The project will be implemented in the Podkarpackie Voivodeship, on the territory of Rzeszów in three locations. The subject of the Project is the modernisation of three WN/SN stations: Rzeszów Centralna, Rzeszów Staromieście and Staroniwa, whose aim is to adapt the existing 6 kV network located in the town of Rzeszów to work at a voltage of 15 kV. As part of the project, the 110/SN transformers will be replaced with 110/15 kV double winding transformers. Due to, among other things, the high level of operation of 110 kV devices and the need to increase power security, the Rzeszów Central and Staroniwa stations will reconstruct the 110 kV switchgear for the H 5 system in GIS technology and reconstructed SN switching system. At WN/SN Rzeszów Station, Centrala and Staroniwa will build a new station building with internal 110 kV switching room in the GIS system, 15 kV switching room, power transformers, PW and DG transformers, BKR stations, other rooms necessary for the operation of the GPZ. At the Rzeszów Staromieście station a new 15 kV distribution room will be built. All stations will also be replaced with power transformers (two in each station).
