California ISO Issues Statewide Flex Alert Due to Extreme Heat

The California Independent System Operator Corporation (ISO) has issued a statewide Flex Alert, a call for voluntary electricity conservation, September 8-9 from 4 to 9 p.m. to reduce stress on the grid and avoid power outages. 

Consumers are urged to conserve electricity especially during the late afternoon and evening when air conditioners typically are at peak use. You can help avoid power outages by:

  • Turning off all unnecessary lights.
  • Using major appliances before 3 p.m. and after 10 p.m.
  • Setting air conditioners to 78 degrees or higher.
  • Closing blinds and drapes inside your home. 

The ISO has called on all available resources to be available to serve demand, however, conservation is needed to reduce the risk of further emergency measures, including rotating power outages. 

The ISO’s service territory serves about 80 percent of California’s electricity consumers.
