In a major step forward for Dominican Republic’s electrical infrastructure upgrade, state-linked utility provider Edesur Dominicana has launched the logistics process to transport six newly manufactured power transformers from China to its domestic concession network. The project, backed by a total investment of RD$469.8 million, is a core component of the company’s long-term strategy to modernize aging grid infrastructure and deliver more consistent, reliable power service to end users across its service territory.
The acquisition of the transformers followed a competitive public bidding process, which ultimately awarded the supply contract to local firm Electroval. The new units come in three distinct capacity ratings: 30, 40, and 50 megavolt-amperes (MVA), engineered to operate at two standard voltage configurations: 69/12.8 kV and 138/12.8 kV, tailored to fit seamlessly into the Dominican Republic’s existing distribution network. Utility planners project that adding these high-capacity transformers will significantly boost the company’s ability to accommodate growing peak electricity demand, while also reducing the risk of distribution outages and improving overall grid stability for residential, commercial, and industrial customers.
To guarantee that every unit meets strict technical specifications and global quality benchmarks, a dedicated technical delegation from Edesur traveled to Zhejiang Province, the manufacturing hub in eastern China, to carry out comprehensive Factory Acceptance Tests (FAT) and on-site inspections prior to the equipment’s shipment. According to official statements released by Edesur, all six transformers have passed these rigorous assessments, fully complying with both international industry regulations and the specific operational requirements set out by the utility. This injection of new capital and equipment forms part of a broader national initiative to upgrade the Dominican Republic’s power system, with the overarching goals of boosting operational efficiency, increasing long-term sustainability, and strengthening the grid’s resilience against unexpected disruptions.
