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.

The individual efficiency score of OGE is 100% for the fourth regulatory period. 

110.2 (+7.1 vs. prior year)

(CPI of 2022, § 8 ARegV)

The forecasted revenue from transmission services in 2024 amounts to 1,055,016,732€. 

(1) OGE offers capacity-based tariffs only. Consequently, the share of capacity-based tariffs is 100%.

(2) Entry-Exit-Spilt
33.8 % Entry  
66.2 % Exit

(3) Cross-border-domestic split in entry-exit system:
86.35 % domestic usage (2,399,738,890 €)
13.65 % cross-border usage (379,248,843 €).

In conjunction with Art. 26 NC TAR consultation, the cost allocation test was carried out by the BNetzA. The test results, including an assessment, are published on the website of the Federal Network Agency via REGENT for the market area Trading Hub Europe (BK9-19/610) entry-exit system.

(1) Actual regulated revenues obtained of 2022: 1,251,155,734 €

-       thereof transmission service: 1,049,503,341 €

-       thereof non-transmission service: 201,652,393 €

Aggregated balance of the regulatory account of the closed financial year 2022: -37,557,959 € (shortfall revenues)

Total balance of the regulatory account (net value) until 31.12.2022: +51,051,092 € (excess revenues)

(2) Reconciliation of the regulatory account for the concluded business year 2022 will be determined as of 31.12.2023 and it will be reconciled in equal instalments – including interest payments – over the three calendar years. 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.

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 the information paper for transmission system operators on the publication of tariffs in accordance with Art. 29, 31 and 32 of Regulation (EU) No. 2017/460 ("NC TAR") of 02.06.2023, the auction premium already achieved for the year 2024 that can be forecast on the basis of a best possible estimate, e.g. on the basis of reliable knowledge from previous annual auctions, are used to reduce the tariff.

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.

OGE does not apply commodity-based transmission tariffs.

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 01.01.2024 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 12.08.2022. According to this, the nationwide total biogas costs of 2024 amounting to 254.7 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 2024, amounting to 303,877,893 (kWh/h)/a. This results in a biogas levy of 0.8381 €/(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 12.08.2022. According to this, the nationwide conversion costs of the year 2024 amounting to 203.9 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 2024, amounting to 303,877,893 (kWh/h)/a. This results in a market conversion levy of 0.6711 €/(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 01.01.2024. 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. 

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.

The postage stamp of the entry-exit system Trading Hub Europe will decrease by 0.93 €/(kWh/h)/a in 2024 compared to the tariff in 2023. 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. A significant factor that has contributed to this reduction in tariffs is the lower cost of energy for compressor operation compared to the last calculation now that the previously tense situation on energy markets has eased.

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 2025.

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 information paper for transmission system operators on the publication of tariffs in accordance with Art. 29, 31 and 32 of Regulation (EU) No. 2017/460 ("NC TAR") of 02.06.2023were used. Furthermore, an estimate was made for the general sectoral productivity factor according to Section 9 ARegV by updating the value from the third regulatory period, as the BNetzA has not yet determined a final value for the fourth regulatory period.

Further assumptions on the development of the forecast capacities and the annual development of the permissible revenues can be made directly by the user in the model.

Please see Annex

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).
