• As part of Enel Distribución and Enel Trasmisión's Winter Plan, efforts have focused on preventive measures to reduce supply interruptions during weather emergencies and lower their impact on 1,500 kilometers of network.

Santiago February 17, 2022.- We have equipped drones, vans, and a helicopter with state-of-the-art technology to detect vulnerable points in Enel Distribución's and Enel Transmisión's electricity system. The technology seeks to monitor 1,500 kilometers of high and medium voltage networks in thirty-nine municipalities of the Metropolitan Region.

The purpose of this inspection is to identify places in our distribution and transmission network that require special attention and, based on the information we gather, execute a preventive maintenance plan, such as clearing trees that may affect distribution and transmission lines during the coming winter.

The technology used in the inspection is efficient and accurate in its maintenance task with minimum impact on the environment.

This project involves aircraft overflights in inspection zones that comply with all the regulations and authorizations required by the General Directorate of Civil Aeronautics (DGAC) with little to no inconvenience for neighbors. The overflight trajectory will always be over the power line site. The equipment scanning the distribution network will not capture images of private property, respecting the community's privacy.

The overflights began on February 14 and will be conducted between 8:00 a.m. and 8:00 p.m. from Monday to Friday and on Saturdays from 8:00 a.m. to 2:00 p.m. to conduct the electric network's diagnosis and subsequent preventive maintenance. These actions will improve the company's service. Enel Distribución and Enel Transmisión hope to avoid the drawbacks caused by, for example, vegetation growth in sectors where this is a major cause for service interruption.

Information channels

During the aerial inspection period, customers and users will have access to all the necessary information, like the days and places where the aircraft will fly. To do so, they can consult the company's contact channels, such as Fono Servicio (600 696 0000), enel.cl, website, Twitter account @EnelClientesCL and Facebook “EnelChile."
