ACCIONA Energía today announced the construction of three battery energy storage systems (BESS) in the Dominican Republic, with commissioning planned for the last quarter of 2027.
The projects will have a combined capacity of 21.2 MW and an aggregate storage capacity of 41.7 MWh. They will be located next to the Pedro Corto, Calabaza, and Cotoperí photovoltaic plants, allowing for the use of existing infrastructure, reducing the need to occupy new land, and optimizing investment costs.
The new batteries will contribute to improving the stability of the National Interconnected Electric System (SENI). Thanks to their virtually instantaneous response capacity, they will help correct frequency deviations and facilitate the integration of a greater amount of renewable energy.

This initiative reflects the evolving regulatory framework in the Dominican Republic, which is increasingly favoring the use of batteries to help maintain the stability of the electrical grid. Furthermore, the decreasing costs of this technology are making it an increasingly competitive alternative to traditional solutions.
For ACCIONA Energía, these new projects also represent an opportunity to increase the value of its existing assets in the Dominican Republic, where it already has three photovoltaic installations totaling 303.3MWp: Calabaza I (58MWp), Cotoperí Solar (162.6MWp) and Pedro Corto (82.7MWp).
Both Cotoperí Solar and Pedro Corto have been developed in collaboration with local partners. In Cotoperí Solar, ACCIONA Energía holds a majority stake of 51%, while the remaining 49% belongs to Cotosolar Holding, which includes the JMMB Sustainable Energy Fund (FES), managed by JMMB Funds, Grupo Pais, and other minority investors. Similarly, in Pedro Corto, ACCIONA Energía also owns 51% of the capital, and the Pioneer II Social Impact Fund holds 49%.
