The Denny Substation project draft environmental impact statement is available for review.  

This major electrical energy delivery project proposed by Seattle City Light is designed to serve South Lake Union and surrounding areas in Seattle for years to come.  The project includes a new electrical substation near Denny Way and Stewart Street, a transmission line from the new station south to an existing substation in the SODO neighborhood, and a network distribution system extending north of Denny Way.  

The draft environmental impact statement presents the results of environmental studies to date and comparisons of project alternatives. Public comments will be accepted from March 27 through April 26.  Seattle City Light will carefully consider and respond to all comments before preparing a final environmental impact statement to send to elected officials with project recommendations. Comments will be helpful in refining the report and ultimately in shaping the project.   

The project is part of the utility’s strategic plan and is needed to ensure high reliability and sufficient infrastructure to meet electrical service needs as growth continues throughout the South Lake Union, Cascade, Denny Triangle, Uptown, Belltown and First Hill areas. More information on the project, including its substation, distribution network, and transmission line, can be found at:
