We’re preparing for a series of weather systems through the middle of next week. While we expect to see active weather through the weekend that is likely to cause outages, most concerning is a strong weather system early next week. The combination of heavy rains weighing down vegetation along with saturated soils and breezy winds could lead to outages across much of our service area.

We understand how difficult it is to be without power. Our teams are preparing to respond, and crews will remain in the field to assess damage and restore power as long as it is safe. If your power goes out, we’ll work around the clock to restore it as quickly and safely as possible.

Visit PSE’s Alerts and Advisories page for information on our response efforts: pse.com/alerts.


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.

Hydrogen pilots

Hydrogen pilot at PSE’s Georgetown Training Facility – April 2021

PSE conducted its first hydrogen pilot at its Georgetown Training Facility in Seattle, in April 2021.

As a part of this pilot, the testing team performed a series of tests using 5%, 10%, and 15% hydrogen/natural gas blends and compared the results with 100% natural gas. For each of these scenarios, the system was tested for leaks, air quality after combustion, gas quality, and impact on the appliances used.

The tests allow PSE to become familiar with hydrogen natural gas mixes, protocols for its safe use, collect quantitative and qualitative data to infer system response, and understand the operational, safety, and customer use challenges associated with its use.

Hydrogen pilot at PSE’s Tacoma Operating Base – Jan 2022

PSE has kicked off a second hydrogen pilot at its Tacoma Operating Base. As a part of this pilot, a 15% hydrogen and natural gas blend was injected into a test distribution system (not impacting PSE’s regular distribution) comprising of a Regulator Skid and a separate Polyethylene (PE) distribution system.

The Gas Standards and System Engineering teams selected components of interest to study how they’re impacted by a hydrogen and natural gas blend. The team will continue to monitor the test system over a course of time, adjusting pressure levels as needed and testing for leaks using specialized hydrogen detection tools. At the end of the test period, they will conduct an analysis of all the components to determine how they have aged after prolonged exposure to the hydrogen blend.
