TrustPower to start Mahinerangi Wind Farm
14 May 2010
TrustPower’s board of directors has approved a first stage development of the Mahinerangi Wind Farm, with construction due to start in September this year.
TrustPower has resource consent for a 200 MW wind farm at the Mahinerangi site, which is adjacent to the four-station Waipori Hydro Generation Scheme fed by Lake Mahinerangi.
Stage One of the wind farm will be a 36 MW development, which will include the installation of twelve 3MW Vestas V90 wind turbines. The long term expected annual output from the wind farm is forecast to be 105 GWh per annum, which is enough power to supply approximately 13,000 Dunedin homes.
Construction of the wind farm is due to start in September 2010 and be completed in April 2011, with the first power expected to be produced in February 2011 and the wind farm completed and fully commissioned in May 2011. The power from the Mahinerangi Wind Farm will feed directly into an existing line, used by the Waipori hydro scheme, which is connected to Dunedin’s Halfway Bush substation, and then through to the local Aurora Network.
TrustPower Chief Executive Vince Hawksworth says TrustPower is delighted to be building its first South Island wind farm, which will add to TrustPower’s existing portfolio of wind farms in the North Island and South Australia, along with its 17 South Island hydro generation schemes.
“The Mahinerangi Wind Farm will allow TrustPower to make the best use of both wind and hydro resources, allowing us to get even better efficiency out of our Waipori hydro scheme. The new Wind Farm will also improve security of supply for Dunedin and free up electricity currently being imported into Dunedin from Roxburgh and the Waitaki system for use elsewhere,” says Mr Hawksworth.
The projected capital cost of the project, including capitalised interest, is expected to be around $75 million.
The project will bring around $12 million directly to the local economy and will employ between 20 and 30 people during the construction phase. The civil component of the work will be completed by the Dunedin branch of construction firm Downer NZ.
