The problem with more pumped storage is geographical. You need a suitable small lake near a much larger one with several hundred feet of height difference. Dinorwig, Cruachan and Loch Ness are about the only places suitable.
For something of the scale of Dinorwig perhaps so - but (around my way at least) there are lots of places where there are two or three reservoirs next to each other down the same valley (think Ladybower/Derwent/Howden for example - but there are many others) - which might provide scope for smaller schemes (if at the expense of a little maximum water capacity - although that's probably already on the cards anyway from a flood alleviation point of view).
