Midway to Grandview Rebuild

The Bonneville Power Administration (BPA) decided to rebuild its 34-mile long Midway-Moxee transmission line and its 26-mile long Midway-Grandview transmission line. Both lines are 115-kilovolt (kV) wood-pole lines located in Benton and Yakima counties, Washington. The lines were built in the 1940s and are deteriorating due to age and need to be rebuilt to ensure reliable electric service. In addition, the Midway-Grandview line will be upgraded to increase the electrical capacity to allow local utilities to meet increased demand for power.  Construction will begin in September 2016 and will be completed in spring 2018.
