How Drumjohn compares
At a typical UK load factor for this technology (about 35% of the maximum possible output), a 1 MW station would generate roughly 3.1 GWh of electricity in a year, similar to the annual use of about 1,140 homes at 2,700 kWh each. This is an illustrative estimate, not the station's metered output: real generation varies with weather, availability and grid constraints.
Hydroelectric stations generate electricity from water flowing downhill through turbines, either from a reservoir behind a dam or from a river (run-of-river). Most UK hydro capacity is in Scotland and Wales.
