The planned two-system 2 x 400 kV Cirkovce–Pince transmission line will be 80.5 km long and will have 263 pylons and a protective rope with built-in optical fibres. Within the framework of this project, a new 110 kV switchyard will be reconstructed in the existing substation 220/110 kV Cirkovce, a new 400/110 kV switchyard with a new control building will be constructed on the extended part, and the calibration of the existing 110 kV transmission lines in front of the extended substation will be performed.
The Cirkovce-Pince transmission line and the new Cirkovce switchyard will enable the implementation of the first international connection by transmission network with the neighbouring Hungary. One system of the anticipated transmission line will be electrically connected to the substation Heviz in Hungary, and the other to the substation Žerjavinec in Croatia. This will increase the reliability of the Slovenian electric power system, significantly increase the import transmission capacity and reliability of the transmission network in this part of the country and improve the reliability of power consumption in Slovenia in the event of outages of major production facilities or other unforeseen events and operational difficulties when additional support has been enabled through the Hungarian transmission network.
The project will enable greater market integration in the region and facilitate access to Eastern European electricity markets, which in the long-term will result in a preferential electricity tariff for Slovenian customers and consequently increase the competitiveness of the Slovenian economy and Slovenian products on world markets. The new substation Cirkovce will also unburden the existing substation Maribor.
