Denny Substation Project
Pay My Bill   


Construction of the distribution network (also known as the Denny Network) began in the fall of 2015, and Denny Substation construction began in mid-2016.

The contractor determines the ongoing construction schedule and coordinates with the Seattle Department of Transportation (SDOT) and other civil infrastructure and private development projects to reduce pedestrian and traffic impacts.
