Patna: Patna’s electricity network is set for a major upgrade with city power substations being integrated into a Supervisory Control and Data Acquisition (SCADA) system, enabling real-time monitoring, quicker fault localization, and remote switching to reduce outage frequency and duration. The utility will connect key 33/11kV substations and associated feeders to a central SCADA control room, where operators can view live load, voltage, and breaker status, isolate faulty sections, reroute supply, and restore power without waiting for field teams to physically reach each site.
How SCADA will work
• Sensors and Remote Terminal Units (RTUs) at substations/feeders will stream live data—current, voltage, breaker/trip alarms—to the control center.
• The Energy Management System will flag overloads, low voltage pockets, or trips and suggest sectionalizing to keep healthy areas powered.
• Operators can remotely open/close breakers, change load flow paths, and dispatch crews with precise fault locations, cutting restoration time.
• Historical data will support preventive maintenance, load balancing, and targeted upgrades in high-loss or high-fault zones.
What consumers can expect
• Faster outage detection and restoration through automated alarms and remote switching.
• Fewer “area-wide” blackouts as faulty stretches are isolated and supply is back-fed to unaffected neighborhoods.
• Improved voltage profile and planned maintenance windows communicated in advance via control-room scheduling.
The rollout aims to modernize urban distribution in phases, covering high-density pockets first, integrating ring-fed feeders for redundancy, and linking field crews via mobile work management so repairs and switching orders are synchronized. Officials said SCADA will also help curb technical losses, deter theft through anomaly detection, and provide reliable data for capacity augmentation ahead of peak seasons.
