ERCOT data showed renewable energy is not root cause of grid failure!

Do you think the issue was more the total outages or the lack of planning for what would happen during such outages? Is this a situation that may repeat itself and a more systematic solution should be investigated? 

Yi, I think you need to dig a little deeper to get to the root cause.

Wind power, which ERCOT has been hyping for years to distract from Texas's role as the largest carbon polluter in the country, was billed by the state's all-powerful oil industry as the "replacement" for coal.

That's what we were supposed to believe, anyway, as Texas built gas plants hand-over-fist to replace most of the retired coal generation. The artifice fell apart, however, when the state discovered its fragile, intermittent renewable props didn't work in cold weather - and it hadn't built enough gas plants, and gas transmission, to pick up the slack!

"As multiple experts have documented, the vast majority of power plant capacity outages in Texas are at gas generators."

What multiple experts haven't documented is why there were outages at gas generators. Did pipelines snap in the cold weather? Of course not - gas plants and transmission work just fine year 'round, anywhere from Bangor to Corpus Christi. But when called on to replace 18% of Texas generation, there wasn't enough transmission to deliver fuel to them - the state's shiny new gas plants had literally run out of gas.

That one week Texas was bragging about the robust part wind plays in its energy future, and the next can't minimize it fast enough, is comical. But as the laughter dies down, and we're faced with the sobering reality that scores of Texans lost their lives due to ERCOT's poor planning, it's time to take stock -  and recognize that power plants requiring a constant supply of fuel don't work when the supply is disrupted, and power plants that require wind don't work when the wind stops blowing. It's time to recognize that when Texas was faced with both circumstances at the same time, disaster could have been the only result.

No wind is the problem. Too much money was directed into an unreliable (and unneeded) energy at the expense of reliable generation. The quality of capacity reserve margins deteriorated as a distorted and ill-devised marketplace provided no particular incentive to maintain a properly prepared reserve margin.
