Camagüey

Camagüey is Cuba's largest province by surface area, located in the central-eastern part of the island. Its capital, also called Camagüey, is Cuba's third-largest city and a UNESCO World Heritage Site for its colonial-era street plan. The province's economy combines cattle ranching and agriculture with the Nuevitas thermoelectric plant on the northern coast, which feeds the eastern segment of Cuba's National Grid.

At 06:09 on 14 May 2026, Camagüey lay inside the section of the Sistema Eléctrico Nacional that partially disconnected from Ciego de Ávila through Guantánamo; Unión Eléctrica Nacional reconnected the province at 09:19, the second link in a sequence that continued through Las Tunas and Holguín. Bloomberg satellite analysis later showed Camagüey's nighttime-light recovery sitting between the reconnected central provinces and the eastern microsystem zone.

Camagüey returned to the centre of Cuba's energy crisis on 6 July 2026, when Unit 6 failed at the Nuevitas thermoelectric plant on the province's northern coast, triggering a cascading disconnection that blacked out the entire National Grid. It was Cuba's fourth total SEN collapse of the year and its seventh nationwide blackout in eighteen months, with a deficit of up to 2,230 MW. The three-day staged restoration that followed Left parts of neighbouring Matanzas dark for up to 87 hours, underlining how a single failed unit inside Camagüey can still cripple the whole island.
