Executive Summary
ENGIE faced a steady increase in theft along their transmission lines. These events created operational risks, extra costs, and exposure for on-site crews.
To address the threat, ENGIE deployed SENTRI sensors on vulnerable sections, using continuous monitoring and georeferenced alerts.
The system improved early sabotage detection and supported faster coordination with internal teams and police forces. When an incident is reported, alerts now enable a rapid response, with police reaching the site within approximately 15 minutes. This has strengthened the operational protection of the infrastructure.
The Challenge
Cable theft became a recurring issue in the region, affecting critical sections.
The impact was clear:
- Direct risks for maintenance teams
- Economic losses
- Lower availability and supply stability
- No early visibility of sabotage attempts
ENGIE needed a reliable, continuous, adaptable system to detect abnormal activity in remote areas, even when lines were de-energized.
