Probably the cheapest and best option is to build more wind and not care too much if it increases curtailment.
Yes, all the things mentioned should be looked into and done when it makes financial sense but "wasting wind" is much less a thing to worry about than "burning gas", and I'd rather waste wind than waste money.
The article wasn't decrying the existence of excess wind power, it was trying to describe the best solutions for using that power.
But all the solutions are aimed at reducing the curtailment of wind. Rather than reducing the gas burnt.
If the money saved by building more wind (or solar) and not having to burn gas saves more money then who cares if more wind is "wasted"?
It would be nice to use every last drop, but I dont want to actually spend money to achieve that goal when it could be used to e.g. build yet more wind, and burn even less gas.
The article describes an entirely different problem than "oh no, it's very windy/sunny and we don't know how to use all of this energy" which is not solved with better distribution, but with storage and demand regulation.
And actually, the article is in complete agreement with you that we needn't be overly worried: curtailment isn't the end of the world, but we can solve it and it turns out that some of those solutions are cheaper than just building more farms, or would incentivize building those farms closer to where the energy is needed.
I'm explicitly calling for more curtailment, because it isn't a problem and doesn't need to be solved.
Burning fossil fuels is a problem to be solved. High electricity prices are a problem to be solved.
Both of those problems can be solved by building more wind power, which almost inevitably increases the amount of wind curtailed.
To repeat, curtailment is not a problem and does not need to be solved. It's a normal part of running a renewable grid. Any low cost renewable plan will have some predicted degree of curtailment, because it's the cheapest way to meet our energy needs.

That’s because curtailment does cost us money. Someone’s paying those wind operators to turn off the farms. We literally pay money to wind farms to explicitly make them produce nothing.
How do you reconcile these two statements?
> High electricity prices are a problem to be solved.
> I'm explicitly calling for more curtailment, because it isn't a problem and doesn't need to be solved.
Curtailment cost money, you still need pay the wind operators to the energy you told them not to produce, plus pay someone else to produce the energy that’s now not being produced by wind. That cost ultimately ends driving up the price of electricity.
You want to reduce the cost of electricity, a good start would be not paying people for electricity that can’t be used.
> Both of those problems can be solved by building more wind power, which almost inevitably increases the amount of wind curtailed.
Only if you can transport the energy. Otherwise you’re just building turbines that can’t be used, and paying for the privilege of not using them.
Why? What are the real costs? Isn't it just a simple disconnect switch? Why do the wind operators get paid for not delivering power? Is it a contractual issue?
One of the big points in the article is that there’s a single energy market in the UK that doesn't consider location. So it’s possible for wind providers to sell energy from locations where it can’t be used. An obvious fix is to introduce multiple energy markets for different locations, so the price of electricity drops in areas where there’s excessive production, and not enough transfer capability.
Perhaps the system could be changed to be more like how you imagine it should work, or would prefer that it would work.
But not understanding how it does work and jumping off from there on the discussion means that folks end up talking past each other, rather than actually communicating.
I used to work for National Grid in the Miliband era; I worked, among other things, on theorizing a replacement to the 'circle diagram' for the (then thought to be) coming renewables regime.
> This isn't a real economic loss.
Perhaps I'm misinformed on what economic loss is. To me, paying for something and not getting it is a loss.
I go to movies, I buy popcorn, I spill popcorn. Movie theater says "tough noogies" to me that's a simple economic loss, and roughly the same. I paid for it, I didn't get it.
Worse still is paying for curtailment on both sides. From the article:
Consumers end up effectively paying three times for the power they’re getting: the original payment to the windfarm for the electricity, the payment to turn off, and then the payment to the alternative generator.
If this is true, and you're both paying a turbine operator for the power, and then again to not produce the power, well that's extra worse. That would be the initial economic loss (I paid for the thing and didn't get it) with an fee tacked on top.
I go to movies, I buy popcorn, I spill popcorn. Movie theater says "tough noogies" to me and doesn't replace the popcorn. They also charge me a fee for cleaning up the popcorn I spilled. That's worse from what I can tell.
Again maybe I don't understand what's going on here with respect to how precisely curtailment works. But it's hard to imagine that the situation
> So the grid has to pay them for electricity, even if they can’t use it.
is anything other than an economic loss.
> Claiming it is, is tantamount to saying that if you don't need to go to hospital while on vacation, you have wasted money on travel insurance.
I see where you're going with the example. I don't think insurance is a good example though, because insurance is decidedly different, at least to my mind.
If you pay for insurance, you got insurance. You're not prepaying for medical treatment, you're paying a small fee to be made whole again if the trip goes sideways. If you paid for insurance and didn't need to use it, you still were insured and got the peace of mind that comes with knowing you either A) have a great time on your trip or B) don't pay for an entire trip that you don't get.
Paying for curtailment is directly paying for something that you directly don't get. No intermediaries, no risk model, no nothing.
If I'm failing to understand, well, OK then! Great! Please do inform me. You rightly stated that I called you misinformed without backing it up. If you're going to say that your original example is obviously correct, maybe try explaining it then?
