SCADA Monitoring System Eliminates Manual Meter Checking for a Leading Energy and Manufacturing Client, Achieving Real-Time Visibility Across 1,500 Meters on a Single Platform

Our client is a large-scale organization operating across the energy and manufacturing sectors. With an extensive network of 1,500 energy meters spread across their facilities, they are responsible for monitoring and analyzing a vast array of electrical parameters to ensure operational efficiency, energy optimization, and infrastructure reliability. To protect their confidentiality, the client name has not been disclosed in this case study.

The client had no centralized system to monitor their 1,500 Modbus energy meters. Accessing data required a worker to physically walk to each meter, read the values, note them manually, and perform separate data entry. With 1,500 meters and 20 to 25 parameters each, workers were completing this full round every hour — consuming enormous time and manpower while remaining highly vulnerable to human error and missed readings.

We proposed a purpose-built SCADA monitoring platform designed around the industrial realities of the client’s infrastructure. The solution required both a hardware and software component: Modbus RTU to TCP/IP gateway converters would be installed at each meter to bridge the gap between the legacy Modbus protocol and a modern networked system, while a robust backend service would handle continuous, high-frequency data polling at scale. The platform would then surface all of this data through a feature-rich web interface built for operational teams.

Our engagement began with a full site and infrastructure assessment to understand the physical layout of all 1,500 meters. Once the hardware layer was in place, our backend team built a high-performance data polling service in Node.js capable of continuously querying all meters via Modbus, pulling 20 to 25 electrical parameters per meter every 30 seconds, and persisting that data into a time-series optimized database stack built on PostgreSQL, TimescaleDB, and FlexDB. Our frontend team developed a clean, React-based dashboard giving the client’s team complete real-time visibility from a single screen. The custom screen builder lets users organize meters into logical groups without any technical knowledge. The configurable alarm system notifies personnel via email and SMS when any threshold is exceeded, while the automated alert system detects and flags any meter going offline within seconds — down from up to an hour.
