Why are not all transmission capacities offered to the market?
Concerning the electricity market, some TSOs commonly use the alleged or real tightness of their internal generation and supply balance as an argument to limit cross-border transmission capacities. Also, internal network congestions are sometimes relieved by reducing the available transmission capacity on cross-border transmission lines. Such limitations eventually result in suboptimal generation and consumption patterns between EU member states and lead to higher costs of providing energy to European consumers.
