ÚRSO

SHERIDAN, WYOMING - March 31, 2026 - Gas shippers and large energy users in Slovakia face a tougher tariff-planning environment in 2026 because ACER has found that key elements of the country's proposed gas transmission pricing framework cannot yet be confirmed as aligned with EU tariff rules, creating potential changes to cost recovery, cross-border trade conditions, and final regulatory decisions. ACER's report reviews the reference price methodology proposed by Eustream, Slovakia's transmission system operator, for the 2026-2027 multi-year tariff period and sets out where the Slovak regulator ÚRSO should tighten the approach before adoption.
