Seattle City Light plans to increase electrical reliability by installing a new transformer at the Shoreline Substation. Beginning in early May, City Light plans to increase system reliability by replacing an old power transformer with a new one at the Shoreline Substation. The work will be similar to a new transformer installation that took place there in 2014. See the map for the location of the Shoreline Substation: 
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.
The upcoming construction work at Shoreline Substation is one of the many projects City Light carries out in order to maintain and improve electrical reliability in its service areas.
