Issue / Comment

It isn’t clear in all scenarios whether ‘FRMP’ is intended to refer to the current FRMP for the connection point or the new FRMP.

The Guidelines appear to address the impacts of meter churn for registered meter sites and does not consider an initial meter churn, i.e. when a customer first moves from nonmarket to market.

This will particularly be an issue for jurisdictions such as Queensland where competition has yet to mature and accordingly, where there are still a high number of initial churns occurring as large customers move from nonmarket to market arrangements.

There are a number of additional scenarios, the timely consideration of which may assist with the management of meter churn issues.For example:

• Checkwith LR/LNSP if remote meter reading and load profile data is installed,

that could facilitate a post meter churn;

•load profile (type 5 meter) may be A installed and the addition of a communications unit would allow the meter to remain in place until the transfer date;

• Atype 5 meter may be programmed and display quantities for ‘basic reads’ to meet tariffs for nonmarket arrangements.For large customers secondary tariffs may be removed at the time of meter churn, making it very difficult to finalise the account;

• Themetering equipment should be returned by the new MPB to the designated location, with details of the removed location NMI, final reads, etc;and

• Finalreadings and date/time of removal of meter equipment need to be communicated to designated persons and data from the new meter supplied to the LR/LNSP up to the transfer date for account finalisation.

Ergon Energy queries whether the new FRMP will have access to the required information regarding the existing relationships and roles for the connection point prior to transfer completion.

Clause

4.4.6 and 4.4.8

4.4.7

Issue / Comment

The intended application of these clauses is unclear. Clause4.4.6 requests consideration of a metrology change post transfer and clause 4.4.8 requests consideration of a meter change prior to transfer.

Ergon Energy believes that:

• Themeaning of ‘same type and form’ requires clarification. Is this intended to refer to the read type of the meter, meter manufacturer, mounting arrangements, or configuration (i.e. number of data channels, interval length, etc)?

•with the comment above on Consistent clause 2.5, this principle may not be appropriate for application in circumstances of initial meter churn.For example, substantial work may be required to convert multiple single phase meters to one polyphase meter, remove unwanted meters or tariffs, etc.

Proposed text

Clarify the intended interaction of clauses 4.4.6 and 4.4.8.

Clarify the meaning of ‘same type and form’.
