Overview
Gas Information Exchange Protocols (GIEPs) specify standard formats for exchanging gas market information between gas industry participants. For example, GIEPs may be used to exchange consumption data required for calculating network billing charges.
Participants can securely exchange GIEP information through the GIEP Exchange, a Secure File Transfer Protocol (SFTP) service provided by the Gas Registry Operator, Jade Software.
The GIEPs currently in place are not mandated by regulation. They may be incorporated into contractual arrangements, such as Use of System Agreements, as the agreed mechanism for information exchange between parties. Alternatively, they may be used as industry guidelines to support information exchanges where a formal contractual requirement is not in place.
The information exchanged under a GIEP may vary depending on the parties' contractual arrangements and system requirements. GIEP formats provide a common industry framework intended to support consistency across the gas sector.
Protocols
All Gas Information Exchange Protocols (GIEPs) are non-regulated.
Current Protocols
These protocols are currently in effect. They will remain in effect until the relevant future protocols take effect on the dates shown.
Future Protocols
These protocols are not yet in effect. The date shown for each protocol is when it will take effect. Once in effect, it will replace the relevant protocol listed under Current Protocols.
Background
In 2010, Gas Industry Co established the Information Exchange File Formats Working Group to develop and maintain standard file formats and protocols for information exchange under gas market governance arrangements. This work resulted in the development of four Gas Information Exchange Protocols (GIEPs), which were subsequently approved following industry consultation and aligned with equivalent protocols used in the electricity industry.
This resulted in GIEP1, GIEP2, GIEP7 and GIEP8.
In 2025, Gas Industry Co consulted industry participants on a review of the existing GIEPs and the potential introduction of new protocols, driven by the rollout of advanced gas meters, amendments to the Gas Consumer Care Guidelines, and the need to improve alignment with Use of System Agreements between distributors and retailers. The consultation also proposed additional protocols based on established electricity industry practices to support improved information sharing and more efficient business processes.
This resulted in amendments to GIEP1, GEIP2, and GIEP8, and the addition of GIEP4, GIEP5B, GIEP12, GIEP13B and GIEP13C.
