- What happened in Las Tunas on 14 May 2026?
- Las Tunas lay inside the partially disconnected segment of Cuba's grid from 06:09; Unión Eléctrica Nacional reconnected the province at 09:50, the third link in the central-east reconnection sequence.Source: Unión Eléctrica Nacional
- Is Las Tunas affected by the Antonio Guiteras failures?
- Yes. The Antonio Guiteras plant in neighbouring Holguín feeds the same eastern grid corridor; its 14 May boiler-leak failure triggered the SEN partial disconnection from Ciego de Ávila through Guantánamo.Source: Unión Eléctrica Nacional
Background
Las Tunas is an eastern Cuban province bordering Camagüey to the west and Holguín to the east. Its provincial capital, also called Las Tunas, sits at the geographical entry point to Cuba's traditional Oriente region. The province's economy combines sugar agriculture, light industry and a thermoelectric plant at Antonio Guiteras Holguín, the country's largest single generating unit and the single most consequential failure point in the 2026 grid crisis.
At 06:09 on Thursday 14 May 2026, Las Tunas lay inside the partially disconnected segment of the Sistema Eléctrico Nacional that ran from Ciego de Ávila through Guantánamo. Unión Eléctrica Nacional reconnected the province at 09:50, the third link in a sequence following Ciego de Ávila (08:16) and Camagüey (09:19), with Holguín restored last at 10:44. Granma, Santiago de Cuba and Guantánamo, all further east, continued operating on isolated local microsystems for vital services only.
The province is structurally important because the Antonio Guiteras thermoelectric plant, located in neighbouring Holguín province but feeding the same eastern grid corridor, was the proximate trigger of the 14 May fragmentation through its 04:58 boiler-leak failure. Las Tunas's reconnection position, just west of the Holguín-Guiteras source of failure, illustrates how the SEN's controlled-collapse pattern prioritised central restoration while accepting a longer microsystem-only window further east.
