From Redding to Riverside it was a scorcher this week. The National Weather Service issued “red flag” warnings for much of the Sacramento Valley, the Delta, and Lake Tahoe. Even San Francisco rated a heat warning. The California Independent System Operator’s electricity demand peaked on Thursday, August 28 at 45,330MW. On August 23, peak load was 35,799 MW; August 24 it was 38,921 MW; August 25, originally estimated at 42,169 MW, the peak was revised to 43, 131 MW; August 26, 42,590 MW; August 27, 43,350 and August 28 at 44,303 MW. Early in the week the Los Angeles Department of Water & Power asked customers to conserve. The week began with a soaring peak of 5,401 MW. The Sacramento Municipal Utilities District territory expected to see peak loads in response to a high of 103 degrees on August 28. Earlier, the muni’s weekly peak load hit 2,742 MW when the thermometers hit 100 degree on Wednesday, August 27. “We expect to eclipse that today but still expect to be shy of 3,000 MW–and about 300 MW short of the all time high,” said SMUD spokesperson Chris Capra. It is suppose to cool off Sunday and Labor Day, with temperatures expected in the low 90s later in the week.
