Mahinerangi Wind Farm is located west of Dunedin near Lake Mahinerangi, in the South Island of New Zealand.

Project Details

The Mahinerangi wind farm site was first identified during construction of Trustpower's Deep Stream hydro asset in the same location.  At that time it became clear that the wind which was hampering progress on the construction of Deep Stream could be useful, especially as Trustpower owned a large portion of the land required for the wind farm.

The wind farm development was split into 2 stages in order to utilise, the existing 33kV transmission line to the Deep Stream hydro asset, avoiding the requirement for transmission infrastructure to be included in the investment.

“By connecting Stage 1 through the existing 33kV infrastructure, water is stored when the wind is blowing, and water is used for generation at time of low wind - proving the symbiotic relationship between the two forms of renewable generation.”

This was completed in 2011 and consists of twelve Vestas V90 turbines, each producing 3MW, for a total capacity of 36 MW. 

Estimated annual production is 101 GWh. Other infrastructure includes meteorological masts, a 33kV interconnection network, a small switch yard including voltage support equipment, about 6km of access tracks and maintenance facilities in an existing farm house. 

Less than 2% of the site’s land area is used by the wind farm, which is why the land remain a productive dry stock farm.
