Yi-Kuang Chen, Hardi Koduvere, Philipp A. Gunkel, Jon Gustav Kirkerud, Klaus Skytte, Hans Ravn, Torjus F. Bolkesjø: The role of cross-border power transmission in a renewable-rich power system – A model analysis for Northwestern Europe, Journal of Environmental Management 261 (2020)

Abstract

This study quantifies the economic potential of cross-border transmission to a decarbonized future Northwestern European power system through the energy model Balmorel. A scenario with modelled optimal transmission capacity at lowest total system costs is compared to the scenario with given capacity level of existing and planned projects. Increased transmission investments decrease total system costs and regional price difference. It benefits particularly wind power deployment and thus, lowers CO2 emissions in the power and heat sector. The impacts are, nevertheless, distributed asymmetrically to northern and western stakeholders. Northern consumers receive higher power prices, but the revenues of wind and hydropower producers also increases. Meanwhile, western consumers receive lower power prices, but gas power producer revenues decrease.
