Flex Alert Declared

State officials have called for a Flex Alert from Tuesday, July 8, to Thursday, July 10. Due to the current hot weather, electricity conservation is necessary.

With a significant heat wave bearing down on California and the West this week, and with more than 300 wildfires still burning state-wide posing potential threats to the state’s power grid, the California Independent System Operator (CAISO) has declared a Flex Alert.

CAISO expects to see the highest electricity demand of the summer this week, and it urges Californians to conserve energy, especially during the “AC rush hour” from 3 to 6 p.m.

CAISO says it does not anticipate any shortages this week, but it cautions that peak demand could approach the record peak demand of 50,270 MW, set July 24, 2006 (e-Newswire, 7/26/06).
