Santo Domingo’s primary electricity distributor, Edesur Dominicana, has initiated a comprehensive RD$155 million (approximately US$2.6 million) modernization project to significantly enhance its power infrastructure. This strategic investment targets critical upgrades across ten major substations—including Paraíso, UASD 138 kV, Herrera, and Bayona—while deploying new distribution lines to manage escalating electricity consumption during high-demand periods.
The initiative specifically aims to reduce technical energy losses, which currently range between 10% and 17% in affected circuits. Key engineering enhancements involve installing additional transformers, establishing new medium-voltage transmission lines, and substantially increasing substation capacities. Notable technical improvements include a 10-14 MVA transformer at Herrera’s operational hub and a new 40 MVA Alfa substation designed to redistribute approximately 25.9 MVA of electrical load from overburdened network segments.
Approximately 400,000 customers across 70 communities in Santo Domingo and the National District will benefit from these infrastructure improvements. The project focuses on enhancing distribution stability and reducing prolonged outage risks, particularly during the upcoming summer months when cooling demand peaks.
This substantial investment marks a strategic shift from reactive maintenance to proactive infrastructure development. By modernizing its grid architecture, Edesur not only addresses immediate service reliability concerns but also establishes a scalable foundation for future energy demands aligned with the country’s urban expansion and economic growth trajectory.
