Hillsboro Reliability Project

As we work toward Oregon’s smarter clean energy future, we’re strengthening the energy grid to make it smarter, more efficient and more reliable for you. Our efforts include an important five-year Hillsboro Reliability Project that will involve upgrading power lines and substations throughout the city. Here’s a quick overview of this critical project, which is set to launch this year.

Sustaining Hillsboro’s role as an economic engine for Oregon

Hillsboro is projected to grow significantly in the next 15 years, with new homes and businesses, as well as high-tech facilities. All of that growth means the city is going to use a lot more power. The Hillsboro Reliability Project will support this growth and ensure reliable service for years to come. It’s just one of many projects we’re working on across our service area to enhance and modernize the energy grid, making it smarter and more resilient, and creating a platform for a clean energy future.

Here’s where we’ll be working

There are eight unique projects that are part of this regional system improvement effort.

The proposed work will include:

  • Upgrading the Main Substation on Northeast 24th Avenue

  • Constructing two new transmission lines to the Main substation

  • Rebuilding the Orenco substation on Northwest Quatama Road

  • Upgrading the Sunset-Orenco transmission line

  • Constructing a new substation, called Evergreen, on Northeast Constable Street

  • Constructing two new transmission lines to the Evergreen Substation

Planning and permitting are underway

A project of this scale requires substantial coordination before we can begin construction. We’re working closely with the City of Hillsboro, Washington County, TriMet and Clean Water Services to make sure we address all permitting, land use, environmental, traffic and safety issues. We’re also giving advance notice to residents and businesses.

What you can expect during this project

This is a large, multi-phased construction project, and you’ll see our crews working in various parts of Hillsboro between 2019 and 2023. Here’s what you can anticipate:

  • We expect construction to being in September 2019 with the Sunset-Orenco transmission project and to continue through 2023.

  • We’ll be working in different areas during different periods. Each of the eight sub-projects (listed above), will have its own schedule and permits. Specific schedules will be announced as we move forward with the work. When construction is slated for your neighborhood, we’ll notify you in advance through mailers, social media, signage and outreach to neighborhood associations.

  • Crews will usually work between 7 a.m. and 5 p.m., Monday through Friday. While not anticipated, weekend and night hours may be needed at times.

  • Partial lane closures or detours may be required at times for the safety of drivers, bicyclists, pedestrians and workers.

We’re taking steps to ensure your safety. Here’s how you can help

  • Watch for temporary lane or street closures and detours. Allow for extra time for commuting through these areas.

  • Follow directions from any flaggers, detours and signs used to keep drivers, cyclists, pedestrians and workers safe.

  • Watch for “no parking” signs. To keep pedestrians and vehicles safe, we will reserve street parking to make room for equipment and create a safety buffer around our work area.

  • 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 are just some of the 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.
