This paper describes the electrical power supplies which were installed for the construction of the French section of the Channel Tunnel. Almost all the power consumed by the Channel Tunnel project (98%) was electrical. For an installed capacity of 85,000 kW, consumption was that of a town of 25,000 inhabitants. This energy was provided by the Gravelines nuclear power plant, backed where necessary by the Paluel nuclear plant. On the site, electric power was distributed by three ring-main circuits. The main functions on the underground sites were clearly differentiated and the power circuits were doubled to ensure the dependability of the network. Finally, a stand-by power plant using diesel engines was provided to supply 8,500 kW when necessary. For the covering abstract see IRRD 866394.
