This paper describes the design and operation of the electric power system for the Channel Tunnel. The system was basically developed by applying well-proven and reliable technology to meet the Tunnel's specific and unique requirements. Special consideration was given to: (1) safety aspects; (2) load balancing on the UK side; and (3) the logistic and environmental problems of the tunnels. The following sub-systems and aspects of the power system are considered in some detail: (1) the connections to the electricity grids on the UK and French sides; (2) the main high voltage intake sub-stations on the French and UK sides; (3) the tunnel auxiliary system, developed to meet the power system's special requirements; (4) the low-voltage distribution system; (5) the lighting system; (6) special considerations for tunnel equipment; (7) shafts and stand-by generation; and (8) the overhead catenary system. The two appendices are: (1) a glossary of electrical engineering terms and acronyms; and (2) a list of the main designers and suppliers. For the covering abstract see IRRD 877203.
