The California Independent System Operator (ISO) has issued a statewide Flex Alert, a call for voluntary electricity conservation.
Due to high temperatures in the forecast, the power grid operator is predicting an increase in electricity demand to levels that could exceed energy supply.
Energy reduction during a Flex Alert can prevent further emergency measures, including rotating power outages. Between 4 p.m. and 9 p.m., the ISO is urging consumers to:
- Set air conditioning thermostats to 78 degrees or higher, 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 take steps to prepare for the Flex Alert by doing the following before 4 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.
