A common question from owners, asset managers and lenders of wind farm projects is "was the wind resource above or below budget for a certain period (i.e. month or year)?". It is a peculiarity of wind farm projects that once built and operational, answering this question becomes rather complicated due to the presence of wake effects and influence of uncertainties on nacelle anemometry, meaning that it is generally not possible or advisable to compare nacelle anemometry measured wind resource from the site to wind speed budgets formulated at the pre-construction stage (for example, using a met mast as part of a pre-construction energy yield assessment).
This poster will present a methodology used to formulate a wind speed budget that can be directly compared to nacelle anemometry measured wind resource at operating turbine locations by site adapting re-analysis data.
