Managing the Threat of Significant Wind-Driven Wildfires

We will consider resorting to a Public Safety Power Shutoff when weather and fire experts forecast dangerous conditions, including strong winds, dry vegetation, and low humidity. Combined, these conditions create the risk that flying debris damage to wires and equipment could ignite a fire with the potential to spread rapidly and threaten communities.

We have a team of experts in grid operations, meteorology, and fire sciences that monitors weather models for any changes or shifts in weather patterns. The threat levels will be updated accordingly based on the latest guidance from the weather models.

Our decision to shut off power is based on actual conditions seen by our live field observers, weather models, and by other considerations including real-time weather data and early fire detection technology.

Our team of grid operations, meteorology, and fire sciences experts evaluates weather model forecast accuracy and prepares annual summary reports to help inform continuous improvement efforts around increasing situational awareness.
