Grid managers at the Electric Reliability Council of Texas (ERCOT) were forced to move to stage 2 emergency measures Wednesday evening when record-high power demand threatened to overload the system as solar power declined with the setting sun and the state’s fleet of wind generation delivered lower-than-expected inputs. A check of ERCOT’s data at 7:29 CT, a few moments following its stage 2 emergency notice showed that thermal generation consisting of natural gas and coal-fired units was accounting for more than 82% of overall system generation.
The Daily Caller reported that Wednesday’s emergency, combined with forecasts of 100+ degree high temperatures across most of the state Thursday and Friday, led Biden Energy Secretary Jennifer Granholm to issue an emergency order allowing ERCOT to exceed emissions limits to continue to input increased thermal inputs to preserve the integrity of the grid. While Granholm’s declaration is commendable, it is key to point out that the arbitrary emissions limits imposed by DOE on the Texas and other regional grids play a large role in creating the lack of grid stability in the first place.
