One of the 400 kV lines connects the substation at Gönyű (110 km northwest of Budapest), in Hungary, to the hydroelectric power plant in Gabčíkovo, Slovakia. The other runs between Rimavská Sobota, Slovakia, and the Hungarian settlement of Sajóivánka (180 km northeast of Budapest).

MEKH chairman Péter János Horváth said the interconnectors would boost Hungary's cross-border capacity along its longest frontier and in the high-volume north-south direction, supporting delivery of electricity generated from renewable resources, too. He called the interconnectors a "significant step" in ensuring the energy supply of both countries, adding that they play "an important role" in shaping Europe's integrated electricity market.
