Yinson Renewables has acquired the rights to Mt Cass Wind Farm from MainPower New Zealand Limited, marking the company's first wind farm project under construction and its inaugural venture in New Zealand. The acquisition was announced on December 18, 2025.

Project Timeline and Capacity

Construction activities for the Mt Cass Wind Farm are expected to commence in early 2026, with the project entering operations in 2028. The wind farm is designed for a total installed capacity of 94.6 MW.

Once operational, Mt Cass is expected to generate over 300 GWh of electricity annually, sufficient to supply approximately 40,000 households. This generation capacity represents a significant addition to New Zealand's renewable energy infrastructure.

Strategic Significance

The Mt Cass Wind Farm holds important strategic value for New Zealand's energy sector, as it will add much-needed generation capacity to the upper South Island. The project is positioned to help New Zealand meet its decarbonisation goals as part of the country's broader energy transition efforts.

For Yinson Renewables, this acquisition represents a significant expansion of the company's footprint in New Zealand. The project marks a notable milestone as Yinson Renewables becomes the first foreign-owned independent power producer to own and construct a wind farm in the country.
