"The CAISO is one of the largest ISOs in the world, delivering 300 million megawatt-hours of electricity each year and managing about 80% of California's electric flow." https://en.wikipedia.org/wiki/California_Independent_System_Operator https://en.wikipedia.org/wiki/California_Independent_System_... Right now, 3PM in California, the CAISO demand shows around 21GW of demand. http://www.caiso.com/TodaysOutlook/Pages/index.html http://www.caiso.com/TodaysOutlook/Pages/index.html Note that CAISO's peak, ever, was 50GW. (PDF) http://www.caiso.com/Documents/CaliforniaISOPeakLoadHistory.pdf http://www.caiso.com/Documents/CaliforniaISOPeakLoadHistory.... The "installed capacity" of 80GW I believe is the number if you add the theoretical max of all hydro, solar, wind, gas peaker plants, etc. But each source will never simultaneously be at max, so we never get close to this 80GW number. https://www.energy.ca.gov/data-reports/energy-almanac/california-electricity-data/2020-total-system-electric-generation/2018#:~:text=California%20has%20approximately%2080%2C000%20MW,and%206%2C000%20MW%20from%20wind https://www.energy.ca.gov/data-reports/energy-almanac/califo....
