Usual range: where 80% of this window's prices fell over the last 90 auctions. Next offer: the cheapest single-window offer rejected as too expensive. MW within £1: rejected capacity bid less than £1/MW/h above the price. Together they show how quickly the price would move if NESO needed more. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
