A hybrid wind turbine assembly and method capable of providing a total firm power output. There is a wind power section which delivers non-firm power from the wind turbine to a generator section. Then there is also an auxiliary power section which is capable of providing firm power to the same generator section. This can operate in three operating modes, namely an only wind power mode, an only auxiliary power mode, and a combined wind power and auxiliary power mode.
