Enel Distribución continuously works to reduce the impact of extreme weather events on electricity networks. Additionally, in preparation for winter, extra measures are implemented each year to minimize disruptions to customers caused by wind, rain, or storms.
These are the measures and their progress as of July 31, 2025:
Training and expansion of crews
Enel Distribución has increased the number of crews to over 365 operational resources in preparation for winter. In implementing this initiative, it is important to highlight the inclusion of heavy crews and energized lines for major works, pruning and/or felling crews, and the conversion of multi-purpose crews to handle low-voltage network failures, field damage assessors, and personnel responsible for direct installation in the field.
Additionally, at the Enel Group level, teams from other countries have been trained to form a specialized group for operational emergencies at the regional level. Participating countries include Colombia, Brazil, Argentina, Italy, and Chile. Knowledge sharing ensures compliance with local regulations and maintains each country's technical and safety standards. This also includes a virtual warehouse stocked with materials and equipment approved by the different countries.
Additionally, different authorities have taken part in a series of role-specific training sessions and emergency drills.
Network Capacity
Strengthening the network by implementing projects in 20 medium-voltage infrastructures, known as feeders, which are electrical arteries that reinforce the city's distribution system.
Remote control system for the medium-voltage network
This technology greatly reduces downtime during outages through remote operation. By July 2025, over 460 new remote-controlled devices have been installed in the medium-voltage network, increasing the total to more than 3,240.
Aerial inspection of electrical networks
Between December 2024 and January 2025, inspections were conducted using drones and helicopters over 2,500 kilometers of medium-voltage overhead lines. This type of inspection enables the early detection of critical points in the network. In addition to high-resolution images, LIDAR (Light Detection and Ranging) technology is used, which provides a three-dimensional reconstruction of the infrastructure.
Pruning Strategy
This consists of clearing vegetation near the networks, preventing faults caused by trees or branches falling on the power lines. As of July 2025, the company's specialized crews had pruned and/or felled more than 102,000 trees in the safety zone, minimizing the risk of interference with our networks and reducing the likelihood of faults caused by contact or falling vegetation.
Backup generators: We have hired a fleet of generators, which, combined with our own, gives us over 95 units of various capacities for emergencies.
Municipal crews' training
At its Center of Operational Excellence, Enel Distribución trains municipal crews on electrical networks and energy. The initial sessions included the municipalities of Vitacura and Lo Barnechea, whose teams visited the company's facilities to learn how the infrastructure functions and to encourage teamwork in the field, especially during emergencies.
Delivery of backup equipment for people dependent on electrical power devices: At the end of July, we provided 2,776 permanent backup devices, representing 87% of the electro-dependent patients documented in our records.
Enhancing customer service and information platforms:
WhatsApp customer service channels have expanded fivefold, capable of handling up to 50 messages per second. Meanwhile, a 25% increase has been added to the Call Centre customer service lines.
