Cuba took a new step in its energy transition strategy with the full operation of the “Mayor General Ángel del Castillo Agramonte” Photovoltaic Solar Park, located in the municipality of Majagua. The facility contributes 5 megawatts to the National Electric System and represents an unprecedented innovation for the country.
The project stands out for incorporating, for the first time on the island, a storage system using batteries. This technology allows preserving part of the generated energy and using it during high demand periods or in case of power supply interruptions.
Additionally, the project is part of a cooperation program promoted together with China, which includes a total donation of 120 megawatts aimed at strengthening renewable energies in Cuban territory.
The main technological novelty of the Majagua solar park is its energy storage capacity. The system features state-of-the-art batteries capable of supporting an additional megawatt to stabilize the national electrical grid.
Thanks to this tool, the plant can regulate voltage and frequency variations, one of the main challenges of intermittent renewable energies like solar. In this way, a more constant and secure electricity injection is guaranteed.
Moreover, the system provides partial autonomy to the area in the face of general supply failures. In a context marked by power outages and structural difficulties, energy storage emerges as a strategic solution to reduce the vulnerability of the infrastructure.
On the other hand, Cuban specialists and Chinese technicians worked together on the construction and commissioning of the project. The cooperation allowed for the incorporation of technological knowledge that could be replicated in future energy developments on the island.
In recent years, Cuba has intensified its efforts to diversify its energy matrix and reduce dependence on imported fossil fuels. The expansion of solar parks has become one of the main bets to face the energy crisis.
Currently, the country is promoting various photovoltaic projects in provinces such as Ciego de Ávila, Holguín, Camagüey, and Las Tunas. These initiatives aim to take advantage of the island’s favorable climatic conditions, where solar radiation is abundant for much of the year.
Furthermore, the incorporation of renewable energies appears as a key tool to reduce generation costs and decrease pollutant emissions. Solar energy also helps alleviate the pressure on an aging electrical grid that faces recurring maintenance problems.
In parallel, the technological development linked to energy storage is gaining relevance. Batteries are beginning to be considered fundamental to ensure stability in electrical systems that increasingly depend on renewable sources.
The commissioning of the Majagua solar park generates benefits that go beyond electricity production. Firstly, it contributes to reducing fossil fuel consumption and the emissions of greenhouse gases associated with conventional generation.
Additionally, the use of solar energy decreases atmospheric pollution and improves the sustainability of the national energy system. The incorporation of batteries, in turn, promotes a more efficient management of the produced electricity.
On the other hand, the project strengthens the energy security of local communities. The possibility of having electrical backup during general outages is especially important in regions affected by infrastructure problems.
Thus, Cuba is slowly advancing towards a more resilient energy model, where clean energies begin to occupy a central place in the face of the economic, environmental, and social challenges of the present.
