Vestas Unveils Larger-Rotor Turbine to Boost Onshore Wind Returns

By Charles Kennedy - Sep 21, 2026

Vestas has unveiled a new onshore wind turbine that uses a larger rotor to increase electricity production without raising the turbine’s 7.2-MW rated capacity, as developers face growing pressure to improve wind project returns.

The Danish turbine manufacturer said its new V182-7.2 MW can deliver up to 6% more annual energy production than the V172-7.2 MW, depending on site conditions, while also reducing the levelized cost of electricity.

The key change is a 182-meter rotor paired with the same 7.2-MW rating as its predecessor. That gives the turbine a lower specific rating and allows it to generate more effectively during periods of lower wind speeds.

Vestas said the design can increase capacity factors by as much as 2% compared with the V172-7.2 MW. More importantly for project economics, the company estimates the turbine could improve electricity capture prices by as much as 3% because it can produce a greater share of its power during lower-wind periods when wholesale electricity prices may be higher.

That distinction is becoming increasingly important for wind developers. As renewable penetration rises, generating the maximum amount of electricity is not always the same as maximizing revenue. Projects increasingly need to account for grid congestion, periods of low or negative power prices and the timing of electricity production.

The V182-7.2 MW is aimed primarily at low- to medium-wind locations in Europe, Australia, South Africa and the Americas, although Vestas said the model is suitable for a wider range of global markets.

Rather than developing an entirely new turbine platform, Vestas has based the machine on its existing EnVentus architecture. The platform has more than 15 GW of installed capacity and is operating in more than 25 countries, giving the company an established technology base from which to increase rotor size and output.

The strategy reflects a broader push by turbine manufacturers to extract additional energy and improve economics from established platforms while limiting the development and execution risks associated with completely new turbine designs.

For wind developers and investors, the commercial proposition is straightforward: more generation from the same rated capacity could improve returns without requiring a corresponding increase in the turbine’s nameplate output.
