The Dominican Electricity Transmission Company (ETED) has announced a series of planned maintenance operations targeting critical transmission infrastructure this weekend. As part of its ongoing infrastructure enhancement initiative, ETED will perform essential upgrades on two major 69 kV transmission lines serving industrial and residential areas.
On Saturday, March 14, maintenance crews will focus on the Arroyo Hondo – Capotillo transmission line between 10:00 am and 2:00 pm. The work involves replacing two 65-foot wooden poles situated directly in front of the Arroyo Hondo – Capotillo substation. This operation will temporarily affect power supply to several major industrial facilities including Molinos Modernos, Mercasid, Petroquímica, Polyplas, Termopac, and Smurfit Kappa.
A second maintenance window is scheduled for Sunday, March 15, targeting the 69 kV Boca Chica – San Pedro de Macorís (Cementos) line from 9:00 a.m. to 2:00 p.m. This intervention will include comprehensive preventive maintenance at the substation alongside the replacement of critical insulator components. The work will result in temporary service interruptions for the communities of Guavaberry and Cayacoa, as well as for industrial operations at César Iglesias, Destilería Brugal, and Harinas del Higüamo.
ETED officials emphasized that these scheduled interruptions represent strategic investments in grid reliability rather than emergency repairs. The maintenance program is designed to proactively strengthen transmission infrastructure, prevent unexpected breakdowns, and ensure long-term service stability across the National Interconnected Electrical System (SENI). The company’s preventive approach aims to minimize future disruptions while enhancing the overall resilience of the nation’s power grid.
