Advantages of Market Coupling  Removes unnecessary risks of trading short-term transmission capacity and energy separately  Guarantees the optimal utilization of transmission capacity  Less prone to market abuse since capacity cannot be hoarded  All market participants benefit from cross-border capacity  Encourages liquid, robust spot markets

Optimal use of capacity (particularly when prices are close)
