energivsene

Energivsene is a term used in Norwegian energy policy and planning to describe the network of large-scale energy transmission corridors that move energy across regions and national borders. The concept covers electricity transmission lines, gas pipelines, oil pipelines, and emerging vectors such as hydrogen and carbon dioxide transport routes. It is used to identify routes that are critical for maintaining supply and facilitating trade.

The energivsene are central to ensuring security of supply, smooth price signals, and the integration of renewable energy. By concentrating capacity along a limited number of corridors, the system can balance regional generation and demand and enable cross-border exchange during periods of shortage or surplus.

Planning and governance involve government energy ministries, national system operators, and cross-border coordination bodies. Analyses address capacity, resilience to weather and failure, land use and environmental impacts, rights of way, and the logistics of construction and maintenance.

Economic aspects: Investments in energivsene are typically multi-year and capital-intensive, often requiring public funding, tariffs, and public-private participation. Projects are prioritized based on reliability improvements, congestion reduction, system flexibility, and alignment with national and regional energy strategies.

Context and examples: In practice, energivsene align with known regional corridors within the Nordic-Baltic and European energy landscapes, including major interconnections between electricity grids and cross-border gas and oil transmission lines. The concept also guides planning for future hydrogen and CO2 transport networks.

Debates: Some stakeholders caution that a corridor-focused approach can underplay distributed generation and local networks, while proponents argue that well-planned corridors unlock large-scale decarbonization and market integration.
