Central Ferry-Lower Monumental
​BPA will build a new 500-kilovolt (kV) transmission line from BPA's Central Ferry Substation, near the Port of Central Ferry in Garfield County, generally west through Garfield, Columbia, and Walla Walla counties to BPA's Lower Monumental Substation in Walla Walla County. The line will increase the electrical capacity of BPA's transmission system in response to requests for transmission service in this area.
 
As BPA prepares for construction, we continue to work with landowners, agencies and tribes regarding the project, easements and access road modifications. BPA anticipates that construction will start in the spring of 2014 and line energization is expected in December 2015.
