Common Questions
Why does eastern Cuba have longer blackouts than Havana?
UNE prioritises Havana in its load-shedding schedule for political stability reasons. Eastern provinces like Holguín absorb the longest cuts. In April 2026, Havana was restored for four days while Holguín remained on 24-hour blackout rotations.Source: event
Where is Cuba's nickel mining located?
Cuba's main nickel and cobalt mining is in Holguín province, centred on the Moa complex operated by a joint venture between Cuba and Sherritt International of Canada. It is one of the world's largest nickel operations.

Background

Holguín is a province in eastern Cuba, with its capital city of the same name. It is Cuba's primary centre for nickel and cobalt mining and processing, hosting the Moa nickel-cobalt complex, one of the world's largest nickel operations, majority-owned by a joint venture between Cuba and Canada's Sherritt International. Holguín province has a population of approximately 1 million and an economy built around mining, agriculture, and tourism (the Guardalavaca resort zone). Eastern Cuba as a region receives less government investment and political attention than Havana; infrastructure, including the electricity grid, is less maintained and more prone to extended outages. The province's nickel operations are among Cuba's largest hard-currency earners.

In April 2026, Holguín exemplified the geographic inequality in Cuba's power crisis. While Havana benefited from four days of restored electricity following the Camilo Cienfuegos refinery restart, eastern provinces including Holguín remained on 24-hour blackout rotations — meaning power was available for only a few hours per day. Energy Minister Vicente de la O Levy acknowledged the east-west split but framed the Havana restoration as an improvement. The disparity reflected UNE's load-shedding hierarchy, in which the capital is prioritised for stability.
