Its objective is to optimise all the connections of
the electricity network, from the producers to the
consumers, in order to improve the energy efficiency
of the system.

Distribution Systems Operator Each day, Enedis develops, maintains and controls more than 1.3 million kilometers of power lines, including
702 000 km of LV (low-voltage) and 622 000 km of MV (medium-voltage) lines, serving 35 million customers.

This makes Enedis the European leading electricity distributor. The grid is owned
by the local authorities (municipalities or joint municipalities), which award concessions
to the company and entrust it with the grid’s management through delegation of
public service.
