The issue is so called energy market, where electricity LOT price is set to MAX LOT price for all LOTS at that time slot if all lots are bought (peak hours when all generation is consumed). So in peak hours everyone gets max price of gas powerplant, all electricity selers happy (wind gets 4000 EURO/MWh, solar get same, everyone!) and the sucker on the wire end pays the bill/factories go dark. This stock algorithm with high gass price is exploading EU now.

This isn't the case in the UK? You can be billed for peak and off-peak prices if you wish, but if you're billed like this it often costs more because you end up paying more for peak use. Where as the standard price charged as a weighted average of the two.
