ENERCON has successfully commissioned its first E-126 EP3. The prototype in Kirch Mulsow (Mecklenburg-Western Pomerania) has been feeding kilowatt-hours into the grid since Monday evening. The new wind energy converter has met all of the developers' expectations: the EP3 team at ENERCONs research and development company WRD is pleased with the way the installation and commissioning phase and the first operating hours have turned out.

The new EP3 platform machines represent a radical cut in ENERCON’s wind energy converter design. They are compact and efficient with consistently optimised processes – from production, transport and logistics to installation. These are the key characteristics of the new WEC generation ENERCON has designed in response to new market requirements worldwide.

The E-126 EP3 designed for wind class IIA zones (IEC) with a rotor diameter of 127 metres is available in the performance levels 3.0, 3.5 and 4.0 MW. Installation of the first customer projects will start this autumn.

At the same time, ENERCON is also pushing ahead with the EP3 sub-projects E-138 and
E-115. The prototype of the E-138 EP3 designed for wind class IIIA locations is to be installed by the end of the year, with the first series WECs to follow in 2019. The prototype of the newly developed E-115 EP3 strong-wind turbine is planned for the third quarter of 2019.

On top of this, ENERCON will be presenting the E-138 EP3 E2 for wind class IIIA at the WindEnergy trade fair in Hamburg (25 to 28 September). “The aim of this development is to bring about a further significant reduction in energy production costs”, explains Stefan Lütkemeyer. The developers expect an energy yield approximately up to 10 percent higher than with the E-138 EP3 E1 at a mean wind speed of 7.5 m/s. The E-138 EP3 E2 will have a nominal power of 4.2 MW and a rotor diameter of 138.6 metres. Steel and hybrid tower versions with hub heights from 81 to 160 metres are being considered. The planned service life is 25 years. Installation of the prototype is scheduled to take place by the end of 2019.
