AssetCool Hosts Landmark Multi-TSO Demo Day with Red Eléctrica in Seville, Showcasing Live Deployment of Capacity-1 Platform

11 February, 2026

Seville, Spain

AssetCool, the grid robotics and advanced coatings company accelerating speed-to-power for transmission networks, successfully hosted a landmark multi-TSO Demo Day in Seville with Red Eléctrica, Spain’s Transmission System Operator. The event was held in collaboration with Elewit, Red Eléctrica’s innovation platform and corporate venture arm.

The gathering brought together senior representatives, innovation leads, and technical teams from leading European TSOs, including ELES (Slovenia), Elia (Belgium), Terna (Italy), and RTE (France), among others. The event provided a rare opportunity for multiple transmission operators to witness a live deployment of AssetCool’s Capacity-1 platform on an operational transmission asset.

Demo Days as catalysts for applied innovation

Designed as more than a technology showcase, the Demo Day served as a collaborative forum where participants could evaluate an innovative solution under real operating conditions. This type of initiative enables TSOs to assess technical and operational fit, exchange perspectives on common challenges and identify potential opportunities for future collaboration.

Real-world validation to accelerate technology adoption

The day began with a strategic session in central Seville, where AssetCool presented global validation data, operational learnings, and the commercial maturity of the Capacity-1 platform, which served as a theoretical foundation for the following demonstration on field. 

In the afternoon, attendees travelled to the field site where AssetCool’s robotic platform and advanced photonic coating technology were deployed in real time on the Red Eléctrica network. In order to demonstrate AssetCool’s technology, six robotic units operated in parallel, applying the coating across multiple transmission spans. During the next months, the goal will be to validate the capacity increase by comparing it with other technologies.

Participants were able to observe the full operational workflow, from installation and system setup to execution and monitoring, and engage directly with the technology. Utility engineers and field teams engaged directly with the equipment, asking detailed operational questions and evaluating integration into standard grid maintenance practices.

The demonstration showcased the safety, simplicity, and operability of the robotic system in real-world conditions.

A collaborative space for utilities and technology providers

A key outcome of the Demo Day was the creation of a shared space for peer-level dialogue among European TSOs, technology providers and industry stakeholders. By convening multiple operators at a single operational site, the event facilitated discussion around common challenges such as thermal constraints, climate-driven infrastructure stress and the need to accelerate grid modernization across Europe.

This collaborative model reinforces the role of Demo Days as a starting point for future pilot projects, proof-of-concepts and longer-term collaborations, helping to validate emerging technologies and accelerate their introduction into the electricity system.
