California ISO Declares a Statewide Flex Alert Due to High Temperatures

FOLSOM, CA--(Marketwired - July 27, 2016) - The California Independent System Operator Corporation (ISO) is declaring a Flex Alert, a request for consumers to conserve electricity today, especially during peak demand time from 2 p.m. to 9 p.m.

Electricity supplies statewide are expected to be tight because of high summer temperatures driving up demand, power plant outages, and transmission line import capacity reductions. Power imports may be limited today because of high temperatures in neighboring states.

Consumers are urged to conserve electricity today, especially during the late afternoon when air conditioners push power consumption to the highest point of the day. Find Flex Alert tips at www.caiso.com.

Outlook for July 27, 2016 Flex Alert

High temperatures are forecast for the entire state. Energy demand is expected to be high and consumers are urged to conserve electricity until after 9 p.m.

Outlook for July 29-30, 2016

Flex Alerts are part of an educational alert program that informs consumers about how and when to conserve electricity.

Flex Alerts

The California ISO issues a Flex Alert when the grid is under stress to meet demand caused by generation or transmission outages, or from persistent hot temperatures.

Flex Alerts call for voluntary conservation before the ISO needs to start using energy reserves to maintain reliability.

Conserving electricity helps avoid taking further steps to balance supply and demand, which could include in the extreme, local rotating power outages.
