Construction [Denny Substation]

The Denny Substation is located in South Lake Union on Denny Way between Minor Avenue N and Stewart Street. Construction began in 2016 and is now in the final stages as we work to complete construction, testing & commissioning of operational and life safety systems, ensuring code compliance and documenting final inspections and acceptance to secure our occupancy permit allowing us to open the publicly accessible public benefits of the facility. The initial energization process began in mid-2018, and the substation is expected to fully operational in 2019.
