Tosyalı Holding has announced a major renewable energy initiative, signing an agreement with GE Vernova and Inogen to develop one of the world’s largest self-consumption Solar Power Plant (SPP) projects. The first phase of the project, with a capacity of 120 MWp, will use Tosyalı’s locally manufactured N-Type Topcon 725 Wp panels, marketed under the Tosyalı V-Solar brand. The project is expected to reach a total capacity of 1.2 GW by its completion in 2027.
Advancing Green Steel through Renewable Energy
A global leader in green steel production, Tosyalı boasts an annual crude steel production capacity of 15 million tonnes. The company continues to prioritise eco-efficient practices, integrating cutting-edge technology, artificial intelligence, and clean energy solutions.
Tosyalı’s previous achievement of installing 235 MW of rooftop solar capacity—the largest globally—has already placed the company at the forefront of renewable energy in industry. Now, the new 1.2 GW self-consumption project takes this commitment further, with the first phase targeted to become operational in 2025.
At the World Economic Forum 2025 in Davos, Chairman Fuat Tosyalı highlighted the significance of this development: “With this investment, Tosyalı will generate approximately 50% of its self-consumption from solar energy.”
A Milestone for Sustainability
At Davos, Fuat Tosyalı shared the broader vision for the project: “We continue to invest in advanced clean energy technologies under our vision of ‘Tosyalı for a sustainable life.’ As part of this vision, we have taken the first step toward one of the world’s largest self-consumption SPP projects with a capacity of 1,2 GW by initiating the first project in Osmaniye. We are happy to collaborate with GE Vernova, one of the world’s leading companies in this field, and Inogen, Turkey’s leading EPC contractor. We will produce our solar panels in Osmaniye. Starting with the first project, these panels will be deployed across SPP sites in eight provinces. By doing so, we aim to meet approximately 50% of our energy needs from solar energy. This will make us stronger and more independent in energy usage and further strengthen our position among the world’s leading green steel producers.”
The project, among the largest globally in its category, will be completed in three stages. Construction for the first 120 MW phase has already begun in Osmaniye.
Strategic Partnerships for a Greener Future
Ali Murat Soydan, Chairman of Inogen Group, expressed pride in being part of Tosyalı’s initiative: “We are happy to be involved in this pioneering project of Tosyalı, a symbol of green transformation in the world and our country. When all the Tosyalı projects are completed, we will strengthen our position as the green transformation leader in our country working with GE Vernova. In these projects, which will be carried out in 10 different provinces with more than 2000 employees, we plan to go through an efficient and fast installation process and commission all the power plants as soon as possible, with the support of our global partners.”
Ed Torres, Business Leader for GE Vernova’s Power Conversion & Storage division, stated: “Along with Inogen, we are proud to support Tosyalı’s ambitious goal of developing one of the world’s largest self-consumption solar power projects. By supplying our advanced solar technology, providing design and engineering services, and facilitating ECA financing, we aim to help Tosyalı achieve greater energy independence and accelerate the transition toward a more resilient energy future.”
