Electricity information exchange protocols (EIEPs)
Electricity information exchange protocols (EIEPs) provide a set of cost-effective standardised formats for business-to-business information exchanges.
We have recently completed an operational review of EIEPs 1 - 12. The amendments made to the EIEPs, excluding EIEP5A, will come into effect on 1 October 2019. The effective date of EIEP5A will be advised once a second consultation on the delivery mechanisms of the file has occured.
The amended EIEPs are available here. There is a track change and a clean version of each amended EIEP.
The current EIEP are located below.
The EIEPs have been developed and revised over a period of many years, supported and coordinated by us, and informed by industry consultation and a panel of industry representatives called the Standing Data Formats Group.
There are currently 14 different EIEPs, covering a diverse range of electricity information routinely exchanged between traders and distributors, and retailers and third party providers.
EIEPs 13A, 13B and 13C, relating to the request and exchange of consumer consumption information, came into force on 1 February 2016.
EIEPs 1, 2 and 3, relating to the exchange of volume and billing information, are already in force.
EIEP 12, relating to distributor tariff rate change information is already in force.
The remainder of the EIEPs are agreed between industry participants, and retailers and third party providers and not regulated. However we encourage industry participants to use the latest versions of these EIEPs.
The information covered by the EIEPs (and any other information) may be exchanged using the registry’s EIEP exchange hub’s secure file transfer protocol (SFTP). This allows the encrypted exchange of information directly between participants. The registry functional specification has guidance on this method of transmission.
