Analysis and Modelling of Cost-Sharing for Remedial Actions in Internationally Coordinated Congestion Management

Rising congestion in the European transmission system has increased the volume and cost of congestion management (CM). International coordination of remedial actions (RAs) can reduce overall costs by enabling cross-border flexibility, but it also complicates cost sharing (CS), as the location of costs no longer coincides with the origin of congestion. European regulation therefore requires cost allocation mechanisms that reflect causal responsibility.
