Ormat Inks New Zealand Deal for World’s Largest Binary Geothermal Plant

💥 Ormat Inks New Zealand Deal for World’s Largest Binary Geothermal Plant 💥

By: Robert Buluma


In a groundbreaking development for geothermal energy, Ormat Technologies has signed a new contract with Contact Energy Ltd. to construct the Tehuka 3 geothermal power plant in New Zealand. This marks Ormat’s 16th geothermal power plant in the country and solidifies New Zealand's growing reputation as a global geothermal powerhouse.

🔋 59 MW of Clean Energy Incoming

Once completed, Tehuka 3 will generate 59 megawatts (MW) of renewable energy—enough to power thousands of homes and industries with clean electricity. Notably, Tehuka 3 is set to become the largest single geothermal binary unit operational plant in the world, representing a new milestone in binary cycle technology.

🌋 Built on Trust, Powered by Tauhara

This contract marks the third collaboration between Ormat and Contact Energy, underscoring a trusted partnership. The Tehuka 3 plant will be located near the existing Tehuka 1 & 2 plants and will utilize the rich geothermal resources of the Tauhara geothermal field, a region known for its vast underground energy reserves.

💨 Advanced Air-Cooled Technology

As part of the agreement, Ormat will supply its air-cooled Ormat Energy Converters, which offer enhanced efficiency and minimal water usage—perfect for sustainable power generation in regions with limited water resources.

💼 Corporate Commitment

Doron Blachar, CEO of Ormat Technologies, emphasized the deal’s strategic importance:

 “The signing of these two contracts increases our product segment backlog and provides a significant contribution to our expected product segment revenues and margins.”

🎉 A Win for Clean Energy

This achievement is a testament to the dedication and collaboration between Contact Energy and Ormat’s teams who worked tirelessly to finalize this game-changing agreement.

Cornwall’s Geothermal Gamble: Council Delays Decision on Slaughterbridge Power Plant

Cornwall’s Geothermal Gamble: Delay Sparks Debate in Slaughterbridge Published: 22 August 2025 By:  Robert Buluma Cornwall at a Crossroads: Energy Opportunity or Environmental Risk? Slaughterbridge, Cornwall – A decision that could have marked a major leap toward renewable energy in Cornwall has been put on pause. Cornwall Council has deferred its judgment on a proposal by Geothermal Engineering Ltd to drill into the hot rocks beneath Slaughterbridge, near Camelford. While the initiative promises clean energy and economic growth, concerns over environmental risks have left the project on hold—for now. What’s on the Table? The heart of the plan, known as Tregath Geothermal , is ambitious: tapping into underground thermal heat to supply about 4.9 MW of renewable baseload electricity to the National Grid. Supporters say it would reduce Cornwall’s reliance on fossil fuels, create jobs, and inject roughly £2 million into the local economy. Sound appealing, right? Fear Benea...
