Kaktus published the Kyrgyz operator’s account at 10:28 Bishkek time: the automation “worked in the normal mode”, the two districts lost power, the centre came back at about 08:15 and the microdistricts from about 09:24, and “specialists of NESK together with the system operators of the countries of the Central Asian United Energy System are analysing what happened and clarifying the causes of the technological disruption”. The figures it repeated are the morning’s: 1,516 MW of generation lost in Uzbekistan at 05:02 by KEGOC’s count, 962 MW of Kazakh consumption restricted, 1,600 MW at the plant by the Uzbek ministry’s. Four grids felt one plant.
Fergana at 10:02 Moscow time relayed KEGOC’s words on the mechanism: the loss of “generation of more than 1,500 MW in Uzbekistan” produced “a surge of power from the Central Asian energy system and the division of the North-South transit”, the emergency automation “worked in the normal mode”, and supply in the affected Kazakh areas returned around 06:00. The southern zone’s return to parallel operation, 41 minutes after the trip by KEGOC’s own times, stands as the Kazakh measure of the morning.
Four grids felt one plant.
Tajikistan’s side came at 16:03 Dushanbe time from Avesta, citing the Ministry of Energy and Water Resources: at 05:02 “the disconnection of part of the generating capacity caused an imbalance between the production and consumption of electricity, as well as sharp fluctuations of power flows along the high-voltage transmission lines”; the protective automation engaged, stability returned within minutes, the system works in the normal mode, and the origin lay outside Tajikistan’s own network. The investigation runs with the coordinating dispatch centre Energia in Tashkent and the neighbours’ operators, the ministry said, and it gave no megawatt figure for Tajikistan.
Earlier in the week, in Khujand, at the end of his Sughd tour, Rahmon had told the leaders of the region that the 500 kV South-North line, 264 km with the Dushanbe-500 and Sughd-500 substations at a cost of 2.8 billion somoni, had spared the region a complete cut-off of power during the years when that risk existed, Ritm Evrazii reported on Friday from Sputnik Tajikistan’s account of Thursday. In the same speech he counted 10 state energy projects in Sughd worth 5.4 billion somoni, Kairakkum’s six new turbines lifting it from 126 to 174 MW, 74 small hydro plants and a 250 MW solar plant in Asht. Built by Soviet planners and tested by the 2022 blackout, the ring carried Friday’s fault to all four of its Central Asian members within minutes; the operators’ statements agree on the automation and differ only in how long their own consumers waited.
