The Bonneville Power Administration is replacing six existing underground transmission lines at Grand Coulee Dam with six new 500-kilovolt overhead transmission lines. Project construction is scheduled to begin in February 2012. The new lines will help ensure continued safe and reliable transmission of power between Grand Coulee Dam's third power plant and the BPA's vast high-voltage power grid.
