Harrison Substation Upgrades

Learn how we’re strengthening the energy grid and improving service for you.

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 improvement projects, we’re upgrading our Harrison substation and some nearby overhead and underground power lines this fall. We will also make some fencing and security improvements within the substation property.

Construction schedule

  • 7 a.m. to 5 p.m., Monday through Friday
  • September through December 2019

This schedule may change based on the needs of the project. While not anticipated, weekend and night work may be required at times.

What can you expect during this work?

  • Your home will continue to have service while we’re doing this work.
  • There is a bus stop close to where we will be working, so you may want to allow extra time to access the stop during construction.
  • Sidewalks will be closed intermittently.
  • In preparation for this work, we need to trim and remove some trees and other landscaping for safety.
  • Crews will cut into sidewalks and create trenches, install larger underground vaults and new conduit for the new underground lines. During non-work hours, we will cover these areas with steel plates for safety.
  • This is mostly underground work, but there is a small section where we will work on overhead lines.
  • We will work both inside and outside the substation fence.
  • This work involves digging with heavy equipment. At times, we will need to park some equipment on the street overnight.

Important traffic and safety tips

We’re taking steps to ensure your safety as we work in your neighborhood. Here’s how you can help:

  • Watch for temporary lane closures and detours. Allow extra time for commuting through these areas.
  • Watch for no-parking signs. To keep pedestrians and vehicles safe, we will reserve street parking spaces to accommodate equipment and create a safety buffer around our work area.
  • Follow directions from any flaggers, detours and signs used to keep drivers, cyclists, pedestrians and workers safe.
  • Please avoid all work areas and equipment, and make sure children know to never touch the equipment.

Building a brighter energy future for you

These upgrades will boost reliability to reduce the risk of outages, keep pace with growth in our region and improve overall system operations for all customers. This is just one of many projects we’re working on to enhance and modernize the energy grid, making it smarter and more resilient, and creating a platform for a clean energy future.

Thank you for your patience as we strengthen the energy grid.
