How could El Niño-magnified storm intensity affect Pacific Gas and Electric Company?
PG&E could face increased operational risk from severe storm events in Oakland The expected intensity of El Niño-related storms magnifies vulnerabilities in Oakland's infrastructure, leading to severe flash flooding. This flooding puts pressure on the city's aging stormwater drainage system, which is already stressed. For Pacific Gas and Electric Company, this increased frequency and intensity of severe weather events raises the risk of damage to utility infrastructure and operational disruptions within the city.

How it reaches Pacific Gas and Electric Company
-
Flash flooding near Lake Merritt caused the Oakland Zoo to close on October 8, 2026, due to El Niño-magnified storm intensity in Oakland. A city report indicates that much of the city’s stormwater drainage system consists of 85-year-old pipes and equipment that requires upgrades or replacement across miles of infrastructure. The city is currently considering Proposition 218, a property-related fee, to fund necessary repairs.

Why it matters
The city of Oakland is grappling with a multibillion-dollar problem related to its dilapidated stormwater drainage system, which consists of miles of 85-year-old pipes and equipment. If left unfixed, the city faces heightened risks of flooding and system failures, which are compounded by climate change and intense weather events.
Pacific Gas and Electric Company, like other utilities in the region, is exposed to the physical risks associated with these severe weather events. The increasing frequency and intensity of storms due to climate patterns mean that utility infrastructure is under greater strain, potentially leading to costly repairs and service interruptions.
