In light of the anticipated heat, the state's power grid operator is predicting an increase in the demand for electricity, "primarily from residential air conditioning use,' according to the California Independent System Operator.

Residents and businesses are being asked to reduce their energy consumption between the hours of 3 p.m. to 10 p.m. on Friday.

"California will be experiencing near-record or record-breaking heat, up to 10-20 degrees above normal in some areas,'' ISO officials said. "Prolonged heat over several consecutive days is expected to drive electricity demand higher, as nighttime temperatures are also forecast to be above average."
