California grid operator warns of rotating outages

NEW YORK: The California ISO declared a "Stage 2" power emergency late on Saturday, warning that rotating power outages were possible amid a record heat wave. A Stage 2 power emergency means the ISO has taken all mitigating actions but can no longer provide its expected energy requirements.

Temperatures of up to 125 degrees Fahrenheit (49 Celsius) were set to punish California through the Labor Day weekend, raising the risk of wildfires and rolling blackouts. California Governor Gavin Newsom on Friday declared a state of emergency, a proclamation that allows power plants to operate beyond normal limits through the three-day holiday weekend.
