CITY SERVICE CONTINUITY AGAINST DISASTERS –
THE ROLE OF THE ELECTRICAL SUPPLY

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.

INTRODUCTION
Cities are facing many kinds of potential threats which affect the continuity of city services.
There exists, therefore, a great need to establish safe and secure societies in which negative
impacts on city services to the citizens are minimized and city services are continuously
available to them during a period of emergency. There is no doubt that, in modern cities,
electricity plays a critical role in maintaining city services.
This document provides requirements and guidelines to ensure that city services can be
sustained when the power supply from the grids is discontinued because of disasters.
The users of this document are assumed to be city developers, city operators, equipment
manufacturers, essential service providers and disaster management personnel.

SMART CITIES –
CITY SERVICE CONTINUITY AGAINST DISASTERS –
THE ROLE OF THE ELECTRICAL SUPPLY

1 Scope
This document establishes concepts and gives guidelines to help sustain a variety of city
services on the occasion of a disaster from the perspective of providing electricity. It outlines
the basic concepts on how multiple city services can cooperate and continue by electricity
continuity plan(s) and electricity continuity system(s). It also specifies methods and means to
establish these.
2 Normative references
