True, and it's also one of the most efficient means of energy storage. The largest such power station in the UK (and still, I think, in the world) is at Dinorwig near Snowdon. It can produce just under 1.8GW for a little over 5 hours, for a total capacity of 9.1GWh (when it was built in the 80s, the idea was to cover sudden surges in demand, like millions of kettles being switched on at half-time in the Cup Final), ~50x greater than the upgraded Aussie battery setup I mentioned. So 15 to 20 Dinorwigs could power the UK grid for 5 hours - 3 or 4 hundred would be needed to cover for those 4 cloudy, windless, winter days. Grid scale energy storage is hard (effectively impossible with current and foreseeable technologies).
