The Tararua Wind Farm stands on 700 hectares of private farmland in the Tararua Ranges, in the lower North Island of New Zealand and all three stages combine to make New Zealand's largest wind farm.
- Maximum capacity
- 68 MW
- Annual output
- 245 GWh
- Stage 1: 1999, Stage 2: 2004
- Tararua Ranges, Manawatu
- Circa NZ$105m in two stages
Built over two stages, without government subsidy or incentives, stages 1 and 2 have a total of 103 Vestas V47-660 kW wind turbines, on lattice towers with a hub height of 40m.
Stage 1 was completed in December 1999, making it the largest wind farm in the southern hemisphere at the time. This was also when Tilt Renewables (Trustpower) took ownership, entering the fledgling wind industry for the first time.
Stage 2 was the first wind farm construction project executed by the Tilt Renewables team, adding 55 turbines to the existing 48 from stage 1. The project was successfully delivered ahead of time and budget by the team that currently makes up the Tilt Renewables executive.
For many years this site was the best performing commercial wind farm in the world and the original turbines have already generated more than twice the designed production volumes.
The turbines still achieve reliability similar to new turbines, a testament to the asset management program delivered by Vestas, as maintenance partner to Tilt Renewables for more than 17 years.
