Why is Cuba focusing on solar energy and battery storage? Cuba is investing in solar energy and battery storage to address its severe energy crisis, reduce dependency on fossil fuels, and improve the reliability and stability of its power supply. These Battery Energy Storage Systems (BESS), also referred to as "concentrator units," are being placed at Cueto 220, Bayamo. The national plan prioritizes solar, wind, hydroelectric, and biomass energy to reduce its dependence on imported fossil fuels and stabilize the energy system. The energy stabilization program also includes the repair of the country's thermoelectric plants, which have been the backbone of the. These photovoltaic parks are part of a plan presented by the Cuban Ministry of Energy and Mines (Minem) in March 2024, which proposes the installation of a total of 92 photovoltaic parks by 2028, with a total installed capacity of 2,000 MW (Figure 1). Cuba plans to build a total of 92. HAVANA TIMES – The same Chinese company that designed the Soyea decoder box models for Cuba's failed digital television project is now one of the suppliers of panels used in the photovoltaic development program with which the Government intends to resolve the island's electricity crisis. This article explores active initiatives, their applications, and how companies like EK SOLAR contribute to Cuba's energy transition.
