The trouble is the capacity is in the wrong place; the UK closed coal plants in (defunct) coalfields in the middle of the country, and built offshore wind farms which tend to be further north. There's plans for an offshore north-south connector to help with this.

True, but don't forget you can put BESS on the sites of the old coal plants: https://www.bbc.co.uk/future/article/20240927-how-coal-fired...

That connector goes underwater right where I grew up. I haven't visited mother for a few months but afaik they haven't begun digging yet.
