I was confused with this news. It says the country will cut power to all licensed miners but then it also continues saying that this action is to be implemented to cut off power to illegal mining operations. I don't know if this article is only badly written or the official directive of the country is also confusing.
It is badly merging two different statements.
1. Iran is always fighting illegal miners who are mostly stealing electricity to mine cryptocurrencies (with basically free electricity). The operation against them is always intensified during summer since the electricity consumption naturally grows a lot.
2. Power is supposedly going to be cut for undefined period to legit miners with licence like some other industries to pre-plan for the natural increase in electricity consumption.
"Due to international sanctions, Iran lacks the investment needed in power generation capacity and natural gas production to keep up with consumption.
That is nonsense. Iran has the biggest gas reserves in the world and is currently extracting the highest amount per day, that is more than we can use and most of it is being exported.
The problem is that manufacturing of new power plants hasn't been as fast as speed of consumption increase. For example the construction of the 2 new nuclear power plants would take another year to finish which is normal but still it can't keep up with the consumption. There are 2 more under construction that would take longer than that.
For political reasons, the Iranian government spends over $60 billion annually in indirect subsidies to depreciate electricity prices"
That is partially nonsense. Energy in Iran has always been cheap because we have the biggest reserves in the world and extraction of it is easy and the quality is high (eg. the oil is light and doesn't need much effort to extract). Also due to exchange rate and the sudden drop of it 4-5 years ago the cost becomes a lot smaller when converted to dollars.
