Developed as a strong-wind system for the international market, the E-44 wind turbine sets the benchmark in the medium power range. As all other ENERCON wind turbines, the E-44 is also provided with ENERCON’s efficient rotor blade design. With a rated power of 900 kW, maximum use is made of prevailing winds at strong wind sites. TECHNICAL DATA Rated power: 900 kW Rotor diameter: 44 m Hub height: 45 m / 55 m Wind class (IEC): IEC/NVN I A Turbine concept: Gearless, variable speed, variable pitch control Rotor Type: Upwind rotor with active pitch control Direction of rotation: Clockwise Number...

ENERCON’s E-48 wind turbine is yet another success story in the company’s medium class power range. With a rated power of 800 kW and a sophisticated rotor blade design, the E-48 wind turbine is the most profitable system within its class. Together with a choice of different tower versions up to 76 m, the E-48 offers an economically sound solution to complex sites worldwide. TECHNICAL DATA Rated power: 800 kW Rotor diameter: 48 m Hub height: 50 m – 76 m Wind class (IEC): IEC/NVN II Turbine concept: Gearless, variable speed, variable pitch control Rotor Type: Upwind rotor with active pitch...

Developed for sites with medium wind speeds, the ENERCON E-53 wind turbine’s expanded rotor diameter and newly designed rotor blades guarantee maximum yield even at low wind speeds. TECHNICAL DATA Rated power: 800 kW Rotor diameter: 52.9 m Hub height: 60 m / 73 m Wind class (IEC): IEC/NVN S (vav = 7.5 m/s, vext = 57 m/s) Turbine concept: Gearless, variable speed, variable pitch control Rotor Type: Upwind rotor with active pitch control Direction of rotation: Clockwise Number of blades: 3 Swept area: 2,198 m2 Blade material: Fibreglass (epoxy resin); integrated lightning protection...

TECHNICAL DATA Rated power: 2,300 kW Rotor diameter: 71 m Hub height: 57 m – 113 m Wind class (IEC): IEC/NVN I and IEC/NVN II (depending on hub height) Turbine concept: Gearless, variable speed, variable pitch control Rotor Type: Upwind rotor with active pitch control Direction of rotation: Clockwise Number of blades: 3 Swept area: 3,959 m2 Blade material: Fibreglass (epoxy resin); integrated lightning protection Rotational speed: Variable, 6 – 21.5 rpm Pitch control: ENERCON blade pitch system, one independent pitching system per rotor blade with allocated emergency supply Drive train with...

Specially designed for medium wind speeds, the ENERCON E-82 wind turbine – with the new rotor blade design and tower versions up to 138m hub height – guarantees excellent yields in the 2 MW category, even at inland sites. TECHNICAL DATA Rated power: 2,000 kW Rotor diameter: 82 m Hub height: 78 m – 138 m Wind class (IEC): IEC/NVN II Turbine concept: Gearless, variable speed, variable pitch control Rotor Type: Upwind rotor with active pitch control Direction of rotation: Clockwise Number of blades: 3 Swept area: 5,281 m2 Blade material: Fibreglass (epoxy resin); integrated lightning...

ENERCON POWER CURVES According to current standards at power curve measurement certain parameters such as turbulence intensity are not taken into consideration. The results are deviating measurements on the same type of wind turbine at different locations. Also when comparing yield using power curve measurements from different types of wind turbines, a clear picture cannot be obtained unless all measurement parameters are taking into consideration. So in order to calculate power yield forecasts for its wind turbines, ENERCON does not use power curve measurements but calculated power curves....
