Key project mastered together

Can two substations be installed and commissioned at the same time? Yes, we at SAG can.

The power network operator Réseau de Transport d‘Electricité (RTE) signed a contract with SAG Thepault for a specially challenging project. On the one hand, it included the expansion of an existing substation in Longefan and on the other hand, a new substation was to be installed in Le Bochet. Both stations had to be planned and installed in only five months. To implement this demanding project successfully despite its tight schedule and to prove ourselves for additional key projects, Thepault got support from the SAG colleagues in Germany.

The dual busbar system at the station in Longefan was expanded by a new transformer field with transformer station. In addition the 63 kV dual busbar system was expanded by three fields. To supply the silicate factory, a new substation with a 63 kV conductor field, a 42 kV conductor field, and a transformer station were constructed in Le Bouchet.

It was particular challenging for the German colleagues that all planning services
had to be provided in French. In addition, special procedures, which are implemented differently in France compared to Germany, had to be considered.
