It is the amount you have to pay the last (most expensive) fast gas 
turbine to come online to meet demand. And yes all the other suppliers 
of electricity get that final top whack price for their electricity too.

The UK market is rigged in favour of the producers of electricity. It 
makes green energy Very profitable here since there is no fuel cost once 
it is installed. Capital investment is huge but running costs low.

I don't understand your question. UK is fourth line down 31.2p domestic 
and 29.6 industrial (the latter being a huge outlier cf EU competitors).
Only the UK punishes its industrial base in such a manner.

More accurately most sensible countries allow their big industrial users 
to buy electricity at a price related to the total cost of production. 
UK pricing anomaly stems from the dash for gas tightly coupling 
electricity prices here to the spot wholesale price on the gas market. 
It used to be smoothed out by having bulk storage at Rough (but they 
closed that). It made sense to some bean counters at the time.

Ukraine war and Russia turning the gas taps off really set the cat among 
the pigeons see the second price vs time graph. The only reason that it 
didn't go even higher was government intervention. Obtaining enough gas 
during the first winter was touch and go. Lucky it was a very mild winter.
