Wind development across Southeast Europe is entering a more capital-intensive and structured phase, with turbine procurement increasingly concentrated among a narrow group of European manufacturers. As projects scale from early-stage deployments into 100–400 MW clusters with integrated grid and financing structures, the choice of OEM has become a central determinant of bankability, execution risk and long-term asset performance.
Across Serbia, Montenegro, Romania, Bulgaria and Greece, the same names recur with notable consistency—Vestas, Siemens Gamesa and Nordex—supported selectively by GE Vernova and, in emerging cases, Chinese OEM entrants testing the boundaries of EU-aligned procurement frameworks.
Core suppliers anchoring SEE wind projects
Vestas: Dominant onshore platform across the region
Vestas has established itself as the most geographically diversified supplier in Southeast Europe, with a strong footprint across Romania, Bulgaria, Greece and Serbia’s emerging pipeline.
The company’s positioning reflects three structural advantages:
• Proven turbine platforms in the 4–6 MW class, aligned with regional wind regimes
• Strong relationships with international lenders and IFIs
• Integrated service models supporting 15–25 year O&M contracts
In Romania alone, where installed wind capacity exceeds 3 GW, Vestas remains one of the principal suppliers, particularly in repowering and extension phases. In Greece, its turbines are embedded across multiple utility-scale projects backed by international capital.
For developers in Serbia and Montenegro, Vestas often represents the baseline bankable option, particularly for projects targeting export-oriented power markets or cross-border balancing.
Siemens Gamesa: Offshore leadership, selective onshore presence
While Southeast Europe remains primarily an onshore wind market, Siemens Gamesa plays a strategic role through:
• High-capacity turbine platforms
• Integration with grid and system-level solutions
• Strong positioning in EU-backed infrastructure projects
Its presence is most visible in Greece and Romania, where projects are increasingly aligned with EU decarbonisation frameworks and cross-border electricity flows.
In Montenegro, the signed agreement between EPCG and Nordex for the Gvozd II wind project (~50 MW) highlights the competitive dynamic, where Siemens Gamesa often competes but is selectively deployed depending on financing structure and project design.
Nordex: Aggressive expansion in SEE growth markets
Nordex has emerged as the most active challenger across Southeast Europe, particularly in markets where:
• Cost competitiveness is critical
• Projects are mid-sized (50–200 MW)
• Developers seek flexible commercial structures
Its selection for Gvozd II in Montenegro, alongside earlier deployments in Serbia (Čibuk wind farm vicinity supply chains) and Croatia, reflects its increasing penetration.
Nordex’s strategy is built around:
• Competitive CAPEX positioning
• Modular turbine platforms suited to complex terrain
• Willingness to engage in emerging markets with higher perceived risk
In practical terms, Nordex is becoming a preferred supplier for regional utilities and hybrid public-private developments, where cost and execution speed outweigh brand premium.
GE Vernova: Targeted presence via legacy and service contracts
GE maintains a more selective footprint in Southeast Europe, often anchored in:
• Earlier-generation projects
• Long-term service agreements
• Specific developer relationships
While not leading new installations at scale, GE’s installed base provides it with ongoing influence, particularly in maintenance and repowering discussions.
Case anchors across Southeast Europe
The regional project pipeline illustrates how tightly OEM selection is linked to financing and execution frameworks.
In Serbia, wind capacity has surpassed 500 MW installed, with projects such as Čibuk (158 MW) and Kovačica (105 MW) setting early benchmarks. Future developments—particularly hybrid wind + battery systems—are expected to rely on Tier-1 OEMs aligned with lender requirements, effectively limiting supplier diversity.
In Montenegro, the operational Krnovo (72 MW) and Možura (46 MW) projects established the initial market, while Gvozd II (~50 MW) signals a new phase of expansion. The involvement of Nordex reflects a shift toward more competitive procurement, but still within a tightly controlled OEM universe.
In Romania, the largest wind market in SEE, capacity exceeds 3 GW, with a new wave of projects supported by EU recovery funds and CfD mechanisms. Here, Vestas and Siemens Gamesa dominate, particularly in large-scale developments exceeding 100 MW.
In Bulgaria and Greece, similar patterns emerge. Greece’s wind fleet, now exceeding 5 GW, is heavily supplied by Vestas and Siemens Gamesa, with increasing integration into regional power markets and interconnections.
Emerging entry: Chinese OEMs testing the market
Chinese turbine manufacturers—particularly MingYang and Goldwind—are beginning to explore Southeast Europe, focusing on:
• Serbia
• Bosnia and Herzegovina
• Select Balkan markets outside strict EU procurement frameworks
Their value proposition is clear:
• Lower upfront CAPEX (often 10–20% below European OEMs)
• Vendor financing options
• Flexible delivery timelines
However, penetration remains limited due to:
• Bankability concerns among European lenders
• Grid compliance requirements (ENTSO-E standards)
• Political and regulatory sensitivities
In practice, Chinese OEMs are most likely to enter through merchant or privately financed projects, rather than IFI-backed developments.
CAPEX, financing and OEM selection
Wind turbine procurement in Southeast Europe is no longer a purely technical decision—it is a financing decision.
Typical onshore wind CAPEX in the region ranges between:
• €1.1–1.4 million per MW, depending on terrain, grid connection and turbine selection
Within that envelope, turbines account for:
• 65–75% of total CAPEX, making OEM choice the single largest cost driver
More importantly, lenders—particularly EBRD, IFC and commercial banks—strongly prefer:
• Proven OEMs with large installed bases
• Long-term service agreements
• Established performance data
This creates a structural barrier to entry and reinforces the dominance of European suppliers.
Grid constraints and turbine strategy
Southeast Europe’s grid limitations are beginning to influence turbine selection.
Developers increasingly prioritise:
• Turbines with advanced grid-support capabilities (LVRT, HVRT)
• Flexible output profiles compatible with balancing markets
• Integration with battery energy storage systems (BESS)
This further advantages established OEMs, which can offer:
• Integrated solutions
• Compliance with evolving grid codes
• Proven performance under regional conditions
Strategic positioning of SEE in the European supply chain
Southeast Europe is emerging as a growth frontier rather than a manufacturing hub within the European wind ecosystem.
While turbine production remains concentrated in:
• Denmark
• Germany
• Spain
SEE contributes through:
• Project development pipelines
• Grid expansion
• Increasing role in balancing and cross-border electricity flows
However, there is a growing opportunity for the region to move upstream in the value chain, particularly in:
• Component manufacturing (towers, cables, substations)
• Engineering and EPC services
• O&M support centres
Countries such as Serbia, with established heavy-industry capacity, are particularly well positioned to capture this segment.
A concentrated but expanding market
The Southeast European wind market is expanding rapidly, but within a tightly defined industrial structure.
A small group of OEMs—Vestas, Siemens Gamesa and Nordex—continue to dominate turbine supply, reinforced by financing requirements, grid compliance and established performance records.
At the same time, the market is becoming more competitive:
• Nordex gaining share in mid-sized projects
• Chinese OEMs probing entry points
• Developers seeking cost optimisation under tighter financing conditions
As project sizes increase and hybrid systems become standard, turbine supply is evolving from a procurement decision into a strategic partnership, linking developers, lenders and OEMs over multi-decade asset lifecycles.
In that system, Southeast Europe is no longer a peripheral market. It is becoming an integral part of Europe’s wind expansion—one where the balance between cost, bankability and system integration will determine which suppliers ultimately secure the region’s next generation of projects.
