Flex Alert in Effect 

Due to above-average heat forecasts for California, the California Independent System Operator (CAISO) has issued a Flex Alert for Wednesday, September 8th.

Read more in the recent CA ISO news release.

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

What You Can Do to Help

We are asking our 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 4 pm and 9 pm 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 p.m. and 9 p.m.:

  • 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 time the refrigerator door is open.
  • Prepare for a Flex Alert

Consumers can also take steps to prepare before the Flex Alert is in effect by doing the following:

  • “Pre-cool” homes to below normal levels in the morning or early afternoon.
  • 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 when the Flex Alert is not in effect.
