Background

CTE Ernesto Guevara is one of Cuba's largest thermoelectric power stations, located in Santa Cruz del Norte, Mayabeque province. On 15 April 2026 its Unit 1 was simultaneously out of service alongside units at CTE Antonio Maceo and CTE Felton, contributing to a national generation deficit of 1,732 MW against demand of 3,000 MW.

The plant runs on heavy fuel oil and has an installed capacity of approximately 500 MW across multiple generating units. Like most of Cuba's thermoelectric fleet, it was built with Soviet-era technology and has suffered from chronic underinvestment, spare-parts shortages, and delayed maintenance. The fuel supply disruptions caused by US Executive Order 14380 and the partial block on Venezuelan crude have compounded existing maintenance deficits, making multi-unit simultaneous failures increasingly common through 2025-2026.

CTE Ernesto Guevara's repeated outages are a reliable indicator of the severity of Cuba's energy crisis. When this station goes offline alongside the other large thermal plants, the national grid cannot meet peak evening demand, triggering the rolling blackouts that have become a daily feature of Cuban life. Its operational status is tracked in UNE's daily bulletins and closely watched by Cuban diaspora monitoring services.
