The purchase, sale and transport of natural gas across the Irish natural gas network is governed by a set of market rules and codes. As the Transporter, Bord Gais Eireann manages these codes which deal with issues such as capacity, balancing, allocations, nominations, measurement and maintenance. The CER regulates the terms and conditions of the codes.
Until July 2003, a “point to point” regime existed in Ireland whereby Shippers would book capacity from a nominated point of entry to a nominated point of exit. This has now been eplaced by an “entry/exit” regime and a new code of operation governing this regime has been adopted.
