What are smart grids?

According to the definition of the Smart Grids European Technology Platform, a smart grid concerns an electricity network that can intelligently integrate the behaviour and actions of all users connected to it - generators, consumers and those that do both - in order to ensure a sustainable and economically efficient energy system, with low losses and high levels of quality and security of supply.

Smart grids have a critical role in the transformation process of the functionalities of existing electricity transmission grids and distribution networks, facilitating the fulfilment of the 20-20-20 targets and ensuring a high level of security, quality and economic efficiency of electricity supply.
