South-East Europe Energy Highway – European Commission

To reinforce these efforts, the South-Eastern Europe electricity interconnection Energy Highway, aiming at improving price stability and energy security in southeastern Europe, including through storage, has been assigned a Pilot status under the CCT. The implementation of the Highway should smooth electricity price disparities across the region, where average price disparities between respective countries well trespass the 2 EUR/MWh threshold. 

In 2026, targeted discussions on increasing energy system flexibility will be initiated, preparing ground for the ensuing deployment of energy storage which will be supported through the CCT. Other potential bottlenecks in the implementation of the Energy Highway will also be explored, allowing space for additional priority actions to be established. To deliver results, the CCT will act via regional cooperation in the Central and South-Eastern Europe Energy Connectivity (CESEC) High-Level Group. Through the CESEC, the Commission will work together with Member States, industry, energy suppliers and other stakeholders across the value chain to deliver a more flexible energy system, enhance interconnection, promote the more efficient use of existing grids, and improve coordination. The CCT pilot complements other initiatives, notably the upcoming Tripartite agreement on energy storage.
