Power supply points

Ships under 120 metres in length - such as the dredger Cap d’Aunis, sand carriers, and ships undergoing technical stopovers at the Shipbuilding and Repair Centre - can now operate at berth without needing to use their thermal generators.

The available power supply ensures optimum working conditions during ship maintenance, eliminating engine noise. In addition to reducing noise pollution, carbon dioxide emissions and other particulates are also neutralised. This offers significant environmental benefits for both port staff and local residents in the La Pallice area.

The development of this shore power supply infrastructure began in 2022 with the design phase. Port Atlantique La Rochelle allocated the necessary time to develop the prototype, engaging all relevant departments. In partnership with Enedis, the research focused on the best connection ergonomics, the greatest versatility of use and ease of operation. Although operating at low voltage (400 volts), the power supply terminals provide high power outputs (ranging from 250 to 600 amperes). Twelve power supply points have been installed, including nine built-in plugs along the quays around the Wet Dock, on Alcyone Quay, and Lombard Quay, as well as three power supply terminals on the dry docks and the southern quay (BF 17).

Connected to the port's hypervision system, the infrastructure can be continuously monitored. Invoicing is based on the real-time transmission of electricity consumption, once the user has activated their connection using a QR code or a badge issued by the port authority. It should be noted that, until the end of 2024, pricing will be incentive-based for all users. Initially, only the energy consumed will be invoiced. The service itself will not be billed until January, 1st, 2025.

Representing an investment of two million euros, the shore electrification project is co-financed to the extent of 50% under the "decarbonisation of port transit" component integrated into the French government's France Relance plan.
