Managing the electricity distribution network for the community of Geneva

SIG supplies 265,000 households with electricity across a network of 4,400 km. Managing this network is one of the fundamental tasks of the SIG Manager Distribution Network.

From the source of electricity production, to the zone where it is consumed, electricity has to travel through several generating plants. It Is transported across a transmission network made up of very high voltage power lines. The electricity is then carried across a distribution network via various substations that convert the voltage level from ‘Very High’ to ‘High’. Before being distributed to customers, the voltage is lowered several times again at other substations.
The Electricity Network Manager (Gestionnaire de Réseau de Distribution d’électricité (GRD)) manages the electricity distribution network. Its responsibilities include :
The GRD strives to supply the highest level of customer satisfaction by :
