Downtown Portland Temporary Power Interruption in March

Here’s how you can prepare for these planned outages — part of an essential project to strengthen the energy grid.

As part of our Marquam substation project to modernize the downtown grid and improve your service, we’ll be bringing new underground cables online this spring. We need to do it in incremental steps to avoid overloading the system, so it will require brief, planned outages in the areas shown on the map below.

Dates and times

Your building will be without power briefly on only one of these dates.

  • Phase 1: Sun., March 10, starting at 4 a.m.
  • Phase 2: Sun., March 24, starting at 4 a.m.
  • Backup date if needed: Sat., April 13, starting at 4 a.m.

Why multiple dates?

We’ve scheduled two phases to minimize the impact to downtown. As an extra precaution, we have April 13 as a backup in case of severe weather or other circumstances outside of our control. We’ll let you know in advance if any of the dates change.

How long will these planned outages last?

We’re starting the outages at 4 a.m. on a weekend when traffic is light, most businesses are closed and residents are sleeping. You’ll be without power on just one day and only briefly — ideally less than one hour. But this is complicated work, so it’s possible it may take longer. That’s why we want to help you prepare.

Take steps now to prepare

  • We encourage everybody to always have an outage kit on hand with a flashlight, extra batteries and other essentials.
  • Plan ahead for any equipment requiring power, including medical equipment.
  • Business should take steps to minimize disruptions and protect equipment. This includes having backup plans for electronic door locks, cash registers and other essential equipment. Make sure all employees are aware power will be out temporarily.
  • If your building has standby generators or emergency lighting, check now to ensure the systems are working properly.
  • For fire and security alarm systems, make sure battery backup systems are working, and notify your alarm-monitoring company so they are aware of the temporary power interruptions.
  • Hotel and apartment managers will want to inform guests and residents in advance of these planned outages.
  • Elevators will not work while the power is off, unless your building has backup power. It’s a good idea for building managers to post signs near the elevators in advance of the event. Do not use the elevator just prior to the 4 a.m. shutdown time.
  • Food service facilities may want to minimize the delivery of perishables on or near these dates.
  • Keep refrigerators closed when the power is off — food will stay cold for up to four hours. A full freezer will protect food for about 24 to 48 hours.
  • There will be no need to contact PGE to report this outage since it’s a planned activity.
