Quays of Bordeaux : a greener powering of the boats

Bordeaux Métropole and Enedis realize with the help of Europe, the powering of the Lafayette and Jefferson pontoons for more than 2,6 M€ investment, to reduce C0² emissions and atmospheric pollutants from the docked ships.

As one of the UNESCO World Heritage Site, the connection of the pontoon to the Chartrons quay is a twofold challenge, both in terms of environment and flooding risks. This electrical connection project of the pleasure and river boats will reduce noise pollution and eliminate the need of diesel generators to supply electricity on board.

Enedis is piloting the largest electrical grid on Europe at the service of the society and territories. Since 1955, we have been partners in continuous improvement, innovation and maintaining network quality.

As concessionaire of the electrical grid, Bordeaux Métropole is committed with the energy transition and climate protection. The aim of this project is to offer an alternative to the use of diesel generators on docked ships, to improve air quality and reduce noise pollution.

Ormazabal solution

Working with Bordeaux Métropole, Enedis and the UNESCO, we looked for the most suited solution that would not alter the site, while meeting the various requirements: the choice fell on a concrete monobloc underground substation of type pfs-62 including two rooms. One part is used by Enedis and stores HV/LV equipment, and the second one is made available to Bordeaux.

Facing the potential overflow of the Garonne River, the choice of installing the substation in a watertight metallic formwork with a pump-out water evacuation system, minimizes the risk of water penetrating the substation and complies with the Plans for Flood Risk Prevention (PFRP).
