SACRAMENTO — Residents across California are experiencing rolling blackouts Friday as state officials and utilities work to meet energy demand during a heat wave, the California Independent System Operator said.
California ISO, which monitors the state’s electricity needs and power grid capabilities, issued a Stage 3 System Emergency because there is an electricity reserve deficiency.
“The ISO is unable to meet minimum contingency reserve requirements, and load interruption is imminent or in progress,” the agency said about a Stage 3 emergency.
The Stage 3 energy emergency is expected last until 11 p.m., according to PG&E.
Earlier in the day, Cal ISO issued a Stage 2 emergency and called a FlexAlert, asking residents to conserve energy.
