IN ITS CATEGORY
With its rotor blades of nearly 58 metres, the N117/2400 is
the largest wind turbine in its category. Its rotor diameter
is 17 metres longer than that of the N100/2500. In developing these rotor blades, Nordex has remained true to its
tried-and-tested technology: the profile and connection
system are the same as for the previous models from this
platform. In addition, Nordex has geared the rotor dimensions exactly to the requirements of lower wind locations.
Carbon fiber-reinforced plastic ensures the stability of
structures exposed to particular strain.

YIELD
The N117/2400 is specifically designed to generate high
yields even at low wind speeds. Its rotor sweep of 10,715
square metres – almost 3,000 square metres more than its
predecessors – results in a performance that is correspondingly impressive. The N117/2400 provides 17 percent more
yield compared to turbines previously offered for IEC 3
locations, making it the most efficient IEC 3 machine in its
power class.

3,500 FULL- LOAD HOURS
The N117/2400 sets the highest standards for economic
efficiency. Its rotor swept area output of around 4,500
square metres per megawatt sets a new record. Every year,
the N117/2400 notches up more than 3,500 full-load hours
at typical locations, outstripping other products in its
category by 20 percent. It achieves a capacity factor of up
to 40 percent. With the N177/2400 in regions with lower
winds, Nordex customers can ensure high and constant
production of electricity.

NOISE LEVEL IN THE MARKET
Attractive wind locations can be close to residential areas.
To design wind farms ideally for these spaces, a large
turbine with minimal noise emission is required. This is why
the N117/2400 does not exceed the sound power level of
105 decibels. The turbine also meets the structural height
limitation criterion: on the 91-metre standard tower, it is
below the critical overall height of 150 metres. Even on the
140-metre hybrid tower it is under 200 metres.

AND RELIABLE TECHNOLOGY
Experience is the key to building reliable power plants: the
N117/2400 is the result of eleven years of consistent technical development of the platform up to 2.5 megawatts.
In the year 2000, Nordex was the first manufacturer in the
world with a 2.5 megawatt series turbine. Step by step, the
company has built up a varied portfolio with machines for
every wind location and is today on the market with the
Gamma Generation, the Efficiency Class. The N117/2400
rotor giant adds yet another, even more powerful machine
to the Efficiency Class. Its design includes the knowledge
gained from 26 years of engineering in the wind industry
and experience from installing more than 4,400 wind
turbines. Nordex customers benefit from sophisticated
technology and an extremely robust design.
