryption!
During Wisconsin’s Computer Science Week in December 2022, ATC presented to Fairview’s fifth and eighth grade students about the importance of cybersecurity and its role in protecting ATC.
To illustrate how simple code works, our cyber expert introduced the students to the Caesar Cipher, a historic technique of shifting letters of the alphabet over by a certain number of letters to create a secret code that can only be deciphered if you know the key. First, he showed students coded phrases and asked them to read the phrases to him. Of course, they could not. He provided the cipher key and students quickly began raising their hands with the answers.
The cipher exercise provided a background to teach the students that finding a key is how hackers access information they should not. Our expert explained that to stop hackers from getting to information we want to protect, we need to make it difficult for them to find keys like our passwords.
Fairview students learned that one of the most important steps that we should take to improve our cybersecurity is to create strong passwords, known as passphrases. Our pro’s tips to the students were to create a memorable, unique sentence that is 20-30 characters long – the longer the better and never reusing them – for each online account. For example, the password “Mymoldyphonesmelledpurple” is 25 characters, it is memorable and unique. It is nonsensical, but that is okay, if it is something you can remember, does not exist anywhere else and does not contain commonly used passwords. It is a great start to a strong password.
Fairview students asked great questions about what makes a good password and one of the eighth graders even had our expert run a quick test on his personal password to see how safe it was – it turned out to be a good one, but it was a lesson for many Fairview students, and teachers, that there were opportunities to make their passwords even stronger.
We can all take this as a cybersecurity lesson and make our passwords as secure as possible to protect our online information.
ATC awards $65,000 to 18 recipients for planting projects
ATC has collectively awarded $65,000 to 18 recipients across its service area to plant trees and low-growing vegetation through its Community Planting and Pollinator Habitat programs. Now in its 10th year, ATC has given over 300 community awards for these projects totaling more than $625,000.
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 Habitat 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.
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.
Pollinator Habitat Program Recipients
“Part of the reason for the recent decline in pollinator populations is due to loss of habitat,” said ATC Environmental Project Manager Johanna Sievewright. “The Pollinator Habitat Program promotes vegetation that is both compatible with our vegetation management practices and it provides habitat for pollinators, which use the utility corridor as a flight path.”
The following entities received grants ranging from $2,500 to $5,000 to support pollinator habitat projects:
- Town of Ledgeview will plant native perennials in Ledgeview Park, east of the Winding Waters Way entrance to the East River Trail.
- Village of Bristol will remove invasive species and plant native forbs to create the pollinator habitat within the native oak savanna in the village’s new Bristol Bay Park.
Community Planting Program Recipients
“We recognize that trees and vegetation are among the features that make communities special places for residents and visitors,” said ATC Maintenance Program Manager Adam Helminiak. “While we can’t allow trees or tall‑growing vegetation in our rights‑of‑way, ATC’s Community Planting Program encourages and supports communities to plant trees and vegetation that will beautify communities in a way that doesn’t compromise the safety and reliability of the electric transmission system.”
The following entities received amounts ranging from $2,000 to $5,000 for planting projects on public property, outside the rights-of-way:
- Village of Bayside plans to add more trees throughout Ellsworth Park, the village’s main park, including around the tennis courts.
- City of Brillion will increase its tree diversity by planting new trees in its Horn Park, Heritage Park, Peters Park, along Main Street and in front of the city’s Historical Society.
- City of Greenfield will restore an urban forest along Honey Creek in the city’s Konkel Park.
- Village of Howard will plant a variety of native trees as part of the development of Howard Commons, the village’s first public square that will include a pavilion, amphitheater, biergarten, splash pads and an activity center surrounded by trails and a 92-acre village park.
- City of Iron Mountain will plant trees along Kennedy Road and along the exit to North Elementary School, as part of its “Safe Routes to School” focus.
- Kishwauketoe Nature Conservancy will restore two calcareous fens – rare and distinctive peat-accumulating wetlands—within the Conservancy.
- Town of Ledgeview will increase its tree diversity as it replaces ash trees lost to emerald ash borer in the town-owned Ledgeview Golf Course.
- Village of Little Chute will update the landscaping around the entrances to Legion Park with perennial flowering plants and ornamental grasses to reduce park maintenance
- Mequon Nature Preserve will plant roughly 3,000 native tree and shrub seedlings to reforest part of the Preserve adjacent to an ATC transmission line right-of-way.
- Ozaukee County Planning and Parks Department will plant a variety of native trees in its newly acquired 131-acre Clay Bluffs Cedar Gorge Nature Preserve to increase its tree diversity after losing ash trees to emerald ash borer.
- Village of Rock Springs will add a hardy mix of trees, shrubs and bushes to naturalize an area impacted by two historic 100-year floods, as well as reduce road noise at Happy Hour Park.
- City of Stanley will increase urban tree diversity by replacing trees lost to emerald ash borer and a 2021 tornado.
- Sheboygan County will plant about 20 mature trees along a heavily used, multi-use pathway that connects the city of Sheboygan and the village of Kohler along County Highway PP.
- City of Stevens Point will restore pollinator habitat, reduce storm water runoff, and reduce facility net energy usage at the Stevens Point Transit facility. Using native forbs and grasses, as well as installation of select native trees will help achieve all three goals- while simultaneously beautifying a municipal property.
- Madison’s Urban Tree Alliance will place bare root trees in its gravel bed drip irrigation system to encourage root system growth and increase the likelihood of tree survival. The trees will then be planted at seven Madison Metropolitan School District locations to increase urban tree diversity after losing ash trees to emerald ash borer.
- Village of Waunakee will place bare root trees in its gravel bed drip irrigation system to encourage root system growth and increase the likelihood of tree survival. The trees will then be planted in four parks to increase the village’s tree diversity after losing ash trees to emerald ash borer.
- City of Waupaca will plant trees around the new ADA-accessible playground and splash pad at Swan Park to increase urban tree diversity and replace trees lost during park improvements.
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 adjacent to and within transmission line rights-of-way. ATC accepts applications for both programs from June 1 through Sept. 30.
