A statewide Flex Alert, a request to voluntarily reduce power use by California’s power grid manager (ISO), will go into effect today due to extreme temperatures across much of California and a potential capacity shortfall on the state’s electric grid. The call for residents to voluntarily conserve power across California will be in effect today from 4-9 p.m. Residents are encouraged to pre-cool their homes, use major appliances, close window coverings, and charge devices or electric vehicles before the flex alert goes into effect.
California’s power grid operator called for a second day of voluntary energy conservation and the governor declared an emergency as much of the state sweltered under a heat wave that has baked the U.S. West. Palms Springs tied a record for the hottest day ever at 123, 29 Palms came in at 119. The California Independent System Operator has issued a Flex Alert for 6 to 9 p.m. today (Friday, June 18) to “reduce stress on the power grid due to extreme heat.” The alert was already in place from 5 to 10 p.m. yesterday. Gov. Newsom signed an emergency proclamation allowing power plants to ramp up operations if necessary to meet the demand for electricity.
The California ISO has issued a statewide FlexAlert for today (October 15), from 3 p.m. to 10 p.m. Rotating power outages are ordered in California when power demand reaches levels that strain the state’s electrical grid, and more are possible over the next few days. A statewide Flex Alert is one of the steps the operator of the state’s power grid can take to avoid unplanned power outages in extreme heat. A statewide Flex Alert is a request to voluntarily reduce power use by California’s power grid manager, the first of several steps that Cal ISO might take to avoid power interruptions in the nation’s most populous state.
The California Independent System Operator (ISO) issued a statewide flex alert from 3 to 10 p.m. today (Thursday October 1) due to expected high temperatures. A flex alert is issued when the power grid operator predicts an increase in electricity demand. Officials ask residents conserve energy, urging them to:
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.
The ISO says consumers can also take the steps below to prepare for the Flex Alert by doing the following before 3 p.m.:
“Pre-cool” their homes, or lower air conditioning thermostats.
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.
A statewide Flex Alert, a request to voluntarily reduce power use by California’s power grid manager (ISO), is the first of several steps that Cal ISO might take to avoid power interruptions in the nation’s most populous state. The call for residents to voluntarily conserve power across California will be in effect during the Labor Day weekend heatwave. Cal ISO issued a Flex Alert starting Saturday and continuing through Monday for the hours of 3 p.m. through 9 p.m.
