The proposal was presented last week
Caribbean Transmission Development Co. (CTDC) confirmed Tuesday it has formally submitted an unsolicited proposal to the Puerto Rico Public-Private Partnerships Authority (AAPP) for the development of the Hostos Project, an international energy infrastructure initiative that would link Puerto Rico and the Dominican Republic through a high‑voltage direct current (HVDC) subsea interconnection.
The filing, delivered on May 14, was submitted under the legal framework established by Puerto Rico’s Public-Private Partnerships Act (Law 29‑2009) and the Electric System Transformation Act (Law 120‑2018), according to a company statement.
The CTDC said the proposal aligns with the federal Presidential Permit authorizing the construction, connection, operation, and maintenance of an international electric interconnection.
The multibillion-dollar Hostos Project envisions an HVDC submarine cable of up to 700 MW between the two islands, paired with new, modern generation capacity dedicated exclusively to Puerto Rico. The company says the initiative is designed to strengthen the island’s grid reliability, resilience, and operational flexibility by providing access to external energy resources.
CTDC noted that the submission follows several years of technical, environmental, and regulatory work before U.S. and Dominican authorities, including securing the federal authorization required for cross‑border energy infrastructure.
“The Hostos Project represents a unique international energy infrastructure asset within Puerto Rico’s electric system, designed to provide access to external energy resources that will enhance the resilience and capacity of the Island’s grid through a federally authorized interconnection and contribute to the modernization of our electric network,” the company said in written statements.
The developer added that the project is in an advanced stage of technical and regulatory development, having completed specialized processes typical of international transmission projects of this scale.
CTDC emphasized that its proposal to the AAPP strictly follows the mechanisms established by the Puerto Rico government for evaluating energy infrastructure initiatives and public‑private partnerships. The company said it will not comment further on the proposal’s content or merits while the administrative review is underway, except as required by the process.
“CTDC will continue collaborating with the relevant agencies and entities in accordance with the processes established by law and in compliance with all applicable regulatory requirements,” the company stated.
The P3 Authority did not immediately answer requests for comment.
