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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

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.

The main task of IEC technical committees is to prepare International Standards. In

exceptional circumstances, a technical committee may propose the publication of a technical

specification when

• the required support cannot be obtained for the publication of an International Standard,

despite repeated efforts, or

• the subject is still under technical development or where, for any other reason, there is the

future but no immediate possibility of an agreement on an International Standard.

Technical specifications are subject to review within three years of publication to decide

whether they can be transformed into International Standards.

IEC TS 62872-1, which is a technical specification, has been prepared by IEC technical

committee 65: Industrial-process measurement, control and automation.

This first edition edition cancels and replaces IEC TS 62872, published in 2015. This edition

constitutes a technical revision.
---------------------- Page: 7 ----------------------

INTRODUCTION

The World Energy Outlook 2017 [19] reported that industry consumed over 40 % of world

electricity generation in 2015. Furthermore, industry itself is a significant generator of internal

power, with many facilities increasingly implementing their own generation, co-generation and

energy storage resources. As a major energy consumer, the ability of some industries to

schedule their consumption can be used to minimize peak demands on the electrical grid. As

an energy supplier, industries with in-house generation or storage resources can also assist

in grid load management. While some larger industrial facilities already manage their use and

supply of electric power, more widespread deployment, especially by smaller facilities, will

depend upon the availability of a readily available standard interface between industrial

automation equipment and the “smart grid”.

NOTE In this document “smart grid” is used to refer to the external-to-industry entity with which industry interacts

for the purpose of energy management. In other documents this term can be used to refer to all of the elements,

including internal industrial energy elements, which work together to optimize energy generation and use.

Industry is a major consumer of electric power and in many cases this consumption can be

scheduled to assist in minimizing overall peak demands on the smart grid. In addition, many

industrial facilities have in-house generation or storage resources. These facilities can assist

in smart grid load and supply management. For example, in-house generation can supply

energy to the smart grid and to the facility. Furthermore, storage resources can assist in smart

grid load management. While some larger industrial facilities already manage their use and

supply of electric power, more widespread deployment, especially by smaller facilities, will

depend upon the availability of readily available standard automated interfaces.

Standards are already being developed for home and building automation interfaces to the

smart grid; however, the requirements of industry differ significantly and are addressed in this

document. For industry, the planning of energy resources and production processes are under

the responsibility of the facility energy planner and production planner and the operations are

under the responsibility of the facility energy operator and production operator.

Incorrect operation of a resource could impact the safety of personnel, the facility, the

environment or lead to production failure and equipment damage. In addition, larger facilities

may have in-house production planning capabilities which might be co-ordinated with smart

grid planning, to allow longer term energy planning.
