California ISO issues Flex Alert for Today, August 17

By the California Independent System Operator

The California Independent System Operator (ISO) has issued a statewide Flex Alert, a call for voluntary electricity conservation, for today, Aug. 17, from 4 p.m. to 9 p.m., due to predicted high temperatures pushing up energy demand and tightening available power supplies.

With above-normal temperatures in the forecast across much of the state tomorrow, the power grid operator is expecting an increase in electricity demand, primarily from air conditioning use, and is calling for voluntary conservation steps to help balance supply and demand.

Consumers are urged to conserve electricity, especially during the late afternoon and early evening, when the grid is most stressed due to higher demand and less solar energy.

Reducing energy use during a Flex Alert can help stabilize the power grid during a time of tight supply conditions, and prevent further emergency measures, including power outages.

Conservation Tips

Today, before 4 p.m., Californians should:

  • Pre-cool home by setting the thermostat to as low as 72 degrees
  • Use major appliances, including:
    • Washer and dryer
    • Dishwasher
    • Oven and stove for pre-cooking and preparing meals
  • Adjust blinds and drapes to cover windows
     

Today, during the Flex Alert from 4 p.m. to 9 p.m, Californians should:

  • Set thermostat to 78 degrees or higher, if health permits
  • Avoid using major appliances
  • Turn off all unnecessary lights

  1. I’ll believe Californians are serious about electric vehicles when they build out all the infrastructure needed and are honest with everyone that future needs for electricity outstrip the projected growth of renewables
    Californians like to outsource polluting activity to other states, countries so we can be sanctimonious
    Californians use 2 trillion cubic feet of natural gas per year and only produce 163 million cubic feet.
    Californians import natural gas to generate electricity and Natural gas is projected to lead all other methods of power generation within the state until at least 2050. Longer if electric cars beat projections
    Californians import 30% of our electricity from other states and that number is projected to go way up as electric vehicles become ubiquitous
    Californians produce 463,000 barrels of oil a day and use 1.8 million. Most of that from overseas, so it comes on fuel burning tankers.
    25% of Cailfornians electricity is provided by wind and solar. Projections say that number should continue to climb, but will not climb as fast as Californians demand for electricity. In other words, even as wind and solar grow, they will flucuate around a 25-30% supply to the demand.

  2. Diablo alone produces nearly double the electricity generated byall wind power and 2/3 of what all of solar does.
    Another way to put it would be that 10 Diablo Canyons would produce 100% on Californians current needs.
    I think we should be facilitating research into things like Thorium molten salt reactors
