Using the wind resource and turbine type, scale and position determined at the earlier stages, we use our databases to assess the annual energy production from the wind turbine(s). For multiple wind turbine sites, at an extra cost, we can complete additional full energy optimisation modelling in order to position the wind turbines to maximise energy yield and minimise interference from turbulence losses – please contact us if you require modelled energy optimisation.We can then select the appropriate and realistic electricity export rate (or account for on-site energy use) to estimate the annual income that the turbine(s) will produce. We also take into account maintenance, insurance and business rates to give you a realistic income estimate after operating costs.We will also provide a budget cost estimate for the whole project, including the remaining feasibility stages, obtaining planning consent and then the design and installation of the system.
