California ISO issues Flex Alert through Monday


SACRAMENTO, Calif. (BCN/KRON) – Officials with the California ISO have issued a statewide flex alert beginning on Saturday and extending through Monday, Sept. 7.

The ISO declared a Stage 2 emergency at 5:57 p.m. to prevent the power grid from entering Stage 3.

At 8:34 p.m. Cal ISO lifted the Stage 2 emergency, thanking everyone for their conservation.

The Flex Alert is in effect to urge consumers to conserve energy during this weekend’s statewide heat wave that is causing a rise in energy consumption.

The alert will be in effect between 3 p.m. and 9 p.m. all three days.

Temperatures during this heat wave are expected to peak Sunday, pushing demand for energy beyond levels of available supply.

Based on the current forecast and without significant conservation efforts, the ISO is planning for the potential for rotating power outages throughout the state between 5 p.m. and 9 p.m. Sunday.

Cal ISO says consumers can avoid using power between 3 pm and 10 pm by following these tips:

  • Set air conditioning thermostats to 78 degrees, if health permits.
  • Defer use of major appliances.
  • Turn off unnecessary lights.
  • Unplug unused electrical devices.
  • Close blinds and drapes.
  • Use fans when possible.
  • Limit time the refrigerator door is open.

Consumers can also prepare for the Flex Alert before 3 pm by following these tips:

  • “Pre-cool” their homes, or lower air conditioning thermostats to 72 degrees.
    • Charge electric vehicles.
    • Charge mobile devices and laptops.
    • Run dishwashers, washing machines and other major appliances.
    • Set pool pumps to run in the early morning or late at night.
