The Code of Operations governs the relationship between the Transporter and the Shippers on the transportation (transmission and distribution) network. By signing Framework Agreements, Shippers accept the terms of the Code of Operations.
The initial Code of Operations was introduced in June 1999 governing the operation of the transmission network. Version 3 of the Code was introduced in November 2003 and was in place until March 2005.
In February 2005, the CER approved the implementation of a new Code of Operations which governs the rules for both the transmission and the distribution network. These rules became effective on April 1st 2005.
The Code is comprised of sections outlining the general principles of the Code, regulatory compliance, the capacity arrangements (both entry and exit), the nomination and allocation arrangements, balancing, Shipper registration, gas specification and quality, as well as the various sections on congestion management, legal and general.
