If you intend to book DZK exit capacity for end-consumers, please choose the DZK-type “RLM” during the application process for new balancing groups in the THE portal. Please assign the corresponding entry capacity to the same balancing group. For bayernets, this is currently only the case for the grid points Schongau and Wacker.
bayernets expects the supplier of power plants to send a binding forecast in the form of a technical offtake notice (TON) in the NOMINT format. The TON must be sent to us by 22:00 CEST/CET on the day before delivery and again should there be any changes regarding the power plant offtake.
In general, you can supply power plants via VTP. However, if there is congestion on the bayernets grid, we will inform the power plant suppliers 4 hours in advance and the supply via VTP will no longer be possible. Subsequently, supply to the power plant using the predefined entry corresponding to the TON becomes mandatory (please check Appendix 1 of the agreement on the cooperation between operators of gas supply networks in Germany Sections 9 and 29b).
In the case that the entry is not sufficient for the power plant (entry < TON), bayernets can interrupt the remaining interruptible part of the DZK capacity. If the interrupted part of the DZK-capacity is still being used by the power plant, we will regard this as capacity exceedance. Furthermore, we may also enforce claims for damages.

Option 2
Transfer of gas between discounted to undiscounted storage accounts according to REGENT 2021
The normal way to initiate such a transaction would be to book capacity back into the market area, plus another capacity back into the storage. Instead of these two bookings, you can also directly transfer the gas within the storage. The total costs consist of the costs for a discounted booking, e.g. for injection (25%) plus the costs for an undiscounted booking, e.g. for withdrawal (100%). In total, the overall costs amount to 125% of the standard capacity at the grid point. For periods from 01st December 2025 onwards, we will offer a 10% discount on these bookings in accordance with the current regulation.
How does the transfer work?
On PRISMA, select the correct capacity at the storage point labelled "Discounted to Undiscounted" or "Undiscounted to Discounted". After booking the capacity, a notification will be sent from PRISMA to bayernets and the storage operator and the charges will be calculated as described above.
Please note the hourly basis of the booking: for example, if you want to transfer 24,000 kWh, you must book 1,000 kWh/h.
The following diagram shows an example of these options for USP Haidach.
Overbooking/overrun is not possible on our grid.
RAG's share in Haidach storage is part of the Haiming 2 RAGES network point.
At the 7-Fields point, we have one physical system (pipeline/meter), but two storage operators: Uniper and RAG Energy Storage. Therefore, when publishing physical flows, it is not possible to differentiate between Uniper and RAG ES, as there is only one shared flow.

All firm capacity products at a specific network point (including DZK) have to be sold-out before in order to activate bookings via over-nomination. A booking via over-nomination is always created at bayernets when the nomination of a balancing group exceeds the booked capacity at this network point and the over-nomination is activated (see link to data platform HP). This system has been in place at bayernets for years. As we are not permitted to treat our customers in a discriminatory manner, we are also not permitted to grant any exceptions.
A DZK capacity can be assigned to a standard balancing group (a non-DZK balancing group).
DZK is considered as firm capacity when the point(s)-to-point(s) criteria of the specific DZK product are met and only a specific transmission path it used. E.g. a DZK exit becomes a firm product when specific entry points are nominated within the same balancing group. In this case, the capacity type of the entry product does not matter – only the resulting entry nominations make the DZK exit product a firm capacity.
However, if the DZK exit nominations exceed the corresponding entry nominations, the exceeding part becomes interruptible.
The same applies vice versa for DZK entry products.
From 01.01.2025 onwards, the storage levy will only apply to RLM and SLP points. No longer to IPs. Storage transports (including cross-border storage transport) were exempted from the storage levy.
Types of use for Regular Balancing group:
An "F" in the sixth position and any number except for 9 in the eighth position (THE0BFH)
- Exit regular end users
- Discounted Exit and Entry to storage facilities
- Entry and Exit Transports at Cross-border points
Types of use for non-discounted storage balancing groups:
An "F" in the sixth position and a 9 in the eighth position (THE0BFH9)
- Exit regular end users
- Undiscounted Entry and Exit to storage facilities
- Entry and Exit Transports at Cross-border points
DZK type:
- RLM: Used for DZK Power plants and therefore DZK power plant balancing group is mandatory.
bayernets has a portal that is available for transport customers and offers them – amongst other options – the possibility to change assignments of capacities to balancing groups. In general active transport customers already have the necessary login information. In case you have no login information yet, please contact bayernets (market@bayernets.de).
