TASHKENT, Uzbekistan – AN Podrobno.uz. An emergency shutdown of 1600 megawatts at a new thermal power plant in the Syrdarya region on the morning of September 25 caused power outages not only in certain areas of Uzbekistan but also in parts of Kazakhstan.
Uzbekistan's Ministry of Energy reported that the emergency shutdown occurred around 05:05 at the new thermal power plant of the EDF company. Commissioning and testing works are still ongoing at the station.
After the shutdown, emergency automation was triggered, temporarily cutting off electricity supply in some regions of the country. The disruptions mainly affected agricultural water pumps and household consumers.
Power supply to all disconnected consumers in Uzbekistan has already been restored. Backup capacities from energy storage systems and other power plants were used for this purpose.
The incident also affected Kazakhstan's power system. According to Kazakhstan's electricity generation company KEGOC, around 05:02, due to the disconnection of 1516 megawatts of generation in Uzbekistan's power system, a power flow from the Central Asian power system occurred, leading to the separation of the North–South transit.
In Kazakhstan, the volume of temporarily limited consumption amounted to 962 megawatts. Emergency automation operated normally.
By 05:43, parallel operation of the Southern zone of Kazakhstan's Unified Power System with the Central Asian power systems was restored, after which restrictions for consumers began to be lifted.
This is not the first case where an accident in the power system of one country in the region affects the operation of neighboring countries' power systems. On August 14, power outages occurred simultaneously in Uzbekistan, Kazakhstan, Kyrgyzstan, and Tajikistan. At that time, Uzbekistan's Ministry of Energy reported a disruption in the unified Central Asian power system due to an accident in a neighboring country's power system.
In Kazakhstan, the outages that day affected Almaty and the Almaty region, in Kyrgyzstan — Bishkek and the Issyk-Kul region, and in Tajikistan — a number of cities and districts.
