Exergy Signs 33 MWe Geothermal Contract with Maren in Türkiye Exergy International has signed a new contract with Maren Maraş Elektrik Üretim A.Ş. to supply the 33 MWe Mehmet Ege geothermal power plant in Germencik, in Türkiye’s Aydın province. The project will use Exergy’s Organic Rankine Cycle technology and include the company’s largest Radial Outflow Turbine supplied to date. Expected to enter operation in the second half of 2027, the plant will provide renewable baseload electricity from a geothermal resource with an estimated temperature of approximately 160°C. The agreement represents another major step in Exergy’s long-standing relationship with Maren and reinforces Türkiye’s position as one of the world’s most active geothermal markets. A Major Geothermal Investment in Aydın The Mehmet Ege geothermal power plant will be located in Germencik, a district within Aydın that has become a major centre for geothermal development.

Eavor Technologies achieved a significant breakthrough in December 2025 when its flagship closed‑loop geothermal project in Geretsried, Germany, began delivering electricity to the grid. By: Robert Buluma The Canadian startup had completed the first of four planned underground loops and intended to start construction on the second loop in early 2026. That timeline has now been revised. The company encountered substantial engineering difficulties while drilling the initial wells, including borehole instability, slow penetration rates, equipment failures, and cement‑casing issues that allowed fluid to leak between parallel drilling rigs. Although Eavor resolved those problems, the setbacks increased both time and cost. As a result, the firm is now looking for new project partners and investors to help complete the next phase. The Geretsried site, located south of Munich, was chosen precisely because it is geologically challenging. Previous conventional geothermal attemp...
