Energy and Mines Minister Joel Santos visited Washington, D.C., to lead discussions on critical mineral supply chains and cross-border energy infrastructure. The initiatives focus on the potential for rare earth elements in the Dominican Republic and a proposed submarine electrical connection with Puerto Rico.
Why it matters
Regional efforts to secure critical mineral supplies and integrate electricity markets are gaining momentum. The discussions highlight a growing push to bolster energy security through international cooperation between Caribbean neighbors and global partners.
The Caribbean Transmission Development Company has proposed a submarine electrical cable with a capacity of 700 megawatts. This infrastructure would span the Mona Passage to connect the electrical grids of the Dominican Republic and Puerto Rico.

Timeline
Dominican Week 2026 took place in Washington, D.C., during September 2026.
Market Landscape
The push for regional energy infrastructure follows the pattern set by the U.S.-Dominican Republic cooperation framework for critical mineral supply chains. These developments signal a broader shift toward securing local resource independence while integrating Caribbean power markets against global economic volatility.
The potential integration of electricity markets could eventually lead to more stable power supplies for the region. However, these are early-stage industrial proposals that do not currently alter local utility rates or consumer access.
The takeaway
Large-scale energy and mining projects require long-term international coordination to reach viability. Readers should note that while these discussions are high-profile, physical infrastructure implementation in the energy sector typically spans several years or even decades.
