Corinex Unveils Grid Intelligence Node to Transform Low-Voltage Energy Networks

On August 24, 2026, Corinex, a leader in network intelligence and digital reinforcement for low and medium voltage distribution networks, introduced the highly anticipated Grid Intelligence Node (GIN). This innovative system is set to revolutionize how electric utilities monitor and manage low-voltage grids by providing near real-time measurements and event detection.

The Need for Enhanced Low-Voltage Monitoring

The electrification of infrastructure is generating new demands on low-voltage networks. Utilities are facing challenges in identifying and predicting limitations within these systems. Sam Shi, the Chief Technology Officer at Corinex, highlighted the urgent need for better monitoring solutions, as utilities often lack the necessary information to detect or foresee potential issues. The GIN addresses this gap in knowledge by delivering accurate insights into the true state of the low-voltage grid.

Key Features of the GIN

The Grid Intelligence Node incorporates advanced functionalities that empower electric utilities. Some of the major technical capabilities include:

• - High Precision Measurements: The system offers three-phase voltage and current measurements with an RMS error of less than 0.5%.
• - Comprehensive Power Metrics: It monitors power, power factor, frequency, and energy consumption, providing a holistic view of grid performance.
• - Harmonic Analysis: The GIN can detect harmonics up to the 51st order and total harmonic distortion, which is crucial for maintaining power quality.
• - Event Detection: The device identifies voltage sags and swells, overloads, and phase imbalances, enabling proactive management of grid conditions.
• - Data Aggregation: Operational snapshots are available every minute, with energy aggregation over 15 minutes, which aids in prompt analysis.
• - Robust Connectivity: The device supports connection to 230/400 V networks and transmits data using MQTT protocols.
• - Environmental Resilience: With a temperature range of -25 °C to +70 °C and an IP67-rated housing, the GIN is built to withstand challenging environmental conditions.

These features enable utilities to have a clearer understanding of load and operating conditions across their low-voltage networks, ultimately enhancing their ability to manage and optimize operations effectively.

Integration with Existing Infrastructure

One of the standout advantages of the GIN is its compatibility with existing low-voltage infrastructure. It integrates seamlessly with Corinex's broadband over power line (BPL) technology, allowing for the transmission of energy quality and measurement data without the need for extensive network overhauls. This practicality is especially beneficial for utilities looking to modernize their systems without incurring substantial costs.

The GIN also communicates with Corinex's Plexigrid Intelligence platform, enabling near real-time connection of field data with advanced network modeling and optimization. This integration facilitates the creation of more accurate digital twins of the grid, resulting in better state estimation and network modeling.

Benefits for Utilities

The enhanced visibility provided by the GIN allows utilities to:

• - Improve low-voltage state estimation and model accuracy.
• - Evaluate available capacities for electric vehicles, heat pumps, and photovoltaic systems.
• - Determine whether limitations should be addressed through flexibility or physical reinforcement.

As electrification continues to grow, having access to precise, real-time data becomes increasingly vital. The GIN’s ability to base its models on near real-time physical measurements aids utilities in understanding available capacity and making informed decisions. Sam Shi emphasized that “digital twins are only as reliable as the data that underpins them.” Therefore, the GIN represents a major step forward for utilities striving to keep pace with the demands of modern energy distribution.

Conclusion

The Grid Intelligence Node by Corinex offers electric utilities a practical and efficient way to enhance their low-voltage visibility using existing infrastructure. Designed specifically for modernization efforts, this innovative node combines high-performance broadband communication with advanced measurement capabilities.
Ready for evaluations, pilot projects, and commercial implementations, GIN sets the stage for a smarter, more reliable future in energy distribution. For more details about Corinex and the Grid Intelligence Node, visit www.corinex.com.
