On January 15, 2025, as part of the Telecommunications Systems curricular unit, students from the Bachelor's Degree in Electronics, Telecommunications and Computer Engineering and the Bachelor's Degree in Informatics, Networks and Telecommunications Engineering carried out a study visit to the Network Operations Center (NOC) of REN's Security Telecommunications Network,  located in Sacavém. This centre plays a central role in the management and monitoring of the transmission network and private voice network layers, which are considered critical to ensure the safe and efficient operation of the national energy infrastructure.

During the visit, REN officials presented the telecommunications network that supports the company's entire operation, explaining its importance as a critical network for the continuous operation of energy transmission networks. The students also had the opportunity to observe, in real time, the monitoring carried out at the NOC, understanding the tools and processes involved in overseeing communications.

The visit also included a visit to the technical room, where various equipment that is part of the national transmission network was presented. This experience allowed students to consolidate the knowledge acquired in the classroom, reinforcing the connection between theoretical content and its practical application in large-scale infrastructures.

This activity demonstrated the value of synergies between educational institutions and leading companies in the sector, providing students with an in-depth and concrete view of the challenges and technological solutions that define critical telecommunications.
