There were certainly some odd things happening during the Beast. I noticed that significant generation was by OCGT, which is normally considered an emergency source given the cost per unit. The total UK demand wasn't especially high for a winter day. This might be explained by the French and/or Dutch suddenly suspending supplies via the interconnectors, and indeed calling on the UK to supply emergency power. I can't remember the status of the various interconnectors at the time though.
