1.3.1 Storage entry point

In the capacity view of the entry point the following information is for every storage dis-

played:

- Hourly profile: Entry nomination

- Hourly profile: Capacities from package reservations (identical view for entry and exit

point)

- Daily profile: Level of the working gas account (identical view for entry and exit point)

- Daily profile: Maximal stand for the working gas account (package reservations, iden-

tical view for entry and exit point)

Picture 6: Storage entry point (Capacity View)


11/27



1.3.2 Storage exit point

The button in the top of the screen switches between 2 different viewsthe Capacity-View

(CAP)and the Energy-Data-Management-View (EDM).

In the EDM-View the details for the equipment information with counter mechanism are set

for the installation. This is used to manage the following data:

- Formula profile (hourly values): Sum for the exit nomination of exit settlement

- Profiles for metering (preliminary and finally) of entry nomination for entry settle-

ment

- Profile for calorific values for entry storage into the network

In the view of the capacity of the exit point, for every transport customer the following in-

formation will be shown:

- Hourly profile: Exit nomination

- Hourly profile: Capacities from package reservations

- Daily profile: Stand of the working gas account (identical for entry and exit point)

- Daily profile: Maximal stand for working gas account (from package reservations,

identical for entry and exit point)

1.3.3 Operating Balancing Agreement

The Operating Balancing Agreement (OBA) is an agreement between an operator at an entry

and the nominator of non-assignable residual amounts on the distribution.

During the nomination process, the divergences between the target and the physical memo-

ry on the operating mode of the operator control account (OBA) are posted. For this purpose


12/27



an "Operating Balancing Agreement" has to be signed between the storage facility operator

and the network operator. The goal is a balanced account.

A negative balance of the network operators control account means a shortage of the net

against the storage, while a positive account balance an exceed of the networks against the

storage represents. Thereby saving on the nomination will be deducted from the measured

value, while deducted from the measured value of the nomination.

Saving of Storage

Nomination 100.000 kWh

Measurement 90.000 kWhShortage of storage OBA -10.000 kWh


Measurement 110.000 kWh

Exceed of storage OBA +10.000 kWh

Removal of storage



Shortage of removal OBA +10.000 kWh



Exceed of removal OBA -10.000 kWh

Table 2: Example for the determination of the OBA balance

In the OBA agreement, the limit values for the network operators control account are de-

fined and how to respond to higher limits is described, too.

The parties agree that a balance account (network operators control account), if technically

possible, is the major goal and the differences between target nomination and physi-

cal behaviour of the storage are supervised by hourly measured values.

The presentation of the OBA account is in the coregas Gasstation Display.

2 Capacity management

coregas for TSO has the possibility to check for free capacities and therefore it crosschecksthe numbers of connected pipelines. The capacity check is based on available and market

capable transport capacities of the segments of the transport system.

coregas for TSO has the ability to control the network-capacity for different transport sce-

narios (grid points, workload, flow direction, etc.).

coregas for TSO supports the control of the requested transport capacities versus the availa-

ble capacities regarding to the different workload scenarios short, middle and long range

intervals.

coregas for TSO has functionalities for all transport routes, transport section routes, trans-

port sub section routes and capacity workload scenarios to collect and maintain at least data

for:

Unique identifier of the transport segments

Technical attributes of the transport segments

Unique identifier of the transport sub-segments based on a transport segment in

an n: 1 relationship

Technical attributes of the transport sub-segments (e.g. basic capacity)

Unique identifier for load scenarios

Technical attributes for load scenarios

coregas for TSO maps the various network topologies and network levels with the appropri-

ate network points relationship. Each of the net available capacity is shown.

The network points are connected with all necessary segments for showing all relations be-

tween the partially overlapping transport relations and all network points (which are listed in

the transport contract and the internet).

The path from an interconnection point to another (entry/exit) will be shown in coregas for

TSO through the entry to exit point matrix.


15/27



coregas for TSO identifies all possible transport paths and sub paths to a particular transport,

the results from a point-to-point service provided for clients booking.

To check the possible requested transport capacities, coregas for TSO calculates based on

booked capacities and reserved capacities possible free capacities for single sub path and

network points.

For further processing, the following data of coregas for TSO is considered:

Take-over or entry point

Interconnection or entry point

Load-scenario

Fixed / interruptible

Start date of the transport service

End date of transport service

Requested capacity profile (m3/h)

Gas pressure (entry and exit)

Gas quality

coregas for TSO shows the results of previously executed controlled capacities in a tabular

structure:

Entry-/exit point (characteristically classification)

Transport path (characteristically classification)

Transport segment (characteristically classification)

Minimal capacity

Current maximum capacity

Nominated fixed capacity

Available capacity

Nominated interruptible capacity

A list of all transport segments and sub segments (all assigned, provisionally assigned and

available capacities) will be processed.

coregas for TSO correlates transport segments and network points with their summed allo-

cated capacity. If a capacity within a transport path has a state reserved / available o r


16/27



booked assigned, coregas for TSO will regard this in further processes as not changeable.

Additionally the state effectively reserved can be given for further capacity planning.

The booking process or the reservation of transport capacities can be revoked. Therefore the

state of the capacity must be released from reserved/offered, booked or requested to free

and the quantities of the available capacities must be checked.

If enough capacities are available for a specific request, the state will be changed to YES.

In the event that one or more entry-exit capacities and transport segments can be used for

this interrupt, the availability state will be set to interruptible.

In all other cases coregas for TSO will set the available state on NO. In order to hold the

resulting rejection of the requested capacity for a later revision, coregas for TSO can save

capacity situations (e.g. transport quantity, etc.).

coregas for TSOcalculates future transport requests based on the net structure. Therefore

coregas for TSO creates offer/ request scenarios for nodes and transport segments based on

net segments.

The load scenario monitor displays the flow situations or a virtual flow situation within the

pipelines and identifies the points where a capacity may be interrupted because of the fact

that it runs short.

Each capacity contract is assigned to a corresponding capacity load scenario. Capacity checks

are performed against corresponding load scenarios. A capacity overload from the load sce-

nario to the contract has to be avoided.

coregas for TSO is able to analyse the capacity request based on offer/ request scenarios and

current overload in the net.

2.2 Allocation preparation

coregas for TSO provides the following possibilities in preparation of an allocation which is

processed later:

Determination of capacity settlement for a certain time series

Check and Reservation of capacity requests

Calculation of free and booked capacities

Validation of capacity by nomination limits

Cyclic update of time series

2.3 Seamless integration in SAP IS-U

Integration in the SAP IS-U/EDM data model is given about the use of the SAP IS-U installa-

tions and point of delivery.

2.4 Event Logging

Separate log documents are written for all the events that result in the calculation and

processing of capacity relevant objects in coregas for TSO.

3 Nomination- and allocation management

3.1 Allocation effective nomination management

The nomination management includes all nominations compared to the corresponding op-

erators. The nomination must be made by all market partners e.g. in kWh indicating alloca-

tion number on an hourly basis.

Generally it could be nominated:

All inputs into the market area as border crossing, crossing the market area, storage

exit, national production, feeding biogas, LPG mixing station exit.

All the offtake from the market area as border crossing, crossing the market area,

storage entry,

Transfer of gas quantities at trading or balancing points.

3.2 Inbound processing of nomination

The following functionalities based on the Edig@s-Market-Communication-Formats are sup-

ported (a detailed overview of all supported formats is given within chapter 4):

The following activities for example are supported:

Receive a NOMINT message

Acknowledgement of receipts

Processing a NOMRES message

Matching request as s DELROD message

Matching answer as a DELRES message

Archiving of the acknowledgement

Logging

Profile storage with corresponding allocation

Configuration of the nomination time limits on the interconnection point and suppli-

er level

Flexible configuration and implementation of correction procedures for each inter-

connection point and supplier

Automated replacement values for missing nominations

3.2.1 Processing of incoming IDocs

The reception of messages of the format NOMINT is done automatically through a specially

defined IDoc format. The used IDoc type will be configured in the customizing. Apart fromthe acknowledgement of receipts per NOMRES is the confirmation or correction of nomi-

nation possible. The following figure illustrates a nomination and a capacity for a grid con-

nection point within the graphical display:

4 Market communication

coregas for TSO gives the user the possibility to automatically take part to the market com-

munication with other market members. Therefore coregas for TSO has the special Edig@s -

formats integrated, as they are used in a lot of european countries.

NOMINT / NOMRES

The message types NOMINT and NOMRES can be used for the exchange of nominations

within the gas market. If e.g. a transport customer processes a nomination at a virtual trad-

ing point a message of the type NOMINT is used and answered by a message of the type

NOMRES. Within this answer will the asked amount of energy be accepted or an adjustmentto the original nomination will be send.

The product coregas for TSO offers the possibility to receive to process and to send messag-

es of the formats NOMINT and NOMRES.

Appendix A:

Example for the determination of a technical quantity

In the context of the condition quantity revaluation, coregas for TSO provides the opportuni-

ty of the revaluation of the operating volume of a mass of gas into a standardized volume.

The operating pressure of the gas, the gas temperature and the compressibility factor serve

as possible input parameters. The compressibility factor can be calculated according to the

standard procedure of the American Gas Association, which has been described in the report

8 (AGA 8), where the 21 gas components are evaluated.

Replacement Value

In the standard delivery of the SAP IS-U are replacement value procedure already contained.

coregas for TSO contains additional replacement value procedures, which offer optimized

procedures for the replacement value formation particularly for the characteristics of gas

sector. One of these replacement value procedures are the alternative calculation of stan-

dard volume based on the operation volume. This procedure replaces missing profile values

for the AMR (automatic meter reading) if they are not correctly transferred. These values are

calculated in coregas for TSO with help of the operation volume Vo and the S-factor.

The other replacement value procedure which is implemented in coregas for TSO is the re-

taining value procedure. This procedure holds with its assistance replacement values formissing values in the transmission.

Calculation Workbench

The calculation Workbench provides the user the ability to create user-defined formulas

without programming any code for the calculation. For the definition and calculation are no

special privileges in the system necessary.
