What is a DSO?

Published by European Distribution System Operators (E.DSO), Why smart grids?Website: edsoforsmartgrids.eu Distribution system operators (DSOs) are the operating managers (and sometimes owners) of energy distribution networks, operating at low, medium and, in some member states, high voltage levels (LV, MV). Transmission grids transport large quantities of high (and extreme high) voltage (HV, EHV) electricity across vastContinue reading “What is a DSO?”
