2. Objectives and scope

The objective of this technical specification is the identification and specification of functional, technical, economical and general requirements of an Advanced Metering Infrastructure (AMI), taking into account the needs of the various stakeholders (consumers, network retailers, etc.) This Specification is divided into three areas of study: overall requirements, field components requirements and communication requirements. The first area, overall requirements, covers the general the economical requirements that should be requested to an AMI. The general requirements include aspects such as security, interoperability, robustness, scalability, maintenance, performance and management. The requirsystems functions are analyzed through use cases describing the endprocesses of the utility. The economical requirements will help optimize capital expenditure (CAPEX) and operational expenditure (price of field components, minimizing the cost of installation, minimizing the cost of system integration, minimizing the cost of operation and through loss protection and reduction. The second area of study of this deliverable is the field components requirements that should cover all the envisaged architectural elements of an AMI, including meters and concentrators. Both functional and technical requirements will be analyzed for field components. The last area of this deliverable describes the requirements for thecommunications to be established between smart meters and the dataconcentrator, but also between meters and data concentrator and other and between meters and data concentrators and the central system.Requirements are divided into three complementa

- Minimum requirements are absolutely necessary to reach the aimed benefits.

- Advanced requirements are of high value but might not be strictly required at all deployments.

- Optional requirements include addadded services toward smart grids or country specific requirements.

3.1.2 Security

Cyber-security is a well-known issue in classical IT systems. For some years, there has been a growing interest in cybersystems, which are more complex, independent and interconnected. Authorities put a special emphasize on Critical InfrastrucIndustrial Automation Control Systems, especially infrastructure supporting energy, transport, and telecommunications. Metering is directly concerned by this focus. Security is everywhere in metering process, from the meter and the datconcentrator to the back-office information system, including each network and media used to communicate (home network, public network and enterprise network). Also all components are concerned and we need to handle a global security. All partners, from manufacturers to suppliers and regulation authorities have to work together for awarenesssystems.

An efficient design important in order to fulfil the future enlargement demands. If the design fails when thequantity increases then the system is not able to scale.AMI system scalability can be measured in various dimensions, such as:

- Load scalability: The ability for an AMI system to easily expand and contract to accommodate heavier or lighter traffic. Alternatively, the ease with which a system or component can be modified, added, or removed, to accommodate changing load.

- Geographic scalability: The abiliusability regardless of expansion from concentration in a local area to a more distributed geographic pattern.

- Administrative scalability: The ability for an increasing number of organizations to easily share a single distributed system.

These actions include the combination of all technical and corresponding administrative, managerial, and supervision actions. The maintenance can be corrective, preventive or be part of a process of continuous improvement. In an AMI system, the requirements for maintenance are focused on enabling remote maintenance. The equipment shall facilitate remote maintenance through functionality for:

- Automatic error detection (hardware, software, - gathering diagnostics - configuration of the metering installation (as a whole and individual components)- gathering the state of the metering installation (parameters)

In the same way, the operational system has to provide a set of useful features in order to assure its maintenance:

- automatic diagnosis and monitoring means- ease in terms of system migration and evolution- user friendly exploitation interfaces- Minimization of additional operations

Starting from the stage of conceptionorganization itself. As mentioned, the organization’s administrative and managerial supervision plays a key role in the whole system maintenance.Indicators can be defined to characterize corrective maintenance, such

- MDT (Mean Down Time): average time the system in unavailable (for anyreason)

- MTTR (Mean Time To Repair): average repair time for a component - MWT (Mean Wait Time): all time during downtime that is not repair

time(MDT=MWT+MTTR) For an AMI system, these indicators may be set to values in accordance with the SLA (Service Level Agreements) corresponding to the functional services offered on the AMI.


All the possible steps to reduce maintenance (corrective, preventive or ongoing actions) of the AMI system must be taken. In particular, automatic and remote maintenance actions will be preferred over manual actions.

1) Meter reading electricity (E) A meter reading for electricity contains any demanded register value, or a presubset of register values, of the meter. Meter reading is used for billing, onreads and for knowing the status of the meter. As electricity meters support multi-tariffs for both energy directions, each electricity meter reading can also contain an indication of the tariff associated with each register value. Each value should be specified according to related class that was mentioned in IEC 62056-62 and its appendix.
