It focuses only on an assessment of the risk of landslides concerning the proposed route of transmission. This study presents the potential of an integrated system using the Geographical Information System (GIS) and Remote Sensing techniques in substation selection to develop an automatic and intelligence method for substation planning in this specific delicate area of the environment. During the selection of the proposed substation, a social impact assessment was also included in this research by defining requirements, problems as well as suitable mitigation measures. With this research, all spatial data for South Putrajaya is acquired and the previous system can be fully utilized. Spatial data from this research were also used to define soil type and flood-prone areas. Finally, this system will be used to assist TNBs in gazetting by applying sustainable concepts in their Transmission Route and Corridor by following Section 21 and Section 22 ACT 172 1973.

INTRODUCTION The substation is a component of the power generation, transmission, and distribution system [1]. It serves as electricity supply sources for the local distribution fields where they are situated. The primary roles of the substation are to receive energy transmitted at high voltage from the generating station and to reduce the voltage to a standard that is suitable for local distribution and to provide switching facilities [2]. At some places, the existing substation facilities are not sufficient to supply energy in a service region due to the rapid economic and population growth. In such cases, new substations must be built or replaced in some critical instances to supply new demand [3]. The decision on the optimum place and the number of new substations to be built is difficult in many cases [4], [5]. Determination of the location of new substations generally depends on several conditions including geographical constraints of the region that horizontal load growth occurs Revised Manuscript Received on September 22, 2019.

The Geographical Information System (GIS) has significantly improved the energy industry efficiency [7],[8]. GIS is widely used for fault analysis, optimization of networks, load forecasting, cost estimation and selection of suitable areas, etc [9]. GIS applications serve a significant part in designing, analyzing and controlling contemporary energy systems. It improves the visualization of the energy system by associating spatial data with electrical network transmission and other assets [9]. A. Study Area South Putrajaya was chosen as the study area in this study. According to the land use agriculture map, Putrajaya South majorly consists of the federal government administration building, village, and orchard. The topography of the area land consists of slightly-to- moderately hilly terrain with elevation varies from 20 meters to 240 meters. Locations of the study area are shown in Fig. 1.
