When stage 3 was first enacted on August 15, the CAISO power grid had 8.9% available resources, about three times the required threshold. On September 6, 2022, during one of the longest and hottest September heatwaves on record, which encompassed multiple Western states, California's peak electricity demand of 52,061 megawatts occurred.
In August 2020, during a heat wave which affected the entire West coast, air conditioning usage caused the peak load to hit 47 GW, and CAISO issued rolling blackouts to avoid a larger system shutdown. The state did not have enough generation ready to fulfill demand, and it was unable to import sufficient electricity from neighboring states who ...
A crucial part of this curve comes from the net load ("the difference between expected load and anticipated electricity production from the range of renewable energy sources"). [5] In certain times of the year (namely spring and summer), the curves create a "belly" appearance in the midday that then drastically increases portraying an "arch ...

Hourly graph of total CAISO electric demand (green), demand without solar and wind generation (purple), solar (yellow) and wind (blue) generation on May 23, 2023. Note the duck curve's steep rise from 17:00 to 18:00 as the sun sets, requiring some 5 GW of natural gas production to come online within an hour to supply peak demand by 20:00. [13]
In addition to the main unit, three 52 MW diesel powered peaking generators could be brought online in four minutes and to peak load in ten minutes notice to meet extra electricity demands as specified by the California Independent System Operator. They were generally operated for only a few hours at a time, usually during peak power ...
The peak load in 2022 was 147,820 MW on July 20. [37] PJM forecasts peak load to increase to 160,971 MW in 2033 and reach 167,567 MW in 2038. [ 38 ] As of June 2022, PJM’s stated capacity was 198,152 MW, [ 39 ] which is substantially greater than any peak load ever experienced, or any peak load forecast.
