Some power plants produce energy that cannot be sold. Their owners began to offer surplus electricity along with renting infrastructure, which interested cryptocurrency miners. According to a representative of the Eurosibenergo company, after some industries closed, considerable energy reserves were formed. To date, there are more than 70 sites with cheap energy and full infrastructure, where you can easily connect to electrical networks and substations. In order to attract investors with the goal of creating new industrial facilities, in July the site of Eurosibenergo began to work, which provides an overview of the proposed sites. Most requests, however, were from those involved in cryptocurrencies. They are mainly interested in capacities from 100 kW to 30 MW. The company is considering possible cooperation in this area, but has not yet concluded any agreements with miners. As you know, for cryptocurrency mining, the processing power of video cards or asics is needed, from which the so-called farm is created, which is a single powerful computing system. The main expense items in this case are the acquisition of video cards, payment for electricity and rental of premises. According to one of the owners of such a farm, his expenses for paying for electricity reach about a third of the total costs. However, for the Etherium cryptocurrency, electricity costs are less – about 10-15%. According to Internet Ombudsman Dmitry Marinichev, it makes sense to mine where there are more favorable natural conditions for this and electricity tariffs are lower. Such regions are, for example, Karelia and the Irkutsk region. Another opportunity to save money is to connect the farm directly to \This will help to avoid power losses, costs of energy transmission through electric networks and to connect to them. Marinichev himself is actively engaged in mining and spends about 3.5 million rubles to pay electricity for the farm for 1,500 ASICs. per month.
