On 25 January 2022 at 11:59 (Nur-Sultan time) a significant emergency imbalance in the Central Asian power system (Uzbekistan, Kyrgyzstan) lead to a power surge in North-East-South 500 kV power transmission line in Kazakhstan.

As a result, the North-East-South line was disconnected due to the fault, cutting power supply to a significant part of consumers in the southern Kazakhstan. The amount of load shedding is about 1,500 MW.

Currently, KEGOC, the System Operator, is taking measures to rectify the fault.
