The article addresses the problems of growing electricity rates. Escalation of rates has an effect on the basic mining, transportation and production costs of energy-intensive sectors. In search of feasible solutions it is important to make a forecast of the interrelated development of the mining and power industries. For the transition to the new wave of innovation new tools and mechanisms of making the studied sectors competitive are required.
