The majority of the electric current in the Grand Duchy of Luxembourg comes from Germany via two double high-voltage 220,000 volt (220 kV) lines that are connected to the German network. Interconnection with Belgium has become operational with the commissioning of a phase shifting transformer (PST) at the Schifflange Centre in October 2017, and around 15% of the energy is produced locally (biogas, cogeneration, wind turbines, hydroelectricity and photovoltaics). The electricity is transmitted to the six transformer stations (Flebour, Roost, Itzig/Blooren, Heisdorf, Bertange and Schifflange) where the voltage is reduced from 220 to 65 kV and is distributed to industries and large municipal distribution networks. The voltage is then reduced from 65 kV to 20 kV in more than 60 transformer stations in the whole country. The electric energy obtained is distributed to SMEs, towns and villages where the transformers reduce the current voltage to 0.4 kV before distributing it to the final consumer. A control centre, known as Electricity Dispatching, controls and manages these high and medium-voltage networks.
