Enercon GmbH on Friday said it had installed the first prototype of its E-138 EP3 E2 wind turbine at the Janneby site in the German state of Schleswig-Holstein.
The installation was carried out without a hitch over the preceding days despite taking place under difficult conditions brought on by the coronavirus crisis, the German turbine maker said.
The E2 machine is rated at 4.2 MW, up from 3.5 MW of its E-138 EP3 E1 cousin. This is anticipated to translate into an additional yield of around 1.5 million kWh per year, equivalent to an increase of 10%. As a result, the E2 turbine will generate approximately 16.01 million kWh per year at sites where the mean wind speed reaches 7.5 m/s at hub height.
Highlighting the turbine's new features, Enercon said that the E2’s rotor head is fully plug-and-play enabled. Once fully assembled and tested at the factory, it can be shipped to the construction site as one delivery unit.
When the wind energy converter (WEC) is installed, the rotor head can be hoisted by crane with no need for any turning operations or complex additional equipment.
Additionally, Enercon employed a new time-saving installation method which does not require a ballast arm and the rotor head of the WEC can be turned using just the installation crane.
