California has gone to a Stage Two electrical emergency for the first time this year.
Residents and businesses are being asked to conserve energy use between the peak hours of 3 p.m. and 6 p.m.
It´s the second time in two days that energy officials have called an electrical emergency. Yesterday, they called a Stage One alert, which is not quite as serious.
The California Independent System Operator says record triple-digit temperatures in the valleys are draining reserves.
A Stage Two alert lets power grid managers get power from “interruptible” customers. Those are industrial and commercial power users who agree to scale back electricity use during emergencies in return for lower energy rates.
Rolling blackouts could be declared if a Stage Three alert is reached.
