Cuba's Power Grid Faces Systemic Breakdown

Cuba endured its eighth nationwide blackout since late 2024 on July 6, 2026. With eleven thermoelectric plants offline and a 2,050 MW generation shortfall, cascading failures are now the pattern, not exceptions. Russian fuel shipments—one tanker every six months since January—cannot sustain demand. Another thermal unit failure could trigger total collapse; the grid lacks reliable black-start capacity to recover from complete disconnection.
