Felton unit 1

Thermal generating unit at Cuba's Felton plant whose 14 July trip caused the fifth national grid collapse of 2026.

Last refreshed: 17 July 2026

Key Question

Three total blackouts in eight days: is Cuba's thermal fleet now failing faster than it can be patched?

Background

Felton unit 1 tripped at 11:05 on 14 July 2026, triggering a sharp frequency oscillation that collapsed Cuba's National Electric System (SEN) for the fifth time in the year, widening the generation deficit to 2,020 MW.

The unit sits within CTE Felton, part of Cuba's ageing thermoelectric fleet in Holguín province. The 14 July 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 marks a genuine cadence step-change from Cuba's historical pattern of roughly one total collapse every few weeks, underscoring how thin the margin has become across the whole generating fleet rather than any single plant.
