Project Description
Our company successfully completed the installation of a High Voltage Shore Connection (HVSC) system at the passenger port of Valletta, the historic capital of Malta, with the aim of implementing environmentally friendly and sustainable energy solutions. Through this system, cruise ships are supplied with green energy directly from shore during port stays, eliminating the need for diesel generators.

Project Scope
  • Design and implementation of high-voltage shore power infrastructure
  • Direct energy transfer to vessels via HVSC systems
  • Installation of underground cabling, transformer rooms, and power conversion systems
  • Integration of automation, safety, and remote monitoring infrastructures
  • Turnkey execution of all field applications and technical processes
  • Equipment totals: 64MVA Transformer, 98 Primary GIS units, 4×21MVA Dry-type Transformers, 4×19MVA Dry-type Transformers, 3×17MVA Dry-type Transformers, 1×7MVA Dry-type Transformer, 4×630kVA Dry-type Transformers
Technical Approach
The project was executed in accordance with IEC 80005-1 standards, constructing a high-voltage shore-to-ship connection infrastructure. The system supports three-phase shore power delivery in configurations of 6.6kV/50Hz, 6.6kV/60Hz, 11kV/50Hz, and 11kV/60Hz, and is equipped with flexible connector systems tailored to various ship structures.

Project Outcomes
  • Carbon Footprint Reduction: Approx. 5–10 tons of CO₂ savings per ship connection
  • Improved Air Quality: Decrease in NOx, SOx, and particulate emissions around the port
  • Energy Efficiency: More stable and lower-cost energy supply compared to onboard generators
  • Green Image: Alignment of Malta Port with EU Green Deal targets
Our Expertise and Approach
Through our experience in green port applications, agile project management methods, and international engineering team, we delivered a benchmark shore power system to Malta’s Valletta Port. In every aspect, sustainability, safety, and technical excellence were prioritized.
