PROJECT STATUS

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.

Winter 2015

The Final Environmental Impact Statement (EIS) has been issued - published January 22, 2015.

The Denny Substation Project Final Environmental Impact Statement (EIS) has now been issued. The Final EIS responds to written and verbal comments received following the March 27, 2014 issuance of the Draft EIS. It also provides an evaluation of the anticipated environmental impacts of the project alternatives. For more information about the environmental review process, visit the SEPA Review page.

What else has 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. View the renderings of the preferred alternative.

  • We continue to refine the Distribution Network System design and its route through the Cascade, South Lake Union, and Denny Triangle neighborhoods. View the network system maps.

  • 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. Another new addition is a mobile coffee truck stationed on John Street at the site's perimeter. More events are planned for this winter and spring.
