The machines, which produce cryptocurrencies that are banned in Iran, were mostly to blame for a 7 per cent increase in power consumption.
Iranian authorities have seized about 1,000 bitcoin mining machines in two abandoned factories, state television reported, after warnings that the activity had led to a spike in consumption of government-subsidised electricity.
“Two of these bitcoin farms have been identified, with a consumption of one megawatt,” Arash Navab, a power official in the central province of Yazd, told the television.
The machines, which produce cryptocurrencies that are banned in Iran, were mostly to blame for a 7 per cent increase in power consumption in the month to June 21, according to an Energy Ministry spokesman, quoted by the website of state-run Press TV.
In 2018, Iran’s central bank banned the country’s banks from dealing in cryptocurrencies, including bitcoin, over money-laundering concerns.
