HU-SK summer 2025 gas capacity nearly fully booked

Gas transmission capacity from Hungary towards Slovakia is almost entirely booked for the summer following near sold-out quarterly auctions on 3 February.

Following a decision in January to make higher capacity at Balassagyarmat/Velke Zlievce permanent, the additional 25.4 GWh/d of space was offered for the next two quarters, with 23 GWh/d allocated for both (see table). After these auctions, roughly 99.4 GWh/d out of total technical capacity of 101.8 GWh/d from Hungary towards Slovakia has been allocated for April-September, although bookings drop to 68.7 GWh/d from October, Entso-G data show.

Flows in this direction have been strong this year, averaging 87 GWh/d on 1 January-3 February, driven by Slovakia's need to replace Russian gas after the end of transit through Ukraine.

And on the Hungarian-Ukrainian border at VIP Bereg, roughly 35 GWh/d of unbundled exit capacity was booked. Flows to Ukraine at Bereg averaged 17 GWh/d on 1 January-3 February, well below 56 GWh/d in December. Interest in this capacity may have been spurred by buying interest from Ukraine's Naftogaz, although throughout last summer there were also quick flows at Bereg, which then transited to Poland making use of Ukraine's short-haul regime.

Elsewhere in the region, there was strong interest in quarterly bookings at VIP Brandov, on the German-Czech border, where 53 GWh/d was booked towards the Czech Republic for the second quarter and 48 GWh/d for the third quarter. Brandov has served as the only entry point for Czech supply since the turn of the year, as flows from Slovakia at Lanzhot dropped to zero after Russian transit halted. Given that the Czech Republic has national targets obliging a 90pc stockfill by 1 November, and storage was 51.4pc full as of Monday morning, there will probably be a need for a strong stockbuild this summer, necessitating inflows from Germany.
