Puget Sound Energy transmission line project
2019 project updates
The last major upgrade to the backbone of the Eastside’s electric grid was in the 1960s. Since then, our population has grown eight-fold and our economy depends on reliable power in ways that it did not 50 years ago.
The Energize Eastside project will build a new substation and upgrade approximately 16 miles of existing transmission lines from Redmond to Renton. Combined with continued aggressive electric conservation efforts, Energize Eastside will keep the lights on in our Eastside communities for years to come.
