EDSOEDSO for Smart Grids (EDSO) is an European association, formed in 2010 and representing leading European Distribution System Operators (DSOs) for Electricity, cooperating to bring smart grids from vision to reality and focused on guiding European and member states’ RD&D, policy and regulation to support this development. EDSO is the key-interface between Europe’s DSOs and the European institutions, promoting the development and large-scale testing of smart grid models and technologies in real-life situations, new market designs and regulation.
