SIEMENS – Combined Cycle Power Plant

Siemens built a combined-cycle gas power plant in Landivisiau (Finistère, France) on behalf of the Compagnie Électrique de Bretagne, a company owned 50 % by Direct Énergie (later Total Energies) and 50 % by Siemens during the development phase.

With a capacity of 446 MW and an investment of €450 million, the plant ensures that the Brittany region avoids any blackouts during peak winter consumption periods. The facility covers 7.5 hectares and includes multiple buildings.

LSC360 was responsible for the formwork and reinforcement plans, as well as the preparation of seismic calculation reports for all reinforced concrete foundations on the site.
