2 Introduction 2.1 Background The Smart Metering Steering Committee (NSSC) has produced a Smart Meter Infrastructure that details the minimum functionality to be prescribed for delivery by Meter Providers (MP) in accordance with the Electricity Rules (NER). The NSSC has requested that the Smart Metering Business Requirements Working Group (BRWG) formally request smart meter vendors and smart meter communications network vendors to provide information in relation to the detail prescribed in Smart Metering Infrastructure (SMI F.S.) Version 0.26. 2.2 Objectives There are three objectives for requesting information from vendors: 1. For the Smart Metering Program (NSMP) to confirm that the functional requirements defined in the Smart Metering Infrastructure (SMI F.S.) are clearly understood and unambiguously stated 1 2. For the NSMP to determine cost implications to the smart meter and smart meter communications hardware and software that may be identified due to new requirements over and above the current Victorian Advanced Metering Infrastructure. 3. For the NSMP to consider the relative merits of potential. This will examine the need to separately specify levels for urban, rural and remote areas. It is also considered desirable to examine the impact of specifying Levels well above those outlined in the Victorian AMI specification. Note: This analysis will use the Victorian Advanced Metering Infrastructure as a baseline for both the meter costs and Levels discussions. The SMI has made incremental changes to the functions described in the Victorian AMI specification. Although a single vendor is not precluded from supplying all of the components for the SMI, it is not assumed that a single vendor will supply all the components of the SMI, as such meter functions and communications are presented in different sections. 2.3 Review timetable The NSSC has approved the following timetable for the vendors review: The NSSC reserves the right to independently conduct its own reference checks of your responses. 3 Request For Information 3.1 Smart Meter Configurations There are five potential smart meter configurations defined in the SMI F.S. These are shown in Table 1. For each metering configuration please detail if you offer a solution that meets the minimum requirements of the Victorian AMI and/or the SMIFS. If you do not currently provide a solution meeting the requirements, please detail when you intend to offer a solution meeting the requirements. Table 1: Smart Meter Configurations Ref No. Meter Configuration 1. Single Phase Single Element Meter 2. Single Phase Two Element meter 3. Three Phase Whole Current Meter 4. Three Phase CT connected meter 5. Three Phase CT connected meter supporting external Supply Contactor Intend to provide this configuration 3.2 Smart Meter Hardware Function Requirements Vendor Comments The SMI F.S. provides requirements for 21 functions. These are shown in Table 2 below. The column invites vendors to provide clarification where the stated requirements may lead to uncertainty or ambiguity in the specification. The column provides an opportunity for vendors to outline cost implications over and above meter hardware and software meeting the current Victorian AMI. Please note that the NSMP only requires the cost difference comparing the SMI F.S. to the Victorian AMI Requirements. For those items for which there is a material cost implication, please highlight the specific requirement that is impacting the cost. Vendors are invited to suggest changes to the wording which would provide similar functionality but at a lower cost. 31 May 2010: Issue RFI to vendors 7 June 2010: Vendors to lodge questions 10 June 2010: Vendors Briefing 10:00 am to 12:00 pm (PwC Offices, Freshwater Place, Melbourne) briefing session and answer any questions (NSMP overview, RFI objectives and answer vendor questions) 25 June 2010: RFI submissions due (20 business days from 31 May 2010) 2.4 Independent Validation of RFI Responses Please provide a means that the NSSC can employ to independently validate your responses to this RFI. 1 There is also a suggestion that it is desirable to capture recommendations and other comments for each function File Name: NSMP_SMI_VendorsRFI_V1.0.doc Page 3 of 37

Table 2: Smart Meter Requirements Section Implications for meter cost Vendor Comments For example how to meet functionality without increasing cost 7.1.1 Measurement and Recording 7.2.1 Remote Acquisition 7.3.1 Local Acquisition 7.4.1 Visual Display and Indicators on Meter 7.5.1 Meter Clock Synchronisation 7.6.1 Load Management through a Controlled Load Contactor 7.7.1 Supply Contactor Operation 7.8.1 Supply Capacity Control 7.9.1 Home Area Network using Open Standard 7.10.1 Quality of Supply and Other Event Recording 7.11.1 Meter Loss of Supply Detection 7.12.1 Remote Meter Service Checking 7.13.1 Meter Settings Reconfiguration 7.14.1 Software Upgrades 7.15.1 Plug and Play Device Commissioning 7.16.1 Communications and Data Security 7.17.1 Tamper Detection 7.18.1 Interoperability for meters/devices at Application Layer 7.19.1 Hardware Component Interoperability 7.20.1 Meter Communications: Issuing Messages and Commands 7.21.1 Customer Supply Monitoring File Name: NSMP_SMI_VendorsRFI_V1.0.doc Page 4 of 37

It is assumed the majority of the differences between the SMI F.S. and Victorian AMI will require enhanced meter software. These enhancements have the potential to affect the spare processor capacity allocated for future software releases (under Requirement 7.14 Software Upgrades). Question Vendor Response Please estimate the reduction in head room (spare capacity) that has been included in your estimates, preferably indicating the current percentage utilisation and future utilisation of all processor resources in the meter. The NSMP would like to avoid differences between solutions deployed in jurisdictional areas. A desirable solution would provide reconfigurable settings allowing one meter to satisfy both the SMI F.S. and Victorian AMI Requirements. Question Vendor Response Is it possible for the same meter hardware to be used for both the SMI F.S. and Victorian AMI? If it is not possible to provide a solution meeting both requirements please describe which requirements prevent this from being possible. Version 0.26 of the SMI F.S. does not currently specify requirements for Interoperability for meters/devices at the Application Layer (7.18.1) or Hardware Component Interoperability (7.19.1). Interoperability at the application layer would allow a Smart Meter Management System (SMMS) to configure and control a range of different vendors smart meters. For this to work it would require the use of a common communications metering protocol. Interoperability at the hardware layer allows a single meter to be fitted with a range of communications options. Question Vendor Response Please discuss how your solution provides interoperability at the application layer. Please discuss how your solution provides interoperability at the hardware layer The NSMP is aware that some of the functionality that is being requested is unique to the Australian market. It invites vendors to suggest how aligning the SMI F.S. with other markets would provide access to a wider range of solutions. Table 3 invites vendors to suggest functionality that could be modified to enable the SMI F.S. to align with overseas markets. Please outline anticipated cost reduction by making these changes.

3.3 Smart Meter Management System Requirements Section 5 of the SMI F.S. details the Smart Metering Infrastructure components. The Smart Meter Management System (SMMS) is intimately involved in the delivery of the Infrastructure levels. This section aims to determine the vendor s ability to support the SMI requirements remotely. (Note that Levels are to be explored in Section 1.1 of this document). The column invites vendors to provide clarification where the stated requirements may lead to uncertainty or ambiguity in the specification. The column provides an opportunity for vendors to outline cost implications to meet the SMI F.S. compared to the Victorian AMI specification. Vendors are also invited to suggest changes to the requirements which would provide similar functionality but at a lower cost.

Please discuss how the offered SMMS satisfies the requirements for interoperability? Section 7.20.1 requires the SMMS to provide Message prioritisation Please briefly explain the level of control provide in your solution File Name: NSMP_SMI_VendorsRFI_V1.0.doc Page 8 of 37

3.4 Smart Meter Infrastructure Level (including communications) Version 0.26 of the SMI functionality specification does not differentiate in different deployment scenarios. In the preparation of the NERA Cost Benefit Analysis the assumption was that different technologies would be deployed in different jurisdictions. The NERA analysis assumed: Urban: Mesh radio (97%) with GPRS (3% fill-in) Rural: PLC Remote: PLC In order to provide indicative percentages in each area, NERA also defined the distinction between urban and rural as notionally at a density of less than 100 customers per square kilometre. Their assumed allocation of customers nationally is: 86 per cent urban ; 10 per cent rural and 4 per cent remote. The NSSC would like to explore the feasibility of either setting a single performance level for all areas or for setting different for urban, rural and remote areas.. For the purposes of comparison the following theoretical deployment areas are provided: Urban Rural on grid Meter population of at least 200,000 meters with a density of up to 500 meters per square kilometre. Consider that the majority of meters are located inside metal meter boxes located at a height of 1.5m mounted on the side of domestic premise or in high rise buildings. The deployment can assume reliable 3G cellular telecommunications coverage and approximately 100 homes per distribution transformer. The terrain should be considered to be gently undulating with light coverage of trees. There is a mix of overhead and underground supply. Meter population of at least 5,000 with 80% located in town centre and the remainder spread around the town with a density 5-50 meters per square kilometre. In the town centre consider that the majority of meters are located inside metal meter boxes located at height of 1.5m on the side of domestic premise. In the town centre can assume reliable 3G cellular coverage, however out of town telecommunications coverage nominally requires higher performance handsets 2. In the township assume 100 homes per distribution transformer however this decreases to 10 homes outside the town centre. All electricity distribution is overhead. Remote on grid Meter population of 1,000 with meter density between 0.25 to 5 meters per square kilometre with no major meter concentrations. The terrain is flat with minimal tree coverage. All electricity distribution is overhead, includinga number of SWER lines. 3G cellular coverage is only available at distribution zone substations. Sample selection for Group Messaging For Group messaging the stated performance level should be achievable when the entire meter population in a distribution area is involved (note that the SMI F.S. has not assumed that the offered solution supports message broadcast. In the high level architectural summary please indicate if your solution is using message broadcast to achieve the performance level). Clarification of the assumed sample selection for Individual Levels In the response to the Levels vendors are requested to ensure that they are presenting results for a random selection of meters across the total meter population. Vendors should not assume a best case scenario. For clarification: this occurs for Levels relating to commands to individual meters which state x% of the number of. Where the vendor feels that the selection may influence the reported the response should clearly state the assumptions that have been made to meet the stated performance level. High level architecture Vendors are requested to provide a high level architecture describing their proposed solution. Please provide a separate high level architecture for each deployment area highlighting any assumptions made. For each deployment area please summarise the major differences in the high level architecture. If your solution is not viable in a deployment area then please suggest changes that would be required to enable you to offer your solution. The following Tables ask vendors to separately respond to three different in each of the assumed deployment areas. The Smart Metering Program would like to determine the feasibility and cost implications to meet the three in each of the deployment areas. The performance level attempts to provide all the information necessary to allow the Smart Meter Communications Network (SMCN) to be appropriately scaled. The Column invites vendors to Provide clarification where the stated performance level requirements may lead to uncertainty or ambiguity Suggest additional information that should be added to assist in the design of the SMCN? The tables present three, a lower performance level ( ), the performance level specified in the Victorian AMI specification ( Level B) and a higher performance level ( ). The Column invites vendors to: Compare the costs of meeting the three different Suggest changes to the proposed enabling a simpler implementation If the suggested Level is infeasible then this should be highlighted in the response Note: The stated are measured from the Smart Meter Management System to the meter and will therefore include the smart meter management system, smart meter communications network and the smart meter communications modem. As such the response provided in Column #2 provides the cost implications to meet each of the three including costs in the Smart Meter Management System, the Smart Meter Communications Network and the modems included in the Smart Meter. 2 For example handsets certified by Telstra with the Blue Tick File Name: NSMP_SMI_VendorsRFI_V1.0.doc Page 9 of 37
