The V166-4.5 MW™ complements the existing 4 MW portfolio and helps optimise your business case in low to medium wind conditions by enabling configuring to park with increased customisability.

V166-4.5 MW™ at a glance

The V166-4.5 MW complements the V163-4.5 MW and the V150-4.5 MW, enabling enhanced applicability in low to medium wind conditions and represents yet another incremental step forward in securing customer business case certainty. The slightly longer blades on the V166-4.5 MW optimise wind capture and power performance, while ensuring transportability. With the only difference being the blade length, the V166-4.5 MW and the V163-4.5 MW demonstrate how we leverage modular blade design to achieve product configuration flexibility, using standardised interfaces and same design principle to efficiently expand our product offerings to optimise your business case. 

The V166-4.5 MW helps increasing your project revenue through improving energy production, while ensuring business case certainty through capitalising on the well-established global supply chain and proven technology of the 4 MW platform.
