Winslow Tap transmission pole replacements


You may recall, PSE announced plans in 2019 to rebuild the aging Winslow Tap transmission line. The Winslow Tap line is the only line the serves the Winslow substation, which serves 3,500 customers in the south end. The transmission line was built in the 1960s and its equipment is nearing the end of useful life and needs to be replaced.

The fieldwork we conducted this summer revealed that some of the existing poles and equipment need to be replaced sooner than we had anticipated.

In late September, we began replacing specific poles and equipment to ensure continued safety and electric reliability. Crews have made significant progress and are on track to complete the work this fall. We appreciate the impacted community’s flexibility during construction, which allowed crews to prioritize completion of this work before storm season picks up.

Work continues on the design of the overall Winslow Tap rebuild project, which will replace aging infrastructure and improve safety and access so we can continue to serve customers reliably into the future.
