The Dominican Republic has inaugurated Cotoperi Solar, a 162.6 MWp photovoltaic complex now recognized as the largest solar installation in Central America and the Caribbean. The project, located in Guaymate, La Romana, was officially opened by Vice President Raquel Peña, Solar Quarter reports.
The main shareholder of the project is Spain’s Acciona Energía with a 51% stake. The remaining 49% is owned by Cotosolar Holding, which includes the JMMB Sustainable Energy Fund (FES), Grupo País, and other minority investors.
The ceremony was attended by Minister of Energy and Mines Joel de los Santos, Acciona president José Manuel Entrecanales, JMMB Dominican Republic executive president Juan José Melo, and Grupo País CEO Juan Carlos País.
Comprising three interconnected solar plants, Cotoperí Solar is expected to generate 286 GWh of clean electricity annually, avoiding more than 210,000 tonnes of CO₂ emissions, equivalent to planting 5.5 million trees.
The construction phase created more than 600 direct and indirect jobs, providing a significant boost to the local economy. In parallel, the project has launched multiple community development initiatives, benefiting more than 3,500 residents near the site through employment programs, training in technical and entrepreneurial skills, and road safety campaigns.
In partnership with the local organization Centro Arcoíris and the acciona.org foundation, Cotoperí Solar is also supporting improved water and sanitation access in the Bella Vista and Villa Penca neighborhoods of Bajos de Haina, positively impacting over 4,500 people.
Cotoperí Solar is Acciona Energía’s second solar project in the Dominican Republic, following the commissioning of Calabaza I (58 MWp) near Bani in Peravia province in 2023. The company is also constructing the Pedro Corto solar plant in San Juan de la Maguana (82.69 MWp) with Grupo País, strengthening its renewable portfolio in the country.
As reported, Grupo País and the JMMB Sustainable Energy Fund continue to scale their renewable energy investments in the Dominican Republic, now surpassing 710 MWp of installed capacity.
Beyond renewable energy, Acciona is advancing major infrastructure projects, including the Eastern Aqueduct of Santo Domingo, set to improve water supply for 850,000 people, and the runway of the Cabo Rojo International Airport in Pedernales.
