Puget Sound Energy substation project

Jenkins substation


Spring 2015 project updates

  • Construction is currently deferred until 2019, the project schedule is subject to change.

Project overview

PSE plans to build a new electric substation in Covington to increase electric reliability and capacity to customers in the Covington and nearby areas of unincorporated King County. The substation will also provide greater system flexibility, resulting in fewer outages. When complete, it will include one 25 megavolt ampere (MVA) transformer and have the space to add a second 25 MVA transformer, allowing PSE to double the capacity in the future without changing the substation footprint.

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.
