Version 0.2 of Parts B and C, based on the SMI Minimum Functional Specification, wasdiscussed by the RWG at its meetings on 8 and 9 October 2009.

Version 0.2A of Parts B and C, recording amendments agreed by the RWG, and issuedraised by the RWG at those meetings, and also recording comments made by the MRG at itsmeeting with RWG leaders on 30 October 2009, was tabled at the RWG meetings held on 9and 10 November 2009.

Version 0.2AA, of Parts B and C, records the BRWG responses to issues raised by the RWG.

Version 0.3 of Parts B and C, based on the SMI Minimum Functionality Specification V0.22,was discussed by the RWG at its meeting on 8 December 2009.

Version 0.4 of Parts B and C based on the SMI Minimum Functionality Specification V0.24,was discussed by the RWG at its meeting on 10 March 2010.

This Version 0.5 of Parts B and C reflects the comments of the RWG at its March meeting, as

well as further amendments to reflect the SMI Minimum Functionality Specification V0.25.

This drafting assumes the SMI Minimum Functionality Specification, as described in Part B,

Rule A, is regulated as a separate clause or schedule to Chapter 9 the Rules, placed to have

a relationship with the Transitional Rule to be made by the Minister under the NEL. This is

the best architecture because the prescription of ‘required smart metering infrastructure’, like

the Transitional Rule, is relevant only to the making of a Ministerial roll out determination (a

’mandate’) and is not relevant to the ongoing operation of Chapter 7 of the Rules..

To discussed by RWG at its April meeting.

In a discussion of Rule B – Switching, Rule C – Supply Capacity Control, Rule D – HAN

Interface Standard and Rule E – Event Recording, at its March 2010 meeting, the RWG

proposed that these Rules needed to be regulated but were too detailed to be included in

NER Chapter 7. Instead, they should be incorporated in appropriate NEM Procedures.

To discussed by RWG at its April meeting. Is 'level of detail' the only criteria for determining

whether these Rules should be in the NEM Procedures (see Regulatory Architecture Paper)?

If these Rules are to be in the NEM Procedures which procedure(s)? Does chapter 7 have to

be amended to provide a head of power for the making of these procedures?

The RWG also agreed to include commentary in the final version of this document,

appropriately referencing the corresponding provisions of the SMI Minimum Functionality

Specification. Note that the references in square brackets refer to the corresponding provision

of SMI Functionality Specification V0.25.

Chapter 10 of the NER (as amended by AEMO proposed Rules changesdated 9 July 2009)

accumulated energy data

The data that results from the measurement of the flow of electricity in a powerconductor where the data represents a period in excess of a trading interval.Accumulated energy data is held in the metering installation. The measurement iscarried out at a metering point.

accumulated metering data

The accumulated energy data, once collected from a metering installation, isaccumulated metering data. Accumulated metering data is held in a metering dataservices database.

active energy

A measure of electrical energy flow, being the time integral of the product of voltageand the in-phase component of current flow across a connection point, expressed inwatt hour (Wh).

active power

The rate at which active energy is transferred.

Australian Standard (AS)

The most recent edition of a standard publication by Standards Australia(Standards Association of Australia).

communications interface

The modem and other devices and processes that facilitate the connection betweenthe metering installation and the telecommunications network for the purpose of theremote acquisition of metering data.

energy

Active energy and/or reactive energy.

energy data

Interval energy data or accumulated energy data.

interval energy data

The data that results from the measurement of the flow of electricity in a powerconductor where the data is prepared and recorded by the metering installation inintervals which correspond to a trading interval or are sub-multiples of a tradinginterval. Interval energy data is held in the metering installation.

interval metering data

The interval energy data, once collected from a metering installation, is intervalmetering data. Interval metering data is held in a metering data services database.

load

A connection point or defined set of connections points at which electrical power isdelivered to a person or to another network or the amount of electrical powerdelivered at a defined instant at a connection point, or aggregated over a defined setof connection points.

measurement element

An energy measuring component which converts the flow of electricity in a powerconductor into an electronic signal and / or a mechanically recorded electrical

meter

A device complying with Australian Standards which measures and records theproduction or consumption of electrical energy.

metering data

Accumulated metering data, interval metering data, calculated metering data,substituted metering data, estimated metering data and check metering data.

metering data services

The services that involve the collection, processing, storage and delivery ofmetering data and the management of NMI Standing Data and information fromthe metering register in accordance with the Rules.

metering data services database

The database established and maintained by the Metering Data Provider that holdsthe metering data, NMI Standing Data and information from the metering registerrelating to each metering installation for which the responsible person has engagedthe Metering Data Provider to provide metering data services.

metering installation

The assembly of components including the instrument transformer, if any,measurement element(s) and processes, if any, recording and display equipment,communications interface, if any, that are controlled for the purpose of metrology andwhich lie between the metering point(s) and the point at or near the metering point(s)where the energy data is made available for collection.

[Note:

(1) The assembly of components may include the combination of severalmetering points to derive the metering data for a connection point.

(2) The metering installation must be classified as being for revenuepurposes and/or as a check metering installation.

(3) An unmetered connection point in accordance with schedule 7.2 doesnot require a meter; it is nevertheless considered as having ametering installation.

(3) The metering installation and related responsibilities are shown as aschematic in schedule 7.1.]

metering point

The point of physical connection in the device measuring the current in the power conductor.

reactive energy

A measure, in varhour (varh), of the alternating exchange of stored energy ininductors and capacitors, which is the time-integral of the product of voltage and theout-of-phase component of current flow across a connection point.

remote acquisition

The acquisition of interval metering data from a metering installation, where atelecommunications network transmits the metering data from the communicationsinterface at site of the metering point to the metering data services database, and:

(a) does not, at any time, require the presence of a person at, or near,the interval meter for the purposes of data collection or dataverification (whether this occurs manually as a walk-by reading orthrough the use of a vehicle as a close proximity drive-by reading),and

(b) remote acquisition includes but is not limited to methods that transmitmetering data via:

(1) fixed-line telephone (‘direct dial-up’);

(2) satellite;

(3) the internet;

(4) wireless or radio, including mobile telephone networks;

(5) power line carrier; or

(6) any other equivalent technology.
