[en] What are the domains covered by the works managed by EASEE-Gas and related to inter-operability? What are the progresses made today on the specifications relative to gas quality? What are the rules implemented so far in the European Union to manage the physical fluxes, the secondary market of capacities or the balancing? What are the brakes and how to overcome them? Who is charged for the implementation of the preconized measures? Do gas producers have to comply with the specifications imposed to other gas actors? These are the questions that were debated during this round table by four participants. (J.S.)

[en] This paper gathers 5 presentations given at the 2003 gas congress of Paris about the network management activity. The first presentation presents the point of view of the commission of energy regulation (CRE) about the opening of the gas market, the tariffing of gas network access, the transparency about the available capacities, the opening of the professionals market to competition and the works in progress. The second presentation deals with the evolution of the gas transport activity in Germany. The third presentation presents the EASEE-gas association for the development of common commercial practices in the European gas market. The forth presentation treats of the evolution of the Spanish gas distribution market, while the last presentation presents the evolution of the liquefied petroleum gases (LPG) sector with the example of the supply of Hiddensee island in the Baltic sea.
