Indeed! That's including available wind generation that was curtailed (not used) due to transmission constraints. So it's the actual output plus the amount of output that was "lost" because we had to switch off some wind farms, even though the wind was there to generate more.

Apparently they've announced some plan to sell this power cheaply to local people on the same side of the bottleneck, though I've not seen the details yet.

Seems to be another one of those sensible ideas that needs a global crisis to be pushed through to reality.
