ETRM-Interface Impementation Guide
This guide aims to help with the implementation of an automatic interface between dispoGas and your ETRM (or via a Middleware Solution). It describes the business cases involved, the dispoGas API endpoints and describes the expected dataflows in detail.
Business Processes
dispoGas can be used for the following business processes (roughly following the EASEE Gas CBP 2018-001-02 Harmonised Gas Role Model - Business Process perspective.
Send VTP Nominations
A nomination at a virtual trading point to the responsible Area Coordinator indicate the traded quantities with other counterparties.
Send Gas Flow Nominations
A nomination to a Transport, Storage or LNG System Operator of the flow that should inject into or withdraw from the system.
Send (or receive) B2B nominations
A nomination to a counterparty, indicating the requested utilization of a flexible (swing) contract.
Data Transfer to dispoGas
Typically, the sequence of any of these processes is as following (Middleware is optional and could also be solved in the ETRM itself):
Data Transfer from dispoGas
The transfer from dispoGas to the ETRM system is only required for the processes
- Send Gas Flow Nominations
- Send (or receive) B2B nominations
and should follow the following sequence diagram.
It is important, that there is an 1:1 relationship between the dispoGas Nomination Track and the ETRM trade or timeseries.
