Puget Sound Energy substation project


Easton substation project

Fall 2011 project completion
  • We started construction on the substation in July 2011 and completed construction in November 2011

Project overview

Puget Sound Energy upgraded our electric system to better serve our customers in Cle Elum and Easton by expanding the capacity of our Easton substation, located at 31 Pelton Avenue, Easton (see map). The work involved installing a new 20 megavolt ampere transformer to serve existing load in the area. Before the upgrade, the substation was operating above its design capacity. The new transformer more than quadruples the capacity of the old transformer, which was installed in the 1960s. All work was completed within PSE's existing property, with some work taking place outside the existing substation fence line.

What is a substation?

Substations are critical links in the electricity distribution system, containing utility circuit protection, voltage regulation, and equipment that steps down higher voltage to lower voltage. Before reaching homes and businesses, power is routed through our transmission system to a substation where it is changed to a lower voltage that can be utilized by customers.

Committed to keeping you informed

PSE will continue to provide updates to the community. We will notify residents and businesses near the project area when construction will occur. We aim to complete the work with as little disruption as possible.
