ERCOT sees new power demand records during sub-freezing weather

The Electric Reliability Council of Texas (ERCOT) broke its own electric power demand records as Texas customers called upon their heaters to get them through extremely cold weather January 7.

ERCOT, which controls the power supply of 85 percent of Texas’ population, reported that electricity demand hit a peak of 57,277 MW at 8 a.m. Central.

This demand peak exceeded the 57,265 MW record set in February 2011 during a cold spell that caused more than 150 power plants to go offline.

January 6, 2013, ERCOT declared a power emergency and the grid operator said it narrowly avoided rolling power outages by calling upon demand response resources.

Increased wind power generation in the western part of the state as well as sufficient power generation buoyed the ERCOT power reserves January 7, which led ERCOT to call off its power conservation alert.
