Exergy International has signed an agreement with Kocaer Enerji to supply the first phase of the Kocaer-1 geothermal power plant in Aydın Province, Türkiye, with a gross installed capacity of 12.34 MWe.
The project is being developed in the Buharkent and Kuyucak districts as part of Kocaer Enerji’s wider geothermal power and resource exploration programme. It will use a geothermal resource at approximately 135°C to generate renewable electricity.
Exergy will provide the design, engineering, manufacturing and supply of the ORC-based power plant equipment. The facility will use one Exergy Radial Outflow Turbine and an air-cooled condenser, allowing the plant to convert the medium-temperature geothermal resource without using water for condensation.
The turbine and generator will be manufactured in Türkiye at Exergy Türkiye Turbin Enerji Teknolojileri, Exergy’s local manufacturing facility. The company said the use of locally manufactured components could allow the project to qualify for an additional feed-in tariff under Türkiye’s local-content incentive framework, subject to regulatory approvals.
The order marks Exergy’s second geothermal project in Türkiye in just over a week, bringing its total geothermal project portfolio in the country to 538 MWe.
“We are very pleased to welcome Kocaer Enerji as a new customer and to have been selected for this project,” said Luca Pozzoni, deputy CEO of Exergy International.
Kocaer Enerji chairman Hakan Kocaer said geothermal power offered Türkiye a domestic source of baseload renewable generation and that the company intended to build on the Kocaer-1 project as it expands its clean-energy portfolio.
Türkiye had 1,797 MWe of installed geothermal power generation capacity at the end of 2025. Capacity additions have slowed in recent years, following a period of rapid expansion between 2016 and 2021.
Kocaer Enerji is a 99%-owned subsidiary of steel producer Kocaer Çelik and is developing a portfolio focused on renewable and clean energy, including geothermal projects in Aydın.
