Puget Sound Energy substation project
Spring 2008 completion
- PSE completed the $4 million installation and construction of the new Sehome substation in Whatcom County
- The new substation came online on March 13, 2008
Puget Sound Energy demolished and rebuilt our Sehome substation, which serves customers in the Bellingham area. This was part of PSE's continuous effort to upgrade our electric systems to better meet our customers' current and future needs. The rebuilt substation is located just north of 721 N. State St. in the same location as the existing facility.
The project included demolishing the existing substation and rebuilding and upgrading the facility from the current 4 kilovolt (kV) system to a 12 kV system. This upgrade will give the area long-term capacity and reliability as well as help reduce future power outages.
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.
