A glance at the guest list of the official ceremony for the start of construction of the Cirkovce-Pince overhead line reveals that a major project has been launched here. The Slovenian transmission system operator (TSO) ELES had the honour to welcome both the Slovenian Prime Minister Janez Janša and his Hungarian counterpart Viktor Orban to the opening event for the new construction. And indeed, the project is of historic proportions, as the 400kV AC line, a good 80 kilometres long, will be the first interconnector between the Slovenian and Hungarian transmission systems.
The double circuit line with 264 pylons will increase the operational reliability of the Slovenian transmission system and import transmission capacity, facilitate access to energy sources from the North and East, and allow for the integration of larger amounts of renewable energy from the whole region into the grid. The line runs from the Cirkovce substation in the northeastern Slovenian region of Lower Styria to the border settlement of Pince, which is not only on the Hungarian border, but also in the triangle of Slovenia, Croatia, and Hungary. Therefore, in addition to the substation of the Hungarian TSO MAVIR in Hévíz in Zala County, the substation of the Croatian TSO HOPS in Žerjavinec near Zagreb can also be connected to the new line, truly a European Project of Common Interest (PCI). The power line will thus even interconnect three countries. The presence of Gordan Grlić-Radman, Croatian Minister of Foreign and European Affairs, confirmed the trinational dimension of the Cirkovce-Pince line.
At the ceremony with symbolic unveiling of the construction panel, Aleksander Mervar, CEO of ELES, illustrated the supraregional significance of the power line: “This project is of great importance not only for Slovenia but also for the wider region and Europe. That is why this project was included on the list of Projects of Common Interests in 2015, while in 2019 we managed to acquire €50m funds.” Mr Mervar also explained that the project, which includes major upgrades of switchgears in Cirkovce, is the largest investment in transmission infrastructure in the history of ELES, totalling some €150m. Finally, he emphasised the good cooperation of the three TSCNET shareholders ELES, HOPS, and MAVIR: “Without this cooperation, this project would surely not be happening today.”
