Highly flexible siteability

ADAPTABLE TO VARIOUS SITE CONDITIONS

With the N149/4.0–4.5, the Nordex Group was the first company to launch a turbine with a flexible rating as part of its core design philosophy and operation strategy. This design approach, combined with a variety of operating modes, enables the utilization of the N149/4.0–4.5 across a large range of projects – from medium wind projects in Australia to highly complex sites in Germany or Scandinavia.

Introducing the Delta4000

PROVENT TECHNOLOGY

The N149/4.0-4.5 prototypes were installed in the summer of 2018, meaning the main warranted performance figures, such as the power curve and most relevant sound power modes, have already been confirmed by measurements from certified third parties.

The strategy- evolutionary

CONNECTING PROVEN TECHNOLOGY WITH INNOVATIVE ENGINEERING

For the Delta4000 product series, we took over the Delta
Generation’s fundamental design and transferred it to the 4 MW class.

Depending on investment criteria of the customer’s business case, the wind farm can be optimized with in terms of AEP, rating, lifetime and sound requirements. In addition, this flexibility offers opportunities to optimize the revenues in line with PPA structures and merchant price profiles.

1. OPTIMIZED POWER TRANSFER
2. LARGER ROTOR DIMENSIONS
3. REDUCED SERVICE EFFORTS
4. MAINTAINED ELECTRICAL SYSTEM
5. RELIABLE DRIVETRAIN CONCEPT
6. GRID COMPATIBILITY GUARANTEED
