It would likely converge on wind farm strike prices plus margin, so about 10p/kWh .. if you lived in Scotland or near the coast. Being a localized market I would expect to see higher prices in London.
But there's also a risk of spikes. You'd probably want a regulatory guarantee of maximum prices, I think during the Texas crisis it got over $100/unit at one point.
On a handful of days - such as yesterday [2] which was very windy - prices fell as low as -2.6p at 03:30
For comparison, a 'regular' energy supplier will charge 23.47p/kWh for anytime use.

So you generally pay more unless you become nocturnal or unemployed/homemaker?
And to quote the person to whom I replied: "If you put actual numbers on it, you would be able to have a sane discussion "
There is often an implication or assertion that the tech to enable surge pricing will actually enable way cheaper energy. So I want to know the estimated unit prices.
