Designed for growth markets

Optimized performance for markets with less complex sites

The N155/5.X leverages already developed components of the current 5.X series – the N149/5.X and the N163/5.X – to boost annual energy production per wind turbine. This variant improves competitiveness in stronger wind conditions or in situations where fewer wind turbines on a grid-constrained project result in a better overall cost of energy.
This applies for many locations worldwide, but will fit optimally in much of the United States, Latin America, South Africa, and Southeast Asia, and represents a large segment of projects being developed in large growth markets.

The turbine leverages the fully tested and certified architecture of the Delta4000 nacelle,features a hydraulic hub system in conjunction with blades that have a glass fiber spar cap construction.
It capitalizes on the modular platform concept of the Delta4000 by integrating an upgraded drive train and electrical system to facilitate higher power rating. First certifications and WTG deliveries in Mid 2021.

PROVEN TECHNOLOGY

With the Delta4000 platform the Nordex Group builds upon the Delta Generation’s fundamental design and has transferred it to the 5 MW+ class with the help of performance-enhancing concept adaptations. The N155/5.X leverages on the N155/4.X hub and nacelle components as well as blades to capture the supply chain as well as O&M synergies and benefits from existing blade & tower molds.

The Strategy: Evolution

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 the investment criteria of the customer’s business case, the wind farm can be optimized 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
