Discussion

I want to discuss about the presentation delivered by Ir Hjh Fazilah Mat Yatim. I chose to write about this topic because the content of the presentation struck a certain chord with my feelings and attitudes towards GIS and its contribution and achievement in TNB Distribution.  

GIS in TNB Distribution

  • Shape Regulatory Outcome – To support GSL 1 (frequency of interruption) & GSL 2 (restoration time)
  • Exceed Customer Expectation – Providing accurate customer location data
  • Drive Operational Cost Efficiency – Strategize planning of new supply, operation & maintenance
  • Transform Organization – Managing assets geographically

An Overview of GIS Distribution Network

GIS Usage: - a tool for data captured, stored, edit, analyzed, integrate, manage, query and display in geographic forms

Infrastructure: - Enterprise Wide System

                           - GIS software is GE Smallworld 4.1.2

                           - WGS 84 for GPS coordinate system

                           - UTM 47N for projection

Applications: GIS Functions

  • Asset Register
  • Supply New Connection
  • Reconnection
  • Project Planning & Wayleave Planning
  • Construction Projects
  • Customer Service Support

Applications: GIS Solutions

DESKTOP – Use to digitize lot of TNB network assets and perform specific electric network analysis or tracing

MOBILE – A tool to allow doing site visit verification and maintenance work on site

LITE EDITOR – Use web browser for simple search, simple redline and sketching

SMARTVIEW – Use to visualize and locate TNB assets on Google Map with street view and directions

MYSIGHT – Use to add and locate selected TNB assets on Google Map on mobile phone

Why TNB embark on GIS?

  • Technology disruptions: IR 4.0

Dramatically changing the power sector and customer demands

  • Regulations evolving: MESI 2.0 reforms

Increasing competition due to market liberalization

  • Shareholder expectations

Shareholders demanding greater returns and transparency

  • Economic shifts

Power is shifting towards Asian and emerging market economies

GIS current achievement in TNB Distribution
