Central Asia power grid blackout triggers regional disputes

A large-scale power outage struck several regions across Kazakhstan, Kyrgyzstan, Uzbekistan, and Tajikistan on August 14, exposing the vulnerabilities of the interconnected Central Asian power grid. The blackout caused significant disruptions, including stalled metro systems and traffic lights in Almaty, and power failures in major population centers such as Bishkek and Dushanbe.

Disputes have emerged between regional authorities regarding the cause of the failure. Kazakhstan’s national grid operator, KEGOC, stated that the country’s North-East-South power line became overloaded after several generators at Kyrgyzstan’s Toktogul hydropower plant shut down. Kyrgyzstan’s ministry of energy initially attributed the blackout to a high-voltage line outage in Kazakhstan, though it later acknowledged a brief shutdown at Toktogul while maintaining that the Kyrgyz system should not be held responsible for the regional failure.

Uzbekistan and Tajikistan provided less specific accounts. Uzbekistan’s ministry of energy cited disruptions in a neighboring country’s grid, while Tajikistan reported that an exact cause had not yet been determined, specifically denying reports that the Nurek hydropower plant was the trigger.
