Exclusive interview with Exergy : discover the new Gemini dual-flow radial outflow turbine, the first single-unit ORC solution for 30–60 MW geothermal projects, offering up to 30 % lower costs and 99 % availability. By:  Robert Buluma .   An interview with  Luca Pozzoni -  Deputy CEO | Group CFO - Exergy International and the Exergy Team 1. Can you walk us through the key design innovations in your new Gemini turbine and how it differs from previous models? The major innovation of the Gemini turbine lies in the dual-flow configuration: unlike conventional radial outflow turbines which are equipped with a single bladed overhung rotor disk, the Gemini features a double-side bladed rotor disk mounted in a between-bearing configuration. This enables the efficient processing of significantly larger volumes of fluid, leading to higher power output having basically two radial outflow turbines in a single machine with enhanced operational stability and simplified mainte...

Exergy ORC Delivers Two Geothermal Power Plants in Turkey in Record Time: 46 MW Added in Under 13 Months By:  Robert Buluma On November 30, 2025, Exergy International proudly announced the successful commissioning of two new geothermal power plants in Aydın, Turkey: Maren Nezihe Beren 2 (13 MWe) and Emir (33 MWe), totaling 46 MW of new clean electricity capacity. What makes this milestone truly remarkable is the execution speed , both plants were delivered in less than 13 months from contract signing to full commercial operation, setting a new benchmark in the geothermal ORC (Organic Rankine Cycle) industry. Why This Achievement Matters in 2025 In an era where renewable energy projects often face delays of 24–36 months (or longer), completing two binary-cycle geothermal plants totaling 46 MW in under 13 months is nothing short of extraordinary. Turkey already ranks 4th globally in installed geothermal capacity (~1.7 GW as of 2024), and these new plants reinforce the country’s lead...
