Poland 6 Construction of the 400 kV Line

Transmission Line Construction & Substation Expansion

ELTEC50Hz Gridworx executed key works on a major 400 kV transmission corridor, supporting both new line construction and substation expansion.

The scope covered the extension of the Świebodzice (400/200/100 kV) and Mikułowa (400/200/110 kV) stations, along with the construction of the first 400 kV line track and a second 220 kV line track. Works included HV and MV primary and secondary circuit implementation, as well as secondary systems within the Wrocław power station.

The result is enhanced transmission capacity and improved grid connectivity across the network.
