flex alerts

Flex Alerts

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.

Visit FlexAlert.org for conservation tips, to subscribe for Flex Alerts and more.
