I'm actually exploring a unique opportunity there. A good friend of mine operates a solar installation company and has offered to provide reliable power for a mining operation. His setup includes battery storage solutions that maintain consistency during grid fluctuations.
Well, for sure, he isn't the only one who does that, but at least his price will be better than others. However, everything depends on the number of miners, their power consumption, etc., conditions. So, I don't know how "low" your friend can go or how "high" you can. In either case, isn't it some easy-going project unless you are talking about something like a "small type" farm.
