A PSPS is a planned outage when fire risk is extreme:
- Hot, dry, windy weather
- Trees and branches can fall into power lines
That contact can create sparks, like striking a match
- In dry brush, those sparks can turn into a fast, out-of-control wildfire
- So SCE shuts the power off in high-risk areas until the dangerous weather passes.
No power → no sparks → less chance their equipment starts a fire.
