EIEP1 - Detailed ICP billing and volume information
- traders to provide billing and volume information to distributors at an ICP level to enable distributors to invoice fixed and variable network charges, meet the distributor’s network planning, pricing design, and regulatory information disclosure reporting requirements, and provide information to the extended reserve manager.
- distributors to provide information to traders to support their invoices for network charges, and to enable traders to reconcile the network charges at a detailed level.
EIEP2 - Aggregated billing and volume information
- traders to provide aggregated EIEP1 billing and volume information to distributors
- distributors to provide aggregated information to traders that supports the distributor’s invoice and enables reconciliation of the distributor’s network charges covered by the file.
EIEP3 - Half hour metering information
- traders to provide half hour metering information to distributors at an ICP level to enable distributors to invoice traders for fixed and variable network charges associated with ICPs where half hour metering information is required. This meets the distributor’s network planning, pricing design, and regulatory information disclosure requirements, and provides information to the extended reserve manager.
- embedded network owners to provide half hour metering information to the parent network owner for LE (embedded network gateway) ICPs.
EIEP5A - Planned service interruptions
EIEP5A has been made mandatory but does not have an effective date yet.
EIEP5A allows distributors to provide planned service interruption information to traders to enable traders to record details in their customer information systems and notify affected customers where required to do so by the relevant use of system agreement.
EIEP5A - Planned service interruptions – not in force, date to be advised.
EIEP12 - Delivery price change notification
EIEP12 applies when a distributor, who does not send accounts for network services to consumers directly, notifies traders of changes to its delivery prices, including by introducing or removing 1 or more delivery prices, for ICPs which have category 1 or 2 metering installations.
Distributors are also required to provide EIEP12 to the Authority.
EIEP13A – Detailed electricity consumption information for consumers (half hour and non-half hour)
EIEP13A 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.

EIEP13B – Summary consumption information
EIEP13B 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
EIEP13C 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 EIEP13A, EIEP13B 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.
