The CapX2020 project is nearing La Crosse County and is scheduled to be completed in September, according to CapX2020 officials.
Currently, crews are working east of Galesville, installing towers and conductor cables as part of the 155 mile stretch of the project, beginning in Hampton, Minnesota and ending in Holmen.
Friday, crews demonstrated implosions, used to splice together conductor cables hanging from the towers.
"When we use the implosion concept, which is relatively new to the United States, it creates a better fit and overall good finished product," Brian Beste, the supervisor for transmission construction, said. "It's takes the human element out of the process and saves us a lot of time and man power."
So far, crews have executed 300 implosions on this particular section of the project and anticipate around 80 more implosions before the project is finished.
"Residents won't be hearing 80 individual implosions though, we do many of them simultaneously, so you really only hear one boom when numerous implosions are taking place."
However, once work begins in La Crosse County, residents will not have to worry about hearing the loud booms.
"The contractor we're working with on construction in La Crosse County isn't licensed to use the implosion process, so we'll be doing it mechanically, he said.
The entire CapX2020 project will span more than 800 miles and will cost nearly $2 billion. Xcel Energy said the upper midwest transmission grid has not been updated in more than 30 years and the demand for electricity in the region is rising.
