My Lords, the noble Lord mentioned pumped hydro. He will be aware of the role played by the Dinorwig scheme, which in its day was the largest in the world, although it is not quite that now. Are there more such schemes, and are they geared to the two-lake solution or to estuarial pumping, back up the valleys from where the rivers came?
