CRE ATRT8 deliberation 

  • Flow scenarios are indicated in § 4.2.2.2.2
  • Evolution of capacity booked at entry and exit points is indicated in § 4.2.2.2.2 and Annex 3.
  • Distances taken into account are indicated in Annex 9

NaTran allowed revenue for 2024: 2083,6 M€ (excluding smoothing effects)

NaTran allowed revenue for 2025: 1961,2 M€ (excluding smoothing effects)

Excluding smoothing effects, allowed revenue decreases between 2024 and 2025, notably due to the difference between the final balance of the regulatory account for 2023 and the estimated balance, and lower energy expenses for 2024.
 

CRE ATRT8 deliberation

  • Types of assets, regulated asset base (RAB): § 2.2.2
  • Cost of capital: 4.1% (real, before tax) for ancient assets, 5.4% (nominal, before tax) for new assets, cf. § 3.1.4.1
  • Capital expenditures : § 3.1.4
  • Operational expenditures: § 3.1.3
  • Incentive mechanisms and efficiency targets: § 2.4, 2.5 and 2.6
  • Forecast inflation considered:  +4.8% in 2023; +2.5% in 2024; +2% in 2025; +2% in 2026; +1.8% in 2027

CRE ATRT8 deliberation

  • Transmission services revenue share amounts to 46% of total income, cf. § 4.2.2.1.4
  • Capacity – commodity split is 100%-0%. NaTran transmission tariffs are fully capacity-based
  • Entry-exit split between transmission services revenue is 34% (entries) / 66% (exits) and is described in § 4.2.2.2.1
  • Split in transmission services revenue between transit and domestic consumption is roughly 17% for transit and 83% for domestic consumption, cf. Annex 7

NaTran allowed revenue for 2024 : 2083,6 M€ (excluding smoothing effects)

CRE ATRT8 deliberation  

The CRCP balance as of 31 December 2024 corresponds to -42,4 M€ to be given back to network users.
Since the amount for differences for the year 2024 is provisional, the final value will be included in the CRCP balance as of 31 December 2025.
§ 3.1.3.1 of latest CRE tariff deliberation
Délibération de la CRE du 29 janvier 2025 portant décision sur l’évolution annuelle du tarif d’utilisation des réseaux de transport de gaz naturel de GRTgaz et Teréga au 1er avril 2025

  • Principle, calculation and reconciliation of the CRCP balance (§ 2.2.3, 2.3.5, 2.4.2 and Annex 4)

    For the present ATRT8 tariff, the CRCP balance is calculated as of 31 December each year. The CRCP balance is reconciled over a period of one year, within the limit of one tariff change associated with this reconciliation of +/-3%. If this limit is reached and does enable the balance of the CRCP to be fully reconciled in the tariff change of the following year, the non-reconciled balance for the year in question will be deferred to the following year.

     
  • Incentive mechanisms implemented for the regulatory account (§ 2.3.3)
    Items partly covered by the CRCP:
    • Energy costs (gas and electricity) and purchases and sales of CO2 emission allowances. To encourage the TSOs to control these expenses, the differences in this item are 90% covered by the CRCP for the portion between the actual amount and the reference amount less than or equal to, in absolute value, 50% of the reference amount. The fraction of the difference between the actual and reference amounts, in absolute value, in excess of 50% of the reference amount, is 100% covered by the CRCP. The reference amount is updated annually. The difference between the updated reference amount and the initial reference amount is fully covered by the CRCP;
    • The capital gain made on the disposal of real estate asset, 80% covered by the CRCP;
    • Costs for consumables (THT), 80% covered by the CRCP. The reference trajectory is updated annually. The difference between the updated trajectory and the initial trajectory is fully covered by the CRCP;
    • Transmission income from the main upstream network at interconnection entry points and from LNG terminals (PITTM) are 90% covered by the CRCP, to encourage TSOs to maximise subscriptions. The same applies for the following additional expenses and income:
      • income from access and transactions at the gas exchange point (PEG);
      • income from the Alizés balancing services;
      • income received in application of the use-it-or-lose-it (UIOLI) and use-it-or-buy-it (UBI) mechanisms;
      • income from the auction of daily capacity.

        The reference trajectory is updated annually. The difference between the updated trajectory and the initial trajectory is fully covered by the CRCP.
    • Differences in NaTran expenses linked to ANE (“avantage en nature énergie”) are 100% covered by the CRCP provided they relate exclusively to price differences to the electricity and gas price benchmark set by CRE (see confidential appendix 5); the remainder is not covered by the CRCP.
