Trustpower has a 10-year consent to build a 48 turbine 130MW wind farm in South Taranaki. The consent includes a 13 kilometre 10kV transmission line from the site to Transpower’s Waverley substation and was issued in July 2017.
The wind farm was expected to cost $325m to build and generate 490GWh of electricity a year which, based on average residential consumption, would produce the same amount of electricity as used by over 65,000 homes.
The wind farm is in a great location to provide renewable electricity to meet growing demand and displace existing thermal generation with its high level of carbon emissions. The wind farm could avoid 337,400 tonnes of C02 per year if this electricity were to be generated from a coal-fired plant or 196,800 tonnes in avoided gas fire generation.
In 2016 Trustpower received final court approval for the demerger and listing of its Australian and New Zealand wind businesses. Tilt Renewables is now responsible for the wind farms consent.
Commencement of construction
Genesis and Tilt Renewables announced on 17 October 2018 they intend to partner in the development of the Waipipi (formerly Waverley) Wind Farm. They have established a strategic relationship and agreed proposed terms and conditions for a long-term power purchase and services agreement.
The Waipipi Wind Farm will be owned and operated by Tilt Renewables and the investment decision to commence construction was announced in August 2019 with the electricity to be sold to Genesis Energy under a 20-year offtake agreement.
An event to celebrate the commencement of construction was held in November 2019.
The wind farm will have a total capacity of 133MW and will consist of 31 4.3ME Siemens Gamesa turbines each with a 130m rotor diameter. The total expected cost of the project is $276 million.
Once operational, the average annual generation will be 455GWh. The electricity generated will meet the annual electricity needs of approximately 64,000 average homes or over 200,000 electric vehicles.
The wind farm could avoid 443,000 tonnes of C02 per year if this electricity were to be generated from a coal-fired plant or 207,000 tonnes in avoided gas fired generation.
About this site
The wind farm is located approximately 6km south-east of Patea and 7km south-west of Waverley, in South Taranaki.
There was concern about the turbine’s effect on seabird populations in the area. The effect has been mitigated by filling in three ponds and enhancing some water bodies, wetlands and dunes outside the wind farm’s footprint to improve bird habitats outside the area.
