ISO appreciates consumer conservation; reminds of Flex Alert tomorrow

FOLSOM, Calif. – The California Independent System Operator (ISO) announced that consumer conservation helped grid operators avoid rotating power outages today.

The grid operator earlier declared a Stage 2 Emergency, when wildfires took 1,600 megawatts (MW) of resources off the grid, however, conservation helped avoid further emergencies, including rolling outages.

The ISO issued a Flex Alert to urge consumers to conserve energy during this statewide heatwave that's driving up energy consumption. The Flex Alert will continue on Sunday and Monday, with conservation needed between 3 p.m. and 9 p.m. each day.

Temperatures during this heat wave are expected to peak tomorrow, pushing demand for energy beyond levels of available supply. Based on the current forecast and without significant conservation efforts, the ISO is planning for the potential for rotating power outages throughout the state tomorrow between 5 p.m. and 9 p.m.
