Puget Sound Energy transmission line project

Lake Hills-Phantom Lake 115 kV transmission line

Project completed

  • The new Lake Hills-Phantom Lake 115 kV transmission line was energized in 2021 and is now serving customers in Bellevue. We thank the Bellevue community for its patience during line construction.

Project overview

The electric system previously serving the Lake Hills neighborhood of Bellevue had limited reliability, increasing the possibility of outages for customers. PSE's Lake Hills and Phantom Lake substations were served radially, which means they were each served by one transmission line.

If the one transmission line serving a substation went out, the substation and the customers served by that substation lost power.

To help solve these problems, PSE built a new transmission line between the Lake Hills and Phantom Lake substations. The transmission line travels along NE 8th St and 148th Ave SE, ending at SE 16th St.

The new transmission line creates a "loop", which means the Lake Hills substation is connected to two transmission lines. If one line goes out, the other line will still feed the substation and provide power to customers. This project increases overall system reliability and allows for better use of existing facilities for customers.
