Assessing the quantile dependence and interconnectedness of electricity utilisation across Swedish industrial sectors

This study investigates electricity use interdependencies across Sweden's industrial sectors. Highlighting a knowledge gap in the literature on the complex relationship of sectoral power usage, and how it can aid in energy system integration. Using cross-quantilogram correlations, reveals nonlinear dependencies between different sectors, and adjusting for economic activity still show significant sector interconnections. The results are robust after adjusting for seasonal effects. These links inform on vulnerabilities and implications for energy system integration, sector coupling and "Power-to-X" technologies. The results emphasise the importance of understanding electricity use patterns for policy and industry collaborations concerning sustainable energy solutions, offering insights for stakeholders, and suggesting directions for future research to support policy and risk management. • Uses cross-quantilogram correlation method for detailed electricity use analysis. • Shows significant interdependencies in industrial sector electricity use. • Links food and beverage industry closely with other Swedish industrial sectors. • Shows the importance of electricity use behaviour in energy system integration.
