%A Claude Crampes %A Nils-Henrik M. von der Fehr %J Energy Journal %T Decentralised Cross-Border Interconnection %X Reaping the full benefits from cross-border interconnection typically requires reinforcement of national networks. When the relevant parts of the networks are complements, a lack of coordination between national transmission system operators typically results in investment below optimal levels in both interconnectors and national infrastructure. A subsidy to financially sustain interconnector building is not sufficient to restore optimality; indeed, even when possible, such subsidisation may have to be restrained so as not to encourage cross-border capacities that will not be fully utilised due to lack of investment in national systems. %N n°4 %K electrical grid %K interconnector %K externality %K regulation %K regional %K cooperation %P 147-169 %V vol.44 %C Cambridge %D 2023 %I Oelgeschlager, Gunn & Hain %R 10.5547/01956574.44.4.ccra %L publications46371
