Barnhart to Branch River Project is a 65-mile, 345-kV transmission line that originates at Barnhart and terminates at Branch River, Wis. It involves 51 miles of converted 345/138-kV double-circuit lines and 18 miles of 138-kV line. The project is needed to strengthen the ATC transmission system, increase operational flexibility in eastern Wisconsin, and remove operating restrictions on the Point Beach Nuclear Plant in Two Rivers, Wisconsin, and Kewaunee Nuclear Power Station in Carlton, Wisconsin. In October 2012, ATC annouced they are reconsidering the Barnhart project since Dominion recently announced plans to close Kewaunee. The plant closure is currently under review by the Midwest ISO. ATC estimates the total cost of the proposed project to be between $193m and $262m, depending on the route and substation sites ordered by the PSCW. If the project receives all necessary approvals, construction would begin in the fall of 2016, with a 2018 in-service date.
