Nordex SE has unveiled the fourth generation of
its MW scale Wind Turbines at the European wind power conference
EWEA, in Vienna Yesterday. Through this Turbine, the company is planning to tap the wind markets in the United
Kingdom and Ireland, Scandinavia, France, Turkey and Northern Germany.
“With Generation Delta we have reached a new stage
of evolution based on our proven multi-megawatt technology. Our foremost
goal was to lower the electricity production costs. The new Nordex
multi-megawatt turbines achieve an increase of up to 31 percent in
yields, making them a particularly worthy investment,” says Dr. Jürgen
Zeschky, CEO of Nordex SE.
Nordex’s Generation Delta comprises the N117/3000
with an installed capacity of 3.0 MW for medium wind speeds.This is a
20 percent increase in nominal output over its predecessor. Designed for
locations characterised by high wind speeds, the N100/3300 has an
installed capacity of 3.3 MW, resulting in a more than 30 percent
increase in nominal output.
The higher nominal output of these turbines
has a positive effect on energy yields. Yet, despite this substantial
increase in output, sound power levels have remained stable in both wind
classes.
At the same time, substantially larger rotors are
being used in both wind classes. Thus, the rotor diameter of the
N117/3000 has grown by 17 metres, resulting in an increase of around 37
percent in the rotor sweep and significantly higher efficiency with
around 10 percent higher number of full load hours. The N100/3300 has a
rotor diameter ten metres larger than its predecessor, driving the swept
area of the rotor up by 23 percent and contributing to even higher
energy yields.
In addition, the Generation Delta’s turbines come
with taller hub heights per wind class, enabling additional gains in
annual energy production and opening up complex forested sites for wind
turbine installations. Thus, Nordex is offering a steel tube tower with a
hub height of 120 metres for medium wind-speed locations for the first
time. The N100/3300 is now also available on a steel tube tower with a
hub height of 100 metres for strong-wind sites.
Nordex has also improved its product offering
substantially for cold regions. Generation Delta comes with Nordex’s
Anti-Icing system for the 58.5-metre rotor blades fitted to the
N117/3000 and also for the N100/3300. This is a first for strong-wind
locations. This system heats the aerodynamically most important surfaces
of the rotor blades, thus reducing ice formation efficiently.
Generation Delta has been designed to ensure
particularly swift and safe servicing. This lowers costs during
operations. A spinner, which completely encapsulates the rotor hub,
ensures quick and safe access to this part of the turbine. The turbine
nacelle is a particularly safe and spacious workplace and features
extended escape and rescue routes. Automatic lubrication of the pitch
bearing raceways does away with the need for manual attention to this
matter, thus further reducing and shortening on-site maintenance
requirements.
Nordex starts to deliver Generation Delta turbines
at the beginning of 2014. Initial projects involving the N117/3000 and
N100/3300 are being installed from mid 2013.
Nordex Recieves first Contract for N117/3000
Just one day after the public presentation of its Generation Delta wind
power systems, Nordex received its first contract for the delivery and
installation of a wind farm complete with Generation Delta turbines from
Raahen Tuulienergia Oy in Finland. At the EWEA 2013 in Vienna, Nordex
signed a contract with a joint venture forged by local grid operator
Raahen Energia Oy and Bridgehead Productions Ltd. Oy for two N117/3000
turbines each with an installed nominal output of 3 MW. The two
pre-ordered turbines are to be produced and installed this year.
