As temperatures hit triple digits again on Sunday across much of PG&E’s service area, the state’s grid operator issued a Flex Alert for Monday and Tuesday.
The California Independent System Operator (CAISO) issued the Alert for Monday and Tuesday for Northern California due to excessive heat and a generation unit being offline.
PG&E customers are urged to avoid using heavy appliances between noon and 7 p.m. on both Monday and Tuesday. Grid demand is expected to peak at 48,300 megawatts (MW) at 4:30 p.m. on Monday and at 47,808 MW at 4:30 p.m. on Tuesday.
Other energy-saving tips from CAISO include:
- Turn off unneeded lights
- Use appliances after 6 p.m.
- Adjust air conditioners to 78 degrees or higher and turn off if away
- Pull drapes and turn on fans
- Set pool pumps for overnight use
- Saving water saves energy. Avoid using water between 4-6 p.m. on Flex Alert days.
According to PG&E meteorologist Mike Voss, the significant heat wave is expected to continue through Wednesday. A sea breeze brought some relief to the Bay Area Sunday evening, but interior valleys remained scorching hot.
Some high temperatures on Sunday included 101 in Ukiah, 110 at Redding, 105 in Vacaville, 94 in Santa Rosa, 89 in San Luis Obispo, 106 in Modesto, 109 in Fresno and 106 in Bakersfield. Death Valley, which is not in PG&E’s service territory, hit 128 degrees.
Over the weekend, PG&E crews did restore power after some heat-related outages occurred.
PG&E provides funding for cooling centers in some areas. Customers should contact their local city or county for addresses and hours of cooling centers in their home towns.
