The electronic message standard developed by EASEE-gas
How it all started
In 1983, four major European companies, Distrigas (Belgium), Gaz de France (France), Ruhrgas (Germany) and Gasunie (The Netherlands), agreed on a standard way for sending and receiving operational data and messages between the dispatching centres. This document was called the GASNET-Protocol. Shortly thereafter, another 10 companies also started using this protocol for their data exchange. At the end of 1995 one of the users, Statoil (Norway), experienced some problems due to high numbers of messages and decided to look for a more international standard for communication. In May 1996 a Workgroup was formed (now called EDIG@S Working Group), in which Statoil and each of the original owners of the protocol were represented by one member. The first goal of this Working Group was to make an inventory of all the messages used, to collect them and to choose an international EDI standard. The result of this inventory and bundling are what are called message-groups. Each message-group is a collection of a number of messages of the same type, e.g. all the request messages. For each message-group a matrix was developed containing all the fields of the messages in that group. This matrix made it possible to define all the messages within a message-group. At the end of 1996, EDIFACT was chosen as the international standard to be used in the future. The EDIG@S Working Group, selected EDS as an EDI consultant to provide support in migrating the telex-based messages into EDI messages. The EDI messages provided the following advantages:
- Reduced the number of different messages used;
- Achieved a more efficient and more flexible way of handling the dispatching activities;
- Allowed for a faster reaction to a changed working environment.
The EDI standard selected for those messages was the UN/EDIFACT standard, but since EDIG@S version 4, the EDIG@S Working Group introduced the XML standard. EDIG@S version 5.1 was released in December 2013.
EDIG@S has become the de facto standard used in the exchange of commercial information between traders & shippers, TSOs, DSOs and producers involved in the European gas supply chain. It is also included in the Network Code for Interoperability and Data Exchange Rules as the data format solution for common data exchanges.

EDIG@S Workshop in Brussels on 22 October 2014
EASEE-gas hosted a workshop in Brussels to present the latest version of EDIG@S (see press release here).
The event provided participants with a detailed overview of the EDIG@S messages and how they are developed, for instance, on the basis of the Business Requirement Specification (BRS) of ENTSOG. The different sessions outlined various topics such as: Common Network Operation Tools (CNOT) for data exchange; Message Implementation Guideline (MIG) of EASEE-gas, based on the BRS Nomination and Matching Process; the REMIT (Regulation on Energy Market Integrity and Transparency) process and timeline; and a case study presentation on the Single Sided (SSN) and Double Sided Nomination (DSN).
