The Hostos Project is a significant initiative focused on energy sustainability between the Dominican Republic and Puerto Rico. The project entails the construction of a submarine cable from the east coast of the Dominican Republic to Puerto Rico, specifically Mayagüez. It also includes the establishment of a solar plant and a green hydrogen plant on the Dominican side, along with two converter stations—one in each country. The primary goal of the Hostos Project is to provide an efficient, cost-effective, and sustainable solution to the energy challenges faced by both islands by interconnecting their power grids through a high-voltage submarine cable (HVDC). This project is designed to enhance the grids of the Dominican Republic and Puerto Rico, ultimately meeting approximately 20% of Puerto Rico's energy requirements. Moreover, it will facilitate the development of a two-way energy market, enabling the exchange and trade of excess energy between the two islands. This initiative not only addresses energy needs but also opens up avenues for economic growth and investment opportunities. Key companies involved in the project include Usina de Energia Fotovoltaica Hélio Valgas I Ltda, Geradora Solar Hélio Valgas V S.A., and Verano Capital Holding SpA, among others. These companies are instrumental in the development and investment in renewable energy projects, highlighting the project's focus on sustainable energy sources. The Hostos Project represents a crucial step towards a more sustainable and interconnected energy future for the Dominican Republic and Puerto Rico. Its vision of enhancing energy security, promoting renewable energy sources like solar and green hydrogen, and fostering economic cooperation through energy exchange sets a positive trajectory for the region's energy landscape.
