CERN Accelerating science


The EL group is responsible for the CERN electrical distribution network from 400kV to 400/230V. Its main missions are to operate, maintain, extend and renovate the network, analyse and make projections for CERN electrical energy consumption and manage relations with the energy suppliers.

The group is also in charge of making modifications and extensions to the network as required by new projects, in terms of project studies, equipment procurement, installation, supervision and commissioning.

A section of the group is responsible for providing all cable installations for accelerators and experiments. This includes a great variety of HT and LV cables distributed over the entire CERN site and LHC ring. Fibre optics installation is also provided by this section.
