This work considers market based coordination of ancillary among neighbouring countries based on case study on the Baltic Sea Region (BSR). It assumes a common day-ahead market in-line with the EU Target Model but an independent balancing market. It models BSR as virtual node under various degrees of independence, from being part of a regionally coupled balancing market by a single TSO responsible for the region's system, to being an independent actor within the regional system. Under the latter scenario, each TSO is responsible for balancing its region without information on the grid of its neighbours. Consequently, they are not aware of their neighbours' balancing needs and how they may draw from the virtual node. The different approaches are evaluated in terms of operation costs / social welfare assuming different grid architectures (namely radial and meshed grid). Acknowledging that the independent approach is an unlikely step in the near future, we use it as a benchmark to evaluate policies and regulations proposed by the EU regarding the structure and operation of balancing markets across Europe.
