Sacramento – The Office of Energy Infrastructure Safety (Energy Safety) today released its evaluation and approval of Liberty Utilities’ 2025 Wildfire Mitigation Plan (WMP) Update.
Energy Safety determined that Liberty is making improvements to its risk model and methodology. Liberty has also implemented a new component within its vegetation management quality assurance/quality control program that supports risk reduction by providing statistically valid feedback to its vegetation management contractors.
Energy Safety also identified areas of Liberty’s WMP that can be improved. These include demonstrating effectiveness of “sensitive relay profiles” compared to traditional hardening; providing milestone timelines and criteria for inspection pilot programs including LiDAR, infrared, and drone inspections; and performing cost-benefit analyses for various hardening methods for Liberty’s Stateline Resiliency Project.
The last of the 2025 WMP Update decisions, for PacifiCorp, will be released in the coming weeks. The 2025 WMP Update decision for LS Power was approved on Feb. 18, Horizon West Transmission and Trans Bay Cable on Dec. 11, 2024, Pacific Gas and Electric on Nov. 19, Southern California Edison, San Diego Gas and Electric, and Bear Valley Electric Service on Oct. 31, Oct. 30, and Oct. 21, respectively.
