Harmony Energy New Zealand, in a joint venture with Igneo Infrastructure Partners, has energized the 202MWp Tauhei solar photovoltaic plant near Te Aroha in the Waikato region, according to a report from PV Tech.
The facility will now enter a testing and commissioning phase lasting several months, with full commercial operations expected between September and October 2026. Once fully operational, Tauhei is projected to generate roughly 280GWh of renewable electricity annually. All output from the first decade of operation has been sold to gentailer Meridian Energy under a power purchase agreement, while a separate contract covers generation during the commissioning period.
Harmony Energy New Zealand managing director Garth Elmes commented that reaching this milestone was exciting, describing the Tauhei Solar Farm as a significant project that will strengthen the supply of affordable renewable energy. He expressed pride in contributing to New Zealand’s domestic energy security amid global uncertainty and rising cost-of-living pressures.
The plant occupies 182 hectares of former farmland, transitioning from dairy to sheep farming in an agrivoltaics setup where solar panels provide shade for livestock and help retain soil moisture during dry spells. As part of environmental commitments, approximately 100,000 native plants have been installed along boundaries, riparian margins, and biodiversity corridors.
During the 18-month construction phase, the project supported a peak workforce of about 350 full-time equivalent construction staff, with over 1,000 workers inducted on site. The project originally began as a joint venture between Harmony Energy and First Renewables, a subsidiary of New Zealand energy group Clarus. Harmony Energy announced its plan to co-develop the 202MWp plant with Clarus in January 2024, at the time describing it as one of the most advanced large-scale solar projects in New Zealand’s pipeline.
The project received fast-track consent under New Zealand’s Covid-19 Recovery (Fast-Track Consenting) Act in September 2022, which allowed a streamlined approvals process due to the project’s scale and its role in meeting the country’s renewable energy targets. Financial close was reached in January 2025, supported by a syndicated debt facility from ANZ, ASB, BNZ, and MUFG Bank. Construction began shortly thereafter, with Spanish infrastructure contractor Elecnor New Zealand appointed as the EPC contractor. Igneo Infrastructure Partners joined as a joint venture partner alongside Harmony Energy, replacing the original Clarus/First Renewables structure, at some point before the energization announcement.
Tauhei now surpasses the 63MWp Lauriston solar PV plant, which was opened by Genesis Energy and FRV Australia and had been claimed as New Zealand’s largest solar farm when it began operations in April 2025. New Zealand’s electricity system relies predominantly on hydropower, which historically limited the urgency for large-scale solar development. However, dry-year hydro risk and growing demand from electrification have sharpened commercial interest in diversifying the generation mix.
In 2024, PV Tech reported on a New Zealand energy crisis triggered by wholesale pricing spikes due to gas shortages and low rainfall affecting hydroelectric resources. That crisis underscored the need for diversification in the energy mix, creating opportunities for solar PV expansion. Beyond Tauhei, Harmony has three additional developments totaling approximately 300MW that were lodged with the Environmental Protection Authority under fast-track legislation at the end of 2023.
