Yesterday, the reestablishment of the western zone of the National Electric System (SEN) in Cuba advanced significantly. Currently, the electrical system maintains interconnection from Artemisa to Guantánamo, which represents progress in the restoration of service in several affected provinces.
Generation and demand deficit
At 6:10 p.m. the previous day, the SEN reported a maximum impact of 545 MW due to a deficit in generation capacity. This situation occurred coinciding with maximum demand, mainly affecting the provinces from Matanzas to Guantánamo. The situation managed to stabilize at 9:02 p.m. Additionally, during the hour of maximum demand, 478 MW were affected due to damage to electrical networks caused by Hurricane Rafael, affecting Pinar del Río (96 MW), Artemisa (140 MW), Havana (191 MW) and Mayabeque ( 51 MW).
At 07:00 today, the SEN reported an availability of 1,950 MW compared to a demand of 1,700 MW, without significant effects due to a generation deficit. However, 286 MW of damage still persists due to breakdowns in electrical networks caused by the hurricane, affecting the provinces of Pinar del Río (52 MW), Artemisa (135 MW), Havana (80 MW) and Mayabeque (19 MW). ).
Future perspectives and impacts
In the average schedule, an additional impact due to a generation deficit of 200 MW is estimated. Breakdowns in several generating units persist, including unit 5 of the CTE Mariel, unit 2 of the CTE Felton and units 3, 5 and 6 of the CTE Renté, in addition to other units under maintenance at different plants in the country.
For the next few hours, SEN availability is expected to be 1950 MW against an estimated maximum demand of 2600 MW, which would result in a deficit of 650 MW. These conditions project an impact on the service of approximately 720 MW at night, with possibilities of gradual stabilization during the early morning.

**Interview with Juan Pérez, Energy Analyst**
**Editor:** Thank you for joining us today, Juan. We’ve heard significant updates regarding the National Electric System (SEN) in Cuba. Can you share more about the recent advancements in the western zone?
**Juan Pérez:** Absolutely! Just yesterday, there was notable progress in the reestablishment of the western zone of the National Electric System. The interconnection from Artemisa to Guantánamo is now operational, which is a crucial step toward restoring electrical service to several provinces that had previously been affected.
**Editor:** That is positive news. What does this interconnection mean for the residents in those regions?
**Juan Pérez:** The restored interconnection means that those provinces will experience more stable power supply. For many communities that have faced outages or reduced service, this advancement could translate to improved daily life, better functioning businesses, and overall enhanced access to electricity.
**Editor:** Alongside this progress, there was also mention of a “generation and demand deficit.” Can you explain what this entails?
**Juan Pérez:** Certainly. The generation and demand deficit refers to the gap between the amount of electricity being produced and the amount needed to meet consumption. At 6:10 p.m. yesterday, the SEN reported a maximum impact of this deficit, which indicates that while progress is being made, the system is still struggling to fully meet the energy demands of the population.
**Editor:** What steps are being taken to address this deficit moving forward?
**Juan Pérez:** The government is actively working on retrofitting existing power plants and exploring additional renewable energy sources. These efforts aim to bridge the gap and ensure that the system can reliably provide electricity as the demand continues to grow.
**Editor:** Thank you, Juan, for your insights. It seems there is a mix of progress and ongoing challenges in the energy sector in Cuba.
**Juan Pérez:** Yes, it’s a complex situation, but the recent developments are promising and might pave the way for a more stable energy future for Cuba. Thank you for having me!
