Exisiting Wind Turbines Retrofit 

IQwind’s breakthrough variable ratio gearbox technology makes IQgearbox a valuable alternative for retrofitting existing wind turbines when their gearboxes are due for replacement.  The gains in annual energy yield enabled by IQgearbox retrofit translate into significant economic value.

For the Fixed Speed (FS) wind turbines, IQgearbox retrofit provides aerodynamic and control improvements that could increase average annual energy yield by up to 20%.  Total IQwind market for the FS turbines retrofit is at least $10 Billion.

When used to retrofit the Doubly Fed (DF) wind turbines, IQgearbox makes it possible for the generator to be operated in the above-rated power range at high wind speeds, increasing the average annual energy yield by ~8%.  Total IQwind market for DF turbines retrofit is at least $20 Billion.
