SDG&E Details Wildfire Prevention Protocols and Power Shutoffs
What happened
SDG&E has detailed its protocols for managing the electric grid to prevent wildfires, which can be triggered by dry and windy conditions in the region. When fire danger reaches extreme levels, the company may implement a Public Safety Power Shutoff (PSPS), which involves temporarily cutting power. These shutoffs are based on real-time monitoring of conditions such as wind speed, temperature, humidity, and vegetation moisture.
Why it matters
The company uses advanced tools, including weather stations, smart-grid technology, and artificial intelligence, to identify high-risk areas before a PSPS is enacted. Because the electric grid is interconnected, a power cut in one area may be necessary to protect the overall system from a serious wildfire threat.
The California Utilities Commission (CPUC) has been reviewing proposed powerline routes that involve SDG&E.
