TAKING FLEXIBILITY TO THE NEXT LEVEL
With the new N149/5.X and the N163/5.X, we have incorporated our experience from developing and testing the Delta4000 series and driven our flexibility approach to the next level. Both new 5.X turbines cover a wide range of power modes in the 5 MW+ class and increase the competitiveness even further in light and medium-wind sites.
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.
Delta4000 architecture certified on site
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 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.
