High economic efficiency in the wind farm
The eno114 also guarantees maximum farm yields in locations with increased environmental turbulence. 4,800 kilowatts of nominal power make the machines the most powerful On-Shore turbines in the 4-megawatt class and, with a perfect balance between robust, conservative machine design and highly innovative detailed solutions, the eno114 achieves an unmatched packing density.
