California ISO Extends Statewide Flex Alert through Thursday

Due to continued high temperatures in the state, the California Independent System Operator (ISO) is extending its Flex Alert through tomorrow evening. The Flex Alert is a call for voluntary electric conservation from consumers during peak usage times from 2 p.m. to 9 p.m.

Electricity supplies statewide are predicted to continue to be tight due to high summer temperatures driving up demand, power plant outages, and transmission line import capacity reductions. Power imports have been limited today through tomorrow because of high temperatures in neighboring states.

Consumers are urged to continue conservation measures today and tomorrow, especially during the late afternoon when air conditioners push power consumption to the highest point of the day. Find Flex Alert tips at

Grid operators are monitoring conditions closely around the clock to ensure reliability. For current supply and demand conditions, visit “Today’s Outlook” on ISO’s website here.
