According to California ISO, a heat wave is causing record-high power demand.

In California, where temperatures are rising,

 the demand for electricity is getting close to records.

In order to prevent disruptions, the state grid operator increased

its requests that users use less electricity in the afternoons and evenings.

"We are facing a load forecast of 48,817 megawatts and energy deficits between 2,000 and 4,000 megawatts for Monday,

 resulting in the highest likelihood of rotating outages we have seen so far this summer,

" California Independent System Operator (ISO) said in a statement.
