The biggest mining operations are Chinese and Russian farms getting their power through questionably legal arrangements, so those statistics probably don't exist and wouldn't have much relevance if they did.
You can't bribe your way into 30 megawatts of power.
The biggest mining operations have legal partnerships with local and national governments.[1] As well, Russia isn't a major place for bitcoin mining: instead, mining is mostly concentrated in Georgia (the country, not the state) and China.
