Equatorial Group is boosting power grid security by expanding its use of nanotechnology, innovating in the fight against cable theft and strengthening asset traceability across its operations.
The Equatorial Group, one of the leaders in the Brazilian power sector, is raising the bar for security within its electrical infrastructure. The company has announced the expansion of its use of nanotechnology, a sophisticated strategy to identify and track grid components in an effort to combat the growing problem of cable theft and the subsequent illegal resale of materials.
This initiative, which began implementation in Rio Grande do Sul in January 2026 following a study period that started in March 2025, has already covered more than 3 kilometers of power cables and substation grounding systems. The adoption of this cutting-edge technology marks a milestone in the company’s fight against criminal activity, promising greater resilience and stability in energy supply.
Cutting-Edge Technology in the Fight Against Crime
The innovative solution uses microparticles with a unique identification signature, integrated directly into the materials. This feature allows the origin and ownership of assets to be verified quickly using specific reader equipment.
The goal is clear: to reinforce the traceability of each component and provide crucial evidence for investigations conducted in partnership with law enforcement. By making assets unmistakable, Equatorial makes it difficult for criminals to operate and sell these materials illegally.
Promising Early Results
In Rio Grande do Sul, where nanotechnology was pioneered, preliminary results are encouraging. Since operations began, the Equatorial Group has carried out 38 actions to combat asset theft, which resulted in 43 police reports and the recovery of approximately 1.48 tons of cables.
During the same period, the utility recorded an impressive 55% drop in theft incidents compared to the previous year. The company attributes this improvement to a comprehensive set of measures, including intelligence, enhanced security, technological innovation, and coordinated efforts with public security agencies, rather than relying solely on nanotechnology.
“Innovation is a vital ally for Equatorial in protecting infrastructure essential to society. By using nanotechnology to expand the identification and traceability of our assets, we strengthen our prevention and investigation capabilities and contribute to even more integrated operations with law enforcement. It is a solution that combines technology, intelligence, and security to protect our assets and, consequently, the continuity of the service provided to our customers.”
Johnathan Costa, Business Security Manager at Equatorial Group.
Future Vision and Expansion
Currently, the nanotechnology is operational in Rio Grande do Sul and is in the process of expanding to Maranhão. The company’s goal is to extend this strategic tool to all Equatorial Group distribution companies by 2028.
The next phase of the project involves front-loading the identification of materials by applying the technology directly at Distribution Centers, even before the cables and equipment are sent to warehouses and later installed in the field. This measure will improve traceability throughout the entire asset lifecycle, ensuring they are linked to the company from the point of origin.
This robust approach complements existing asset protection mechanisms at Equatorial, consolidating an integrated system to confront the theft of materials. The crime of stealing copper cables not only causes damage to electrical infrastructure and power outages, but also fuels an illegal trade network.
Mechanisms such as nanotechnology provide crucial information for the efficient recovery of materials and the investigation of incidents, protecting the quality of service provided to the public and contributing to national energy security.
