In a monumental development for the Mediterranean and Middle Eastern renewable energy landscape, the Nordex Group has finalized a contract with Türkerler Holding to supply, install, and service a massive 525MW wind energy project. The venture, known as the YEKA-5 R25 Sivas wind project, stands as a testament to the accelerating energy transition within Türkiye and reinforces the German-based turbine manufacturer’s dominant position in the local market.
The project represents more than just a capital investment; it serves as a cornerstone of Türkiye’s ambitious renewable energy targets, leveraging advanced engineering to harness the consistent wind resources found in the Sivas region.
Main Facts: The Scope of the YEKA-5 R25 Project
The agreement between Nordex Group and Türkerler Holding marks one of the largest single-order turbine transactions in the history of the Turkish wind sector. At its core, the project entails the deployment of 72 units of the highly efficient N175/6.X wind turbines.
Technical Specifications and Site Dynamics
Each of these Delta4000 series turbines will be mounted on towers with a hub height of 108 meters, a configuration specifically selected to maximize energy capture in the Sivas region. Nordex engineers have conducted extensive wind resource assessments, determining that the consistent, steady wind profiles of the Sivas site are perfectly matched to the operational parameters of the N175/6.X platform.
Operational Longevity
Sustainability and reliability are central to this partnership. The contract includes an initial ten-year premium service agreement, ensuring that Nordex technicians will manage maintenance and operational efficiency. Crucially, the agreement contains a flexible extension clause, allowing the service period to be stretched to a total of 25 years. This long-term commitment guarantees that the infrastructure will remain at peak performance throughout its operational lifecycle, significantly reducing the levelized cost of energy (LCOE) for the project developers.
Chronology: From Planning to Power Generation
The project’s roadmap is meticulously structured to align with Türkiye’s broader energy grid expansion goals. While the ink is dry on the contract, the logistical journey to completion involves several critical phases.
- Project Inception and Procurement: Following successful outcomes in previous YEKA (Renewable Energy Resource Zone) tenders, Türkerler Holding selected Nordex Group as their strategic partner, citing the manufacturer’s proven local supply chain and technology reliability.
- Manufacturing Phase (2026–2027): The supply chain for this project is anchored by Nordex’s recently inaugurated rotor blade manufacturing plant in Menemen, İzmir. Opened in May 2026, this facility was specifically designed to handle the increased demand for high-efficiency onshore technology. The manufacturing of the 72 turbine units will be synchronized with the project’s installation schedule.
- Installation Commencement (Q3 2027): The site preparation at Sivas is slated for completion in time for the first turbine installation, which is scheduled to commence in the third quarter of 2027.
- Operational Horizon: Once fully commissioned, the 525MW facility will contribute significantly to the Turkish national grid, providing clean electricity to thousands of households and industries, thereby reducing the country’s reliance on imported fossil fuels.
Supporting Data: Nordex’s Regional Dominance
The Nordex Group’s success in securing the Sivas project is not an isolated incident but rather the result of a long-term strategy focused on localization and technical superiority.
Market Share and Regional Footprint
Nordex currently commands a 34% market share in Türkiye, a figure that is set to climb following the successful completion of the YEKA-5 R25 project. This market dominance is supported by a robust local presence that minimizes logistical costs and creates significant employment opportunities within the Turkish engineering and manufacturing sectors.
A History of Scale
Since its founding in 1985, the Nordex Group has cemented its reputation as a global leader in wind energy, having commissioned more than 64GW of wind power capacity across more than 40 countries. The N175/6.X turbine, which features heavily in the Sivas deal, is part of the Delta4000 platform, a series renowned for its flexibility, allowing it to be configured for various site conditions—from low-wind to high-wind environments—without compromising on mechanical integrity.
The Role of Local Manufacturing
The May 2026 launch of the Menemen blade plant is a strategic masterstroke. By producing critical components on Turkish soil, Nordex has insulated its projects from the volatility of international shipping and supply chain disruptions. This localized approach has fostered deep trust with major players like Türkerler Holding, who view Nordex as a stable, long-term partner rather than a transactional vendor.
Official Responses: Strengthening the Partnership
The announcement has been met with enthusiasm from the leadership teams of both organizations, who emphasized the collaborative nature of the deal.
Ender Özatay, Vice-President of the Nordex Group for the Türkiye and Middle East region, expressed his gratitude for the partnership:
"Türkerler Holding has placed its trust in the Nordex Group and has chosen us as its partner for the biggest single turbine deal in the Turkish wind energy market, and we sincerely thank the company for that. We are delighted to support Türkerler Holding’s ambitious growth in renewable energy. Following our success in earlier YEKA projects, this order once again demonstrates the competitiveness of our N175/6.X technology, our strong local supply chain, and the confidence customers place in our team and technology."
Türkerler Holding, known as a repeat customer for the Nordex Group, has consistently prioritized technical efficiency in their renewable energy portfolio. By opting for the premium service package, the company is signaling its commitment to long-term asset management and operational excellence.
Implications: The Future of Turkish Wind Energy
The Sivas 525MW project holds profound implications for the Turkish energy sector, the environment, and the broader global push toward decarbonization.
Economic Implications
By adding 525MW of capacity to the national grid, the project helps stabilize energy prices. Wind energy, once commissioned, provides a hedge against the price volatility inherent in global natural gas and coal markets. Furthermore, the reliance on local manufacturing facilities in Menemen stimulates the local economy, creating high-skilled jobs and fostering a culture of technological innovation in the Aegean region.
Environmental Impact
The transition to renewable energy is a non-negotiable priority for Türkiye. The Sivas wind project will play a direct role in lowering the carbon intensity of the national electricity mix. By displacing older, emission-heavy power generation methods, this project will help Türkiye meet its climate commitments under international agreements, contributing to a substantial reduction in annual CO2 emissions.
Strategic Energy Independence
For Türkiye, energy security is a matter of national interest. The expansion of wind power—a domestic resource—reduces the country’s dependency on imported hydrocarbons. As projects like YEKA-5 R25 scale up, they contribute to a more resilient, diversified energy architecture capable of supporting Türkiye’s growing industrial base.
Setting a New Benchmark
The scale of this project—525MW in a single development—sets a new benchmark for utility-scale wind power in the region. It signals to investors and international energy developers that the Turkish wind market is mature, stable, and ready for high-capacity, sophisticated infrastructure projects. As the industry moves toward larger, more efficient turbines, the success of the N175/6.X series in Sivas will likely serve as a blueprint for future tenders across the Middle East and Central Asia.
In conclusion, the partnership between Nordex Group and Türkerler Holding represents a synergy of advanced German engineering and ambitious Turkish industrial vision. As the installation phase approaches in 2027, the project stands as a beacon of progress, illustrating how targeted investment in wind technology can yield substantial rewards for the environment, the economy, and the national grid.
