YEO Energy Investments, a subsidiary of YEO Technology that carries out discrete energy and energy storage investments, continues its new term planning management with the CALL Energy brand. CALL Energy aims to reach a renewable energy portfolio of over 1,000 MW in 4 continents and over 10 countries.
CALL Energy’s renewable energy investments, which will be implemented by taking into account resource and geographical diversity, will make a difference thanks to the asset management designed with the digital integration of energy storage systems.
YEO Energy Investments continues its path with the CALL Energy brand, a global energy platform in line with its new era vision. CALL Energy, with a strong renewable energy portfolio, aims to stand out as a next-generation energy platform.
Target: 1,000 MW Installed Capacity
olunay Yıldız, Chairman of YEO Technology, and Sacit Akbaş, CEO of CALL Energy, shared insights into the transformation and goals of CALL Energy for the upcoming period. The company is accelerating projects both in Türkiye and abroad. In Türkiye, CALL Energy holds pre-licenses for nine storage-integrated solar power plants, totaling 346 MWe. Two of these projects are currently getting generation licenses and are scheduled to start construction in 2026. In addition, four hydropower plants with a total installed capacity of 32 MWe on the Aras River are nearing completion of the permitting process. Globally, CALL Energy operates solar plants in Romania and Italy with a combined capacity of 32.6 MWp. With the addition of two new projects under construction—planned to be operational by the end of this year—CALL Energy is on track to expand its installed capacity in Romania to over 190 MWp.
CALL Energy continues to develop a project portfolio of over 1,500 MW across 4 continents and 10 countries. With the projects moving into the investment phase, the company’s operational installed capacity is expected to surpass 1,000 MW by 2030.
‘Just investing is not enough anymore’
Appointed as CEO of CALL Energy at the end of May, industry veteran Sacit Akbaş stated: “Today, it is no longer sufficient just to invest. Changing climate conditions, declining incentive mechanisms, and fluctuating energy prices push us toward different strategies.” He continued: “At CALL Energy, we have set out to be at the forefront of this transformation and to implement our investments with more efficient, integrated, and sustainable models. We must go beyond the traditional investment mindset and operate our plants in the most efficient way by integrating storage systems. That is why we are continuing our global growth not just as an investment company, but also as an energy platform that prioritizes asset management.”
The Energy Sector is Transforming
Akbaş highlighted that the energy sector in Türkiye is growing through renewable energy investments. While renewable sources now make up 60% of Türkiye’s total installed capacity, more than 95% of the new installations in 2024 were in this sector. CALL Energy aims to contribute strongly to this transformation with its storage integration, on-site production solutions, and asset management models.
Tolunay Yıldız, Chairman of YEO Technology, stated that their target is to reach 1 GW of capacity in renewable energy by 2030 and added: “CALL Energy under the YEO umbrella is progressing toward becoming a global player with its ability to operate in various geographies. As YEO Technology, we now lead energy transformation not only in Türkiye but on a global scale. The projects we implement, our engineering expertise, and our competence in the renewable field prove this. We will continue to sign large-scale projects especially in European markets. Our goal is to make the world a cleaner place through sustainable energy investments and represent Türkiye on the global stage.”
YEO Technology, which carries out projects in diverse areas such as advanced energy storage solutions, electric grids, high-voltage substations, renewable power plants, industrial and commercial facilities, and hydrogen systems, has completed over 400 projects in more than 30 countries across 3 continents. With its focus on decarbonization, decentralization, and digitalization, YEO continues to grow with the motto “We Make It Possible.”
