Before you build a wind farm, it’s important to monitor the wind resources at your proposed site. Wind speed is the single most important factor in how much energy a wind farm can produce and therefore determines a project's viability. Gathering good quality, reliable wind data is also essential in presenting a firm business case to your investors and other stakeholders such as the wind turbine supplier.

It's important to start wind monitoring early in the development process, as you need data for a minimum of one year in order to capture seasonal effects. You must do sufficient research during the pre-feasibility stage, as wind monitoring is a significant investment for community groups.
