Mapping distribution system operators for electricity and gas around the world

This paper presents a global mapping of energy distribution system operators (DSOs). The mapping illustrates the variation in power and gas distribution sector utilities across the world. We analyze information on 194 electricity and 67 gas utilities serving capital cities in 194 countries. The paper compares information on size, ownership, degree of integration, performance and quality of service. We find a large degree of variation across the world with significant differences between continents and economic groupings. Overall, the paper highlights the significant challenges facing many distribution utilities in promoting the energy transition, given their very different starting points.
