High economic efficiency in the wind farm
The eno 114 also guarantees maximum farm yields in locations with increased environmental turbulence. 3,500 kilowatts of nominal power make the machines the most powerful On-Shore turbines in the 3-megawatt class and, with a perfect balance between robust, conservative machine design and highly innovative detailed solutions, the eno 114 achieves an unmatched packing density.
