How much electricity will a wind turbine generate?
The amount of energy available is highly dependent on the wind speed at hub height. Below 5 metres per second (m/s), there is generally too little energy available to justify the expense of a wind turbine, while the amount of energy available above that threshold increases rapidly. An estimate for windspeed in your area can be obtained from the UK national wind database, available on-line. If there is sufficient wind, you could then expect the following outputs from the Proven turbines we install. Note that actual output will vary, as these figures are based on optimal site conditions and an average ground wind speed of 5m/s. Turbine Size Annual Output 2.5 kW 2,500-5,000 kWh 6 kW 6,000-12,000 kWh 15 kW 15,000 – 30,000 kWh 1 kWh is equivalent to 1 unit of electricity on your electricity bill. Individual outputs will vary with weather experienced.
