Proactive risk management is a cornerstone of operating a stable, consistent national power grid, and infrastructure operators in the Dominican Republic are taking tangible action to uphold system reliability this month. The Dominican Electric Transmission Company (ETED) has announced it will execute targeted structural replacement work on the 69 kV Haina-Herrera Nueva-Metropolitano L3 transmission line this Saturday, August 29. This planned intervention is designed to replace aging, degraded components that have deteriorated over time, ensuring the critical infrastructure retains safe, functional operating conditions for years to come.
The maintenance work is scheduled to run from 8:00 a.m. local time through 2:00 p.m. the same day. To complete the upgrades safely, ETED will need to temporarily cut electrical service to a broad swath of residential and commercial areas across the country’s capital region. Impacted residential neighborhoods include El Millón, Los Prados, Quisqueya, Los Restauradores, Bella Vista, Mirador Norte, Piantini, La Julia, Ensanche Naco, Ensanche Kennedy and La Fe. A number of major local institutions and businesses will also see full service interruptions during the work window: these include telecom provider Claro Dominicana, Banco Popular, retail group Haché, leading newspaper Listín Diario, medical center CEDIMAT, agricultural firm MAPRICA, publisher Publicaciones Ahora, and the Plaza de la Salud medical complex. Two additional businesses, Torginol and Flexible Plastic, may also experience partial or intermittent service effects while the work is ongoing.
This targeted upgrade is not an isolated project, but part of ETED’s ongoing, systematic program of preventive maintenance across the country’s entire transmission network. By regularly inspecting, repairing, and replacing aging components across its lines and supporting structures, the company works to head off unplanned outages, mitigate systemic safety risks, and consistently strengthen the overall reliability of the Dominican Republic’s electrical service for all users.
In its public announcement of the work, ETED expressed gratitude to residential and commercial customers for their patience and understanding during the temporary interruption. The company also reaffirmed its long-term commitment to expanding and upgrading the national electricity transmission network, which serves as a foundational enabler for the Dominican Republic’s ongoing energy transition and digital transformation goals.
