The XML interoperability and the Polish Energy Market needs

There are only a few months from the Polish Energy Market openning. This subject, especially in the face of the last political confusion about the natural gas delivery has been a topic of many publications and speeches of politicians during the last months. But, besides this medial outcry, well working and flexible Polish Energy Market, as it is planned, is a very complex problem to solve, and there are many tasks to be done before the 1 July 2007 [1]. In this work the author focuses on the aspects of information flow coordination between the end-users (consumers of energy) and other participants (generators, transmitters, wholesale resellers – the players) of the Polish Energy System. In this article there will be described a concept of two direct electronic data exchange between the energy measure unit located at let’s say “Kowalsky’s” house, and any other computer systems of the player.
