Hesitation at increasing integration: The feasibility of Norway expanding cross-border renewable electricity interconnection to support European decarbonisation
本文提出一个技术-经济-政治可行性框架，评估挪威扩大跨境电力互联以支持欧洲脱碳的可行性，发现政治因素（如主权争议、电价影响）是最大障碍。
Norway is rich in renewable energy resources and exports a significant amount of electricity cross-border. By expanding its exports, Norway could play a crucial role in balancing the growing share of renewables in Europe's energy systems. This article therefore examines the feasibility of Norway expanding its electricity interconnection to support European decarbonisation efforts over the coming decades. To support the analysis, a techno-economic-political feasibility (TEPF) framework for assessing the feasibility of specified transition scenarios is proposed. The Norwegian context is explored through key developments such as the rejection of the 1400 MW NorthConnect cable in 2020 and the effects of Europe's energy crisis (2021−2023), alongside Russia's invasion of Ukraine (2022-), on the electricity market. While technological and economic factors are significant, such as grid reinforcement and investments in new generation capacities, political concerns pose the greatest limitations to increasing interconnection. These challenges revolve around debates over the ownership of key energy infrastructure, concerns over sovereignty and the influence of the European Union, uncertainty surrounding future energy demand, risks to energy security, the impact of market coupling on electricity prices, and the uneven distribution of revenues. Collectively, these concerns underpin Norway's hesitation to increase integration with other states, representing key barriers. • Proposes a techno-economic-political feasibility (TEPF) framework for assessing specified transition scenarios. • Includes thresholds for assessing the technological, economic, and political feasibility of transitions. • Provides an overview of Norwegian cross-border electricity interconnectors and their specifications. • Assesses the feasibility of Norway sending renewable electricity cross-border to support European decarbonisation. • Identifies the key barriers and hurdles to interconnection and explains how they could be overcome to enhance feasibility.
