Seattle City Light to replace power transformer at Shoreline Substation

Shoreline electrical substation

Beginning in early May, Seattle City Light plans to increase system reliability by replacing an old power transformer with a new one at the Shoreline Substation, which is located at N 163rd and Meridian. Customers nearby are being notified of the work.

• The work will be similar to the first new transformer installation that took place at the substation in 2014.
• Construction will begin with jackhammering in the center of the substation yard during daylight hours in order to prepare the site for building the new electrical equipment.
• From approximately mid-August, crews will begin the assembly of the new transformer on its pad.
• Once assembly is complete, a truck-mounted mobile generator and oil processing tanker will be used to process the new transformer’s oil. 

If customers have questions they can contact Patty Breidenbach, Electrical Service Representative,  or 206-684-4795. The upcoming construction work at Shoreline Substation is one of the many investments in infrastructure City Light carries out in order to maintain and improve electrical reliability in its service area.
