Heat lowers wind generation output

Today's Date is always found on calendarsHigh temperatures debilitate wind power generators



As found :

Texas taxpayers who have invested a great deal of money into wind, hot days are also the time when wind power generators don’t work very well.

High heat “keeps [wind] turbines from spinning”

Wind generation may peak at about 5,900 megawatts on Thursday [July 6] and 6,900 megawatts Friday[July 7], less than two-thirds of what they totaled a week earlier, according to grid manager Electric Reliability of Texas, or Ercot. ...

The only reason more Texans didn’t suffer from heat stroke that summer was that “fossil-fuel generators such as coal and natural gas plants” were available to step up their energy generation to meet the demand

States that use wind and/or solar to generate a substantial portion of their energy must retain multiple natural gas, coal-fired, or nuclear plants in reserve so that energy is available during “extraordinary” events such as the 2017 Texas heat wave.

And there is an odd thing that occurs sometimes when there is too much of this chaotic wind generated electricity supplied to grids, a negative cost, meaning that "the consumer is paid to use the power"。 For example in Texas on one hot day the cost of electricity fell to zero then "went negative to $8。52 per megawatt hour"。 That may sound fantastic, getting paid to use the excess electricity which creates visions of running the air conditioner at 65 degrees all day and night and getting paid for it but it doesn't work that way。 This is because of tax credits。 Where do those come from? Your tax bills you pay。 So on these rare days where this happens, well, you don't actually get that money the electric companies do and you are still paying for everything, but somehow, all the financiers and the pensions of those working in these industries get filled with these energy $$$。 Then there's the cost of building transmission lines that would handle the loads more efficiently, they cost more than the cost of generating the power。 In other words wind plantations use up more energy than they produce in every scenario。
