This is something we have always had a bit of an edge up on. My partner and I have run a boutique commercial real estate company for the last ten years, so we have always had a bead on the industrial market across the nation. With crypto mining gaining in popularity, we started to pay a lot more attention to the industrial properties that came across our desk in markets with abundant power. I can't suggest a particular site for finding these locations, as the majority of the properties we receive come to us through our own website via SEO. Running power to a site, necessary upgrades, or line extensions have generally cost us anywhere from $40,000- $70,000. Calling the local power provider is relatively straightforward, but with the increase in miners, it is becoming more difficult to get on the phone with decision makers. The larger the ask (5MW+), the more likely they will take you seriously. Other factors to consider are site security, insulation, AIR FLOW, internet connectivity, and management.
