Scotland can provide, at most, less than 5% of required capacity if you turned every available loch into pumped storage. Claiming that pumped storage is in any way a viable grid-storage system that can handle baseload in the UK is inaccurate. Even if every battery production facility on the planet was dedicated entirely to producing storage batteries for the UK it would take almost half a decade to meet the requirements. You can claim that more will be built, but there are resource pipelines involved that are not as elastic and just throwing a pile of money at someone to build a factory. Battery production is growing, but nowhere near fast enough to meet the requirements for grid scale storage. Right now fission has no competition from renewables+storage because the storage part of that equation remains a fantasy.
