Summer Readiness and Flex Alerts
The ISO encourages all Californians to learn more about the ISO's summer outlook, and how consumers can do their part during a Flex Alert.
The California ISO is forecasting tight energy supplies during high-use times in the summer of 2018, especially during the evening hours of hot days. While the likelihood of system-wide power outages is low, the ISO is asking for consumers to help during times of grid stress by answering the Flex Alert call to conservation. When consumers conserve at critical times, operators can better balance the grid and prevent more dire emergencies, including widespread power outages.

In its annual 2018 assessment, the ISO predicts conditions to become challenging in the evening hours, as California’s abundant solar supply declines during sunset, at the same time consumers return home from work and turn on air conditioners and other appliances.
A Flex Alert is a call for consumers to voluntarily conserve electricity when there is a predicted shortage of energy supply, especially if the grid operator needs to dip into reserves to cover demand. When consumers reduce electricity use at critical times, it can prevent more dire emergency measures, including possible power outages.
