A statewide Flex Alert calling for power conservation was issued Thursday afternoon due to a natural gas shortage triggered by extreme cold weather in the United States and Canada, according to Cal ISO.
The Flex Alert, usually associated with the heat of summer months, was issued amid cool conditions and rain across the region. But weather in other parts of North America caused the problem, according to the system operator.
