CAISO Issues Flex Alert for October 15, 2020
The California Independent System Operator (ISO) which manages the State's power grid issued a statewide Flex Alert, a call for voluntary electricity conservation for Thursday, October 15 from 3 p.m. to 10 p.m.
The Alert was issued for a possible energy supply shortage due to unseasonable high heat leading to an increased electricity demand late in the day. Consumers can actively help by shifting energy use to morning and nighttime hours and conserving as much energy as possible during the late afternoon and evening hours. Consumer conservation can help lower demand and avoid further actions including outages, and lessen the duration of an outage.
Consumers are urged to lower energy use during the most critical time of the day, 3 p.m. to 10 p.m., when temperatures remain high and solar production is falling due to the sun setting.
Extended periods of heat also can cause generator equipment failures that can lead to more serious unplanned losses of power.
CAISO and VPU recognizes that reducing energy use during the hot time of the day is a hardship, especially for those working from home or with children schooling at home. However, if a large number of consumers do their part in small ways, conservation can make a difference.
Between 3 p.m. and 10 p.m., the ISO and VPU is urging consumers to:
- Set air conditioning thermostats to 78 degrees, if health permits.
- Defer use of major appliances.
- Turn off unnecessary lights.
- Unplug unused electrical devices.
- Close blinds and drapes.
- Use fans when possible.
- Limit time the refrigerator door is open.

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.
Consumers are urged to voluntarily conserve electricity to help avoid more serious steps to protect the power grid, including local rotating outages.
