@Miedoambiente @ExtinctionR What are you paying for retail electricity in Spain? It's somewhat tricky to find retail prices partly because it appears Spain has time of day pricing.

This suggests it's dirt cheap, at least today (9.68 to 16.44 euro cents/kWh):

Ember's figures suggest 0.23-0.29 EUR/kWh in January, and other sources give a wholesale price of EUR 71.17/MWh for January.

Lets compare that to the UK.

The average wholesale price over the last year is £76.95 (around 90 EUR), but that doesn't have much to do with the retail price for various reasons.

From April to June we will pay 24.67p/kWh, which is around 0.28 EUR/kWh.

So if USwitch's figures are credible, Spain is indeed dirt cheap for electricity, at least today (presumably high winds/solar!). Not necessarily for other forms of energy. If we use Ember's figures it's still typically lower than the UK.

Although I'm not comparing standing charges here. Spain's standing charge is higher than ours for a typical home (about 240 EUR vs 310 EUR), but the standing charge is banded by size (unlike ours).
