The Enercon E-126
is the largest wind turbine
A wind turbine is a device that converts kinetic energy from the wind into mechanical energy. If the mechanical energy is used to produce electricity, the device may be called a wind generator or wind charger. If the mechanical energy is used to drive machinery, such as for grinding grain or...

. With a hub height of 135 m (443 ft), rotor diameter of 126 m (413 ft) and a total height of 198 m (650 ft), this large model can generate up to of power per turbine. The nameplate capacity
Nameplate capacity, also known as the rated capacity, nominal capacity, installed capacity or maximum effect, refers to the intended technical full–load sustained output of a facility such as a power plant, a chemical plant, fuel plant, metal refinery, mine, and many others.For dispatchable power,...
was changed from to after technical revisions were performed in 2009. Enercon announced to further increase this capacity to , according to the Enercon Magazine
Indeed, since 2011 the E-126 is formally available as a windturbine with maximal 7.58 MW output.
The weight of the foundation of the turbine tower is about 2,500 t, the tower itself 2,800 t, the machine housing 128 t, the generator 220 t, the rotor (including the blade) 364 t. The total weight is about 6,000 t.

Enercon E-126 market
In September 2011, 132 Enercon E-126 windturbines were operating, in construction or nearing final approval.
Furthermore, during 2010-2011 many new onshore wind farm initiatives still in their early design processes were considering two options: a choice for wind turbines of the 2-3.5 MW class, or a variant choice for wind turbines of the 5-8 MW class. This approach is at least applied in the Netherlands. Examples for this trend are found for instance in the preliminary research for the “Wind farm de Drentse Monden” aiming at 300-450 MW with possibly 50-60 E-126/7.5 MW turbines, “Wind farm N33” aiming at >120 MW with possibly 15-40 E-126/7.5 MW turbines, “Wind farm Krammer” aiming at >100 MW with possibly 11-21 E-126/7.5 MW turbines, “Wind farm Wieringermeer” aiming 200-400 MW with possibly 60 or more 6+ MW turbines (in that case possibly Repower 6M/6.15MW).
