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.
BPA completed environmental review and preliminary engineering design in early 2011. The agency issued a record of decision to build the line in March 2011
. After approximately 2 years of project delays, BPA is moving forward with project construction. Construction is anticipated to begin in May 2014 and line energization is expected in December 2015. BPA held two "Meet the Builder" open-house meetings where attendees learned about the construction schedule, spoke with the contractor hired to build the new line and met the BPA project team.
