The only question is whether that estimate was fined tuned in the hour before each timewindow (as is usually possible) and whether the estimate shown is the one done a day before, or the fine-tuned one. I would expect it to be the day-ahead one, but maybe not.
(or am I missing something from the definition of estimate and "telemetered" production?) In the long run, we're all dead. John Maynard Keynes
Nope. The 9GW is the metered production, the 10.1GW estimate includes unmetered capacity. That's pretty good -- back when I first bookmarked this link years ago, the metered part was barely above 50% of the total capacity. *Lunatic*, n. One whose delusions are out of fashion.
