The voltage of electricity is raised and lowered through the use of transformers, electrical devices which allow energy to be connected and transferred between different voltage grids. Because of the transformers, the energy produced at medium voltage in the power plants is first transformed into high- and extra-high voltage to then be brought back to a lower voltage level near the end users. This ensures that the energy is transported efficiently, given that, for the same amount of power transmitted, the greater the voltage, the lower the grid losses along the power lines. In Italy, Terna has 781 transformers on its high-voltage electricity grid.

Green transformers are the new frontier of sustainability and a feather in the cap of all-Italian technology. Recently active at the Calenzano electrical substation in the province of Florence, the new green ATR includes an innovative feature which combines technology and environmental protection to ensure the security of the electrical infrastructure. In fact, the plant-based oil used in the plant reduces the risk of fire and any environmental effects due to exceptional events, an additional element in the system's energy transition process.
