As a provider of an essential service, we are working to ensure we are here for our customers, our community and our employees as coronavirus impacts the region.

With Governor Inslee’s phased reopening of select aspects of our community and economy, such as the construction sector, PSE is gradually returning maintenance and construction crews back into the field. PSE’s highest priority is the health and safety of our employees and communities. As such, we continue to adhere to current CDC guidance regarding COVID-19 while working in our community.

We are requiring our employees to maintain social distancing while working in the field. We encourage our customers to do the same when engaging with our employees.
