No it isn't. Storage capacity for energy is expensive, if you want to have a grid that is largely dependent on intermittent sources and still have a stable grid providing power at all times you need large amounts of storage as well as generating capacity.

For example if nuclear costs 1bn for a GW and solar+wind costs 0.6bn but you need to also install 0.5bn of storage to make the grid reliable to the safety margin you deem acceptable then it is no longer a cheaper system.

Amount of storage needed scales up rapidly as you get towards an grid with entirely intermittent generation.

OTOH solar is a lot less useful in the UK than in the US. The southern tip of the UK is north of all the major Canadian cities, in the depths of winter we get about 6 hours of daylight with the sun barely reaching 20 degrees above the horizon. The winter is also where most electricity usage is too, doubly so when you want to replace gas heating with a heat pump. No AC and summer daylight past 10pm means that residential electricy usage in the summer, when solar does make sense, is very low.

They assert that they dont have them, in the same way you (presumably) assert that you do have them. Neither have any further evidence and one is not a prioi more likely than the other.
