Flex Alert Declared

Due to the current hot weather, electricity conservation is necessary. As a result, state officials have called a Flex Alert.

What is a Flex Alert?

A Flex Alert is an urgent call for California businesses, governments and residents to voluntarily reduce their electricity use. The alert is used to prevent Stage 1 Electrical Emergencies - times when the demand for electricity is at its peak, typically during very hot weather.

How Does a Flex Alert Work?

  • The California ISO monitors and provides early warnings of possible electricity outages, which allow the public to better prepare for service interruptions and encourages energy conservation that may help prevent blackouts from occurring. Take a look at Today's Outlook.
  • When current system conditions and forecasted demand indicate immediate conservation is needed, the ISO issues a Flex Alert. See the Flex Alert Release (PDF) for Friday, September 8, 2011.
  • Businesses, governments and residents are notified through media and email to reduce use.
  • When possible, Alerts are regionally targeted to where the system is stressed.
  • All Californians are asked to reduce their use of lighting, adjust their air conditioning thermostat to 78° F or higher and postpone using major appliances until after 7 p.m.

Why Would Electrical Power Reserves Be Low?

Reasons for low reserves may include:

  • High peak demand
  • Unplanned generation outages
  • Transmission line overloads, losses, or limitations that can sometimes occur as a result of fires
  • Adverse, hot weather

Does Conservation Work?

Yes! Read about how conservation helped bring down record-breaking demand on Monday, July 24, 2006. (PDF)

Sign-up for Demand Response Programs offered by your utility

Demand Response Programs typically provide incentives and other benefits to customers who can reduce their power when energy supplies are low. These programs help ensure reliable and affordable power for all Californians and are available to most commercial customers and some residential customers.
