Background
CTE Antonio Maceo is a Major thermoelectric power station located near Santiago de Cuba, in eastern Cuba. On 15 April 2026 its Units 3 and 5 were simultaneously out of service, alongside outages at CTE Ernesto Guevara and CTE Felton, contributing to a national generation shortfall of 1,732 MW at the 20:30 peak.
The plant is part of Cuba's Soviet-era thermoelectric fleet and operates on heavy fuel oil. With an installed capacity of several hundred megawatts, it is one of the key generation assets for the eastern provinces. Maintenance backlogs, spare-parts shortages, and the fuel supply disruptions flowing from US Executive Order 14380 have made simultaneous multi-unit failures a recurring feature of 2025-2026.
Eastern Cuba, which CTE Antonio Maceo serves, has experienced some of the worst blackouts on the island, with outages reported at up to 16-18 hours per day in affected provinces. The plant's unreliability is a direct driver of that regional suffering. UNE's daily bulletins name specific unit failures, making CTE Antonio Maceo a visible indicator of the eastern grid's fragility.
