Atmospheric river event

We know how challenging and stressful it can be to lose power, especially when you are already dealing with the impacts of severe weather. We want you to know that we are doing everything we can to restore your service safely and quickly. The additional rainfall from this second major storm worsened the already saturated and unstable soil conditions in our region. Damage has been scattered throughout our service area with Kitsap, North King and Skagit counties being hit the hardest.

Our response teams and additional crews from outside our region are working around the clock as long as it is safe to do so. Above all, safety comes first — please take extra precautions and stay safe out there!

When is my power coming back on? 

We know that you need to make plans. To provide accurate restoration times, we need to assess the extent of the damage and what repairs need to be made. We start damage assessment as soon as it's safe for our teams to be in the field. We will set estimated restoration times once we have an initial assessment of damage.

alert 

Safety first. Never touch or go within 35 feet of downed power lines because they might be energized. Call PSE at 1-888-225-5773 or 911 to report problems.

Glacier demonstration project

Utility-side solutions for outage mitigation and balancing demand

In late 2015, PSE started construction on a 2-megawatt (MW), 4.4 megawatt-hour (MWh) lithium-ion battery system adjacent to the existing substation in the Whatcom County town of Glacier.

The project is funded in part by a $3.8 million Smart Grid grant from the Washington State Department of Commerce, in addition to a $7.4 million investment by PSE. The Glacier demonstration project is designed to perform three primary functions:

  • Reduce system load during periods of high demand
  • Balance energy supply and demand, helping to support greater integration
  • Serve as a short-term backup power source to “island” a portion of the local Glacier circuit during outages

Islanding: an evolving technology

Islanding (sometimes called a “microgrid”) is a complex process that involves many working parts. But, for battery installations like the one in Glacier, it basically means creating a power source that can safely operate separately from the grid.

Utilities across the country are testing battery technology and islanding capabilities with varying degrees of success. Each community must tackle distinctive geographical and weather challenges, different energy requirements, unique infrastructure, etc. In other words, while battery technology offers a lot of exciting potential, it’s still a process determining the best applications to serve customers’ unique needs.

As for PSE’s Glacier installation, the town’s remote location and energy infrastructure make it a good setting for testing and evaluating many applications, including islanding. The town is serviced by a 55 kV radial transmission line that runs approximately 10 miles along a heavily-forested highway, making it challenging for crews to locate and repair electrical problems during storms. Battery storage systems, like the one in Glacier, have the potential to provide several hours of back-up power to the town core during storm outages, as well as other grid-enhancing functions throughout the year.


Project details

The battery was energized in 2016, and in January, 2017, achieved its first successful islanding attempt. Between January, 2018 and June, 2018, Pacific Northwest National Laboratory (PNNL) performed two use test cases. Since then, PSE has continued to test the battery’s capabilities under planned outage scenarios – working toward the goal of successfully responding to unplanned outages.

As of August, 2019, PSE has successfully powered Glacier’s town core through more than six planned outages. It should be noted that planned outages and testing procedures can pose inconveniences for residents, but they ultimately yield vital information for responding to unplanned events.

The Glacier battery’s first successful unplanned response occurred on Monday, February 4, 2019. On that day, the battery remotely responded to an outage and provided power for approximately 4 hours, until repairs were made to the transmission line.

 

The glacier battery will serve as short-term back up power source to a core "island" of businesses and residences during outages.
