The price of electricity in the UK is linked to the most costly supply in the entire mix. So if gas is the most expensive then we pay all other power-producing suppliers, regardless of means of generating, the wholesale price we'd pay for gas. It's a strange system.

It makes sense to extract honest bids. The lower you bid, the more likely you are to be paid. So in the long term, it leads to cheaper prices.

If for example you had a cheap source of gas when others put their price up, it would reward you making that info public.

Short term global fuel price spikes are a weak point, though.
