European energy policy has shifted toward embracing cross-border electricity interconnections as a means to enhance energy security rather than pursuing complete national independence. This approach emerged from Russia’s invasion of Ukraine and its impact on energy markets, prompting a reassessment of how countries can protect themselves from supply disruptions.
The strategy centers on what analysts term strategic energy interdependence, which relies on multiple trusted partners, diverse electricity generation sources, redundant transmission routes, and sufficient backup capacity to absorb the loss of any single supplier or corridor without causing systemic instability. Current cross-border high-voltage direct current transmission project inventories reveal approximately 60 prospective international electrical links in Europe and surrounding regions, with projects like the Baltic-German PowerLink proceeding despite heightened infrastructure security concerns in the region.
Electrical interconnectors differ fundamentally from fuel pipelines in their operational characteristics. Unlike gas pipelines that depend on continuous fuel supplies and expose importers to commodity price fluctuations and supplier behavior, electrical interconnectors link power systems containing domestic generation, storage and multiple connections. Electricity typically flows bidirectionally across interconnectors, allowing countries to access hydroelectric, wind, solar, nuclear and other power sources from neighboring jurisdictions while retaining domestic resources. This creates a more reciprocal relationship compared to fuel dependencies.
Government bodies including ACER and British regulatory authorities have incorporated cross-border interconnection into broader frameworks encompassing storage, demand flexibility and renewable energy integration rather than treating them as isolated economic arbitrage opportunities. However, security benefits depend on maintaining portfolio diversity; a single large interconnector can itself become a concentration risk, particularly given the vulnerability of subsea cables and the potential for geopolitical disruption.
Analysts note that geopolitical tensions provided additional security justification for interconnector development that often already possessed economic and climate-related merit. The shift represents a move away from concentrated fuel dependence toward a more complex and reciprocal electricity portfolio architecture across borders.
