Due to predicted high energy demand and tight supplies across the West, the California Independent System Operator (ISO) has issued a statewide Flex Alert, a call for voluntary electricity conservation, for Wednesday, July 28, from 4 to 9 p.m.
With higher than normal temperatures in the forecast for parts of interior Northern California, the power grid operator is predicting an increase in electricity demand, primarily from air conditioning use. The increase can make electricity supplies tight and cause strain on our power grid.
Consumers are urged to conserve electricity, especially during the late afternoon and early evening, when the grid is most stressed due to higher demand and solar energy production falling. Consumers are also asked to turn off unnecessary lights, delay using major appliances until after 9 p.m., and set air conditioner thermostats to 78 degrees or higher, if health permits.
The conservation measures can help stabilize the power grid during a time of tight demand and supply, and avoid power interruptions. Reduced electricity use during a Flex Alert can prevent further emergency measures, including rotating power outages.
Before a Flex Alert is in effect, consumers can take specific steps to manage their electricity usage to maintain comfort during days that conservation is needed. Specifically, consumers can:
- Pre-cool your home by lowering the thermostat
- Close window coverings to keep your home or apartment cool
- Charge electronic devices
- Charge electric vehicles
When the statewide Flex Alert is in effect, consumers can help by:
- Setting your thermostat to 78 degrees or higher, if health permits
- Avoiding the use of major appliances
- Turning off all unnecessary lights
- Using fans for cooling
