Flex Alert in Effect
Due to extreme heat forecasts for California and parts of the Southwest, the California Independent System Operator (CAISO) has issued a Flex Alert for Thursday, September 1, 2022, from 4 - 9pm. With temperatures expected to rise across the state throughout the holiday weekend, it is likely that the CAISO will continue to call for voluntary conservation efforts.
Energy Conservation
During a Flex Alert, consumers are asked to conserve energy to help the state balance high electricity demand and constrained power supply. Consumer conservation efforts can help reduce the likelihood that the state will need to initiate power outages to maintain system power.
What You Can Do to Help
We are asking residents and businesses to voluntarily conserve energy to help us lower demand. Consumers are urged to reduce energy use during the most critical time of the day between 4pm and 9pm when temperatures remain high and solar production is falling due to the sun setting.
Tips to conserve energy and stay cool while the Flex Alert is in effect between 4 - 9pm:
- Set air conditioning thermostats to 78 degrees or higher, if health permits.
- Use a fan instead of air conditioning.
- Close blinds and drapes.
- Defer use of major appliances, such as dishwashers and washing machines.
- Turn off unnecessary lights.
- Unplug unused electrical devices, including electric vehicles.
- Limit the time the refrigerator or freezer doors are open.
How to Prepare for a Flex Alert
Before 4pm, Californians should:
- Pre-cool home by setting the thermostat to as low as 72 degrees.
- Charge electric vehicles (EVs).
- Use major appliances, including:
- Washer and dryer
- Dishwasher
- Oven and stove for pre-cooking and preparing meals
- Adjust blinds and drapes to cover windows.
Tips to improve energy efficiency in your home & avoid bill surprises as the mercury rises:
- Unplug appliances and electronics: when not in use, devices like cell phone chargers, computers, TVs, and more, create a “phantom” load by drawing electricity when turned off but still plugged in.
- Change air filters regularly: a dirty air filter makes the A/C system work harder, which uses more energy.
- Upgrade your attic insulation: help keep the heat out and the cool air in.
