Often the high costs of "curtailment" are inflated by counting the cost of gas plants in England that run to fill in for transmission blockages.

Of course, if the previous government hadn't effectively banned onshore wind in England, the cheapest source of energy available, you'd be able to deliver that energy for a quarter of the cost.

And, for extra added irony, this is an occasion that the classic "the wind doesn't always blow" line backfires, as either a) if it's windy in Scotland then it will be windy in England avoiding the gas cost or, b) the wind across that distance is decorrelated and you can displace even more expensive gas from the grid.
