Is this electricity price correct?

This illustrates the challenge with having renewables in the energy mix.

The time point you show is for this afternoon with the sun down (so no PV) and limited wind output. The cost shown will be the wholesale price for buying power right now which indeed is very expensive. Anecdotally, one well known electricity supplier is incentivising domestic customers to use less electricity from 5 PM to 6 PM today - offering to PAY 72 p per kWh saved - this is how attractive some load shedding is, given the high wholesale price.

You get very different numbers already by looking at the whole day (0:00 to 17:00) - averaging a little over £500 / MWh (using the menu buttons at the top of the page).
