In late September, three European onshore turbine OEMs launched new models within the same week. Vestas unveiled the V182-7.2 MW on 21 September; Nordex followed suit the next day (22 September) with the N193/7.X; Enercon had already rolled out an efficiency-boosted version of its E-175 EP5 E2 in early September, and expanded its Yield+ upgrade programme for the E-138 EP3 E3 on 24 September.
On the surface, this line-up of four models amounts to a concentrated wave of product refreshes. In reality, it reflects three entirely distinct competitive logics.
Key Specifications of the Four Models
In terms of launch timing, the three players moved almost in lockstep. On 4 September, Enercon first introduced an efficiency upgrade for its flagship E-175 EP5 E2. Vestas launched the V182-7.2 MW on 21 September, followed by Nordex’s N193/7.X the next day. On 24 September, Enercon rolled out the Yield+ programme for its medium-duty E-138 EP3 E3. Within four days, all three major European OEMs had laid their new cards on the table.
The fiercest competition lies in rotor diameter. Nordex’s N193/7.X leads by a wide margin with a 193-metre rotor and a swept area of around 29,200 m² – roughly 12% larger than Vestas’ V182 (182 m, ~26,000 m²). Enercon’s E-175 EP5 E2 (175 m, ~24,000 m²) and E-138 EP3 E3 (138 m, ~15,000 m²) target separate market segments, covering different use cases with one larger and one smaller model.
Power rating and power density are also clearly differentiated. The Vestas V182 has a rated power of 7.2 MW and a power density of 277 W/m². Nordex’s N193/7.X peaks at 7.3 MW with a power density of around 250 W/m² – the lowest among the four. Lower power density translates to stronger performance at low wind speeds, making it clearly targeted at low-wind markets. Enercon’s E-175 holds steady at 7.0 MW with a power density of 291 W/m². The E-138 has a rated power of 4.26 MW, which can be boosted to up to 4.5 MW with Yield+ enabled, delivering a power density of around 285 W/m² (at 7.0 m/s reference wind speed).
The real divergence in strategy shows in how each model delivers efficiency gains. Vestas has scaled up its rotor for a hardware upgrade. Nordex combines a larger rotor with a higher power ceiling, pushing specifications on both fronts. Enercon’s two upgrades are both paid optional offerings: the E-175 boosts output through operational mode optimisation, while the E-138 increases power and yield via the Yield+ programme.
In terms of wind class positioning, both Vestas and Nordex target low-to-medium wind sites. Enercon’s E-175 is IEC Class S and the E-138 is IEC Class IIA, covering medium wind speeds with their respective portfolios.
The Rotor Diameter Race: Nordex Pulls Ahead
The most intriguing dynamic is the battle for rotor diameter supremacy.
Barely had Vestas’ V182 set a new European onshore record with its 182-metre rotor, when Nordex unveiled the N193/7.X the very next day, stretching the rotor to 193 metres – 11 metres larger than the V182. The timing was a direct response, and the specification a direct counter to its rival.
The N193 delivers a swept area of 29,235 m², 22% larger than the N175/6.X, with a 10% larger rotor diameter and over 11% higher torque. Its power density of around 250 W/m² is the lowest of the four models: lower power density means less loading per square metre of swept area, and higher generation efficiency in low wind speed ranges. This model was designed from the outset for low-wind markets.
Three Pathways: Hardware, Specification, Software
Looking deeper, the three players have chosen fundamentally different routes to higher efficiency.
Vestas is in the hardware camp. Holding rated power fixed at 7.2 MW, it has increased rotor diameter from 172 m to 182 m, boosting low-wind energy output by expanding swept area and lifting AEP by up to 6%. Built on the mature EnVentus platform with incremental upgrades, it benefits from proven supply chains and manufacturing processes, carrying the lowest execution risk.
Nordex is in the specification camp. Pairing a 193-metre large rotor with a 7.3 MW power ceiling, it pushes both swept area and rated power to the forefront of the industry on paper. However, volume production is scheduled for 2029 – a classic case of technology pre-positioning, unveiling the product first before ramping up manufacturing. There is a full three-year gap between its paper specifications and volume delivery.
Enercon is in the software camp. The flagship E-175 EP5 E2 sees almost no change to hardware parameters (7.0 MW, 175 m), and delivers a 5.5% AEP uplift purely through operational mode optimisation. Shortly after, it extended the Yield+ production boost programme to the medium-duty E-138 EP3 E3 (4.26 MW, 138 m), pushing rated power to 4.5 MW and lifting AEP by around 2% at 7.0 m/s sites, with a stated plan to roll the upgrade out to more models.
Notably, the E-138’s output uplift is essentially achieved by raising power output – a narrative not fully aligned with the E-175’s “same power, more energy” proposition. Strictly speaking, both of Enercon’s lines rely on software optimisation, differing only in whether they adjust the power ceiling.
Commercialisation Timeline: Vestas Fastest, Nordex Furthest Out
The three players are at markedly different stages of commercial rollout.
Vestas is moving the fastest. Shortly after the launch, it secured the first order for the V182 from Sweden’s Staverhult project: 4 turbines totalling 29 MW, with deliveries scheduled to start in Q2 2028 and commissioning in Q3, plus a 35-year AOM 5000 long-term service agreement. This forward order indicates the commercial value of the launch lies more in platform validation than immediate production volume.
Enercon has the most mature offering. The E-175 EP5 E2 prototype is already in operation, with a solid order backlog including 13 turbines at Germany’s Kutenholz wind farm and a 440 MW framework agreement (over 60 turbines) in Canada, making it the most commercially ready of the group.
Nordex is in technology pre-positioning mode. The newly launched N193/7.X will not enter volume production until 2029. Over the three-year lead time, supply chain maturity, certification progress and the performance of the first demonstration projects all remain unknown.
Taken together, the three players’ moves map out exactly three strategies for European turbine OEMs to compete in the market:
Vestas competes on deliverability, taking a steady approach with a proven platform to lock in orders and service agreements first.
Nordex competes on specifications, staking out the technical high ground with a 193-metre rotor and 7.3 MW power ceiling – at the cost of a three-year wait for volume production.
Enercon competes on differentiation, carving its own path with low-maintenance advantages and software optimisation, turning “yield uplift” into a paid optional service.
No single strategy is guaranteed to succeed. What is clear, however, is that the next generation of competition in European onshore wind has shifted from a single-minded megawatt race to a multi-dimensional contest spanning rotor size, power rating, software and reliability.
