Why PG&E Calls a PSPS Event

When extreme weather conditions are forecasted, PG&E considers proactively turning off power for safety, as such weather conditions increase the potential for damage and hazards to PG&E’s electric infrastructure, which could cause sparks if lines are energized. These conditions also increase the potential for rapid fire spread.

State officials classify more than half of PG&E’s 70,000-square-mile service area in Northern and Central California as having a high fire threat, given dry grasses and the high volume of dead and dying trees. The state’s high-risk areas have tripled in size over the last seven years.
