Flex Alert – Fri, June 18

The California Independent System Operator (CAISO) has issued a Flex Alert for Friday, June 18 asking consumers and businesses to conserve energy between the hours of 5 p.m. to 10 p.m

A Flex Alert is a call for voluntary conserving of electricity when there is an anticipated high energy demand. When consumers reduce electricity use during a Flex Alert, it can prevent the need for power outages.

To prepare for a Flex Alert, consumers are urged to manage their energy use prior to 5 p.m. by using energy during the mid-day, when you are likely using energy supplies produced from renewable solar resources.  

Tips to Manage Energy Use Before 5 p.m.

  • Pre-cool your home or work space by lowering your thermostat
  • Use major appliances (dishwasher, washer and dryer)
  •  Close window coverings
  • Charge electronic devices and electric vehicles

Tips to Manage Energy Use After 5 p.m. until 10 p.m.

  • Set thermostats to 78 degrees or higher
  •  Avoid using major appliances
  •  Turn off unnecessary lights
