All Liberty service areas are within the High Fire Threat District and have been designated either “Tier 2” (Elevated) or “Tier 3” (Extreme) fire risk, meaning that the possibility of wildfire is at an elevated risk. To combat this risk, Liberty developed and is currently executing an aggressive Wildfire Mitigation Plan.
Background
Vegetation management Wildfire Mitigation Plan
Components of the Wildfire Mitigation Plan
Infrastructure hardening Public Safety Power Shutoffs (PSPS) Situational awareness
Vegetation Management
12 Feet
Vegetation Management
Prune branches and vegetation back to a minimum of 12 feet from the high voltage power lines to ensure adequate clearance is maintained
We will notify the property owner prior to starting work via a doorhanger. Customers can submit a tree trimming request at 530-546-1787
Install covered conductors Infrastructure Hardening
Over the next several years, Liberty will:
Replace conventional fuses with limiting fuses Test and replace aging poles Enhance grid topology
In North Lake, Liberty is:

Did you know Alert WildFire cameras are stationed throughout the North Lake area?
Conducting pole and
inspections Installing two new weather stations Trimming at-risk trees and other invading vegetation Installing covered conductors in Meeks Bay

PSPS
Public Safety Power Shutoffs
A Public Safety Power Shutoff, or PSPS, is a safety procedure where Liberty proactively turns off power in certain areas when and where weather conditions create a high wildfire risk. Liberty will only implement a PSPS as a last resort to protect the safety of our customers and communities.
While no one factor will determine a PSPS, Liberty coordinates with fire weather experts to monitor:
Determining When to Issue a PSPS
Forecast sustained wind and gusts Low humidity levels Dry fuel conditions Red flag warnings
Determining When to Issue a PSPS
Energy Release Component (dry fuel conditions) exceeds 92nd percentile Wind gusts exceed 40 miles per hour Fosberg Fire Weather Index (measures speed of potential fire) exceeds 50 INITIATE PSPS PROTOCOLS
50 MPH
WIND GUSTS
TRANSMISSION LINES SUBSTATION DISTRIBUTION LINES 5 MPH
WIND GUSTS
Determining When to Issue a PSPS
The length of a PSPS will be determined on a case- by-case basis, but the power restoration process will follow a simple formula:
Fire conditions improve
Restoring Power After a PSPS
Liberty dispatches crews to conduct safety inspections of the grid Liberty makes any needed repairs Power is restored
Approximately 48 hours before power is shut off Approximately 24 hours before power is shut off Just before power is shut off During the PSPS Once power has safely been restored The multiple factors Liberty assesses before deciding to shut off power are
should prepare for a scenario where a PSPS might need to be instituted without 48 hours’ notice.
When and How Will I Be Notified?
Timing of Notifications (when possible):
Phone calls Emails Twitter News Texts Facebook Radio alerts And more!
IT IS IMPERATIVE THAT CUSTOMERS UPDATE THEIR CONTACT INFORMATION AND FOLLOW LIBERTY ON SOCIAL MEDIA TO RECEIVE TIMELY PSPS NOTIFICATIONS.
Customers should consider the following to make certain their homes, businesses and families are prepared:
Call 1-800-782-2506 to confirm your contact information is up to date
How Can I Prepare for a PSPS?
Create an emergency kit Keep your important documents in a fireproof place and create password-protected digital copies Plan for medical needs that may be impacted by a power shutoff
