To find out that we go right through the day, and get to 5 o'clock in the evening, before there is an emergency declared, knowing at that point that there were constraints on solar, obviously; constraints on the wind turbines; and that it does take a long time—anybody would have known, anywhere, the 10-hour time to get the coal-fired plant going, the slightly less time to get a gas plant going. Also, at that point they knew the assessments were wrong. Well, why did it take until 5 o'clock to work that out? What was magical about 5 o'clock? Why didn't they know at 1 o'clock in the afternoon—when they should have been able to see from some of the very good weather forecasting we get at the moment—what the temperatures were likely to be and anticipate what the demand could be?
