Project overview

To increase reliability for our customers on south Whidbey Island, Puget Sound Energy constructed a new 25 megavolt amperes (MVA) substation, upgraded a section of our existing 115 kilovolt (kV) transmission line, undergrounded a section of distribution line, and replaced aging poles on an existing transmission line (see project map).
