This paper deals with two phases of liberalization in the field of electricity. It does so by utilizing archival material and quantitative data, combining and contrasting it with work done by scholars of european integration. After an overview of interwar electricity discussions on international governance, it discusses the two post-world war ii phases. During the first a non-political organization informally arranged to lift interwar restrictions on international electricity flows, and turn it into a reliable operating system. The second phase brought a complete transformation of the existing regime, initiated by the european commission, turning electricity exchanges into trade flows.
