Puget Sound Energy electrical system upgrade

Berthusen substation

Winter 2009 project completed
  • Puget Sound Energy completed a $3.8 million electric system upgrade to improve reliability, increase capacity and help reduce the likelihood of future power outages in the Lynden area on Dec. 31, 2009
Project Overview

PSE upgraded our electric system in the Lynden area with our new Berthusen electric distribution substation, which improves reliability, increases capacity for the growing area, and helps reduce the likelihood of future power outages. Located at 2052 Main Street in Lynden, the new substation includes one 25 megavolt amperes (MVA) transformer with the space to add a second 25 MVA transformer as needed. This allows PSE to double the substation's capacity in the future without changing the substation footprint.

The $3.8 million project included clearing and grading the substation site, constructing the substation, connecting the substation to the transmission line, restoring the landscape, and installing roughly 1,000 feet of overhead and underground distribution feeders.

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.
