Welcome to the Denny Substation Project page, your portal to information about Seattle City Light's design, construction and associated elements of a new electrical substation, transmission line, and power distribution network necessary to serve areas of our growing city.

Fall 2014

Join us at a public open house on November 20th to get an update on the Denny Substation Project, and the substation's design.

Denny Substation Design Open House
Thursday, November 20
Cascade People's Center
309 Pontius Ave N
5 - 7 p.m.

What's been happening?
  • We've been working to complete the 90% design of the substation (Seattle City Light preferred alternative - SA3) and to refine potential public benefits. We'll be seeking approval of the 90% design and continued guidance of public benefits from the Seattle Design Commission. Renderings of the preferred alternative can be found here.

  • We continue to refine the Distribution Network System design and its route through the Cascade, South Lake Union, and Denny Triangle neighborhoods. Maps of the network system can be found here.

  • Work continues on the Final Environmental Impact Statement, which is scheduled for completion in early 2015.

  • The ALL RISE temporary arts program continues to be active, inviting the public to witness the temporary art displays occurring at the proposed Denny Substation site. Summer performances included dances, music and a light show. Also new is a mobile coffee truck stationed on John Street at the site's perimeter. More events are planned for this fall.
