Flex Alert Issued for October 15

October 14 – NEWS RELEASE FROM CALIFORNIA ISO:

 

Flex Alert issued for tomorrow; statewide energy conservation needed
Unseasonable high heat will lead to increased electricity demand late in day


FOLSOM, Calif. – The California Independent System Operator (ISO) has issued a statewide Flex Alert, a call for voluntary electricity conservation, from 3 p.m. to 10 p.m. tomorrow.

With high temperatures in the forecast, the power grid operator is predicting an increase in electricity demand, primarily from air conditioning use. The temperatures are above normal for this time of year, creating an anticipated shortage in energy supply in the late afternoon hours through the evening.

Consumers are urged to conserve electricity, especially during the late afternoon and early evening, when the grid is most stressed due to higher demand and solar energy production falling. Consumers are also asked to turn off unnecessary lights, delay using major appliances until after 10 p.m., and set air conditioning thermostats to 78 degrees or higher.

The conservation measures can help the power grid during a time of tight demand and supply, and avoid power interruptions. Energy reductions during a Flex Alert can prevent further emergency measures, including rotating power outages.

Conservation Tips:

  • Before 3 p.m., “pre-cool” buildings by setting air conditioning thermostats lower than usual; also, charge electronic devices and electric vehicles; and run dishwashers, washers and dryers and other major appliances.
  • After 3 p.m., set thermostat at 78° or higher.
  • Cool with fans and draw drapes.
  • Turn off unnecessary lights and defer use of appliances.
