Nordex Locks In 525 MW for Türkerler's Sivas Wind Project - the Largest Single Turbine Deal in Turkey's History

Nordex has secured a contract from Türkerler Holding to supply and install 72 N175/6.X turbines totalling approximately 525 MW at the YEKA-5 R25 Sivas wind project in central Türkiye^[1] - and the company says it is the largest single turbine deal ever concluded in the Turkish wind energy market.

That claim matters. Turkey has been one of the most active onshore wind markets in Europe for the better part of a decade, and a 525 MW single-model order is a meaningful data point about where the country's build programme is heading. The contract is signed. Engineering and procurement work is slated for completion this year, with first turbine installation scheduled to begin in Q3 2027 and commercial operations targeted for 2028. That's the sequence that counts.

What the Contract Actually Covers

The order covers the supply and installation of 72 N175/6.X turbines and includes a 10-year Premium Service agreement with an extension possibility up to 25 years. The 72 units from the Delta4000 series will be installed at the YEKA-5 R25 Sivas site with a 108-metre hub height.

The project sits in Sivas province in central Anatolia. Nordex said the project site's strong and consistent winds made it well suited to the N175/6.X model. That's a relevant point: the N175/6.X is Nordex's specialist for low-to-medium wind regimes, and Sivas is not a coastal site. The choice of a 108-metre hub - lower than the turbine's maximum available tower height - suggests the wind resource at elevation is strong enough that the additional hub height isn't needed to hit the economics.

What the announcement does not disclose: a power purchase agreement, project financing, or a grid connection confirmation. The signed supply contract is the anchor here. Whether the project reaches financial close on schedule will depend on those elements, which Türkerler has not made public.

The N175/6.X: What the Turbine Actually Does

At typical low-to-medium wind locations, the N175/6.X achieves between 7 and 14 percent more yield compared to its sister models, the N163/5.X and N163/6.X, due to its single-piece, newly designed 85.7-metre-long rotor blade and its above-average capacity factor. This additional yield is achieved particularly during times of lighter wind speeds, with the turbine producing up to 22 percent more energy than its predecessors.

The platform has been moving fast commercially. Nordex has already secured more than 3 GW of firm orders for the turbine, reflecting strong market demand. And the product is still being upgraded: Nordex introduced a new power mode with a 7.3 MW nominal rating for the N175/6.X, with the new power mode enhancing annual energy production by up to 1.7 percent while sound power levels remain unchanged.

For the Sivas project, Nordex has not specified which power mode will be used. At 72 turbines and 525 MW nameplate, the implied per-unit rating is approximately 7.3 MW - consistent with the highest available power mode. That's worth watching when the project reaches commissioning.

Nordex's Position in Turkey - and Why It Matters

With this order, the Nordex Group is further strengthening its position in the Turkish wind market with a cumulative market share of 34 percent. The company has been active in the country since 2009 and has established itself as market leader since 2017.

That dominance is now backed by in-country manufacturing. The Nordex Group started production at its new blade manufacturing facility in Menemen, İzmir in May 2026. The new site, located in the İzmir Free Trade Zone, covers a total land area of approximately 130,000 square metres, with a production building of around 90,000 square metres. At full capacity, the plant is designed to manufacture up to 1,200 rotor blades per year operating in four shifts, employing around 1,200 people across production and administrative functions.

Initially, the plant will prioritize supplying blades for projects awarded within the YEKA-4 and YEKA-5 programmes. The Sivas project falls under YEKA-5. That means the blades for these 72 turbines are likely to come off a production line three hours' drive from Istanbul - a supply chain arrangement that satisfies Turkey's local content requirements and insulates the project from the kind of logistics disruption that has plagued European wind builds in recent years.

Nordex CEO José Luis Blanco noted that "by investing in local production capacity, we are not only contributing to the development of the wind industry in Türkiye but also enhancing our ability to fulfill further all local content requirements in accordance with the YEKA specifications."

The Market Context: Turkey's YEKA Programme and the 120 GW Target

The Sivas order doesn't exist in isolation. It is one piece of a government-directed buildout that has been accelerating.

Türkiye's total installed electricity capacity reached 125 GW as of March 2026, with wind energy accounting for a 12 percent share at 15 GW, while combined with 26.5 GW of solar power, renewables made up 62 percent of the total.

Türkiye surpassed 2 GW in new wind installations in 2025 and ranked second in Europe for wind power expansion. The government wants to keep that pace - and then some. Turkey launched a 2.4 GW renewable energy tender for solar (900 MW) and wind (1.5 GW) in YEKAs, with bids opening October 13, 2026. Data from the think tank Ember indicates that the pace of renewable energy additions will need to increase to meet these targets - combined solar and wind additions in Turkey reached 6.5 GW per year in 2025, which is below the 8 GW of annual deployments required to meet the 2035 targets.

That gap is the structural driver behind orders like this one. The YEKA mechanism - which bundles capacity allocation with local content requirements - is designed to pull through exactly the kind of integrated supply chain investment Nordex has made in Menemen.

Türkerler: A Repeat Customer With Scale

Türkerler Holding is active in construction, energy, healthcare, real estate development, renewable energy, electricity distribution and trading, public-private partnership projects, and textiles. Türkerler Holding is described as a regular customer of Nordex Group. The relationship predates this order - Nordex referenced "success in earlier YEKA projects" in its announcement, which means Türkerler has already taken delivery of Nordex turbines and the service relationship is established.

That matters for the 10-year service agreement. A new customer signing a long-term O&M contract with a turbine OEM carries more uncertainty than a repeat buyer who already knows what the service model looks like in practice. Türkerler knows what it is buying.

What to Watch

Three things will determine whether this project lands on schedule.

First, grid connection. Sivas is an inland province. The transmission infrastructure serving central Anatolia has historically been a constraint on wind development in the region. No grid connection agreement has been disclosed.

Second, financing. A 525 MW project of this scale will require project finance. Türkerler has not announced a lender group or a PPA. Turkey's energy market has a government-backed feed-in tariff mechanism (YEKDEM) and a competitive contract-for-difference structure (YEKA). Which revenue structure underpins this project will determine the financing terms.

Third, blade supply. The Menemen plant opened in May 2026 and is ramping toward 1,200 blades per year. Delivering 216 blades (three per turbine) for a Q3 2027 installation start requires the plant to be producing at meaningful volume within the next 12 months. That is achievable but not trivial for a facility in its first year of operation.

The YEKA-5 R25 Sivas project involves 72 N175/6.X turbines at 108-metre hub height, with first installation targeted for Q3 2027 and commercial operations in 2028.

The signed contract is real. The turbine is proven - the N175/6.X has accumulated more than 3 GW of firm orders globally. The supply chain is in-country. What the project still needs is a disclosed revenue structure and a confirmed grid connection. When those appear, the 2028 commissioning date becomes credible. Until then, it's a well-positioned project with a signed equipment order - which, in the current market, is further along than most.
