Our technology

Wind-generated, cleaner power

Through the rotation of blades, wind turbines convert kinetic energy from the wind into mechanical energy, which then drive a generator to produce electricity.

As the wind blows, it spins the turbine blades, activating the generator and creating electricity.

How our turbines work:

Blades

Blades

The blades are 58.6m in length and when connected to the rotor hub give a diameter of 120m. The larger turbine size increases the power output and has allowed the number of turbines to be reduced from 26 to 22, as originally consented for.

Electricity

Electricity

The wind turbines will generate electricity up to 122km/h and withstand gusts up to 350km/h.  

Power Output

Power Output

Each turbine is rated at 4.3 MW, giving the wind farm a maximum power output of 94.6 MW.

Mt Cass Wind Farm will be installing 22 Siemens Gamesa SWT-DD-120 wind turbines, the same model as those installed at Harapaki Wind Farm in Hawkes Bay.  These turbines use direct-drive technology which avoids the need for a large oil filled gearbox.
