In a significant move to modernize the national power grid, the Unified Council of Electricity Companies (CUED) has unveiled a public tender for up to 600 megawatts (MW) of new renewable energy generation. Marking a national first, the bidding process mandates the inclusion of battery energy storage systems as an essential part of the proposed project.
The initiative aims to transform intermittent renewable sources into baseload power, thereby strengthening the electrical system’s stability and ensuring a reliable supply nationwide.
“I am seeing great interest [from bidders] which will definitely improve the situation for the distributors, and even more so with batteries,” stated CUED president Celso Marranzini, highlighting the transformative potential of the technology.
For years, numerous solar renewable energy parks have been installed. This is the first time that battery energy storage is part of a renewable energy park tender.
Battery energy storage represents one of the most significant global trends in the electricity sector. It addresses the inherent intermittency of solar and wind generation by storing energy produced during peak generation times for deployment when demand is high or weather conditions limit production.
Incorporating storage systems is expected to not only enhance system stability and reduce dependence on fossil fuels but also convert renewable energy into a continuous, manageable, and secure source. This, in turn, translates to greater operational efficiency and long-term energy sustainability for the country.
The Dominican Republic is following the lead of global energy transition pioneers, such as Spain, Chile, and the United States, which have already integrated these solutions into their energy tenders, setting a new global standard for clean and reliable power generation.
Key tender details
The solicitation specifically seeks to contract new wind and solar photovoltaic generation bundled with storage systems, with project capacities ranging from 20 MW to 300 MW, to reach the 600 MW total.
The conditions establish a supply period of 15 years. The contract is stipulated to start within 24 months following the contract signing. Likewise, distribution is allocated to the three government utilities — Edenorte (30%), Edesur (35%), and Edeeste (35%).
The launch event saw the participation of key energy figures, including Vice Minister of Energy and Mines, Alfonso Rodríguez, and the president of the Bidding Committee, Héctor Giuliani. The presence of 32 interested companies reportedly signals strong confidence in the regulatory stability and the nation’s potential to develop continuous, competitive, and clean energy.
