For third straight day, conservation prevents power outages during heat wave
FOLSOM, Calif. – For the third consecutive day, the California Independent System Operator (ISO) said consumer conservation efforts had averted rotating power outages, even though energy supplies were tight.
Imported energy and increased wind production also helped the grid with additional resources.
The ISO thanks California consumers for their conservation of power in the afternoon and evenings during persistent high temperatures. California's record-breaking heat wave has put strain on the ISO electric system since Friday, Aug. 14, as air conditioners pushed up electricity demand.
In an effort to prevent or limit power outages during this heat wave, the ISO issued a statewide Flex Alert, a call for voluntary electricity conservation, until 9 p.m. tonight.

A Flex Alert is issued by the ISO when the electricity grid is under stress because of generation or transmission outages, or from persistent hot temperatures. Glossary of terms and acronyms
