CIRCE brings to ENLIT Europe 2025 its technological proposal to accelerate the digitalization of power grids

The future of the power system lies in being smarter, safer, and more connected. With this goal in mind, CIRCE will take part in ENLIT Europe 2025, the major European meeting point for the energy sector, to be held in Bilbao from 18 to 20 November. The centre will showcase how technology can make power grids more reliable, efficient, and resilient.

During the event, the technology centre will demonstrate how applied innovation and digitalisation are transforming the operation of electrical grids, making them safer, more efficient, and more resilient. Its approach combines applied research, accredited validation, and industrial experience, helping utilities, manufacturers, and grid operators address the challenges of the energy transition.

Demonstrations of IEC 61850 Digital Substation

At its exhibition space, CIRCE will showcase two devices from the Advanced IEC 61850 Test Tool for Digital Substations, a platform developed to validate, monitor, and test digital protection and control systems.

The live demonstrations will show how the tool reproduces real grid conditions and simulates electrical events, analysing in real time how the system responds.

This technology reduces testing costs, accelerates commissioning, and improves equipment interoperability in digital substations.

The four pillars of CIRCE’s technological proposal

CIRCE’s presence at ENLIT will revolve around four innovation areas that are redefining the way electrical networks operate. Four solutions sharing the same purpose: optimising energy asset management and strengthening system security.

1. Electrical fault detection and location (TDR)

Through the Time Domain Reflectometry (TDR) technique, CIRCE has developed a tool capable of pinpointing the exact location of a fault or cable degradation without interrupting service.

The system can detect breaks, defective joints, or overheating in seconds, significantly reducing diagnosis time and maintenance costs.

2. Virtualisation of protection and control systems

Digital substations require increasingly complex validation environments.

CIRCE will demonstrate how IEC 61850 virtualisation enables testing of protection and control systems without physical hardware, accurately replicating grid behaviour under various conditions.

This approach enables faster development, reduced risks, and improved interoperability among manufacturers.

3. Industrial cybersecurity

Digitalisation is only viable if it goes hand in hand with security.

CIRCE will present its cyber maturity assessment tool for energy systems, aligned with the NIS2 Directive and the National Security Framework (ENS).

This solution helps identify vulnerabilities, prioritise actions, and reinforce the resilience of critical infrastructures against cyberattacks.

4. Power quality

A modern electrical grid must be not only continuous but also stable and predictable.

CIRCE will present its power quality monitoring solutions, capable of measuring the stability and “purity” of electricity.

These tools identify harmonics, imbalances, and disturbances that affect equipment efficiency and facility performance, thereby enhancing supply reliability.

CIRCE Talk + Coffee: demonstrations, talks, and networking

In addition to the technological demos, CIRCE will offer within its stand an open space for knowledge exchange and dialogue: “CIRCE Talk + Coffee”.

Throughout the three days of the event, short and practical sessions will be held, allowing visitors to discover CIRCE’s most innovative projects first-hand.
