What happened

Kyrgyzstan's Toktogul Hydropower Plant, the country's largest, tripped two 300 MW generating units on 14 August 2026, removing about 600 MW of generation from the shared Central Asian power system. The sudden loss triggered a cascading disturbance across the interconnected grid, causing outages and voltage disturbances reported in parts of Kazakhstan, Uzbekistan and Tajikistan; the Almaty metro in Kazakhstan halted service during the disruption. Grid operators restored power within hours through automatic protection systems and manual switching. The precise technical cause of the units' trip was not established in the cited reporting. This was reported as an equipment/operational failure rather than an attack or sabotage.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
