“Smart Regulation for Smart Grids” [PDF]

open access: yes, 2010
Florence School of Regulation Climate change and security of supply policies are driving us towards a decarbonization of the electricity system. It is in this context that smart grids are being discussed. Electricity grids, and hence their regulatory frameworks, have a key role to play in facilitating this transformation of the electricity system.
