Today's Energy Outlook

A Flex Alert is typically issued in the summer when extremely hot weather pushes up energy demand as it reaches available capacity. This usually happens in the evening hours when solar generation is going offline and consumers are returning home and switching on air conditioners, lights, and appliances.

About The California ISO

The ISO manages the flow of electricity across the high-voltage, long-distance power lines that make up 80 percent of California’s and a small part of Nevada’s grid. The nonprofit public benefit corporation also operates a competitive wholesale energy market, and conducts transmission planning to identify grid expansion needs.
