Dimension Economy
Sub-Dimension ICT
Category Electricity Supply
KPI Name Electricity Supply ICT Monitoring
KPI No. EC: ICT: ES: 2A Type: Advanced Type: Smart

Definition / Percentage of electricity supply system monitored by ICT
Description

Rationale / The city should report on the extent that a SCADA (supervisory control and data
Interpretation / acquisition) system (or similar system) has been implemented to cover the
Benchmarking electricity supply system.
Modern SCADA systems replace the manual labour to perform electrical
distribution tasks and manual processes in distribution systems with automated
equipment. SCADA maximizes the efficiency of power distribution systems by
providing features such as real-time views into the operations, data trending and
logging, maintenance of desired voltages, currents and power factors, alarms
generation, etc.
SCADA performs automatic monitoring, protecting and controlling of various
equipment in distribution systems with the use of Intelligent Electronic Devices (or
RTUs). It restores the power service during fault conditions and also maintains the
desired operating conditions.
SCADA improves the reliability of supply by reducing duration of outages while
providing cost-effective operations of the distribution system. Therefore, SCADA
supervises the entire electrical distribution system. The major functions of SCADA
can be categorized into the following types:
▪ Substation Control;
▪ Feeder Control; and
▪ End User Load Control
ICT control has shown to be effective in improving the efficiency of an electricity
supply system.
An increasing trend and higher values are considered positive.
