The Dominican Republic has started operating the Cotoperí Solar complex, which is now the largest solar power plant in Central America and the Caribbean. It has a capacity of 162.6 MW. The project was launched in a ceremony led by Vice President Raquel Peña.

The plant  in Guaymate, in La Romana province was built by the Spanish company Acciona Energía together with local investors. The complex is actually three solar plants combined. Acciona Energía owns 51%, while the remaining 49% belongs to Cotosolar Holding. That group includes the JMMB Sustainable Energy Fund, Grupo Pais, and several others.

A press release said the project includes several community programs. These include job training, small-business support, road safety classes, and a job bank that gives priority to local people. More than 3,500 people have benefited so far.

The project also supports water and sanitation improvements in two neighborhoods, working with Centro Arcoíris and acciona.org. These upgrades help more than 4,500 residents.

Cotoperí Solar is part of a wider renewable energy push. Acciona Energía also opened the Calabaza I solar plant in June 2025. It has a capacity of 58 MW, enough to power about 54,000 homes.

Another plant, Pedro Corto, is being built in San Juan de la Maguana province. It will have a capacity of 63.35 MW and is expected to produce 189.07 GWh each year. It has a long-term power purchase deal with the utility Edesur Dominicana.

Acciona Energía and acciona.org also signed agreements in May 2025 with the Ministry of Energy and Mines to bring clean energy to vulnerable communities.

Grupo Pais and the JMMB Sustainable Energy Fund plan to keep investing in renewable energy. Together, their projects already add up to more than 710 MW of installed capacity.
