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.
