Spain is not often noted for leading the way but their new pricing for electricity, which has three price periods per 24 hrs, and includes weekends, seems better than the UK's E7 system.

This along with proposed surge pricing (for periods of high demand which could have had user agreed load shedding) was the great opportunity that the UK government managed to waste with the superfluous (and entirely passive) smart meters.

The irony is that Spain started this to lay the way for electric car charging overnight but if take-up is big, then the high power cars will suck up might make usage overnight a high price rate period! Not many people will want to drive at night and charge during the day to save money!
