How Green Knowes compares
At a typical UK load factor for this technology (about 26% of the maximum possible output), a 27 MW station would generate roughly 61 GWh of electricity in a year, similar to the annual use of about 22,780 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.
Wind farms turn the kinetic energy of the wind into electricity with turbines. Output varies with wind speed. Offshore sites usually see stronger, steadier winds than onshore sites and so generate more per MW of capacity.
