Once a wind farm is in operation the site is monitored remotely.  Maintenance staff visit the wind farm on a quarterly basis for routine works.  The control systems in the turbines are fail-safe, so if a fault does occur the turbines stop automatically and communicate with the operating company via a telephone line. 

The wind farm is expected to have an operational life of 20-25 years. After this time, the development can either be refurbished to continue generation or decommissioned in order to return the site to its previous state.

A turbine technician visits the site every 3 months
