Feed-in Tariff

A portion of the income from a wind turbine comes from the Feed in Tariff. The Feed in Tariff, or FiTs, is a government scheme designed to encourage British land owners to generate their own renewable energy.

Whether you choose to use the energy from a turbine yourself or export everything directly to the National Grid, the government will pay the owner of a wind turbine a reward for every unit of clean energy produced for twenty years following installation.

Once your turbine is accredited by OFGEM, you will secure a fixed rate which  is secure for 20 years and will rise in line with inflation.

OFGEM accreditation is handled by Earthmill as part of the planning and installation process and we will aim to secure you the best possible rate.

 What will you earn in FiTs?

You can easily estimate your potential FiTs earnings by cross referencing your wind speed with the power rating of the turbine model you are interested in to find your annual production estimate. You’ll then multiply your annual production by the current FiT rate to arrive at an annual FiTs income estimate. For example:

225kW at 6.5 m/s produces 646,000 units of electricity per year. 646,000 x £0.045 = £29,070 p/a

*You may notice that some higher rated machines produce lower yields at lower wind speeds than some lower rated machines. This is because those models are designed for installation in higher wind speed areas which is why it’s vital to match the correct turbine to each site.
