How Garreg Llwyd (GB) compares

156th of 488largest wind farms in the UK register
12th of 43in Wales
0.10%of listed UK wind farms capacity
β‰ˆ 69 GWhillustrative output a year

At a typical UK load factor for this technology (about 26% of the maximum possible output), a 30.4 MW station would generate roughly 69 GWh of electricity in a year, similar to the annual use of about 25,640 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.
