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.

INTRODUCTION
0.1 General
It is important that organizations providing services are able to develop and implement
preparedness measures to maintain and restore required services in the event of a disaster.
Because many of the services depend on electricity, an electricity continuity plan (ECP) and an
electricity continuity system (ECS) can help maintain and restore necessary services in power
failure that is caused by a disaster. IEC 63152 describes the concept and minimum
requirements of ECP and ECS based on a business continuity plan (BCP).
However, depending on the type, degree, and quality of services, there are various ways to
respond to disasters, and ECP and ECS cannot be created in the same way.
This document is designed to serve as a guideline for the design of basic parts by showing the
process and points to be noted in the preparation of ECP and ECS for power outages based on
normal service.
It is assumed that ECP and ECS will be useful to urban developers, urban operators, public
service providers, disaster managers and system integrators, and manufacturers of systems
related equipment and facilities.
0.2 Why ECP and ECS are needed
Services in cities are not just public services. There are a lot of different types of services and
service users such as residential services, transportation services, medical services,
manufacturing services, etc. These services are also composed of various services.
Electricity is a very important resource to provide these services. Physical damage can be
unavoidable due to a disaster, but even in areas not directly affected physically, the power
disruption affects the surrounding areas, making it impossible to maintain normal services.
For example, what about the transportation system when there is a blackout due to a disaster?
Figure 1 – Impact of power outage in traffic
During normal times, traffic signals display instructions regularly, and the traffic centre can
control traffic signals based on traffic volume sensor information.
---------------------- Page: 9 ----------------------
– 8 – IEC SRD 63152-2:2022 IEC 2022
As shown in Figure 1, a power failure causes traffic jams in many places because traffic lights
cannot display instructions. In that case, the traffic centre will not be able to grasp the traffic
jam situation and will not be able to give appropriate instructions to emergency vehicles. Of
course, the distribution will be delayed due to the traffic jam. Also, if the signal display
disappears, there can be many accidents. (See Annex A for more examples.)
It would be helpful to have a system (ECS) in place to back up the power supply to important
traffic signals, traffic sensors, etc., and to plan (ECP) activities to minimize the adverse effects
on traffic with the minimum necessary information in the event of a power failure.
In addition, ECP and ECS cannot be used effectively if users are not familiar with them. It is
important to conduct regular training to familiarize users with ECP and ECS. Furthermore, small
power outages can be opportunities to check the effectiveness of ECP and ECS as well as
identify points for improvements.
0.3 How to develop ECP and ECS using this document
With this in mind, this document shows as much as possible what should be considered when
continuing service in the event of a power failure.
Here is how to develop the core ECP and ECS (See Figure 2).
Figure 2 – Design flow image of ECP and ECS
First of all, a conceptual design is performed while clarifying the following points:
• assumption of disaster and level of damage to the city and to the organization;
• all services provided in the organization in normal time;
• policy and intention regarding what service and what level of service needs to be secured
at the time of disaster.
Next, use cases for establishing ECP and ECS are described using templates to match the
conceptual design, and basic requirements are summarized in the description as a basic design.
Finally, in the detailed design, the basic design is described in detail in the management
timetable to clarify the overall picture of the disaster response, and then the ECP document is
prepared and the ECS is designed.
0.4 What is the benefit?
There are many benefits to ECP and ECS, in addition to maintaining a certain level of service
after a disaster. They include the following.
---------------------- Page: 10 ----------------------
IEC SRD 63152-2:2022 IEC 2022 – 9 –
• Increase of the likelihood of early recovery.
The implementation of ECP and ECS not only ensures that basic services are maintained
for a period of time after a disaster, but also increases the likelihood of early recovery.
If ECP and ECS maintain basic services during a power outage, they reduce the burden of
responding to services that need to be restored after a power outage. In addition, they will
reserve the capacity to create scenarios and preparation for the recovery during the power
outage.
• ECP and ECS collaboration across multiple services.
By considering ECP and ECS for each of the important services, and by understanding and
coordinating the measures related among them, we can expand what can be covered by
multiple ECP and ECS.
As a result, we will be able to cover more facilities, more areas, and even apply them to the
supply chain.
If these efforts are accumulated, it will become possible to build cities that can respond to
a variety of power outages, not just in times of disaster.
• Preparation and application for multiple disasters response (e.g. coronavirus + earthquake).
Sometimes multiple disasters occur at the same time. For example, an earthquake can occur
where an infectious disease, such as a coronavirus, is widespread.
ECP controls human activity and ECS controls systems. When disasters are compounded
in this way, staff shortages also need to be addressed. Several additional measures can be
needed to identify gaps in staff and maintain ECP and ECS.
The effectiveness of ECP and ECS can be enhanced by considering them in various disaster
situations.
It is expected that the use of this document will enable many service providers to aim for more
effective and advanced disaster response.
