>There could have been rules to decide which users are shed if production is too low (or put differently, prices are too high). Is that putting it differently? They aren't both sides of the same coin. One is essentially rationing to cap demand, one is pricing to cap demand. I believe some large energy users are on contracts that allow the suppliers to cut them off when demand is high, that's generally a short term measure though. The current problem isn't really one of supply in the traditional sense though, that's the issue. The market has been designed to deal with spikes when the England game finishes and everyone puts the kettle on, not multi month periods of high prices. It could no doubt be changed so that not everything is priced at the most expensive option, but there are probably reasons why that hasn't already been done.
