The 176MW Harapanaki wind farm is proposed to be built by Meridian Energy, New Zealand’s government-owned electricity generator and retailer, in Hawke’s Bay, New Zealand. Upon completion in 2024, it will be the second largest wind farm in the country. The clean energy generated by wind power facilities will be enough to power more than 70,000 homes a year. The construction phase will last nearly three years and is expected to generate around 260 jobs. The wind farm development is anticipated to involve an investment of NZD395 million ($ 282 million), which will be pledged as collateral from a bank facility. Investing in the Harapanaki wind farm will enhance the New Zealand Government’s ability to take action on climate change and the economy’s transition to greener sources of energy. Meridian operates five other wind farms in New Zealand, including Te Uku, West Wind, Mill Creek , Te Āpiti and White Hill. The location of the Harapanaki wind power plant A wind farm will be constructed in the Maungaharuru Mountains in Hastings District on Hawke’s Bay, about 35 km northwest of Napier. The project is expected to cover 9 km in reach, covering 1,235ha of land. The Whirinakito-Wairakei 220kV dual circuit transmission line belonging to the state-owned company Transpower New Zealand crosses the corner of the project site. The site is strategically located above the transmission boundary south of Wairakei. Harapanaki wind power plant timeline Meridian Energy is licensed to build and operate a wind farm in Hawkes Bay. Thearapaki wind farm combined resource approvals granted to two separate wind farms at adjacent sites in 2005. The company obtained a sourcing permit for the Hawkes Bay wind power plant from Hawke’s Bay Wind Farm Ltd in 2010 and a permit for the neighboring Titiokura wind farm from Unison Networks. After obtaining approval, Meridian focused on site research, studying wind patterns and geography to identify the best layout for the project. Turbine details The Harapanaki wind farm will feature a 4.3MW rated SWT-DD-120 wind turbine from Siemens Gamesa. Each turbine will have a rotor diameter of 120m and a length of 145m, from base to finish. The wind power plant is expected to produce around 542GWh of clean energy per year. Construction details Wind farm project development is expected to start in 2021, with final commissioning anticipated in mid-2024. About 23 km of roads are expected to be built, along with 232 km of cable. The construction work will include approximately 18,000 m³ of concrete and 860,000 m³ of cutting. Advanced European wind power generation technology will be applied to set new benchmarks for sustainable construction practices and turbine efficiency. The design review reduces the amount of concrete and steel that will be used in construction, reducing the project’s carbon footprint by more than 30%. Suppliers and contractors involved Siemens Gamesa was awarded a contract to supply 41 SWT-DD-120 4.3MW turbines. The contract also covers the installation and maintenance of the wind turbines. Meridian Energy contracted Transpower to supply, install and commission a 220kV substation and grid connection for the wind power plant. Hyosung was selected for the supply, installation and commissioning of the 220 / 33kV transformer while the Italian company Prysmian will supply the 33kV reticulated cable for the project. Unison Contracting Services received a contract to provide electrical services for the substation, wiring connections and installation of 33kV switchgear. The Hick Bros Spartan Joint Venture is responsible for the construction of all roads, hardstand cranes and turbine foundations.
