Description

This presentation provides an updated overview of the FCC electrical grid and infrastructure as established for the Feasibility Study Report, with a particular focus on developments since the FCC Week 2024.

The feasibility study of the HV line running through the tunnel has been completed, delivering key outcomes, notably regarding integration requirements. Electrical equipment needs have been estimated across the various facilities, enabling the initial detailing of integration requirements.

The secured electrical network concept has been further developed and discussed with the safety team, leading to a preliminary agreement, contingent upon specific conditions being fulfilled.

The electrical grid is now defined from the connections to external grids, through the HV transmission network to the MV distribution network, reflecting the latest users’ requirements and study outcomes. Distribution networks concepts are well defined with several optimization approaches identified.

Finally, the next steps required to reach the necessary level of detail for the pre-TDR phase are outlined.
