From a story on WKBT, La Crosse:
EAU CLAIRE, Wis. — The group advocating for a new series of high-voltage power lines has filed an application for a line that would cross the Mississippi River near Alma.
CapX2020, a partnership of 11 utility companies, filed a Certificate of Public Convenience and Necessity application with the Public Service Commission of Wisconsin (PSC).
The proposed Wisconsin section Hampton-Rochester-La Crosse power line would begin near Alma, cross the Mississippi River and run 40-55 miles until it connects with an 80-90 mile segment in Minnesota.
“The project will improve reliability in the La Crosse and surrounding rural areas as well as improve access to generation,” says Priti Patel, CapX2020 co-director. “It will also ensure that local communities and customers continue to enjoy reliable access to affordable electricity.”
The 345 kV line will be constructed with single-pole steel structures spaced approximately 800 to 1,000 feet apart. Project construction is expected to begin in 2013, and the line will be energized in 2015.

From an news release issued by Excel Energy:
MINNEAPOLIS – Phase One of a comprehensive study released today by a coalition of energy leaders, identifies future transmission needs in the Upper Midwest to support renewable energy development and to transport that energy to population and electricity load centers. Xcel Energy is co-sponsoring the study with Electric Transmission America – a joint venture between subsidiaries of American Electric Power and MidAmerican Energy Holdings Company, American Transmission Company, Exelon Corp., NorthWestern Energy and MidAmerican Energy Company.
The Strategic Midwest Area Transmission Study (SMARTransmission) sponsors retained Quanta Technology LLC to evaluate extra-high voltage transmission alternatives for new transmission development in the Upper Midwest. In phase one, Quanta evaluated eight transmission alternatives designed to support the integration of significant new wind generation within the study area, including North Dakota, South Dakota, Minnesota, Iowa, Wisconsin, Nebraska, Missouri, Illinois, Indiana, Michigan and Ohio. The plans would accommodate the integration of up to 56.8 gigawatts of wind generation. This translates into enough energy to power over 15 million households. If it is determined that less wind energy is needed, transmission recommendations would be adjusted accordingly.
The study’s Phase One results recommend three alternatives for further study based on a rigorous reliability assessment and stakeholder input. One of the alternatives is primarily 765-kilovolt extra-high voltage transmission, another includes 765 kilovolt combined with limited use of high-voltage direct current transmission lines, while the third constitutes a combination of both 345-kilovolt and 765-kilovolt transmission lines. The three alternatives will be evaluated further during the second phase of the study, scheduled for completion during the third quarter of 2010. The Phase One report can be downloaded at www.smartstudy.biz.

From an article by in the Wisconsin State Journal:
A Michigan utility company wants to build what it’s calling the Green Power Express, a super-sized transmission line that would link wind-power farms around the Midwest and carry their electricity to urban areas where the power is needed. . . .
The proposal would involve building massive 765-kilovolt transmission lines — nearly twice the capacity of the biggest lines now running through the state, at 345 kilovolts — and would run through parts of North Dakota, South Dakota, Minnesota, Iowa, Wisconsin, Illinois and Indiana.
A conceptual map has the line entering Wisconsin at the state’s border with Minnesota and Iowa, about halfway between La Crosse and Prairie du Chien, and heading east toward what appears to be the Madison area. An ITC official did not provide site details. . . .
Wisconsin regulatory officials, utility companies and environmentalists agree that more line capacity is needed to transport electricity generated by the growing number of wind farms. But they’re not sure ITC’s plan for giant-sized lines is the answer.
Michael Vickerman, executive director of the Madison environmental group, Renew Wisconsin, said he has “reservations” about the need for 765-kilovolt lines. Smaller transmission upgrades can accommodate new wind generation, he said.
Wisconsin Public Service Commission Chairman Eric Callisto also has questions.
“I don’t want to close any doors to what they have proposed but I have lots of grave concerns about the cost,” he said. ITC is proposing “very large lines” that would require “very large right-of-ways,” Callisto said. A right-of-way is the legal permission to use a property owner’s land or the area above it.
Callisto is part of a five-state panel — involving Wisconsin, Iowa, Minnesota North Dakota and South Dakota — discussing how to move electricity east from windier western states, and how to pay for that. The group has been looking into 345-kilovolt lines, Callisto said, and hopes to make recommendations this fall.
“We have to make sure that what we’re paying for benefits Wisconsin ratepayers,” he said.
In light of that effort, ITC may be a bit premature, a spokesman for Alliant said.
