The shutdown of two hydropower generators at Kyrgyzstan's Toktogul Hydropower Plant caused a blackout in Kazakhstan and neighboring countries.
According to Renewables.az, Report reported on the matter, citing Kazakh media, that the system operator of Kazakhstan's Unified Electric Power System, KEGOC, made the announcement.

According to the statement, KEGOC fully restored power supply to consumers in the Karaganda, Ulytau and Abai regions at 14:47 local time, in the Almaty and Zhetisu regions at 16:26, and in the Zhambyl, Turkistan and Kyzylorda regions at 16:34.
