PGE Projects

We're keeping power safe and dependable while building a grid that can serve a growing population, a changing climate and a strong local economy.

PGE works on strategic projects year-round to improve our system

We’re strengthening the electric grid to make it smarter, more flexible, efficient and reliable. That means replacing and upgrading aging equipment to boost resilience, reduce outages, support growth in our area and better integrate renewable energy.

Smaller, targeted projects occur within specific communities and corridors throughout our service area. They’re designed to address local needs — improving reliability, capacity and safety where it matters most.

In addition, we also support long-term growth across our region through large, multi-year infrastructure projects that connect with new power generation resources, address chokepoints and constraints in the system, and add capacity to strengthen the regional energy grid.

PGE projects in your area

Central service area

Prosper Portland

PGE is adding new electric service in support of Prosper Portland’s Broadway Corridor Redevelopment at the corner of NW 9th Avenue and NW Lovejoy Street. Anticipated project timeline: September 21 through November 18.

Goose Hollow Underground Project

We’re replacing aging distribution lines and substation equipment and placing portions of the system underground to help reduce local outages and strengthen the grid.

Harborton Reliability Project

This project will use advanced conductor technology to upgrade about a quarter mile of existing transmission line and build an additional quarter mile of line with two new poles within an existing transmission corridor, in utility right-of-way on the north edge of Forest Park. It will increase transmission capacity and enhance system safety and reliability.

Harrison Substation Project

Portland General Electric is upgrading a distribution line from the Harrison Substation. We’ll be replacing some power poles and upgrading wires to improve service and reliability for customers in Southeast Portland.

East service area

Springwater

We’re replacing 32 miles of aging transmission towers from south of Estacada through Gresham and into Southeast Portland. This work to improve safety and reliability will continue through 2030. Intermittent trail closures and detours of the Springwater Corridor Trail began at the south end in September 2026. Click project link for details of where and when closures are planned.

Summit-Summit 13 — Mt. Hood UG

We're protecting Mt. Hood, reducing wildfire risk, and improving service reliability near Government Camp by placing about seven miles of power lines underground. This work is happening during the summer months of 2026 and 2027, with roughly four miles completed by November of 2026. Work may result in temporary impacts on traffic and recreation while construction is underway. Additional information will be provided before the 2027 summer work begins.

South service area

Warm Springs Power Pathway

This project will upgrade an existing 99-mile transmission line to expand capacity and address critical transmission constraints. It will help deliver more electricity generated east of the Cascade Mountains to population centers such as Portland and Salem.

Monitor Substation

This major substation upgrade is part of the Marion County Grid Reinforcement Program, which will improve reliability and serve growing communities. It includes more than 20 distinct projects planned over the next 10 years.

West service area

Tonquin Project

We built a new substation and are upgrading 11 miles of transmission line to create a backup path for electricity. This improves resilience, strengthens reliability and supports continued growth in the area.

Westside Upgrade Project

We’re upgrading lines and poles along 15 miles of transmission corridor between Sherwood and Beaverton to relieve constraints, adapt to changing energy patterns and stabilize the system.

Horizon-Keeler #2 Line Coating

Robots will apply a heat protective coating to an existing 1.5-mile transmission line, allowing it to carry up to 20% more electricity and perform better in hot weather. Using new technology to improve existing equipment helps PGE meet growing demand without building new power lines.

Ongoing programs

We work year-round across the seven counties and 51 cities on key projects and programs that strengthen the reliability of the electric grid.

Wildfire safety and prevention

The safety of our customers and communities is one of PGE’s top priorities. We proactively and comprehensively work year-round across our service area to reduce the risk and impact of wildfires.

System hardening and equipment upgrades. We proactively maintain and upgrade our equipment to increase resilience, reduce outages and mitigate wildfire risk.
- Deliberate and targeted approach to converting overhead power lines to underground power lines in High Fire Risk Zones.
- Since 2019, we have installed almost 1,000 iron utility poles in specific areas to make our system more resilient against wildfire.
- Installing covered conductor, which is an insulated overhead power line designed to bolster power reliability and reduce wildfire risk.
Vegetation Management. Our service area includes more than 2.2 million trees and approximately 12,000 miles of overhead power lines. We conduct routine, year-round tree-trimming and vegetation management. In addition to routine tree-trimming, we also conduct enhanced vegetation management in High Fire Risk Zones.
Remote monitoring. We have a network of high-definition AI fire detection cameras that provide 24/7 visual observation of our High Fire Risk Zones as well as large portions of PGE’s service area. These systems alert PGE and public safety partners to potential wildfire ignitions and provide 360-degree fire detection triangulation capability, accurate to within 100 yards.
Weather monitoring. PGE’s meteorologists monitor weather conditions daily. Our network of weather stations provides detailed weather data, which supports making operational decisions, including when we should initiate a Public Safety Power Shutoff (PSPS). We share our weather station data publicly to improve regional forecasting and aid in the analysis of extreme weather events.
Smart Grid technology. We have protective devices in our High Fire Risk Zones that sense when there is a problem on the line (for example, if a branch or other debris contacts it) and automatically shuts off the electricity to prevent damage.
- These smart switch devices can also be controlled by grid operators to increase operational flexibility, reduce outage duration and minimize the number of customers experiencing a Public Safety Power Shutoff (PSPS).
- These devices generate additional benefits by improving reliability in all seasons for customers and providing additional situational awareness for PGE.
- Enhanced powerline safety settings.
Coordination. We work closely with local, state and federal agencies and Tribes to plan for wildfire and other emergencies. Collaborating with and maintaining strong relationships with these organizations helps us coordinate and plan for emergencies before they happen, so if an emergency happens, we are ready to work together.

Overhead and underground grid maintenance

To keep the grid safe and reliable, PGE regularly inspects equipment including poles, lines and underground services. Annually, PGE inspects about 10% of the electric grid. These inspections make sure that equipment is working properly, is safely in place and that any necessary work gets identified.

Vegetation management

Trees and power lines aren't a good combination. With safety as our top priority, PGE vegetation crews regularly prune trees to maintain necessary clearances.

Learn more about tree safety and maintenance.

Tree attachments

For everyone’s benefit, service lines attached to trees need to be detached and reconnected to utility poles. Learn more about tree attachments and how we’re improving safety and reliability throughout our service area.
