The “ATRT7” tariff
The CRE published on January, 23rd 2020 its deliberation approving tariff of natural gas transmission system for GRTgaz and Téréga, the “ATRT7” tariff, entering into force from April, 1st 2020 for 4 years and yearly updated.
The trajectory defined for the 4 years (2020-2023) is an average increase of 1.4% per year. The ATRT7 tariff is a continuation of the previous tariff, both in its methodology for determining and updating it and in its structure, however with some new features:
- Introduction of a tariff term for biomethane injection that aims to take into account the operating costs (OPEX) of network reinforcements induced by location choices.
- Identical evolution in interconnection tariffs (entry/exit points at the borders of transport networks) throughout France.
The ATRT7 tariff includes evolutions proposed by GRTgaz in order to make the offer more attractive for customers with highly modulated and/or difficult to predict consumption. Examples include the reduction of winter monthly factors in January and February, the elimination of the second tranche of penalties for overruns, and the possibility of subscribing daily capacity intra-daily up to 2 p.m. on D.
ATRT7 also develops the storage compensation implemented since April 1st, 2018 with a change in the formula for calculating the base of T4/TP customers in distribution on April 1st, 2020 and an extension to customers connected to the transmission network from April 1, 2021.
