Dr. İskender Kökey is an industrialist, entrepreneur and mechanical engineer who has been active in the wind energy sector since 2010. He is the Managing Partner of XGEN Enerji, a manufacturer of mechanical components for wind turbine manufacturers, and a Board Member of the Turkish Wind Energy Association (TÜREB). He holds a PhD on vertical axis wind turbines.
Professional Career
He entered the sector in 2010, immediately after his undergraduate studies, with his first company, IME-World. He initially worked on off-grid renewable energy systems and went on to provide products and services for the measurement and feasibility stages of wind farm sites.
Between 2013 and 2017, through a partnership with Kintech Engineering, a Spain-based specialist in wind measurement equipment, he managed the company’s operations in Türkiye and the Middle East.
Since 2017, under the XGEN Enerji brand, he has focused on manufacturing the mechanical components required by wind turbine manufacturers and on wind power plant investments.
Education
He completed his bachelor’s, master’s and doctoral studies in Mechanical Engineering at Dokuz Eylül University. During his undergraduate years he received applied physics training in France on photothermal radiometry.
His master’s thesis examined the exergy analysis of a wind power system through a real-world case: Exergy analysis of wind power system: A case study of Izmir, Turkey.
His doctoral research concentrated on vertical axis wind turbines operating in pairs. He manufactured the prototype turbine pair and completed its field experiments under real operating conditions: Performance enhancement of a Darrieus type vertical axis wind turbine pair for different proximities and tip-speed ratios: An experimental analysis. Beyond its own academic output, the work has served as a foundation for many master’s studies.
Industry Associations and Civil Society
He served as Board Member and Secretary General of TÜREB between 2022 and 2025. Since February 2025 he has continued, as a Board Member, to work for the development, promotion and advocacy of the wind energy sector. He has also held administrative positions at the Chamber of Mechanical Engineers, İzmir Branch, and the Energy Industrialists and Business People Association (ENSİA). He has authored numerous academic publications and conference papers on wind energy.
Kökey is married and has one child.
