Circuit Upgrades Help Reduce PSPS Outages


SCE continues making significant progress hardening the grid in high fire risk areas to reduce the need for Public Safety Power Shutoffs (PSPS). In 2023, SCE hardened 23 circuits by installing wildfire mitigation equipment such as covered conductor (also known as coated electrical wire), weather stations (to monitor wind speed, humidity and temperature) and devices to segment or isolate portions of circuits to minimize the number of customers impacted during a PSPS event. As a result, customers on circuits frequently impacted by PSPS experienced approximately 70% less PSPS outage time based on weather conditions in 2021 and 2022.

In 2022, SCE hardened 54 additional circuits and made enhancements to 16 circuits that were already hardened. The completed work reduced PSPS outage time by 88% for customers who experienced a PSPS outage compared to 2020 and 2021. In addition to SCE’s significant strides in reducing the impact of PSPS through grid hardening work, relatively mild weather and associated fuel conditions in 2021 helped to further reduce the need for PSPS.

In 2021, the company hardened 72 circuits and the completed work reduced PSPS outage time by more than 70% for customers who experienced frequent PSPS outages during dangerous fire weather events between 2019 and January 2021.

To continue reducing PSPS outages, SCE plans to harden approximately 45 additional circuits this year. Overall, SCE has installed thousands of miles of covered conductor in high fire risk areas to continue to reduce the wildfire risk and need for PSPS1.

    Work Phases

    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 covered conductor 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 a 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 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 scheduled 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.

    Although grid hardening activities help reduce the need for PSPS, weather and fuel conditions in your community may still require the use of PSPS during dangerous fire weather conditions1.
