Cádiz Milestones: Spain’s First Cruise Shore Power System Goes Live
The Port of Cádiz has achieved a landmark victory for Mediterranean port electrification, officially launching the first Onshore Power Supply (OPS) system for cruise ships in Spain. The milestone was marked at the Muelle Alfonso XIII quay as the Viking Saturn (Viking Cruises) successfully "plugged in," allowing the vessel to shut down its auxiliary engines and draw clean energy directly from the city's grid.
Engineering the "Last Meters"
The technical success of the project hinges on the sophisticated management of the connection between the stationary quay and the moving vessel. Spanish maritime specialist TEC Container played a decisive role, designing and manufacturing the Cable Management Units (CMUs) that serve as the critical link in the chain.
Unlike static shore connections, the Cádiz solution utilizes a mobile connection device equipped with a high-tech articulated arm. This system is specifically engineered to handle the "real-world" complexities of a working cruise berth:
- Three Degrees of Freedom: The arm utilizes two rotations plus a telescopic displacement to reach the ship’s receptive plug with precision.
- Tide Compensation: Using motorized mono-spiral reels and automatic positioning, the CMU maintains safe cable geometry, automatically adjusting as the ship rises and falls with Atlantic tides and fluctuating freeboard levels.
A Data-Driven Environmental Shift
The environmental impact of the new installation, provided by a consortium including Endesa and TEC Container, is backed by significant figures. According to data from SMARTGRIDSINFO, the system is projected to supply 8.62 GWh in its first year alone.
The transition from auxiliary generators to shore power—supplied by Endesa with renewable origin certificates—is expected to deliver the following annual benefits:
- CO₂ Reduction: ~5,000 tonnes (equivalent to removing 2,800 cars from the road).
- NOx Emissions: Cut by up to 96%.
- Particulate Matter (PM): Cut by 94%.
- SOx Emissions: Cut by 8%.
A Strategic Benchmark for Spanish Ports
This launch follows TEC Container’s previous success in the Port of Palma three years ago, where they supplied shore power to Spain’s first ferry. By now successfully scaling this technology to the cruise sector, the company and the Port of Cádiz have set a new national standard.
For a port located directly adjacent to a dense urban center, the elimination of both stack emissions and engine noise represents a significant improvement in the relationship between the maritime industry and the local community.
Cádiz has proven that the infrastructure is not just a regulatory goal, but a functional, operational reality.
