Holgate Substation Upgrade

As we work toward Oregon’s clean energy future, we’re strengthening the energy grid to make it smarter, more efficient and more reliable for you. Among our many projects, we’re planning to expand and upgrade our Holgate Substation, located at 4428 SE 24th Ave. in Portland. The upgrade will increase system reliability, help prevent outages and meet the demands of growth in the surrounding area.
