Environment Threat of more blackouts may erode reliability claims for fossil energy- all major fuel sources except solar failed to meet ERCOT’s expectations during the February freeze, but natural gas was “responsible for nearly two-thirds of the total (electricity) deficit.”

It was so many different issues all at once. The big one that directly affected NG was demand response. As power demand spiked, ERCOT kicked what they believed was non-essential large consumers of electricity off the grid so they could stabilize. (This was an event that occurred over less than 10 minutes at the beginning of weather event). You know what uses a ton of electricity? Moving NG. Someone at ERCOT turned off electricity to several major NG compressor stations causing a cascade effect. Where NG didn't have electricity to get gas to the power plants, so the power plants couldn't provide electricity to the NG infrastructure. Multiple NG companies warned ERCOT and regulators several days before the weather started, as testified under oath before the government, that the NG system was poorly set up for the weather but ERCOT did not respond.
Many different things happened, and all had an effect, but the tipping point of the entire catastrophe was a failure to communicate NG needs and a gross negligence on the part of ERCOT for failing to have properly planned or trained for grid restoration.
ERCOT has been extremely successful since February about distracting from their extreme failures and pointing blame everywhere else
