Abstract: This study examines the integration and price behavior of European Union electricity markets using a Vector Error Correction Model (VECM). Employing daily wholesale day-ahead electricity prices from 24 EU countries spanning October 2017 to September 2024, the research identifies seven regional clusters of markets based on similarities in price trends. The analysis reveals strong long-term equilibrium relationships and dynamic short-term adjustments, highlighting the interconnectedness of these markets. Central players, such as Germany in Block 1 and France in Block 2, emerge as pivotal in driving regional stability, while markets like Romania and Bulgaria (Block 3) demonstrate significant interconnections. Scandinavian and Baltic regions (Blocks 4 and 5) showcase unique balancing mechanisms influenced by shared infrastructure. Aggregated inter-block dynamics underscore the critical role of central hubs like Blocks 1 and 3 in bridging market disparities. Despite progress, regional heterogeneity persists, with slower adjustments observed in certain clusters. The findings emphasize the need for targeted policies to enhance cross-border electricity trading and infrastructure investments, ensuring equitable integration across all regions. By addressing these disparities, the EU can bolster market efficiency and resilience, contributing to its overarching energy strategy and transition to sustainable energy systems.
