With an investment amounting to RD$ 649,154,324, Edesur Dominicana is developing an intensive optimization plan for the distribution network in several provinces within its concession area.
The interventions will benefit more than 550,000 customers in about 179 sectors of the National District, Santo Domingo Oeste, Los Alcarrizos, Pedro Brand, San José de Ocoa, Barahona, and Independencia.
The works include the construction of new medium-voltage circuits, the reconductoring and reconfiguration of the distribution network such as strategic interconnections between circuits and load transfer, construction and adjustments of networks, among other actions.
The program covers seven projects in Greater Santo Domingo, with an investment exceeding RD$39.2 million that will benefit more than 465,000 users in some 105 sectors, including Urbanización Fernández, Yolanda Morales, Piantini, Evaristo Morales, Los Jardines, Los Ríos, Villa Marina, El Millón, La Julia, Quisqueya, La Yuca (Piantini), Bella Vista (center and north zone), Mirador Norte, Mirador Sur, and the University Zone.
In addition, Atala, Ciudad Nueva (west), San Carlos, Los Prados, La Castellana, El Milloncito, Cristo Rey, El Caliche, Ensanche La Fe, Villa Juana (west), Arroyo Hondo Viejo, Renacimiento (north), Alameda, Los Peralejos, Los Girasoles, Carmen Renata III, Pantoja, Villa Aura, Las Caobas, Herrera, Don Honorio, La Pared de Haina, Hato Nuevo, among others.

Among the adjustments made in the National District as part of this plan is the enablement of two new medium-voltage feeders: PARA107 and PARA108, at the Paraíso electrical substation, which allows for a reduction in demand on that infrastructure and others nearby such as Los Prados, Embajador, and Arroyo Hondo.
In that area, more than 43,000 customers, from about 10 sectors of the capital, are already benefiting from improvements in voltage, stability, and reliability, because the distributor will have an operational margin of over 30%.
Meanwhile, at the Matadero electrical substation, the new MATA107 circuit has entered service, which allows for dividing the energy load of the MATA104 circuit and reducing the demand on the MATA103. These improvements, which contribute to the electrical stability of seven sectors, positively impact approximately 24,500 users.

Another project being considered is the construction of a new circuit, the UASD108, at the UASD 138 kV Substation, which will allow for the redistribution of energy load, reducing the overload on the UASD104 circuit. With the new circuit, more than 5,000 users across about seven sectors will have a more stable service.
Also, the reconfiguration of the distribution network is planned through the partial load transfer between several circuits belonging to the Hato Nuevo, Cabayona, DISDO, Zona Franca de Los Alcarrizos, Herrera Nueva, Herrera 138 kV, Kilómetro 10 ½ de la Autopista Duarte, Los Prados, and Centro de Operaciones de Herrera electrical substations.
Such works will contribute to the reduction of overload risk in critical circuits, to improving voltage profiles, reducing technical losses, and strengthening system operation during periods of high demand.
Other interventions
The Distribution Network Optimization and Improvement Projects planned for 2026 also include the Las Damas substations, in Duvergé, Independencia; Vicente Noble, in Barahona, and San José de Ocoa.
More than 257,000 users in Greater Santo Domingo have already benefited from significant system improvements due to the adaptation and commissioning of the Alfa electrical substation, as well as more than 21,000 users supplied by the Kilómetro 10 ½ of the Duarte Highway, Herrera 138 kV, Los Prados, and Herrera substations.
Likewise, work has been carried out at the Rancho Arriba substations, in San José de Ocoa; Jimaní, in Independencia and Pedernales, which have contributed to improving the efficiency of the supply to thousands of customers.
