Iran previously imposed a temporary blanket ban on crypto mining during the summer, when power demand is at its highest.

Local energy authorities have decided to cease operations of authorised cryptocurrency mining centres as Iran’s energy usage rises over the winter.
Iran is shutting down crypto mining facilities again, according to Mostafa Rajabi Mashhadi, chairman of the board and managing director of Iran Grid Management Company (Tavanir), in order to cut liquid fuel use in power plants when temperatures drop.
The Islamic Republic of Iran Broadcasting stated on Saturday that Iranian officials took this move to curb energy use last month, according to Mashhadi.
“The Energy Ministry has been implementing measures since last month to reduce the use of liquid fuels in power plants, including cutting licensed crypto farms’ power supply, turning off lampposts in less risky areas and stringent supervision of consumption,” he said.
The president underlined the importance of energy conservation in the country, encouraging residents to minimise their power and gas consumption as much as possible. According to local sources, heating buildings accounts for 70% of all fuel utilised in Iran. Energy usage is predicted to be reduced by at least 40% as a result of the new energy-saving measures.
The Iranian government has been striving to curb illegal crypto miners while enforcing regulations on approved crypto mining operations. Local energy authorities reported in late November that since the industry restrictions were formed, they had confiscated a total of 222,000 mining machines used for illicit crypto mining.
Iran is one of the world’s largest cryptocurrency mining nations, accounting for 4.5 percent to 7% of the worldwide Bitcoin hash rate. The country previously imposed a temporary ban on crypto mining in the summer, citing historically high power use owing to scorching temperatures. After the Iranian electrical grid became more reliable, the embargo was lifted in September.
