Current expectations are that wind turbines in the 200 to 250 KW class will attract a generation tariff rate of 18p per kwh (when averaged over the scheme lifetime). The FIT scheme will run for 25 years and unlike many of other tariffs (eg PV, small wind) this particular one will not reduce over time.
In addition to the Generation Tariff an Export tariff of 5p per kwh has been agreed with the major electricity suppliers. This value is likely to increase over time in line with energy inflation.
With a fair wind we expect the DWP-24 turbine to generate approximately £90,000 per year from the two combined tariffs.
