ATC helps ospreys take flight with nesting platforms

Nesting platforms provide a safe place to perch, and ospreys in central Wisconsin have a new place to do just that. American Transmission Co. recently donated two osprey platforms to The Feather Wildlife Rehabilitation & Education Center in New London, Wis.

“We are happy to partner with The Feather Wildlife Rehabilitation Center because we care, and because we are committed to environmental leadership in all aspects of our business,” said Michelle Stokes, ATC environmental manager. “These platforms protect the ospreys and promote continued recovery of the species. They also enhance the reliability of the electric transmission system by offering the birds a safe place to nest.”

The platforms are part of ATC’s avian protection program. ATC supports sustainable environmental policies and actions. During facility siting and design, ATC identifies areas of heavy avian use and evaluates measures to mitigate potential avian impacts. ATC also installs flight diverters and perch guards to prevent birds from becoming injured by transmission lines or structures.

Across ATC’s service area, we have installed more than 100 osprey nesting platforms on or adjacent to transmission structures. The platforms support successful breeding of this once-declining species.

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.

 

 

 

Update: Transmission system restoration and outages in southwest Wisconsin

June 29, 9:30 a.m.

MADISON, Wis. –   Approximately 70 transmission poles along three 69-kilovolt lines were knocked down during June 28 storms in southwest Wisconsin.

Significant cleanup and restoration efforts are ongoing in the Village of Livingston area and south of Cobb, with some road closures reported due to downed lines.

We are committed to restoring power as soon as possible and working in a safe manner. Restoration efforts are underway.

If you are in any of these areas, please stay away from downed lines and pay attention to road conditions and closures.

American Transmission Co. unveils groundbreaking new method for transmission line construction

Solo-Driver™ offers a faster, greener and more cost-effective option for foundation installation using vibratory technology

PEWAUKEE, Wis. – American Transmission Co. has developed a new method for installing transmission structure foundations that is faster, safer, more economical and  more environmentally friendly than traditional installation methods. Solo-Driver™ is ATC’s new, patent-pending method for installing foundations using a vibratory hammer. 

To date, the utility industry has largely relied on two methods for installing transmission structures when a concrete base is not needed: direct bury and traditional vibratory installation. With Solo-Driver, now there is a third choice. 

Solo-Driver is the first method of its kind to employ a single excavator equipped with a vibratory hammer for foundation installation. For this method, caisson foundations have been modified to include side tabs that the vibratory hammer grasps. Using the tabs, the hammer lifts the foundation from where it is pre-positioned horizontally on the ground, rotates it vertically into position, and vibrates it into the ground to the required depth. 

“This new method is a game changer in transmission line construction,” says ATC Executive Vice President and Chief Operating Officer Mark Davis. “Solo-Driver is just one part of ATC’s commitment to excellence in transmission planning, construction and innovation, and we are excited to announce this new technology and share it with our transmission partners.”

Solo-Driver provides significant cost savings over traditional installation methods due to reduced labor costs, reduced equipment costs and increased efficiency. It has been shown to cut costs by as much as half in optimal conditions. The chart below compares Solo-Driver to traditional methods.

MethodAverage installation timeInstallations per dayCrew size
Direct bury150 min/structure45
Traditional vibratory75 min/foundation85
Solo-Driver™30 min/foundation182-3

 

Solo-Driver is safer than other methods. Traditional vibratory and direct bury installation methods require crews to manually position the foundation using one or more cranes and guiding cables. With Solo-Driver, the excavator and vibratory hammer maneuver the caisson, and safety interlock jaws on the hammer prevent it from dropping the caisson during installation, even if power is temporarily lost.

Solo-Driver has fewer environmental and landowner impacts than other methods. It requires significantly less equipment, which means less weight, resulting in minimal ground disturbance. It is also much quieter compared to other methods and requires just half of the overhead clearance of traditional methods.

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.
