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. 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.

Details about stage 1
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 switch yard including voltage support equipment, 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.
