Nordex will supply 72 turbines to Türkerler Holding for the 525MW Yeka-5 R25 project in Sivas, the largest wind farm under development in Turkey, with installation starting in 2027.
Nordex has won an order to supply turbines for a 525MW wind farm in central Turkey, the largest such project now under development in the country. The German manufacturer calls it the biggest single turbine contract it has signed in the Turkish market.
The buyer is Türkerler Holding, a Turkish conglomerate active in construction, real estate development, healthcare and renewable energy. It won a power deal for the site in Turkey’s fifth renewable energy auction round last year. Installation of the machines starts in the third quarter of 2027.
Turbine specification and service terms
Nordex will deliver 72 N175/6.X machines with hub heights of 108 metres at the Yeka-5 R25 Sivas wind farm. Rotors of that size sit at the upper end of the company’s onshore range, so each unit captures more energy at moderate wind speeds. Fewer, larger turbines also cut the number of foundations, crane moves and access tracks a developer has to fund.
The contract runs well beyond supply. Nordex will install the turbines and then maintain them under a ten-year service agreement. That deal can be extended to 25 years in total, which ties the manufacturer to the site for most of its working life. Service income has become the steadier half of the turbine business, because it doesn’t swing with auction cycles the way equipment sales do.
How the auction shaped the order
Turkey allocates large volumes of renewable capacity through its Yeka tenders, which bundle land, grid access and a guaranteed power price into a single award. Sivas came out of the fifth round. Developers therefore know their revenue line before they place an equipment order, and that certainty makes financing a project of this size considerably easier.
Ender Özatay, vice president of the Turkey and Middle East region at Nordex, described the contract as the “biggest single turbine deal in the Turkish wind energy market”. Scale of that kind is unusual for onshore work. Most Turkish wind farms have been built in tranches of a few dozen megawatts, so a 525MW award concentrated at one inland site changes the shape of the pipeline.
Nordex’s position in the Turkish market
The company has already supplied turbines to 3.8GW of operational Turkish wind farms, with a further 1.2GW due, according to Windpower Intelligence, the research and data division of Windpower Monthly. Sivas adds more than half a gigawatt on top of that. Turkey has consequently become one of the manufacturer’s strongest markets outside western Europe.
That matters commercially. European onshore volumes have been uneven, while permitting delays and grid queues have pushed projects to the right in several markets. Turkey, by contrast, keeps running auctions and keeps awarding land with a connection attached. Manufacturers chasing predictable delivery slots have every reason to defend their share there.
The wait until 2027
Nothing goes up for another year. Civil works, access roads, foundations and grid preparation all have to come first, and a site of this size needs substation and transmission capacity ready before the first nacelle is lifted. Sivas sits inland on high ground, so logistics for 175-metre-class rotors will be demanding.
The long lead time suits Nordex in one respect. It fills a production slot well in advance, with a maintenance contract behind it that could run for a quarter of a century. Still, the gap carries risk. Turbine makers absorb the cost of steel, freight and currency movements between signature and delivery, and margins in the sector remain thin enough that a bad year can erase the benefit of a large win.
For Turkey, the more useful test comes later. Building the country’s largest wind farm on schedule would show that its auction model can deliver at gigawatt-scale ambition, not just at the pace of the projects that came before it.
