According to the Ministry of Energy of Uzbekistan, an emergency situation that occurred on June 19, 2025 at the Ekibastuz power node in Kazakhstan seriously affected the general power grid of Central Asia. Due to adverse weather conditions, the 500 kV transmission network failed, which resulted in a decrease in the frequency of the entire power system. This, in turn, led to power outages in Uzbekistan.
The incident that occurred in the Ekibastuz region of Kazakhstan may be associated with the failure of some of the links due to severe storms, rain or cold weather throughout the region, overloading of transformers, or the spontaneous activation of automatic safety systems. In such conditions, the voltage transmitted through the uninterruptible power transmission network changes, the frequency decreases, and this situation destabilizes the entire system.
The Central Asian Unified Energy System supplies Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan and Turkmenistan together. Therefore, a malfunction at one connection point directly affects the entire system. After a frequency drop was detected in Uzbekistan, the Ministry of Energy took emergency measures and introduced mandatory electricity restrictions in some regions.
According to the Ministry of Energy of Uzbekistan, work was carried out at the scene in cooperation with specialists and emergency crews called in for assistance. At 19:30, the malfunction on the 500 kV transmission line was eliminated and the power supply was restored.
There were no long-term and large-scale outages in the country. However, short-term interruptions in power supply were observed in some cities and industrial zones. These restrictions were applied operationally to eliminate the accident and restore system stability.
According to energy experts, this disconnected state of the Central Asian power system requires constant revision. In particular, it is necessary to modernize transformers, lines, and fan-stabilized systems with weatherproof fans and reinforced automatic components. It is also important to increase the safety of the systems through online monitoring and emergency backup systems.
In conclusion, the emergency outage at the Ekibastuz substation in Kazakhstan also affected Uzbekistan, leaving fans without electricity. However, thanks to the prompt elimination of the accident and restoration of the system, the problem was quickly resolved. This situation once again demonstrated the importance of the central power system and the need to maintain stability. Read 'Zamin' on Telegram!
