TOPP2 geothermal power plant in Kawerau, New Zealand
The TOPP2 project, a binary power plant with facilities supplied by Ormat Technologies, represents Eastland Generation’s largest geothermal initiative to date. It increases the company’s operating capacity to 118 MW. This marks the first major project completed since Obayashi Corporation acquired a 50% stake in Eastland Generation. Alice Pettigrew, CEO of Eastland Generation, stated: “When TOPP2 is fully operational, Eastland Generation will have achieved the next phase of our growth strategy.”
The project involves a collaboration with Ngāti Tūwharetoa Geothermal Assets Limited (NTGA), which manages the steam field and wells, ensuring a long-term geothermal energy supply for the power station. This partnership strengthens the project’s operational foundation, leveraging local expertise to support sustainable energy production in the Kawerau geothermal field.
Eastland Generation operates three geothermal power plants in the Bay of Plenty’s Kawerau region: Te Ahi o Maui (26 MW), Geothermal Developments Ltd (9 MW), and TOPP1 (24 MW). Additionally, the company manages a 5-MW hydropower station near Wairoa and a 5-MW utility-scale solar farm in Tairāwhiti. The TOPP2 plant enhances the company’s portfolio, contributing to New Zealand’s renewable energy goals by providing clean, reliable power.
The tender for TOPP2’s power offtake reflects Eastland Generation’s commitment to expanding its renewable energy footprint while fostering partnerships to ensure efficient and sustainable operations. The project positions Kawerau as a key hub for geothermal energy, supporting both regional energy needs and environmental sustainability.
