The association of European gas network operators, ENTSOG, said Wednesday it had begun work to draw up a code governing capacity allocation mechanisms.
The European code would set out how companies should offer access to space in their transmission pipelines.
ENTSOG is required to deliver the rules within a year, for scrutiny by the new European energy regulator, ACER.
Vittorio Musazzi, ENTSOG's general manager said: "Today we have launched our project plan and held a kick-off session with stakeholders. We need fast feedback from stakeholders to ensure that we are all ready and committed for the upcoming challenges to deliver the first network code."
From March there will be a series of meetings with industry participants to draw up the code and discuss ideas.
Frank Roessler, ENTSOG's capacity subject manager, said: "These interactive sessions will be crucial to establish a network code attracting broad stakeholder support. During the summer we will consult formally upon the network code but early stakeholder involvement will be essential to get a well-formed initial proposal."
ENTSOG is based in Brussels and comprises 32 members from 22 EU countries.
