In the three years since deadly blackouts paralyzed Texas, two major winter storms have hit the electricity grid without plunging the state into blackouts.
Emergency Alert status from 7:30 pm to 9 pm Sept. 6 and asked Texans to curtail power demand from 5 pm to 9 pm Sept. 7 amid a persistent heat wave. Power markets responded with triple and quadruple-digit pricing.
The Electric Reliability Council of Texas (ERCOT) on Sept. 6 issued an Energy Emergency Alert 2 (EEA 2) after grid conditions quickly deteriorated around sunset (7:30 p.m.) as demand soared and operating power reserves plunged. The grid operator said that the emergency operations were necessary “due to a combination of dropping operating reserves and frequency.”
The grid’s regulatory body could approve a redesign of the ERCOT market on Thursday.
