ENERCON has erected the prototype of the new E-92 series.
The wind class IIA wind turbine was installed atop a 97-metre precast concrete tower in Simonswolde, Ostfriesland (Northern Germany). Immediately after the installation was complete, the team started working on the grid connection and commissioning of the new WEC. Work is scheduled to be completed by the end of the year.
ENERCON debuted the new E-92 at the Hannover Messe trade fair in April 2012.
The new machine has a rotor diameter of 92 meters and a nominal power of 2.3 MW and is specially designed for sites with less wind.
The newcomer complements ENERCON’s current product range, filling the gap between the E-82/2.3 MW and the E-101/3 MW. “The E-92 is a new wind turbine generation that will be popular in particular in many foreign markets”, says ENERCON Sales Director Stefan Lütkemeyer.
The redesigned rotor blade profile achieves maximum energy yields while ensuring optimal load distribution and reducing the rotor blade’s overall weight. Compared to the results of the established E-82 series, the E-92 can achieve up to 15 percent more yield.
That means that at an average near-shore location, the E-92 can produce more than 8 million kilowatt-hours (kWh) of green energy per year. This could provide a year’s worth of power to more than 2600 three-person households (average consumption: 3000 kWh).
Once the power curve rating at the prototype site in Simonswolde has been completed – by the end of the first quarter of 2013 – ENERCON will start the series production of the new turbine type. Planning is under way of the first large-scale projects, which include sites in Portugal, Sweden, and Canada.
