Common Arrangements for Gas (CAG)

The Common Arrangements for Gas (CAG) project commenced in 2008 between Northern Ireland and Ireland. It aimed to harmonise technical operations of the gas transmission networks in both jurisdictions.

The CAG project has now been superseded by EU internal gas market developments. The EU agenda requires the implementation, within specified timeframes, of binding EU gas network codes.

A network code is a set of rights and obligations that apply to parties operating in the European gas markets.

The Commission for Regulation of Utilities (CRU) and the system operators are working with their EU counterparts in the development and implementation of these new gas network codes.

Once adopted, the codes will apply across Europe in the same way as an EU Regulation.
