Establishing the Registry
38. Establishment of Registry
The registry operator must establish, operate and maintain the registry so as to meet the requirements of these rules.
39. Purpose of Registry
39.1 The purpose of the registry is –
39.2 To facilitate efficient and accurate switching of retailers by consumers; and
39.3 To provide an authoritative database of current and historical information on all ICP parameters, to facilitate accurate billing of consumers and allocation of charges to retailers; and
39.4 To provide a mechanism by which the accuracy and timeliness of information provided in relation to an ICP is controlled and recorded.
40. Requirements of Registry
The registry must –
40.1 Comply with, and perform in accordance with, the registry specification; and
40.2 Fulfil the purpose of the registry as set out in rule 39; and
40.3 Subject to the validation requirements set out in these rules, accept the information and notices referred to in these rules; and
40.4 Maintain a complete audit trail for all information and notices accepted in accordance with these rules; and
40.5 Maintain records that enable allocation and reconciliation of energy charges, line charges and metering charges between retailers; and
40.6 Facilitate switches in accordance with these rules; and
40.7 Otherwise perform in accordance with the requirements of these rules.
41. Initial Population of Registry
