City Light Opens “World’s Coolest Substation”
This year, Seattle City Light opened its first new substation in over 30 years—Denny Substation—in the South Lake Union area. On Saturday, July 20, nearly 1,000 community members gathered at the site in the bustling Cascade neighborhood to celebrate Denny Substation and its public amenities with the community. Attendees enjoyed food trucks, music and ice cream while exploring some of the substation’s public benefits: art installations, an elevated walkway, a dog off-leash area and community spaces.

Dubbed “the world’s coolest substation” by Fast Company, Denny Substation is a unique example of innovative infrastructure built in the middle of an ever-evolving, dense and diverse neighborhood. City Light worked with the community to design the new substation to fit the neighborhood’s character, provide community amenities and serve as a model for environmental sustainability.

Energized in May 2018, Denny Substation is a long-term asset for City Light’s entire system and will provide reliability and flexibility to adjacent substations. The new substation was designed to last 50-100 years with the capacity to accommodate future needs in this neighborhood and beyond. Be sure to check it out the next time you’re in South Lake Union!

“Generators can be effective during a power outage, but they need to be used with care. Always use portable generators outside in well-ventilated areas and away from your home.”
