A) Border interconnection points as well as storage and network connection points:

The precise forecast of the booking quantities for each point and direction (including the distribution to the different capacity products and contract periods) was based on various input parameters (e.g. transport bookings and allocations) using time series analyses. The current geopolitical situation was also taken into account.

B) Virtual Interconnection Points (VIP)

The determination of the capacity forecast is based on the rules of Art. 22 NC TAR.

C) Internal orders:

The capacity framework for outgoing zones and interconnection points to downstream network operators is based on the long-term forecasts of the downstream network operators for the period from 01.01.2023 to 01.01.2024, which are available to OGE on 18.11.2022.

incentive mechanisms and efficiency targets

German transmission system operators are subject to the incentive regulation system. The revenue cap of a transmission system operator (TSO) that is determined for a regulatory period with a duration of 5 years is based on the costs incurred at the TSO in the base year (year 3 before the new regulatory period) and that were checked by the regulatory authority. Moreover, an efficiency benchmark is conducted between the TSO and, based on their cost and structure parameters, individual company efficiency values are calculated. Possible inefficiencies are to be rectified over the duration of a regulatory period. Furthermore, the regulatory authority calculates a general sector productivity factor that is consistently applied to all transmission system operators.

The general sector productivity factor for the third regulatory period is 0.49%. Since the BNetzA has not yet determined a final value for the fourth regulatory period, the general sector productivity factor from the third regulatory period was used initially.

At this time, no final individual efficiency score of OGE is calculated by the BNetzA. Therefore the individual efficiency score from the third regulatory period (100 %) was used initially.

The reconciliation begins the year after next after the application was submitted.

Incentive mechanisms specifically for the regulatory account do not exist in the German regulatory system.

Art. 30 (1) b) vii)

Information on the intended use of the auction premium

Auction revenues are booked on the regulatory account in accordance with Article 5 ARegV. This transaction thus develops a tariff-reducing effect in the years in which the regulatory account is reconciled.

In accordance with the explanations of the BNetzA in decision BK9-22/615 (REGENT recalculation 2023), the auction premium already achieved for the year 2023 will, in deviation from this, be used to reduce the tariff, if it is not assumed that the corresponding capacity contracts will be terminated.

Art. 30 (1) c)

Information on transmission and non-transmission tariffs accompanied by the relevant information related to their derivation

As part of the REGENT 2021 decision, the Federal Network Agency has decided the application of the reference price methodology postage stamp in the entry-exit system Trading Hub Europe. According to this, the transmission service revenues are to be divided by the forecasted contracted capacities of the entry and exit points of the calendar year.

Art. 30 (1) c) i)

where applied, commodity-based transmission tariffs referred to in Article 4 (3)

OGE does not apply commodity-based transmission tariffs.

Art. 30 (1) c) ii)

where applied, non-transmission tariffs for non-transmission services referred to in Article 4 (4)

According to the decision of the FNA (BK9-17/609 (Festlegung ‘INKA’), the non-transmission services are set to metering point operation, metering service, biogas levy according to §20b GasNEV, market area conversion levy according to §19a Abs. 1 EnWG as well as the nomination replacement procedure according to §15 Abs. 3 GasNZV. The non-transmission service fees valid as of 01.01.2022 are published in the price sheets on the website of OGE.

 

Biogas levy calculaction

According to article 6 of the REGENT 2021 decision, the biogas levy is classified as a system service according to § 20b GasNEV. The calculation of the biogas levy is described there as well as in § 7 of the cooperation agreement between the operators of gas supply networks located in Germany from 01.10.2022. According to this, the nationwide total biogas costs of 2023 amounting to 215.5 million € are divided by the nationwide capacity booked or rather ordered from transmission system operators at network connection points to final consumers and grid connection points to downstream network operators, regardless of multipliers or seasonal factors of the year 2023, amounting to 308,640,666 (kWh/h)/a. This results in a biogas levy of 0.6983 €/(kWh/h)/a.

 

Market area conversion levy calculation

According to article 5 of the REGENT 2021 decision, the market area conversion levy is classified as a system service according to § 19a (1) EnWG. The calculation of the market area conversion charge is described there as well as in § 10 of the cooperation agreement between the operators of gas supply networks located in Germany from 01.10.2022. According to this, the nationwide conversion costs of the year 2023 amounting to 232.9 million € are divided by the nationwide capacity booked or rather ordered from transmission system operators at grid connection points to final consumers and grid connection points to downstream grid operators, regardless of multipliers or seasonal factors of the year 2023, amounting to 308,640,666 (kWh/h)/a. This results in a market conversion levy of 0. 7547 €/(kWh/h)/a.

 

Calculation of fees for metering service and metering point operation

Fees for metering services and metering point operation are charged at the network connection points for which OGE assumes the relevant market roles. The fee for metering point operation includes the measurement. The fee for metering point operation is determined on the basis of a uniform fee for each bookable point plus a fee for each gas meter assigned to the bookable point. Consequently, the fee for metering point operation is calculated as follows:

Fee for metering point operation = fee for bookable point + (fee per gas meter x number of gas meters)

The fee per gas meter and the fee per bookable point are given in the appendix of the price sheet valid at 01.01.2023. The multipliers described for capacity booking with a run-time of less than 1 year do not apply to the fees for metering services and metering point operation. 

Art. 30 (1) c) iii)

the reference prices and other prices applicable
at points other than those referred to in Article 29

The reference prices for exit points of internal orders and network connection points are the same as the postage stamp of the Trading Hub Europe market area. This corresponds to the tariff calculation method which the FNA has determined in the REGENT decision. The reference prices are the result of the sum of forecasted capacity bookings for all entry and exit points as well as the revenue cap and the entry/exit split of the calendar year t. The reference price and other prices can be taken from the current price sheet.

Art. 30 (2) a) i)

Information on transmission tariff changes and trends

The postage stamp of the entry-exit system Trading Hub Europe will increase by 2.52 €/(kWh/h)/a in 2023 compared to the tariff in 2022. This change is based on regular fee adjustments taking into account changes of the input parameters allowed revenues and forecasts of contracted capacity of the transmission system operators involved. The significant changes are due to the geopolitical situation in particular. Thus, a strongly adjusted booking behaviour was assumed in the capacity forecast. In addition, the distortions in the European natural gas market with highly increased energy prices as well as changed flows in the German transmission grid lead to a significant increase in volatile costs (especially driving energy).

Art. 30 (2) a) ii)

The difference in the level of transmission tariffs for the same type of transmission service applicable for the tariff period for which the information is published and for each tariff period within the remainder of the regulatory period

Please see Annex

In order to fulfil the publication requirements, the former approach of the BNetzA (Appendix 5 of REGENT 2021 decision) was continued to forecast the tariffs on an indicative basis. According to this, an increase in the charge would be expected in 2024.

It should be noted that the calculations depend on assumptions that are currently very difficult to forecast. Accordingly, the forecast should be interpreted as merely indicative to fulfil the publication requirements. For inflation, the values stated by the BNetzA in the document "Notes for transmission system operators on the publication of charges pursuant to Articles 29, 31 and 32 of Regulation (EU) No. 2017/460" were used. Furthermore, the value from the third regulatory period was used for the general sectoral productivity factor, as the BNetzA has not yet determined a final value for the fourth regulatory period.

Art. 30 (2) b)

Information about the used tariff model and an explanation how to calculate the transmission tariffs applicable for the prevailing tariff period

Art. 30 (3)

Information about the points excluded from the definition of relevant points

The forecasted booked capacity for the points excluded from the definition of relevant points referred to in point 3.2 (1) a) of Annex I to Regulation No 715/2009 is already included in the capacity forecast according to Art. 30 (1) a) ii).
