The manager of California’s power grid is urging residents to voluntarily conserve energy through Wednesday as the state continues to ride out a record-breaking heat wave.
The California Independent System Operator also warned of more power outages in its statewide flex alert issued Sunday.
The heat wave “is causing a strain on supplies, and consumers should be prepared for likely rolling outages during the late afternoons and early evenings through Wednesday,” the ISO said in its alert, adding that there is not enough energy to meet the high amounts of electricity people are using in order to cool themselves down.
Residents are asked to lower energy use from 3 p.m. to 10 p.m., when temperatures remain high but the sun is weaker.
The ISO recommends setting air conditioning thermostats to 78 degrees, turning off unnecessary lights, unplugging electrical devices not in use, closing blinds and drapes, and using fans, when possible.
