ISO Declares Stage 2 Emergency; Power Outages Possible in Contra Costa County


For the second day in a row, PG&E is encouraging customers to help prevent blackouts by conserving energy as rolling blackouts are anticipated Tuesday afternoon and into the evening.

Supervisor Diane Burgis took to social media listing Tuesdays anticipated times there may be blackouts in the City of Antioch, City of Brentwood, City of Oakley and City of Pittsburg.

It is anticipated that there may be blackouts in the following areas:

Antioch – 11410 customers – 4:00 PM – 7:00 PM
Brentwood – 7,996 customers – 4:00 PM – 7:00 PM
Clayton – 468 customers – 8:00 PM – 11:00 PM
Knightsen – 4 customers – 8:00 PM – 11:00 PM
Oakley – 9143 customers – 4:00 PM – 7:00 PM
Pittsburg – 4157 customers – 4:00 PM – 7:00 PM

Per PG&E: Record breaking heatwave strains the grid

During heat waves, the California Independent System Operator (CAISO), the organization that runs the state’s electric grid, can call for rotating outages statewide to protect the stability of the grid. Most utilities in the state – including PG&E have been called on to participate.

These outages should last between 1 to 2 hours for most customers. These are not Public Safety Power Shutoffs due to extreme fire danger, and are not related to any issues with PG&E’s equipment or its ability to deliver energy locally.

You can do your part to help prevent blackouts by conserving energy. Set thermostats to 78 degrees or higher. Run energy intensive appliances during early morning or after 9 p.m. Close drapes and blinds to keep rooms cool.

The ISO Declares Stage 2 Emergency; Power Outages Possible

The California Independent System Operator (ISO) has declared a statewide Stage 2 Emergency for Tuesday, Aug. 18, and is urgently appealing to consumers to conserve energy immediately to avert or limit power outages today.

If system conditions do not improve, the ISO will declare a Stage 3 Emergency, including rotating power outages.

The ISO is working closely with utilities and neighboring power systems to manage the strain on the grid and to limit any potential power disruptions.

The ISO also called a Flex Alert, a voluntary call to consumers to conserve electricity, from 3 p.m. to 10 p.m. today through Wednesday, Aug. 19. Consumers are urged during those times to set air conditioner thermostats to 78 degrees or higher, turn off unnecessary lights, and defer use of major appliances.

These conservation measures can help the power grid during a time of tight demand and supply. Reduced energy use during a Flex Alert can prevent further emergency measures, including the incidence of rotating power outages.

The ISO also issued a warning earlier today that encouraged energy resources to participate in the ISO market and allowed the grid operator to request utilities implement demand response programs to reduce residential and business electricity use.

For information on outage locations, timing, or health concerns, contact utilities or energy providers.

  1. I gind it funny that yahoo has blocked ALL comments on EVERY single story for the past month
    They don’t want the truth heard!!!
    Very FUNNY and FAKE!!!
    And the blackouts
    Where are they?
    And newsom says its windy?
    Where is he living?
    Its not windy!!!!!!

  2. The above states there may be, possibly be, outages, not that there, for a fact, certainly, will be outages. There’s too much negatively and incorrect stories on yahoo and a lot of media. It’s only making people feel more depressed and upset. I like not having the comments….then again, a lot of them are funny to read.

  3. uh ….No?! The loony libs told us for decades to do our heavy voltage usage in the evenings.. washing, running a/c and now charging our ac/dc/and foot-powered cars. but the genius darlings in Sac town have mandated upwards of 15% of our power grid to be on solar!


    PUFF, PUFF, PASS. yeah dude, (COUGH COUGH) global warming maaaaaan! now pass the cheetohs.


  4. The rolling blackouts are as a result of Californias push for “green energy” ISO has been warning the leaders of California that the supply of electricity is at risk and is under powered by 20%. The push to get rid of carbon based fuels like natural gas and the irrational closing of Nuclear power plants is insane. Nuclear power does not contribute to emissions and provides a lower cost supply of energy. With the push to go all electric when you don’t have enough power supply as it is?
    The governor needs to work with PGE to make continuation of Diablo Power plant feasible.
    when that plant goes offline. We will have 10% less supply and see an increase in our bills.
    The subsidies that we pay in taxes is the only reason green energy has the lower cost it does.
    We are subsidizing our own demise.
