On Monday, early in the morning, they put out a notice, which wasn't a great alarm; it was just "Be aware that we think that we need some more generation bids." Then, by lunchtime, by around 1 o'clock, they put out a more serious notice and said, "Look, we really could need some more juice here." Then, in the absence of getting that required balance between generation and demand, they had to take emergency measures later that evening, telling the distributors of electricity to shed load in order to protect the system overall from collapsing. Some of the questions that need to be answered, as Barbara Kuriger rightly asked, is: was there proper communication with Ministers' offices? And those are proper questions to ask. I would make the point that irrespective of what the communication with offices should have been, it wouldn't have changed the practical outcomes on the evening.
