1. Scope of application, and distinction between control energy and balancing energy

1.1 Scope of application The following provisions regulate the organisation of balancing energy management in the Eastern distribution area.

1.2 Distinction between control energy and balancing energy Balancing energy Section 7(1)(2) Natural Gas Act defines balancing energy as the difference between injections and withdrawals by a balance group during a defined metering period, where the quantity of energy per measurement period may be either metered or calculated.

Control energy Section 7(1)(54) Natural Gas Act defines control energy as energy required for the shortterm compensation of pressure variations in the system which occur within a given period.

2. Assessment of the required capacity The distribution area manager (DAM) for the Eastern distribution area shall assess the capacity levels required to compensate for the anticipated imbalance between the injections and withdrawals of all balance groups (“BGs”) in the distribution area sufficiently to maintain stability in the distribution area.

Taking into consideration any existing contracts for reserve capacity concluded for the purpose of providing system services, the DAM shall inform the balance group coordinator (“BGC”) of the additional capacity required, broken down into injection and withdrawal capacity. Balancing energy supply security in the Eastern distribution area may be assured by appointing market makers which undertake to submit bids for given periods.

3. Use of linepack, OBAs and interconnection point agreements

The distribution area manager may use linepack in the distribution area and, subject to the prior agreement of the market area manager, that in the transmission pipelines, both to balance short-term pressure fluctuations in the distribution area and to bridge the period up to the physical settlement of its balancing energy call-offs at the virtual trading point.

–  –  –

Please note that only the German version of this contract is binding. The English translation is not binding and is provided solely for information purposes. All liability on the part of the balance group coordinator for any deviations in content or mistranslations is excluded.





The distribution area manager maintains an account for linepack use in the distribution area.

The distribution area manager undertakes, in consultation with the market area manager, to draw down the net balances on the OBA accounts in a timely manner by employing the linepack in the distribution area or balancing energy call-offs on the gas exchange at the virtual trading point or from the merit order list. The provision of reserve control energy and use of control energy under interconnection point agreements is recorded in accordance with the arrangements specified by those agreements. In the event the event that tolerance thresholds are exceeded, the net balances of the OBA accounts shall be drawn down in a timely manner. Control energy procured under interconnection point agreements that have been concluded for the distribution area is recorded in the accounts set up by the balance group coordinator for this purpose. In the event that control energy procured under interconnection point agreements is obtained on the gas exchange at the virtual trading point or by means of merit order list call-offs, this shall be on behalf of and for the account of the balance group coordinator.

4. Call-offs from the virtual trading point Balancing energy must be procured primarily by way of trading in standardised products in the meaning of section 33(1) GMMO-VO [Gas Market Model Order] on the gas exchange at the virtual trading point.

The DAM calculates the actual and forecast net balance for the distribution area on an hourly basis, and primarily procures the physical balancing energy needed for disturbance free control of the distribution area on the gas exchange at the virtual trading point on behalf of and for the account of the balance group coordinator.

5. Balancing energy offers and call-offs from the merit order list In the event that no offers have been made on the gas exchange at the virtual trading point, or the DAM requires locational or temporal products to safeguard the disturbance free operation of the distribution network, it may call off bids from the merit order list.

Balancing energy suppliers shall ensure that the energy offered by it can be injected into the distribution area system at the specified rate and at the specified injection and withdrawal points 30 (thirty) minutes after the call-off by the DAM, and is actually withdrawn at the specified rate.

The DAM calls off the required quantity of balancing energy on behalf of and for the account of the BGC. The DAM is responsible for ensuring that the balancing energy it calls off is actually injected into and withdrawn from the system.

–  –  –

Please note that only the German version of this contract is binding. The English translation is not binding and is provided solely for information purposes. All liability on the part of the balance group coordinator for any deviations in content or mistranslations is excluded.

Call-offs are for one-hour periods and begin on the hour.

–  –  –

Balance group members which have completed the registration process for balancing energy suppliers (a description of the process is posted on the BGC’s website) are eligible to offer balancing energy, subject to the approval of their balance group representatives (“BGRs”), in accordance with the AB-BGV [General terms and conditions of balance group representatives] as amended. In the course of the registration process the balance group members in question must demonstrate that they have access to appropriate flexibility tools, e.g. ability to move gas into and out of storage at short notice, availabilities at the market area’s entry/exit points, and volume controllable consumers with online metering and data transmission to the DAM. Balancing energy suppliers must notify the BGC of the entry/exit points where they will offer balancing energy.

The BGC will notify the DAM of any changes in the list of registered balancing energy suppliers by sending it an updated list.

Balancing energy may be offered no earlier than 2 (two) working days after the supplier has registered with the BGC and the DAM has set up balancing energy entry/exit points.

The supplier undertakes to inject/withdraw the promised quantity of gas into/from the distribution area upon call-off of the balancing energy. In the event of partial or complete nonfulfilment of a call-off settlement between the BGC and the supplier will be adjusted to the actual quantity of energy delivered/withdrawn.

In the event of non-performance, section 5.4 below shall apply.

–  –  –

Balancing energy suppliers may only submit offers via the BGC’s online platform, in accordance with the conditions of supply and procurement set out below. Otherwise the GTC BGC shall apply.

Balancing energy suppliers shall submit offers to the BGC. The offers must include the balance group identification code assigned by the MAM, the hour to which the offer applies, the amount of reserve capacity, the energy price, and the injection or withdrawal point. Each balancing energy supplier may submit offers with a minimum duration of 1 (one) hour and a minimum capacity of 1 (one) MWh/h. The offers must be at fixed prices.

–  –  –

Please note that only the German version of this contract is binding. The English translation is not binding and is provided solely for information purposes. All liability on the part of the balance group coordinator for any deviations in content or mistranslations is excluded.

Offers for the following gas day must be submitted by 16.00 (market close). Offers for Saturdays, Sundays, and public holidays as well as the following working days must be submitted by 16.00 on the preceding working day. Offers become binding at the market close, after which they may not be modified or withdrawn by balancing energy suppliers. Under exceptional circumstances constituting reasonable grounds, such as technical problems, time pressures owing to the coincidence of weekends and public holidays, or the need to take action in response to a lack of offers, the BGC may, after notifying market participants, defer the market close at short notice.

Should the DAM deem the balancing energy bids placed to be insufficient, it will immediately notify the BGC of same, including the reasons for reaching this conclusion.

The BGC will then reopen the market, determine the new market close and notify all balancing energy suppliers. This notification by the BGC will serve as an invitation to the balancing energy suppliers to offer further quantities in addition to the binding offers made in accordance with the above paragraphs.

The BGC shall keep the market open round the clock for the submission of offers at the request of the DAM. In this case the BGC shall inform market participants in advance that the market will remain open continuously. In the event of continuous market opening the offers shall be transmitted to the DAM at specific times determined and published by the BGC (market close). Offers submitted up to these points in time may no longer be modified or withdrawn.

The BGC ranks the offers, broken down by injection and withdrawal, on the basis of the specified energy prices (“merit order list”). If the prices offered are identical offers of larger quantities of energy take precedence. If both the price and quantity are identical, the ranking is determined by the time at which the bids are received.

The BGC will assign a unique code to each offer.

–  –  –

The BGC shall forward the merit order list to the DAM immediately after the market close, and in the case of continuous market opening at the time specified and published by the BGC. The DAM shall then call off the required bids for injection/withdrawal of balancing energy from the suppliers in accordance with the merit order list. The DAM is entitled to call off a minimum of 1 MWh/h from a given offer, rising in steps of 1 MWh/h until the capacity offered has been called off in full.

–  –  –

Please note that only the German version of this contract is binding. The English translation is not binding and is provided solely for information purposes. All liability on the part of the balance group coordinator for any deviations in content or mistranslations is excluded.

The DAM is obliged to observe the merit order list. Should this be impossible due to congestion on the pipeline network or technical faults, and normal system control and balancing

energy management methods are insufficient to maintain system stability, the DAM is entitled to take the following action:

1. suspension of balancing energy call-off in accordance with the merit order list;

2. simultaneous call-off of balancing energy supply and procurement offers, with the option of recourse to offers with different locations to those stated.
