If (possibly when, as they are looking into it now) the UK moves to zonal pricing, Scotland will have the cheapest electricity in Europe, due to all the wind.

All the other zones would reduce in price too. Currently you get some oddities like France buying cheap wind from Scotland and since it can't get delivered through bottlenecks, gas plants in England supplying the power.

The cost of this gas is then the source of headlines about how expensive wind backup is, rather than headlines about why Scotland has mysteriously more cheap electricity than England, where onshore wind was effectively banned, and the problems caused by different areas having different amounts of cheap electricity and a single market price.
