Wildfire mitigation plans
With wildfires becoming more frequent and intense throughout our region, protecting the communities we serve while providing safe, reliable power is our highest priority. We've taken a comprehensive approach to preventing wildfires and creating greater resilience against wildfire risks in the West.

California
In 2018 the California legislature adopted Senate Bill 901. Under SB 901, California has taken a comprehensive approach to mitigating and creating greater resilience against wildfire risks. A key element of SB 901 is in the new provisions of the California Public Utilities Code (PUC) Section 8386, which require electric utilities to develop annual wildfire mitigation plans (WMPs) to prevent, combat, and respond to wildfires within their service territories. Under PUC 8386(c), utilities must include in their WMPs statutorily prescribed content addressing a list of specific issues.
To implement this requirement of SB 901, the CPUC initiated a new rulemaking proceeding in October 2018, referred to as Rulemaking (R.) 18‐10‐007. In R. 18‐10‐007, the CPUC adopted a deadline of February 6, 2019, for utilities to file their initial WMPs and ordered utilities to use a uniform WMP template. PacifiCorp filed its 2020 California Wildfire Mitigation Plan on February 7, 2020.
The Wildfire Safety Division transitioned from the California Public Utilities Commission to the Office of Energy Infrastructure Safety (Energy Safety) on July 1, 2021; Energy Safety was established to ensure electrical utilities are taking effective actions to reduce utility-related wildfire risk.

Oregon
On August 25, 2020, the Oregon Public Utility Commission (OPUC) initiated an informal rulemaking process (Docket No. AR 638) to address electric utility risk-based wildfire protection plans. The rulemaking process incorporates the recommendations of the Governor's Council on Wildfire Response and the guidance issued in the Governor's Executive Order 20-04. The Pacific Power Oregon Wildfire Mitigation Plan specifically guides the mitigation strategies that will be deployed in Oregon, consistent with Oregon Administrative Rules. These efforts are designed to reduce the probability of utility related wildfires.

Utah
The plan identifies Heightened Fire-Risk Areas (HFRAs) where Rocky Mountain Power employs enhanced vegetation management practices, more frequent asset inspections with expedited corrections for select risk conditions, and extensive system strengthening measures. The system strengthening measures take a variety of forms, including the installation of non-combustion fuses, covered distribution lines, steel poles, fire-resistant pole wraps or coatings for wood poles, and, in certain cases, the full reconstruction of a given line.

Previous plans and reports
Washington
On November 21, 2023, Pacific Power, a division of PacifiCorp, submitted the Washington Wildfire Mitigation Plan in response to a data request and ongoing wildfire risk analysis. The plan outlines specific operational practices, such as increased field patrols, corrections, and vegetation management, in response to situational awareness. It also includes baseline risk analysis for informational purposes, acknowledging the potential designation of high consequence areas in Washington in the future, which would broaden the application of mitigation programs
Wyoming
Rocky Mountain Power’s wildfire mitigation efforts in Wyoming are centered on certain operating practices, informed by ongoing wildfire risk analysis. This plan describes targeted operational practices that can be deployed in response to situational awareness. Such programs include additional field patrols, corrections, and vegetation management. The plan identifies Heightened Fire Risk Areas (HFRA), which are areas identified by Rocky Mountain Power at a heightened risk of wildfire.
Previous plans and reports
Montana
In December 2025, PacifiCorp submitted its Montana Wildfire Mitigation Plan to the PacifiCorp Board of Directors for approval. This plan is required under Montana statute due to the company’s ownership of transmission and generation assets within the state.
The plan outlines PacifiCorp’s approach to addressing the increasing wildfire risk across the Western United States. It details the methodology used to assess baseline wildfire risk in Montana and notes that no Fire High Consequence Areas (FHCAs) have been identified within the state. In addition, the plan describes targeted inspection practices, vegetation management strategies, system hardening initiatives, and operational measures that may be implemented based on the company’s ongoing situational awareness activities.
A public comment period was held December 16–28, followed by a public open house on December 29 in Hardin, Montana. The Montana Wildfire Mitigation Plan received formal approval on December 31, 2025.
Strengthening our system
We’re building our system to be more resilient long term for all seasons and weather conditions.
Situational awareness
We collect and analyze real-time data from 600 weather stations to predict and watch for wildfire conditions, allowing us to respond faster to weather events.
Operational practices
Our operational practices are focused on ways to prevent wildfires, including:
- Enhanced safety settings
- Emergency de-energization
- Public Safety Power Shutoff
