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 Centennial substation, located at 2334 SE 174th Ave. in Portland. The upgrade will increase system reliability, help prevent outages and meet the demands of growth in the surrounding area.
In addition to installing new equipment at the substation, we’re proposing to add additional fencing on the property to accommodate the equipment, and make the property safer and more secure. The new landscaping will follow City of Portland guidelines and enhance the appearance and safey of the area.
We’re working with the City of Portland to obtain the necessary regulatory review and approvals for this project. We hope to begin construction in March 2020.

Frequently Asked Questions
What changes is PGE making to the Centennial substation?
This is a complete upgrade of the existing substation. We’ll be working in stages so your power will not be interrupted. The proposed work will include:
- Removing the existing landscaping and equipment.
- Installing new, more resilient, more secure smart grid technology that can handle a larger load.
- Installing a second fence around the substation to increase security.
- Installing sensor lights for improved security.
- Installing new landscaping that will enhance the area and meet Portland’s tree guidelines.
What effect will there be on traffic?
We want to ensure your safety during this construction project, so temporary lane closures may be needed at times. Please follow any detours and signs placed to keep drivers, cyclists, pedestrians and workers safe. Allow extra time for commuting through this area or consider alternate routes.
What’s happening to the trees and other landscaping around the substation?
We will need to remove some trees and other landscaping in order to install the new equipment and expand the fence line. When construction is complete, we’ll plant new landscaping that will enhance the area and meet city tree standards. See simulation.
