The California Independent System Operator (ISO) has issued a statewide Flex Alert, a call for voluntary electricity conservation for Wednesday due to high temperatures that are driving up energy demand and power supplies.
The flex alert will take place from 4 p.m. to 9 p.m. In this time frame, the power grid is most stressed because of high demand and less solar energy. Reducing energy use during a Flex Alert can help stabilize the power grid during a time of tight supply conditions, and prevent further emergency measures, including power outages, officials say.
“With above-normal temperatures in the forecast across much of the state tomorrow, the power grid operator is expecting an increase in electricity demand, primarily from air conditioning use, and is calling for voluntary conservation steps to help balance supply and demand,” California ISO said.
Tomorrow, before 4 p.m., Californians should:
- Pre-cool home by setting the thermostat to as low as 72 degrees
- Use major appliances, including:
- Washer and dryer
- Oven and stove for pre-cooking and preparing meals
- Adjust blinds and drapes to cover windows
Tomorrow, during the Flex Alert from 4 p.m. to 9 p.m, Californians should:
- Set the thermostat to 78 degrees or higher, if health permits
- Avoid using major appliances
- Turn off all unnecessary lights
