The balance of plant forms an integral part of the wind farm system. Proactive balance of plant maintenance is a key aspect of a preventative maintenance regime.
Regular inspections of all balance of plant elements are required to ensure emerging issues are highlighted and remedial repair work is planned to avoid loss of generation.
