In the past, infrastructure and utility facility aesthetics were often not a priority in design considerations. As cities become denser, utility structures are expected to be better integrated into their surroundings.

A substation like no other, the project will provide many neighborhood-friendly public amenities — including a dog park — when it opens next year.
