Consultation on discounts, multipliers and seasonal factors for 2027 gas transmission tariff
On 1 September 2025 the President of ERO launched the 8th consultation, pursuant to Article 28 of Commission Regulation (EU) 2017/460 of 16 March 2017 establishing a network code on harmonized transmission tariff structures for gas (OJ L 72 of 17.03.2017, p. 29), concerning 2027 tariff.
The consultation with the regulatory authorities of all directly connected EU Member States and relevant stakeholders refers to:
a) the level of multipliers,
b) the level of seasonal factors and their calculations specified in Article 15 of the Tariff Code,
c) the levels of discounts at entry points from the LNG terminal and discounts applied to calculate the reserve prices for standard capacity products for interruptible capacity set out in Article 9(2) and Article 16 of the Tariff Code,
for a single combined natural gas entry/exit system[1], comprising the transmission network of Operator Gazociągów Przesyłowych GAZ-SYSTEM S.A., and the transmission network owned by the company SGT EuRoPol GAZ S.A.
During the consultation process spanning from 1 September to 1 November 2025, stakeholders may send their comments, opinions and proposals to a dedicated e‑mail address: konsultacje.nctar@ure.gov.pl, using an enclosed template.
The consultation is carried out simultaneously to the consultation of ‘The Consultation Document for the Entry – Exit System in the Republic of Poland for 2027-2031’, drawn up and consulted separately by GAZ-SYSTEM S.A., pursuant to Article 26 of the Tariff Code. A reference price methodology adopted in that document assumes that since 2027 the two separate entry/exit systems will be merged into a single natural gas entry/exit system in the territory of the Republic of Poland, for which the same method of reference price calculation will be applied jointly (an uniform transmission tariff will apply).
The President of ERO encourages participation in the consultations.
Note: In case of any inconsistencies between the Polish and English version of the consultation document, the Polish version shall prevail.
[1] Pursuant to Article 2 point 57 of Directive (EU) 2024/1788, ‘entry-exit system’ means an access model for natural gas or hydrogen where system users book capacity rights independently on entry and exit points, that include the transmission system and may include the whole or part of the distribution system, or hydrogen networks.
