GridWatch: The Future of Smart Substation Monitoring Has Arrived

As electrical networks evolve to meet rising demand, decentralised generation, electrification and sustainability targets, utilities face increasing pressure to modernise ageing infrastructure while maintaining reliability and operational efficiency.

The challenge?

Many MV/LV transformer substations still operate with limited visibility, reactive maintenance strategies and little real-time operational intelligence.

That is where GridWatch changes the game.

GridWatch is an intelligent monitoring solution designed specifically for MV/LV transformer substations and low-voltage distribution networks. Combining real-time electrical measurements, environmental sensing and remote communications, GridWatch gives utilities unprecedented insight into the health and performance of their infrastructure.

Why Utilities Need Smarter Substation Monitoring

Across the energy sector, operators are facing common challenges:

  • Increasing transformer loading due to electrification
  • Difficulty identifying overloads and network imbalance
  • Rising maintenance costs
  • Limited visibility into LV feeder performance
  • Unplanned outages caused by overheating or ageing assets
  • Pressure to optimise network capacity for new connections

Traditional maintenance models rely heavily on scheduled inspections and manual diagnostics. In today’s grid environment, reactive maintenance is no longer enough.

Utilities need real-time operational intelligence.

GridWatch delivers exactly that.

 

What Is GridWatch?

GridWatch is a comprehensive monitoring platform for MV/LV substations that combines:

  • Electrical metering
  • Transformer monitoring
  • Environmental sensing
  • Alarm management
  • Remote communications
  • Data analytics and dashboards

The solution continuously monitors critical substation parameters including:

  • Transformer load and power factor
  • Current and voltage measurements
  • Transformer imbalance
  • Hot spot temperatures
  • Ambient temperature and humidity
  • Flood detection
  • Door opening and movement detection
  • Ventilation control
  • LV feeder performance

The result is a smarter, safer and more resilient electrical network.

Real-Time Visibility Across the Network

One of GridWatch’s greatest strengths is its ability to provide operators with live visibility into transformer stations and LV feeders.

Using the integrated GridWatch Dashboard, operators can:

  • Monitor real-time measurements
  • Track transformer KPIs
  • Analyse load trends over time
  • Detect abnormal operating conditions
  • Configure intelligent alarms
  • Identify overloaded feeders
  • Compare phase loads and imbalances

The platform supports long-term trend analysis with 10-minute, hourly, daily, weekly and monthly averages, enabling better operational and investment decisions.

Prevent Failures Before They Happen

Transformer overheating and connection hot spots are among the leading causes of substation failures.

GridWatch continuously monitors:

  • Transformer surface temperatures
  • HV/LV connection hot spots
  • Environmental conditions within substations

By detecting thermal anomalies early, utilities can intervene before failures occur, significantly reducing downtime, repair costs and asset degradation.

This predictive approach helps extend transformer lifespan while improving overall network reliability.

 

Designed for...

GridWatch deployment

A major barrier to digital transformation is installation complexity.

GridWatch has been specifically engineered for fast and simple deployment, featuring:

  • Split-core current sensors
  • Rogowski coils
  • Pre-wired environmental sensors
  • Pre-configured wireless sensors
  • Compact cabinet designs

Installation downtime is minimised, allowing utilities to modernise substations quickly and efficiently.

 

Scalable for Every Network

No two substations are identical and GridWatch recognises that.

The system is available in multiple configurations, including:

GridWatch C50

A compact monitoring and control solution ideal for streamlined deployments and standard monitoring applications.

GridWatch C200

An advanced measurement, control and communication platform with expanded functionality including:

  • Remote logging
  • MQTT alarm publishing
  • OPC UA support
  • Advanced gateway functions
  • Additional environmental monitoring
  • Battery backup options

This flexibility allows utilities to scale deployments based on operational needs and budget.

 

Open, Connected and Future-Ready

Modern utilities require interoperability.

GridWatch supports a wide range of industry-standard communication protocols including:

  • Modbus TCP/RTU
  • MQTT
  • FTP Push
  • SMTP
  • OPC UA
  • HTTPS Web Services

The system integrates easily with:

  • SCADA platforms
  • Supervisory systems
  • Utility dashboards
  • Cloud-based analytics platforms

This open architecture ensures GridWatch can fit seamlessly into both existing and future digital grid strategies.

 

Smarter Data. Better Decisions.

Data is only valuable when it drives action.

GridWatch transforms raw measurements into actionable intelligence by helping utilities:

  • Optimise maintenance schedules
  • Reduce technical and non-technical losses
  • Prevent transformer overloading
  • Improve load balancing
  • Maximise available network capacity
  • Support new customer connections
  • Reduce operational costs

In one documented example, analysis from the GridWatch Dashboard validated the replacement of a heavily loaded 400 kVA transformer with a 630 kVA unit, reducing load rate from 75% to 45%.

 

Supporting the Transition to Smarter Grids

As utilities continue investing in decarbonisation, EV infrastructure and distributed energy resources, LV network visibility becomes increasingly critical.

GridWatch provides the digital foundation needed to:

  • Support low-carbon electrification
  • Improve grid resilience
  • Enable predictive maintenance
  • Increase operational efficiency
  • Enhance network sustainability

In short, GridWatch helps utilities move from reactive operations to intelligent network management.

 

The Takeaway

The future of energy distribution depends on smarter infrastructure, better visibility and data-driven decision making.

GridWatch delivers all three.

By combining advanced monitoring, rapid deployment, scalable architecture and powerful analytics, GridWatch empowers utilities to modernise substations, reduce risk and optimise network performance, both today and into the future.

For utilities seeking a practical and scalable path toward smarter grids, GridWatch is more than a monitoring solution.

It is a strategic asset.
