Another important milestone in the construction of the Polish wind farm "Jasna" has been reached: This week the first of a total of 39 turbines was completed.
Since the start of construction at the end of June 2019, approx. 70 km of high-voltage road, approx. 40 km of megavolt line, approx. 34 km of internal road network as well as compensation coil and substation have been constructed. On the one hand, the particular structural challenges are the size of the wind farm, i.e. 39 turbines with a north-south extension of approx. 17 km. On the other hand, particularly demanding is the connection route to the transformer station, which is approx. 70 km long and crosses two rivers, the Vistula and the Nogat. As part of the high-voltage transmission line, about 250 boreholes (microtunneling) must be created, the longest of which, at almost 1.5 km, crosses under the Vistula River.
After completion, the wind farm with a total nominal capacity of 132 mw will be one of Poland's largest onshore wind farms.
