North America’s Largest Bitcoin Mining Facility by Developed Capacity

Riot’s Rockdale Facility has a total power capacity of 750 MW, with 450 MW currently developed. This facility is believed to be the largest single facility, as measured by developed capacity, in North America for Bitcoin mining. The Rockdale Facility is currently undergoing a substantial expansion project that is nearly doubling the site’s Bitcoin mining capacity to 700 MW. This expansion includes four new buildings, totaling approximately 240,000 sq ft. and adding 400 MW of capacity. Once this expansion is complete, it is expected that Riot’s Rockdale Facility will be the largest Bitcoin mining facility in the world, as measured by developed capacity.

In addition to Riot’s self-mining operations, Riot currently hosts Bitcoin mining operations for two institutional clients who, utilize up to 200 MW of aggregate power capacity. In addition to hosting revenue, Riot generates engineering and construction services revenue from hosting clients on site, including revenue derived from the fabrication and deployment of immersion-cooling technology for Bitcoin mining.
