A tunnel builder is relying on Japanese pump technology for the construction of the underground power line between France and Spain - part of the European INELFE project.
The new line should help prevent massive blackouts, such as the one that occurred at the end of April.
Dewatering is crucial in the challenging environment, where the line runs entirely underground and three-quarters of the way under the sea.
BESSAC, the tunnelling contractor, is relying on Tsurumi drainage pumps, which have proven their worth in similar challenges.
BESSAC, a specialist in tunnelling and pipeline construction with 40 years' experience and a fleet of over 40 tunnel boring machines, relies mainly on the KTZ415 for dewatering in the three tunnels on the route, but also on other Tsurumi pump models
The INELFE (INterconnexion ÉLectrique France-Espagne) project of the two grid operators Red Eléctrica and RTE is a milestone in European energy infrastructure.
It will allow electricity to be transferred between France and Spain to improve security of supply from 2028.
This is particularly important for Spain, which has comparatively few connections to the European grid.
