Its partners include the Cuban state-owned companies Unión Eléctrica (UNE) and CubaPetróleo (CUPET), and its foreign partner is Sherritt International. With an installed capacity of 480 MW across three plants—Energas Boca de Jaruco (Figure 1), Energas Puerto Escondido, […]

As part of the country’s strategic program to strengthen the stability of the national grid, Cuba has begun load testing of the first unit of a battery energy storage system (BESS) at the El Cotorro substation in Havana. This is the first of four systems with a total capacity of 200 MW. According to the […]

On March 4, the Cuban Electric Union (UNE) reported, through its official account on the social network X, that at 12:35 pm a partial power outage occurred affecting the national grid from the province of Camagüey to Pinar del Río province. Following the outage, all established protocols for system restoration were immediately activated, with the […]

The director of the National Load Dispatch Center of the Cuban Electric Union, Engineer Félix Estrada Rodríguez, reported that Cuba generated more than 800 MW of photovoltaic (PV) power during a midday period on Tuesday, Feb. 10, 2026. This achievement follows the installation of more than 1,000 MW of solar energy capacity throughout 2025, in […]

The Cabaiguán photovoltaic park, with a capacity of 21.87 MW, located in the central province of Sancti Spíritus, began operations after just over two months of installation. This is part of Cuba’s national plan that calls for the construction of 55 solar parks by 2025, each with a capacity of 21.8 MW, with a total […]

Cuban researchers have identified 21 areas in the country with favorable conditions for the installation of wind farms. These areas are mainly located on the north-central-eastern coast, from the provinces of Camagüey to Holguín, in the south of the eastern region and in the westernmost southern portion of Pinar del Río province. Alfredo Rodríguez, coordinator […]

Cuba suffered another massive blackout on Wednesday, Dec. 4—the latest in a series of devastating grid disruptions that have plagued the island in recent years. While authorities reported swift restoration—completed just after midnight on Dec. 5—the event has further underscored the growing strain on the island’s fragile energy system. Since 2020, Cuba has endured more […]

In the presence of Cuba’s Vice Prime Minister Ramiro Valdés and the Minister of Energy and Mines Vicente de la O Levy, the results of a study focused on the control and supervision of investments in photovoltaic parks and the maintenance of thermal power plants were analyzed in the Industry, Construction, and Energy Commission of […]

Cuba is in the throes of a severe energy crisis, driven by fuel supply disruptions and compounded by obstacles in securing vital technologies and supplies needed to modernize and operate its aging power plants. The situation, exacerbated by U.S. sanctions, has left the nation’s energy system teetering. At the same time, the island nation is […]

Since 2021, Cuba has been going through a complex situation in its national electrical system. Blackouts have been increasing, with higher incidence in recent months. Although projections predicted an

Distributed generation stands out in the Cuban power system, where there are hundreds of units dispersed throughout the country. In times of contingency, and as usually happens when a hurricane hits the country, distributed generation ensures the vitality of electrical service through interconnected systems in the form of “islands.” Of the slightly more than 6,000 […]

The state-owned Unión Eléctrica (UNE) is responsible for supplying electricity to the Cuban population and the national economy. This is a complex process in which more than 50,000 workers intervene, highlighted Jorge Armando Cepero Hernández, UNE’s general director during a recent press conference. The executive explained that electrical energy is produced with a generation fleet […]

As a part of a political movement to develop renewables and more efficiently use energy in Cuba, the state-owned company COPEXTEL will be responsible for commercializing photovoltaic (PV) systems for the Cuban

As part of Cuba’s National Economic and Social Development Plan for 2030, the country aspires to increase the share of renewable energy on its electric grid to 24%. To accomplish this objective, the

The first biomass-fired power plant in Cuba—located adjacent to Ciro Redondo sugar mill in the central province of Ciego de Ávila—recently synchronized its two boilers to the grid. The 60-MW plant is

Cuba is in the midst of a renewable revolution to transform, update, and adapt its fossil fuel–dependent power mix to its current energy needs. Because Cuba has a relatively high solar potential (~ 5 kWh/m2/day), and it is feasible to adapt solar photovoltaic (PV) technology to rural areas, islands, and isolated communities, commercial interest in […]
