IEC 63152 pdf – Smart cities – City service continuity against disasters – The role of the electrical supply
This document establishes concepts and gives guidelines to help sustain a variety of cityservices on the occasion of a disaster from the perspective of providing electricity. t outlines
the basic concepts on how multiple city services can cooperate and continue by electricitycontinuity plan(s) and electricity continuity system(s). lt also specifies methods and means toestablish these.

4Concept of city service continuity (csc) against disasters
Organizations that receive grid electricity supply need to secure back-up power sources inorder to be able to continue providing their services when the grid electricity supply isdiscontinued 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 andsewage，gas,transport,hospitals，communications，logistics,etc.),and such services aresupplied through facilities and devices,most of which,in general, need electricity from thegrid 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 minimizedwhen a disaster strikes,organizations should prepare in advance to ensure that they cansecure a minimum level of services until electricity supply returns to normal，makingarrangements to facilitate full recovery of services at the earliest possible stage as shown inFigure 1. Each organization shall establish a business continuity plan (BCP) in order toaddress this need.
