It seems that the amount of time spent generating electricity is quite short with payments made to ‘owners’ when the unit does not make electricity. Apparently during stormy weather the units are ‘feathered’ so as not to cause damage and also no one wants a blade sailing through their property. Figures bandied around vary but when the turbine isn’t turning the owners are compensated to the tune of “Millions” of whatever currency is used in whatever part of the world. Some small farms become too expensive to repair and are just left as is. The cost of maintenance at offshore farms must be horrendous during even moderate weather.
