Annual calculation periods

Prices or fee rates included in the tariff will be calculated for a period of 12 months (W Dzienniku Ustaw ukazało się rozporządzenie ME ws. kalkulacji taryf gazowych (dokumentacja) – pap.pl). The basis for the calculation is the costs justified for the specific activity. The Minister of Energy's act, signed on 20 October 2026, was published in the Journal of Laws on 28 October as Dz.U. 2026 poz. 1418, and takes effect on 29 October (Rozporządzenie Ministra Energii z dnia 20 października 2026 r. w sprawie sposobu kształtowania i kalkulacji taryf oraz rozliczeń w obrocie paliwami gazowymi – Dziennik Ustaw RP).

Scope of activities covered by the tariff

The new rules define how tariffs are shaped, how their level is calculated, and how trade in gaseous fuels is settled. The calculation of justified costs refers to the separated activity of the gas enterprise.

What it means for businesses

The annual calculation horizon links tariff rates to the costs incurred in the same period. For companies buying gas, this means that tariff changes occur in a twelve-month cycle, not at any given moment. For sellers and distributors of gaseous fuels, the regulation sets the framework within which they submit prices and fees for approval.

Deadlines

The act takes effect on 29 October 2026. It replaces the earlier rules for calculating gas tariffs.
