Determinants of change in Electricity Distribution System Operators: A review and survey

The role of electricity distribution system operators (DSOs) in the European Union (EU) is changing. This paper aims at identifying the determinant factors for change at the DSO level. This is achieved through a two-staged research approach. Firstly, an exploratory analysis of the existing literature is conducted to identify candidate determinants. Secondly, the candidate determinants are evaluated, in terms of their adequacy and impact on DSOs, through a stakeholder consultation aggregating the perspectives of 30 experts. Through this study 22 determinant factors, within the institutional, technological and organisational dimensions were identified and validated as causes of organisational change for DSOs. Policy makers can build on these findings for the development of policies that take the organisational dynamics into account which can result in a more robust understanding of the necessary policy framework to facilitate the ongoing transition at the DSO level.
