Cost of building power transmission line growing

MADISON, Wis. (AP) — Rising material prices and legal expenses are expected to add nearly $50 million more to the cost of a power transmission line being built across southern Wisconsin.

American Transmission Co., ITC Midwest and Dairyland Power Cooperative are building the 345-kilovolt Cardinal-Hickory Creek transmission line that would run more than 100 miles from Dane County to Dubuque County in Iowa. The utilities have notified the Wisconsin Public Service Commission that the overall cost of the project is now expected to top more than half a billion dollars.
