IEC 63152:2020 pdf download.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.

4 Concept of city service continuity (CSC) against disasters
Organizations that receive grid electricity supply need to secure back-up power sources in order to be able to continue providing their services when the grid electricity supply is discontinued due to disasters, up until the time when the electricity supply is back to normal. Activities in a city are supported by the continuous supply of various services (water and sewage, gas, transport, hospitals, communications, logistics, etc.), and such services are supplied through facilities and devices, most of which, in general, need electricity from the grid to operate. Therefore, the loss of the grid electricity supply due to disasters results in the potential impact of a massive loss of such services. For the city services to recover quickly so that the major loss of services can be minimized when a disaster strikes, organizations should prepare in advance to ensure that they can secure a minimum level of services until electricity supply returns to normal, making arrangements to facilitate full recovery of services at the earliest possible stage as shown in Figure 1. Each organization shall establish a business continuity plan (BCP) in order to address this need.
