On Křížovém vrch (691m) above the village of Kopřivná, a pair of giant wind power plants have grown. The construction of a wind park in the locality has been planned for a long time, originally the construction of 15-18 windmills was planned here, so two have been built so far. And since they are not sharpeners, they attract quite a large audience. The power plants used should be of the Enercon E-82 type. If the reports are not false, the height of the power plants is supposed to be up to 150m, that would correspond to the specification stated by the manufacturer that the column itself should be 108m high, the rotor blade should be 41m long, that would almost give the sum of the 150m.
