EIEP 1 - Detail ICP billing and volume information

EIEP1 allows traders to provide billing and volume information to distributors at an ICP level where the distributor has specified the requirement for non-half hour volumes for an ICP. The protocol supports the invoicing of fixed and variable line charges and/or meeting the distributor's operational information requirements. It also allows distributors to provide information to traders to support line charge invoices and traders to reconcile the distributor’s line charges. EIEP 1 can be used for reporting both half hour and non-half hour data.

EIEP 2 - Aggregated volume information

EIEP2 allows traders to provide aggregated EIEP 1 billing and volume information to distributors. It can also be used by distributors to provide information to traders that supports the distributor’s invoice and assists with reconciliation of the distributor’s charges.

EIEP 3 - Half hour metering information

EIEP3 allows traders to provide billing and volume information to distributors at an ICP level where the distributor has specified the requirement for half hour data for an ICP. The protocol supports the invoicing of fixed and variable line charges and/or meeting the distributor's operational information requirements. It also allows distributors to provide information to traders to support line charge invoices and traders to reconcile the distributor’s line charges. This protocol provides metered half hour data by ICP. This format can accommodate multiple ICPs in a single file or an individual file per ICP.

EIEP 12 - Tariff rate change information

EIEP 12 applies when a distributor who does not send accounts for line function services to consumers directly changes its tariff rates, including by introducing or removing 1 or more tariff rates, for consumers who have category 1 metering installations or category 2 metering installations.

EIEP 13A – Detailed electricity consumption information for consumers (half hour and non-half hour)

EIEP 13A allows retailers to provide detailed consumption information to consumers or their authorised agents. Retailers will provide detailed half hour consumption information, as well as a consumer’s non-half hour consumption information, where this information has been used by the retailer to either calculate the amount of electricity consumed by the consumer at each ICP or provide any service to the consumer.

 EIEP 13B – Summary consumption information

EIEP 13B allows retailers to provide summary consumption information to consumers or their authorised agents. Retailers will provide the consumer’s billed consumption information that the retailer has supplied to the consumer (summarised non-half hour consumption information).

 EIEP 13C – Electronic request format for EIEP 13A or EIEP 13B

EIEP 13C allows a consumer’s authorised agent to request consumption information from a retailer. The agent may request consumption information for consumers and formatted using either EIEP 13A, EIEP 13B or both.

Note: if you are using EIEP 13A, 13B, or 13C, you are also required to follow the ‘Procedures - Requests for consumer consumption information’. This document is available on the access to consumption data webpage.
