CHAPTER 14 - Iskandar Malaysia

SECTION B
PLANNING AND IMPLEMENTATION
14.3 Power Supply
The provision of sufficient and uninterrupted electric power is essential to
support urban growth. With this in mind, the generation and distribution
of power needs to be properly planned, making use of the latest
technology as required.
B. Current Main Substation and Capacity
The present supply of electric power in the study area is sufficient. Based
on Table 14.2, the capacity of 23 main intake substations could meet
the demand of SJER and produce 2040 MVA with a maximum capacity
of 994MV. Figure 14.1 shows the location of the intake substations in the
study areas.

KEY DIRECTION
Ensure sufficient supply of power to cater for the growth of
SJER and to support its objective of becoming a world class
sustainable conurbation.
To ensure that the reliability of power within SJER meets the
standards set for MSC Cybercities and Cybercentres.

A. Enhance the Reliability of Power Supply
The following proposed targets will be set for SJER i.e.:
■ Improve System Average Interruption Duration Index (SAIDI) from
the current 105 minutes/customer/year (2004) 1 to less than 20
minutes/customer/year; and
■ System Average Interruption Frequency Indexes (SAIFI) from 1.11
(2004) to less than 0.5
