WASHINGTON, United States (CMC) — The Trump administration has approved the presidential permit required for the construction of a submarine power cable connecting Puerto Rico and the Dominican Republic, marking a major step forward for one of the most ambitious energy projects in the Caribbean.

Although the United States (US) Department of Energy (DOE) has not yet issued a formal notification, the Caribbean Transmission Development Company (CTDC) confirmed it has already received “no objection” clearances from the US Departments of State and Defense.

A public announcement is expected in mid-February.

According to CTDC President Rafael Vélez Domínguez, the official announcement is scheduled for February 17 in the Dominican Republic and is expected to be attended by Dominican President Luis Abinader, Puerto Rico Governor Jenniffer González and representatives of the US government.

While the DOE website still lists the permit application as “pending”, Vélez Domínguez said the company is preparing to move forward once the federal process is formally completed, including issuing purchase orders for the submarine cable.

The project would allow the transmission of up to 700 megawatts of electricity in both directions, strengthening energy security in both territories.

In the Dominican Republic, the cable would connect to a new natural gas power plant developed exclusively for the project, while in Puerto Rico, it would link to the electrical grid through the Mayagüez substation. CTDC must still finalise power purchase agreements with the Puerto Rico Electric Power Authority (PREPA), secure fuel supply contracts, obtain environmental and regulatory approvals in both jurisdictions, and raise an estimated US$2.5 billion in financing.

CTDC aims to energise the cable by January 2031. Initially, the project is expected to supply part of Puerto Rico’s energy demand, but in the long term, it could also facilitate the export of surplus solar energy from Puerto Rico to the Dominican Republic.

If completed, the initiative would become the first electrical interconnection in the Caribbean, joining more than 160 similar cross-border power links already operating between the United States, Canada and Mexico.
