Enercon has introduced low-wind speed versions to its 4MW and 2MW onshore wind turbine platform.
Its E-141 EP4 machine offers better aerodynamic efficiency, higher resistance to dirt and lower noise levels. To improve the production process the rotor blades will be divided into two parts like the E-115 model.
It has power output of 4.2MW and Enercon claims it will generate over 13,000MW of energy each year even at low wind sites and sound emission are 105.5 dB(A). A prototype has been scheduled for late 2016 with series production starting in 2017.
The E-103 EP2’s output is 2.35MW with sound levels of 105.0dB(A). Annual energy capacity is up to 10% higher than the E-92. Series production is scheduled for 2017.
The release of both wind segments completes Enercon’s two platforms in the 2MW and 4MW power classes.
Enercon has also announced that its E-115 model has increased output from 3MW to 3.2MW, increasing annual yield by about 3%
Enercon managing director Nicole Fritsch-Nehring said: “These new wind energy converters are another contribution to implementing ENERCON’s product strategy that aims at offering customers a most efficient WEC with regard to power output and profitability for any site.
“We are going to continue driving the development of technologies with a high potential for innovation in order to lower power generation costs while increasing WEC efficiency.”
