Circuits Selected for Expedited PSPS Enhancements

Circuits Selected for Expedited PSPS Enhancements

In 2021, SCE made significant progress expediting grid hardening work to reduce the need for Public Safety Power Shutoffs (PSPS) on circuits that experienced four or more PSPS de-energizations between 2019 and January 2021.

With work completed last year, the company estimates that customers on the most frequently impacted circuits experienced more than a 70% reduction in total PSPS outage time based on 2021 weather and fuel conditions.

To continue reducing these outages, SCE will harden more than 50 circuits this year. In addition, in response to the extreme weather experienced last November when wind gusts reached more than 80 mph in some locations, SCE will be making further enhancements to 11 of the hardened circuits last year.

SCE continues to implement our Wildfire Mitigation Plan to harden the grid in high-fire risk areas. Our goal is to make our communities more resilient to wildfires over time and reduce the need for PSPS. You will be notified when work may begin in your area.

Planning

During the planning phase, SCE looks at the best grid hardening options for reducing the minutes of service interruption experienced by customers. Most projects will involve the installation of insulated wire to be able to safely raise windspeed thresholds for PSPS events. Other upgrades might include the installation of devices that enable switching customers to other circuits, segmenting circuits, so fewer customers are affected during an outage, and adding weather stations to gain more localized weather information. There is also a thorough review of the latest ground conditions, such as recent burn scars, to assess the wildfire threat and the need for PSPS, or a combination of these measures.

Permitting

Once the scope of work is established, SCE can determine whether permitting is required. Most projects require at least one permit, typically from a city, county, or Caltrans, for road closures and crane permits. Additional permit requirements depend on the project's location. They may include state and federal land permits, environmental clearances, private property easements, Federal Aviation Administration approvals, or railroad rights-of-way permits. Permit approval may take as little as two months, or the process may be significantly longer.

Construction

Construction can begin once all the required permits are received and the work can be scheduled. In most cases, this work will require an outage; we will notify customers in advance if an outage is needed. Construction work may be rescheduled or delayed for a variety of reasons, including the need for crews to focus on emergency repairs, outage restrictions during heat storms, and the discovery of endangered species or historical artifacts on-site.
