NERC matters: Should NERC impose winter preparedness requirements on generators?



During February 2011, the southwestern United States experienced unusually severe cold and windy weather, with many cities experiencing a 50-degree drop in temperature over an 18-hour period, with sustained winds of 30 to 40 miles an hour. During this period, generating units in the Southwest experienced an outage, a derate, or a failure to start, leading to controlled load shedding of about 5,300 megawatts.
