A Flex Alert calling for voluntary reductions in energy usage has been issued for today, September 8, from 4:00 p.m. to 9:00 p.m. Flex Alerts are issued by the California Independent System Operator (CAISO), an independent organization that oversees California's power grid, in response to above-normal temperatures and a greater demand for energy across the state than is available. 

During the Flex Alert period, conserving electricity and early evening is crucial because that is when the grid is most stressed due to higher demand and declining solar production. In the past, reducing energy use during a Flex Alert has helped operators keep the power grid stable during tight supply conditions and prevented further emergency measures, including rotating power outages. Learn a few tips on conserving energy below. 

Tips to Save Energy

• Set the thermostat to 78 degrees, health permitting. Turn it up to 85 degrees when not at home.
• Use a ceiling fan and raise your thermostat a few degrees. 
• Defer use of major appliances. Avoid using the oven or limit opening the refrigerator. The average refrigerator is opened 33 times per day. 
• Turn off unnecessary lights and unplug unused electrical devices. 
• Close blinds and drapes. 
• Charge cars after 10 p.m.
