What are we working on?

Construction continues on the Gardner Park-Central Wisconsin and Morgan-Werner West projects in north central Wisconsin. A new, temporary line between the Morgan and White Clay substations in Oconto and Shawano counties is nearly complete.

The temporary line is needed because the existing line is so critical to operations that it cannot be taken out of service to accommodate construction. Foundations are being poured and structures erected from the Weston and Kronenwetter areas near Wausau to the Whitcomb Substation in Shawano County.

We are putting the finishing touches on a substation in Fond du Lac County that will connect the Forward Energy Center to the transmission grid. Forward Energy Center is a 200-megawatt, 88-turbine wind farm expected to go on-line early next year.

Another new substation has been placed into service near Florence, Wis., replacing an aged and deteriorating facility located on an island in the Brule River. The new Aspen Substation is an integral component in our project to rebuild transmission lines between Conover, Wis., and Quinnesec, Mich.

We expect to file our construction application for the Rockdale to West Middleton project with the Public Service Commission of Wisconsin in mid-October. Check our website for updates.

A 69-kV transmission line that crosses the bog is scheduled to be rebuilt as part of our Cranberry-Conover-Plains project. The Public Service Commission of Wisconsin has ordered that we remove the portion of the line that crosses the bog because the large wetland complex has few other man-made features. The relocated line will be co-located with a county highway corridor


NERC president calls for more investment to ensure reliability


While the nation’s high voltage grid performed adequately this summer, North American Electric Reliability Corp. President Rick Sergel said the system is operating “at or near its physical limit more often than the past.”  In an appearance before the Federal Energy Regulatory Commission recently, Sergel called for “more investment in generation, transmission and demand-side measures…to ensure that our bulk power system remains reliable, adequate and secure.”  He noted that operators “did an excellent job managing the system” this summer, and while there were individual events, severe weather was more isolated than in the past, when prolonged heat waves across large portions of the country taxed the grid.

ATC became the first utility company to join Wisconsin’s Green Tier program in October 2005.  Administered by the Wisconsin Dept. of Natural Resources, Green Tier recognizes companies whose environmental practices go above and beyond what is required by state law. It is the first and only legislatively approved program in the country that seeks to improve environmental protection through performance-based oversight
