Dominican Republic Launches 600 MW Renewable Energy Tender

Dominican Republic Launches 600 MW Renewable Energy Tender, Mandating Integrated Storage Systems for the First Time

 

 

 

 

The Unified Committee of Distribution Companies of the Dominican Republic recently held a pre-qualification round for a public tender covering 600 MW of renewable energy projects-marking the first time that energy storage has been mandated as an integral component of such projects. The tender aims to procure newly developed wind and photovoltaic (PV) projects integrated with energy storage systems, with individual project capacities ranging from 20 MW to 300 MW; a total of 32 companies participated in the event.

 

The power supply term for the projects is set at 15 years, and operations must commence within 24 months of contract signing. The generated electricity will be off-taken on a proportional basis by the distribution companies Edenorte, Edeeste, and Edesur, with allocation ratios of 30%, 35%, and 35%, respectively. Committee Chairman Celso Marranzini noted that the introduction of energy storage will enable renewable energy sources to fulfill a baseload power role, thereby enhancing system stability and the reliability of the national electricity supply, while simultaneously reducing reliance on fossil fuels.

 

According to data from BloombergNEF (BNEF), global battery energy storage costs reached a record low in 2025. The benchmark cost for four-hour duration battery storage systems saw a significant year-on-year decline, with prices falling below $100 per MWh in several markets. This cost reduction is attributed to lower battery pack prices, improvements in supply chains, and expanded manufacturing scale, which have continuously bolstered the cost-competitiveness of renewable energy projects paired with storage systems. In the same year, global installations of long-duration energy storage systems exceeded 15 GWh-a 49% increase year-on-year. As of October 2025, in markets outside of China and the United States, the capital cost for utility-scale battery storage systems with a duration of four hours or more stood at approximately $125 per kWh.
