Mercury has flicked the switch on Turitea - New Zealand鈥檚 biggest wind farm.

Energy Minister Megan Woods today cut the ribbon at a 鈥渟witch-on鈥 ceremony on the farm, in the Tararua Ranges.

Mercury chief executive Vince Hawksworth said the energy sector is key to New Zealand鈥檚 low-emissions future and that had been reflected in the high levels of investment in the sector.

Representatives of mana whenua Rangit膩ne o Manawat奴, local government and community, and key contractors attended the opening event, three and a half years after the ground-breaking in October 2019.

聽鈥淭uritea [near Palmerston North] is a site of exceptional wind quality, and our teams rose to the challenge of constructing 60 turbines and transmission infrastructure on its slopes,鈥 Hawksworth said.

鈥淢ercury takes a long-term view when it comes to significant investment in new electricity generation, and this includes our commitment to custodianship of this site,鈥 he said.

The $465 million project was announced in 2019, the same year the Government passed the Zero Carbon Act that set up a framework to achieve the aims of the 2015 Paris Agreement, including a target to reduce emissions of all greenhouse gases (except biogenic methane) to net zero by 2050.

Turitea鈥檚 33 northern turbines have been generating power for the grid since December 2021 and the southern 27 turbines are coming on-stream, with full operation scheduled for June.

Mercury鈥檚 next project will be the 43MW Kaiwera Downs Stage I, currently under construction near Gore, with commissioning scheduled for late this year.

The company has a pipeline of further projects that is almost equivalent in size to Mercury鈥檚 existing generation portfolio with over 8000GWh either in construction, consented or in the consenting process.

Turitea has the capacity to produce 840GWh hours a year - enough to power 120,000 households.

It comprises 60 turbines, with each measuring 125 metres from ground to blade tip.

Each blade is 55 metres long.
