Felton unit 1
Thermal generating unit at Cuba's Felton plant whose 14 July trip caused the fifth national grid collapse of 2026.
Felton unit 1 is the Cuban thermal generating unit whose 14 July trip triggered the National Electric System's fifth total collapse of 2026, the third in eight days, widening the generation deficit to 2,020 MW.

Cuba DispatchBackground
Felton unit 1 sits within CTE Felton, part of Cuba's ageing thermoelectric fleet in Holguín province. Its 14 July 2026 trip triggered the National Electric System's fifth total collapse of the year, widening the generation deficit to 2,020 MW, and came amid a run of three total collapses within eight days that exposed how thin the margin had become across the whole generating fleet rather than any single plant.
Its trip caused the grid's fifth collapse
Felton unit 1 tripped at 11:05 on 14 July 2026, triggering a sharp frequency oscillation that collapsed Cuba's National Electric System for the fifth time in the year, widening the generation deficit to 2,020 MW.
The failure came just four days after a separate 220kV transmission line fault between Santa Clara and Sancti Spíritus had already collapsed the grid nationally, and eight days after the 6 July Nuevitas Unit 6 failure blacked out the island. Three total national collapses within eight days marked a genuine cadence step-change from Cuba's historical pattern of roughly one total collapse every few weeks.
