The Terna group is the owner of the Italian national transmission grid (NTG) for high- and extra-high-voltage electricity and is the largest independent electricity transmission system operator (TSO) in Europe. We are operating in a scenario of energy transition, an unavoidable transformation process towards a sustainable and decarbonised energy production and consumption system where electricity generation is increasingly decentralised and based on using renewable energy sources. In this process we perform a fundamental role. From a simple operator, we are becoming the enablers and directors of the energy transition, guaranteeing an increasingly better integration of renewable sources and the gradual decarbonisation of the system.
