Cuba suffers fourth blackout in six months and accelerates investment in solar energy

The Cuban population faced yet another widespread blackout this weekend, the fourth in less than six months. 

The failure occurred at a substation in Diezmero, on the outskirts of Havana, on Friday night (14), the which led to the total shutdown of the national electrical system.

The supply of electricity began to be restored in the country only on Saturday (15), slowly and gradually. 

The energy crisis in Cuba has worsened in recent years due to an obsolete electrical system, made up of eight old and worn-out thermoelectric plants, in addition to the constant shortage of imported fuel. 

Currently, more than 95% of Cuba's energy comes from fossil fuels, while only 5% is generated by renewable sources. 

As a result, blackouts have become increasingly frequent, affecting people's daily lives and deepening the Caribbean island's economic challenges. 

Given this scenario, the Cuban government is betting on the expansion of solar energy to reduce its dependence on fossil fuels and alleviate problems in the supply of electricity.

In February, President Miguel Díaz-Canel inaugurated the first of 92 photovoltaic parks that are part of a China-backed plan to minimize blackouts in the country.

According to the government, 55 new photovoltaic plants will come into operation in 2025, while the other 37 projects foreseen in the plan will be implemented between 2026 and 2028. 

The goal is that, by 2030, solar energy will represent 37% of the Cuban electricity matrix, with a total generation capacity of over 2.000 MW.

The initiative aims to ensure greater stability to the national electrical system, but the success of the plan will depend on overcoming financial and logistical challenges for the implementation of the plants. 

Meanwhile, Cubans continue to face recurring blackouts, reinforcing the urgency of finding solutions to the country's energy supply.
