Electrons passing through international electricity networks follow the complicated physics of meshed alternating-current grids and do not respect price-zone borders.

This is illustrated by two obvious inefficiencies. First, cross-border transmission lines are rarely fully utilised despite persisting price differentials. Second, electricity very often flows from high- to low-price areas . Overall, the current system is light years away from the theoretically optimal use of European power plants and transmission lines that would characterise a fully functioning single energy market.

Yet the physical peculiarities of electricity make it a rather complex commodity, and frequent inefficiencies and position abuses by major market players have clearly established that completely free electricity markets are simply not possible. Electricity deregulation instead requires careful monitoring by ad hoc authorities and, rather paradoxically, a whole new regulatory framework.
