FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61968-9 has been prepared by IEC technical committee 57: Power

INTRODUCTION
The purpose of this document is to define a standard for the integration of metering systems
(MS), which would include traditional (one or two-way) automated meter reading (AMR)
systems, with other systems and business functions within the scope of IEC 61968. The
scope of this standard is the exchange of information between a metering system and other
systems within the utility enterprise. The specific details of communication protocols those
systems employ are outside the scope of this standard. Instead, this standard will recognize
and model the general capabilities that can be potentially provided by advanced and/or legacy
meter infrastructures, including two-way communication capabilities such as load control,
dynamic pricing, outage detection, distributed energy resource (DER) control signals and on-
request read. In this way, this standard will not be impacted by the specification, development
and/or deployment of next generation meter infrastructures, either through the use of
standards or proprietary means.
The IEC 61968 series of standards is intended to facilitate inter-application integration as
opposed to intra-application integration. Intra-application integration is aimed at programs in
the same application system, usually communicating with each other using middleware that is
embedded in their underlying runtime environment, and tends to be optimized for close, real-
time, synchronous connections and interactive request/reply or conversation communication
models. Therefore, these interface standards are relevant to loosely coupled applications with
more heterogeneity in languages, operating systems, protocols and management tools. This
series of standards is intended to support applications that need to exchange data every few
seconds, minutes, or hours rather than waiting for a nightly batch run. This series of
standards, which are intended to be implemented with middleware services that exchange
messages among applications, will complement, not replace utility data warehouses,
database gateways, and operational stores.
As used in IEC 61968, a distribution management system (DMS) consists of various
distributed application components for the utility to manage electrical distribution networks.
These capabilities include monitoring and control of equipment for power delivery,
management processes to ensure system reliability, voltage management, demand-side
management, outage management, work management, automated mapping and facilities
management. Standard interfaces are defined for each class of applications identified in the
interface reference model (IRM), which is described in IEC 61968-1: System interfaces for
distribution management – Part 1: Interface architecture and general requirements.

APPLICATION INTEGRATION AT ELECTRIC UTILITIES –
SYSTEM INTERFACES FOR DISTRIBUTION MANAGEMENT –

Part 9: Interfaces for meter reading and control

1 Scope
This document is Part 9 of the IEC 61968 standard and specifies the information content of a
set of message types that can be used to support many of the business functions related to
meter reading and control. Typical uses of the message types include meter reading, meter
control, meter events, customer data synchronization and customer switching. Although
intended primarily for electrical distribution networks, IEC 61968-9 can be used for other
metering applications, including non-electrical metered quantities necessary to support gas
and water networks.
The purpose of this document is to define a standard for the integration of metering systems
(MS), which includes traditional manual systems, and (one or two-way) automated meter
reading (AMR) systems, with other systems and business functions within the scope of
IEC 61968. The scope of this International Standard is the exchange of information between a
metering system and other systems within the utility enterprise. The specific details of
communication protocols those systems employ are outside the scope of this standard.
Instead, this standard will recognize and model the general capabilities that can be potentially
provided by advanced and/or legacy meter infrastructures, including two-way communication
capabilities such as load control, dynamic pricing, outage detection, distributed energy
resource (DER) control signals and on-request read. In this way, this standard will not be
impacted by the specification, development and/or deployment of next generation meter
infrastructures either through the use of standards or proprietary means.
The capabilities and information provided by a meter reading system are important for a
variety of purposes, including (but not limited to) interval data, time-based demand data, time-
based energy data (usage and production), outage management, service interruption, service
restoration, quality of service monitoring, distribution network analysis, distribution planning,
demand reduction, customer billing and work management. This standard also extends the
CIM (Common Information Model) to support the exchange of meter data.
