Major challenges in the CEE region  FBA implementation Unlikely increase of cross-border capacities Shift from an option to use the capacity to an obligation of traders Limited transparency Potentially discriminating  Increasing difference between scheduled and real flows Influenced by expansion of wind generation in North Germany Existence of regional bottlenecks (often inside the countries)  Interconnection improvements without stronger EU support to overcome environmental and ownership barriers  More intensive market coordination: Regional balancing market with single price structure Harmonised regional settlement market Regional market with ancillary services
