Ventus Energy (NZ) Ltd has been actively progressing a number of sites in the upper North Island and currently has three active wind development projects including the Taumatatotara and Kaimai Wind Farm projects.
Taumatatotara is proposed on a well defined ridgeline 10km south of Taharoa in the Waitomo District.   Up to 11 turbines are proposed each with a maximum tip height of up to 172m (subject to consent ammendment). The power output of the turbines will be 4.3MW, giving a total power rating of 47MW.   The expected beginning of construction is late 2021.

Kaimai Wind Farm is proposed on the northern end of the Kaimai Ranges above Paeroa and Te Aroha townships.   24 turbines are proposed with tip heights up to 207m high.   Application documents to Hauraki District Council can be found here:

Ventus Energy Ltd (Dublin) was incorporated in the year 2000 and has been active in wind farm development in County Limerick and Clare. This has resulted in a 6MW Co. Limerick project (Knockastanna) constructed in 2009 using 6 x 1.5MW GE turbines now owned by Scottish and Southern. 

A second development project of 27MW was sold to Brookfield Renewables who have successfully built and commissioned that project with 11 x N90 Nordex turbines.

Two further projects are in development in County Clare totally 30MW.
