it turns out some of those problems may have been because ERCOT had not winterized its system properly (but more on that in a minute). The Wall Street Journal spells it out:

Between 12 a.m. on Feb. 8 and Feb. 16, wind power plunged 93% while coal increased 47% and gas 450%, according to the EIA. Yet the renewable industry and its media mouthpieces are tarring gas, coal and nuclear because they didn’t operate at 100% of their expected potential during the Arctic blast even though wind turbines failed nearly 100%.

The policy point here is that an electricity grid that depends increasingly on subsidized but unreliable wind and solar needs baseload power to weather surges in demand. Natural gas is crucial but it also isn’t as reliable as nuclear and coal power.

Politicians and regulators don’t want to admit this because they have been taking nuclear and coal plants offline to please the lords of climate change. But the public pays the price when blackouts occur because climate obeisance has made the grid too fragile. We’ve warned about this for years, and here we are.

But the best evidence that ERCOT should be investigated comes with a report indicating that the small fraction of Texas not serviced by ERCOT seems to have had few outages at all. And it would appear it’s because they took the time to weatherize their systems following a 2011 winter storm that hit the state.
