OYAK Purchases 100% Stake in ISKEN Enerji

ISKEN alone accounts for approximately 3% of Türkiye's total electricity production.

Following the agreement reached in July 2025, the official signing ceremony took place in Madrid with the participation of Yüksel Yılmaz, Chairman of the Board of OYAK Energy Companies, and Uğur Doğan, Chairman of the Board of ISKEN Enerji. With the transfer of shares, not only ISKEN but also the company responsible for port and handling operations came fully under OYAK’s control.

OYAK General Manager Murat Yalçıntaş emphasized that energy security is not merely an investment area, but a responsibility undertaken for the future of Türkiye:“ISKEN plays a critical role in ensuring the security of our country’s energy supply by meeting approximately 3% of Türkiye’s total electricity production on its own. Our acquisition of a 51% stake in Steag Power GmbH, securing full control over ISKEN, is a clear reflection of our perspective on this matter. This strategic move is a strong indication of our commitment not only to today’s energy needs but also to securing the energy of the future.”

Yalçıntaş stated that OYAK’s energy investments are directly aligned with Türkiye’s sustainable development goals, and continued:“Energy is a fundamental pillar of economic independence and the sustainability of industry. In this field, our goal is not only to increase our production capacity, but also to build a long term value chain that supports environmental and technological transformation. We prioritize responding to Türkiye’s growing energy demand with reliable, efficient, and environmentally conscious solutions.”

In a statement from OYAK, it was emphasized that the conclusion of the partnership with Steag Power GmbH, following a successful collaboration of over 20 years, has made significant contributions to the energy sector. The statement was including:“During our partnership with Steag, we shared valuable knowledge and experience in the energy field. Steag’s professional approach and collaborative attitude were key elements of our joint success. On this occasion, we would like to extend our gratitude to the management and all employees of Steag Power GmbH, and we wish them continued success in their future endeavors.”
