Central Asia hit by large-scale power blackout

Millions of people were left without power after a huge blackout hit three Central Asian countries Tuesday following an unspecified accident, officials in the ex-Soviet region said.

The capitals of Kyrgyzstan and Uzbekistan as well as Kazakhstan's economic hub Almaty suffered power cuts at around lunchtime local time, with media and officials reporting that the blackouts had extended far into the provinces of the three countries.

Uzbekistan's energy ministry said in a statement on its official Telegram channel that the power outage had been triggered by an accident in Kazakhstsan's power grid.

"As a result of a major accident in the power grids of the Republic of Kazakhstan, there was a power outage in the (southern Kazakh) cities of Almaty, Shymkent, Taras, Turkestan (regions) and adjacent areas," the statement said.

"The Uzbek power grid, which is connected to the Unified Power Grid, was damaged as a result of an accident that led to sudden changes in voltage and frequency on 530 lines from Kazakhstan," it added.

A spokesman for Kyrgyzstan's energy ministry told AFP by telephone that power had failed "due to an accident in the regional energy grid".

Central Asian countries have seen their grids burdened by a summer drought that affected hydropower capacity in Kyrgyzstan and by a boom in cryptocurrency mining in the region, especially in Kazakhstan.

The growth of cryptocurrency mining in Kazakhstan was linked in part to a de facto ban on the practise in next-door China, and a spike in prices for volatile cryptocurrencies such as bitcoin in the second half of last year.

Southern Kazakhstan, which traditionally endures energy deficits and relies on supplies from the electricity-rich north of the country, was especially affected by the influx.

Kazakhstan's national electricity provider KEGOS said that "due to a significant emergency imbalance created by the energy system of Central Asia (Uzbekistan, Kyrgyzstan), there was a surge in power for the transit of electricity" between grids in Kazakhstan.

Russian news agency RIA Novosti reported that the airport in Almaty, where the power cut did not affect the whole city, was continuing to work normally, but that Tashkent's airport had stopped receiving flights due to the power outage.

Tashkent's metro, the largest in the region, had also ceased working, an AFP correspondent noted, adding that tap water was barely running.

Bishkek's airport was working at reduced capacity, local website 24.kg reported, citing the airport's management.
