Modeling European Electricity Market Integration during turbulent times

2025-06-29

AI Summary

This study investigates the resilience of European electricity markets during energy turbulence, focusing on how fossil fuel price shocks and renewable generation variability drive cross-border price differentials and volatility. We propose a Bayesian Reverse Unconstrained MIDAS model that integrates daily fuel prices, hourly wind and solar generation data, and panel electricity prices across countries, incorporating random effects to capture the dual “buffering–amplifying” role of market integration. Empirically, natural gas prices emerge as the dominant driver of cross-border price dispersion, whereas renewable generation consistently depresses national electricity prices. Moreover, energy diversification and coordinated gas supply strategies significantly enhance system stability. The proposed framework advances methodological tools for assessing heterogeneous, mixed-frequency market integration, offering a novel approach to modeling resilience in interconnected power systems under structural uncertainty and temporal misalignment.

Abstract

This paper introduces a novel Bayesian reverse unrestricted mixed-frequency model applied to a panel of nine European electricity markets. Our model analyzes the impact of daily fossil fuel prices and hourly renewable energy generation on hourly electricity prices, employing a hierarchical structure to capture cross-country interdependencies and idiosyncratic factors. The inclusion of random effects demonstrates that electricity market integration both mitigates and amplifies shocks. Our results highlight that while renewable energy sources consistently reduce electricity prices across all countries, gas prices remain a dominant driver of cross-country electricity price disparities and instability. This finding underscores the critical importance of energy diversification, above all on renewable energy sources, and coordinated fossil fuel supply strategies for bolstering European energy security.
