October Windstorm

We understand the stress and disruption that power outages can cause and we appreciate your patience as we work to restore power as quickly and safely as possible.

Crews have made excellent progress, and we expect the majority of customers to have power restored overnight. There will be some customers, mostly in Pierce and Thurston Counties, where it will take longer to restore power. Areas of focus in Thurston County include Boston Harbor, Pattison and Black Lake, downtown and southeast Lacey. In Pierce County, crews are patrolling lines serving Carbonado and Wilkeson, removing downed trees and restoring power. Crews are also working in the Rhodes Lake area, where damage is still considerable.

The outages that are likely to remain into tomorrow will affect smaller, more localized, groups of customers. These take time to repair as crews go from site to site to make repairs and restore power. Crews will continue to work around the clock until power is restored to all customers.

We are also watching the weather forecast and the potential for strong winds tonight in East King and Pierce counties. High winds could increase the number of outages or might delay current restoration efforts if conditions are not safe for our crews to continue to work for a period of time.

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.

Electric System Reliability

Providing safe, dependable, affordable and efficient electric service to your home is our highest priority. That's why we regularly inspect and test our electric system, making corrections before power-quality problems arise.

We monitor the reliability of our electric system on a daily basis and develop projects to improve electric service reliability for our customers.

Electric Reliability
  • Targeted reliability improvements
    • Tree wire
      Tree branch-related outages can be reduced by more than 95 percent when smaller diameter wire is replaced with tough, thick-coated wire designed to prevent outages when tree limbs fall into power lines. Tree wire cannot prevent outages caused by large falling trees.

    • Convert existing overhead lines to underground
      After a careful analysis of all specific criteria relating to the reliability issue, we may determine that undergrounding the distribution lines is the best and most prudent solution.

    • Reclosers
      By installing specialized equipment on power lines, the length and size of outages can be minimized. Reclosers sense a fault on a power line and automatically attempt to re-energize the line. If the recloser no longer senses the fault, it will reclose and re-energize the line without needing service personnel to deploy and physically patrol the line.

    • Supervisory Control and Data Acquisition
      Supervisory Control and Data Acquisition (SCADA) is an important aspect of managing the power system. SCADA is a system used for monitoring and controlling equipment remotely that enables faster restoration of power to our customers.
  • System-wide reliability improvements
    • Vegetation management
      Trees are beautiful and an important part of living in the Northwest, but they are a major cause of outages. To mitigate falling trees and limbs, we perform vegetation management on a cyclical schedule, with efforts focusing on achieving a safe and reliable electric system.

    • TreeWatch
      Certified arborists work with communities and property owners to identify and remove “at-risk” trees on private property to prevent tree-related outages.

    • Wildlife protection
      In an effort to avoid wildlife caused outages, special safety equipment is installed when maintenance activities occur to poles, transformers and high-voltage lines.

    • Underground cable replacement
      Some underground electric cable installed up until the 1980s has reached the end of its useful life. Replacing this failing cable greatly reduces localized outages and increases reliability.

    • Pole inspection and replacement
      Failure of utility poles can cause outages. To ensure the continued strength, safety and reliability of our utility poles, we regularly inspect wood poles and treat or replace them as needed.

    • Substation equipment replacement
      Specific types of equipment are proactively replaced in substations annually. These include transmission and distribution breakers, transformer protection devices and circuit switches to maintain system reliability.
