Holguín
Eastern Cuba province; nickel mining hub bearing the longest blackouts in the 2026 energy crisis
Holguín absorbed the blame on 14 July when a fault at its own Felton plant knocked out Cuba's national grid for the second time in a week, a reminder that the eastern province, already living under the deepest cuts, now supplies the failures as well as absorbing them.

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 has a population of approximately one million and an economy built around mining, agriculture and tourism (the Guardalavaca resort zone). Moa's nickel exports rank among the two or three largest sources of hard currency in the Cuban economy.
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. Sherritt International's Moa operations depend on stable electricity, so the province's blackout problem directly affects mining productivity, and OFAC's extension of its [Cuba-EO] sanctions tag to Moa Nickel SA has layered a separate sanctions-exposure track onto that operational risk for Sherritt.
The province usually absorbs the deepest cuts
In April 2026, Holguín exemplified the geographic inequality in Cuba's power crisis: while Havana enjoyed four blackout-free days after the Camilo Cienfuegos refinery restart, Holguín and other eastern provinces stayed on 24-hour rotation, power available only a few hours a day, reflecting UNE's load-shedding hierarchy that protects the capital first.
Holguín's own generating capacity turned from casualty into cause on 14 July: a fault in the province's Felton thermoelectric plant, north of the city, brought down national supply for a second time inside a week, adding 2,020 MW to the shortfall the operator was already fighting. Days later, the grid operator's mid-July forecast of the year's worst nationwide shortfall confirmed eastern provinces including Holguín were still first in line for cuts under the same load-shedding hierarchy.
