The Bonneville Power Administration energized and brought into service a new 500-kilovolt transmission line running between The Dalles and Goldendale.  The 28-mile, single-circuit line connects BPA’s Big Eddy Substation in The Dalles to the new Knight Substation northwest of Goldendale.  Big Eddy Knight was energized Friday afternoon.  The line increases the electrical capacity of BPA’s transmission system in response to requests for transmission service in this area.  Construction on Big Eddy-Knight began in the fall of 2011 and underwent design adjustments in the latter half of 2012 and 2013 to accommodate for newly discovered culturally sensitive sites along the route.  The project included the use of helicopters to string 20 transmission cables between two towers across the Columbia River near Wishram.
