In Russia, huge amounts of electricity are sold to China at very cheap prices, and a Russian company is building a data center in Ethiopia, where the civil war recently ended but the situation there is very difficult. In this data center, you can install 120,000 ASICs of 3.3 Kilowatt each, which will be a big investment.
According to the article, the mining center will be located in the Capital City Addis Ababa, which I believe did not experience the civil war. Besides, Russia is also engaged in some sort of war that we don't know when it will end.
If electricity is too cheap in Russia, what could be another reason that Russian companies building mining centers outside? Building a company outside of your own country is kind of expensive. As you mentioned, the civil war ended recently and the situation is difficult as well.
Ethiopia probably have cheap electricity as well because it's situated in the
Nile basin. I did some research, and they have quite a number of hydroelectric power plants -
https://www.gem.wiki/Category:Hydroelectric_power_plants_in_Ethiopiain the article, they say
“100% of the data center’s electricity comes from renewable energy sources, specifically from the Grand Ethiopian Renaissance Dam, the largest hydropower project in Africa, with a capacity of 5.15 GW,”
Another factor could be the political climate in Russia and maybe the uncertainty towards crypto adoption. Russia is the kind of country that wakes up and bans whatever they want.
