(point 3.1.5.1 of CRE deliberation: ATRT7).

Art. 30 (1) (b)(ii)

Information related to changes in the revenue

Excluding Inter-operator payment 2020 allowed revenue therefore changes by -0.7% between 2018 and 2020 (mainly related to the drop in the rate of return), and by +1.4% per year on average over the ATRT7 period.

(point 3.1.5.1 of CRE deliberation: ATRT7).

Art. 30 (1) (b)(iii)

Information related the following parameters: types of assets, cost of capital, capital and operational expenditures, incentive mechanisms and efficiency targets, inflation indices

CRE deliberation: ATRT7
- Types of assets, regulated assets base (RAB), capital charges (expenditures) point 2.1.2
- Cost of capital 4.25% point 3.1.3.1
- Capital expenditures point 3.1.3
- Operational expenses point 3.1.2
- Incentive mechanisms and efficiency targets points 2.3, 2.4 and 2.5
- Forecast inflation considered: +1.3% in 2019; +1.5% in 2020; +1.6% in 2021; +1.7% in 2022; +1.8% in 2023

Art. 30 (1) (b)(iv,v)

Information on the transmission services revenue including capacity-commodity split, entry-exit split and intra-system/cross-system split

CRE deliberation: ATRT7

- The transmission services revenue share amounts to 46% of total income point 4.2.1.1.4
- Capacity - Commodity split is 100%-0%. GRTgaz transmission tariffs are fully capacity-based
- The entry-exit split between transmission services revenue is 34% (entries)/66%(exits), and is described in point 4.2.1
- The split in transmission services revenue between transit and domestic consumption is roughly 24% for transit and 76% for domestic consumption – Annex 4

Art. 30 (1) (b)(vi)

Information related to the previous tariff period regarding the reconciliation of the regulatory account (CRCP)

GRTgaz allowed revenue for 2019 - 1 795.3 million € point 2.1.8 of CRE deliberation: CRE website

CRE deliberation: ATRT7

The CRCP balance as at 31 December 2019 therefore corresponds to the return of a sum of €33.5 million to be recovered by GRTgaz. The amount of the CRCP balance as at 31 December 2019 will be spread across four years and included in the allowed revenue for the ATRT7 period. Since the amount for differences for the year 2019 is provisional, the final value will be included in the CRCP balance as at 31 December 2020 (point 3.1.4.1)

The CRCP balance as at 31 December 2019 will be adjusted in four constant annual instalments of +€8.7 million (point 3.1.5.1)

- Principal, calculation and reconciliation of the CRCP balance points 2.1.3, 2.2.4, 2.2.5 and Annex 8

For the present ATRT7 tariff, the CRCP balance will be calculated as at 31 December each year. For each TSO, the CRCP balance will be reconciled over a period of one year, within the limit of one tariff change associated with this reconciliation of +/-2%. If this limit is reached and will not 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 point 2.3.3

The items partly covered in 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 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;

- the capital gain made on the disposal of real estate asset, 80% covered (see point 2.1.2.4.2);

- costs for consumables (THT), 80% covered in 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 80% covered, 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.

Art. 30 (1) (b)(vii)

Information on the intended use of the auction premium.

CRE deliberation: ATRT7 point 5.1.3

For the period from 1 November 2019 to 30 September 2020, all surplus revenue from auctions received over this period will be redistributed in one payment, in proportion to the quantities of gas delivered to end customers connected to the transmission network or distribution network in France from 1 November 2019 to 30 September 2020.

The individual amounts for redistribution for the period from 1 November 2019 to 30 September 2020 will be calculated by each TSO and redistributed in the bill for November 2020 at the latest.

Each TSO will publish on its website the unit amount of surplus auction revenue so redistributed.
