asked the Secretary of State for Energy if he will indicate the generating capacity of the Dinorwig pump storage station, and make a statement on the feasibility of building further such facilities in the United Kingdom.

The declared net capability of the Dinorwig pumped-storage station is 1728 mw sent out. The Central Electricity Generating Board advises me that its system requirements for the foreseeable future do not require the addition of further pumped storage capacity.
