The power grid in California is coming under tremendous strain as western US states experience a record-breaking heatwave.
California faces another day of grid-straining extreme heat
Operators of California’s electricity grid acknowledged on Wednesday that a miscommunication led to a small number of power shutoffs during a period of great strain, even as the state faced another day of extreme heat that could prompt much larger rolling blackouts.
The miscommunication occurred on Tuesday afternoon between a Northern California utility and the California Independent System Operator as the grid was perilously close to running out of energy, said Elliot Mainzer, president and CEO of the CAISO.
Mainzer said he did not know specifically how the miscommunication occurred but he stressed the grid operator did not order rotating blackouts.
Mainzer said he did not know how many customers were affected when the errant power shutoffs occurred.
