Benefits of energy storage in the Dominican Republic
Written by Warren Peguero
From crisis to solution: energy innovation
The growing demand for energy in the Dominican Republic, coupled with the consequences of climate change, requires the country to strengthen its electricity grid. To ensure a continuous and reliable supply, it is essential to explore storage alternatives that support the electricity grid and ensure the quality of its essential services.
According to the Superintendency of Electricity (SIE), power outages continue to affect residential and industrial sectors, highlighting the limitations of the national grid’s infrastructure.
This situation is aggravated by the high dependence on imported fossil fuels, which increases costs and exposes the country to the vulnerability of the international market.
Against this backdrop, battery storage represents an innovative solution for modernizing the electricity grid, strengthening energy security, and improving national competitiveness.
Between 2023 and 2024, the country went from recognizing storage as a complementary technology to expressly requiring it in certain renewable projects and incorporating it into the planning and operation of the electricity system.
Battery energy storage is an innovative solution that —through chemical and power conversion processes— allows energy to be stored for later use. The continuous use of this storage makes it compatible with various renewable energy sources.
Tax incentives for energy projects
Law 57-07 on Incentives for the Development of Renewable Energy Sources establishes the framework of tax benefits to promote investment in solar, wind, and hydroelectric energy projects. Its tax provisions include tariff exemptions and tax breaks to boost the development of the energy sector.
In addition to these general incentives, there are specific provisions issued by the National Energy Commission (CNE). Through recent resolutions, variable renewable energy generation projects with an installed capacity of 20 MWac or more have been incorporated into the special regime. These projects must integrate battery storage systems with at least 50% storage capacity.
Until now, these benefits have mainly been applied to energy generation. However, the authorities may consider extending the incentives to include large-scale battery storage systems as a complement to renewable plants.
Although battery storage does not yet have a fully differentiated autonomous tax regime, its incorporation has been strengthened through technical resolutions and regulatory conditions that apply to certain generation projects.
Energy storage potential in the Dominican Republic
The National Energy Pact (PEN) recognizes the need to invest in storage infrastructure and new technologies, thus laying the groundwork for the Dominican Republic to move steadily toward a more sustainable energy matrix.
As the use of renewable energy increases, energy storage becomes increasingly important. In line with this, the Superintendency of Electricity (SIE), in coordination with the National Energy Commission (CNE), authorized a public tender for distribution companies (EDES).
This tender contemplates the incorporation of up to 600 MW of new renewable generation, in which the integration of storage systems was established as a mandatory requirement.
This measure ensures that new projects not only provide clean energy but also the technical capacity necessary to manage the variability of solar and wind sources, thus reinforcing the operational stability of the national electricity system.
Likewise, storage has begun to receive specific regulatory treatment within the Dominican electricity system, reinforcing its role as a technology increasingly linked to the expansion of renewable generation.
With the growth of solar projects in Baní and Monte Cristi, and the expansion of wind power in the north, energy storage is becoming a key tool for optimizing the energy generated during off-peak hours and using it at times of higher consumption.
As pointed out by the Ministry of Energy and Mines (MEM), this capacity would reduce power outages, stabilize grid frequency, and ensure a more reliable supply.
Benefits and future landscape
Battery energy storage offers key benefits for the Dominican electrical system. Among the most notable are reduced losses due to power outages, efficient use of renewable energy, and reduced dependence on fossil fuels.
In addition, these solutions stabilize the electrical grid by mitigating high demand and storing excess energy during off-peak hours.
Although large-scale implementation poses technical and economic challenges, the Dominican Republic has the opportunity to build a more stable, resilient, and sustainable energy grid through incentive policies and investment in technological innovation.
This transformation would also generate green jobs, boost foreign investment, and position the country as a regional leader in electrical modernization.
According to the Inter-American Development Bank (IDB), every dollar invested in energy innovation generates significant returns in competitiveness and employment. Therefore, investing in battery energy storage solutions is not a luxury, but an immediate necessity to ensure a reliable and sustainable electricity supply.
