The California ISO has issued a statewide Flex Alert, a call for voluntary electricity conservation, beginning Saturday and extending through Monday, from 3 p.m. to 9 p.m., due to excessive heat in California.

On Saturday California ISO tweeted that "#Powergrid is staying at Stage 2 emergency. No outages yet. Conservation efforts are key! #KeepConservingCA #ItsWorking #FlexAlert until 9 p.m."

"It's going to be another extreme heat event this weekend. Watch for calls for #electricity conservation and be thoughtful about energy use on high heat days. Visit http://FlexAlert.org for energy saving tips," California ISO said on Twitter Thursday.

Here are a list of cooling centers open across LA County.
"Labor Day weekend temperatures are forecast 10-20 degrees above normal for California, and the power grid operator is predicting an increase in electricity demand, primarily from air conditioning use. Overnight temperatures statewide are projected to be at least 10 degrees higher than normal, which doesn’t allow infrastructure to cool down. High heat is also predicted throughout the West for the weekend, which can limit the ISO’s ability to import energy to serve demand," California ISO said in its press release.

A Labor Day weekend heatwave means Southern California could be in for more rolling blackouts.

"Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities." warned an NWS statement in a CNS story.Peak heat expected Sunday.

Between 3 p.m. and 9 p.m., the ISO 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.

Consumers can also take steps to prepare for the Flex Alert by doing the following before 3 p.m.:

 “Pre-cool” their homes, or lower air conditioning thermostats.

Charge electric vehicles.

 Charge mobile devices and laptops.

Run dishwashers, washing machines and other major appliances.

Set pool pumps to run in the early morning or late at night.

With temperatures in some parts of the region forecast at over 100 degrees, the state is already planning for the heat wave. Brian Ferguson with the Governor’s Office of Emergency Services told KCBS Radio that one of the challenges of the widespread heat wave is that the state’s energy moves back and forth between states.

"We’re working closely with the investor-owned utilities on some actions that they can take, as well as some of the state’s larger power users who use a large percentage of the grid to take their energy use now," Ferguson explained.
