A total of 20 projects — 19 solar PV and one wind — were submitted under International Public Tender EDES-LPI-01-2024, aimed at awarding 600 MW of renewable energy generation with battery energy storage systems (BESS). The proposals total 1,655.92 MWp and 1,292.85 MWn, consolidating a level of competition that almost triples the capacity tendered.
The nominal capacity presented exceeds the contracted volume by more than 115%, pointing to a highly selective process in which the storage component will be decisive in both technical and economic evaluation.
The scheme’s design — which requires mandatory BESS integration — seeks to incorporate dispatchable renewable capacity, strengthening the stability of the Dominican electricity system and reducing exposure to generation variability.
The Northern Region leads the competition with 924.4 MWp and 729.9 MWn distributed across ten projects, equivalent to 56% of the total nominal capacity offered. The largest project submitted is Dicayagua Solar Park, with 180 MWp and 145 MWn.
In the same region are Parque Solar Dominicana Azul II (124.2 MWp / 96.8 MWn), Parque Fotovoltaico Taíno I (101 MWp / 84.7 MWn), Ardavín Solar (101.6 MWp / 83.4 MWn), Parque Solar Dominicana Azul (101.2 MWp / 82.9 MWn), Guayubín Solar II, Parque Fotovoltaico Botoncillo, Planta Solar Fotovoltaica Payita 2, Planta Solar Fotovoltaica Solsur and the only wind project on the list, Parque Eólico Esperanza (60 MWp / 48.3 MWn).
The Eastern Region totals 531.5 MWp and 396.3 MWn across seven initiatives, led by Instalación Fotovoltaica Mella Solar Project 1 (143.9 MWp / 99 MWn), while the Southern Region contributes 200 MWp and 166.6 MWn across three projects, completing the competitive map.
The difference between 1,655.92 MWp and 1,292.85 MWn reflects the typical oversizing strategy used in utility-scale solar PV projects. This approach optimises capacity factors and allows developers to use battery energy storage to manage surplus generation and smooth grid injection.
This process forms part of the country’s broader renewable energy roadmap. The Dominican Republic aims to reach nearly 2 GW of installed solar capacity by 2027, while by 2025 it already records 2,700 MW of renewable capacity in operation across 80 projects, including solar PV, wind power and other clean technologies. In this context, awarding the 600 MW with BESS would not only expand capacity but also represent a qualitative shift toward dispatchable renewables, reinforcing the transition from pure renewable expansion to grid-integrated renewable energy with storage.
What is the next step?
The process now moves into its decisive phase, beginning the qualitative evaluation of the submitted projects. During this stage, aspects related to technological configuration, BESS integration, grid connection feasibility and regulatory compliance will be assessed.
Once this stage is completed, the opening of economic bids on 7 April will mark the start of the financial evaluation and potential auction mechanism.
The economic assessment will be carried out throughout April, with the publication of the award expected between 27 April and 5 May, while contract signing is scheduled for 22 May.
