I don’t understand the reason for the triple cost for curtailment. Like it seems the obvious options would be:

- pay $x for y joules of wind

- pay $x for y joules of gas; ask wind farm to generate y joules less and pay them $x +/- epsilon for the lost income. Total cost: $2x

I would have guessed that if you’re a big generator then your national grid contract would say something like ‘you turn off when we say so but we’ll pay you for lost revenue.’ I don’t understand why the wind farm, according to the article, is paid twice, both for the energy (not) being generated and to turn off some generation?
