After our first project for Eesti Energia on the power markets, we were trusted to automate their natural gas market data exchange based on edig@s messages using the AS4 protocol to communicate with the Common Zone gas platform for Elering and Conexus Baltic Grid. Later the AS4 module was extended towards Gasgrid Finland and Amber Grid in Lithuania. 

Successful interoperability of gas markets across the EU of course requires clear data communications between market actors to ensure proper delivery of gas when and where it is needed. Commission Regulation (EU) 2015/703 introduced a new data exchange protocol, AS4, for natural gas transmission network participants to use for automated data exchange and communication purposes.

AS4 is an open standard for secure data exchange between organizations long trusted in a variety of industries. Shippers who have already implemented data exchange via this protocol have discovered many advantages, and the number of natural gas traders who opt for trading process automation via AS4 in the Baltic States and Finland is rising.
