PSW Power & Automation innovates onshore power supply solutions for cleaner ports

While shore power systems have been around for some time, their availability is still limited. Ships without a shore power connection normally use their diesel engines to power the vessel in port, resulting in significant CO₂ emissions and noise pollution.

According to the EU Alternative Fuels Infrastructure Regulation (AFIR), all European ports must provide shore-side electricity by 2030. To reach this target, easy-to-use connections to the main power grid are essential.

PSW Power & Automation (PSW) provides a range of solutions. These include medium voltage shore power solutions for cruise and container harbours in accordance with IEC 8005-1, as well as low voltage solutions in accordance with IEC 8005-3. The shore power systems typically include input and output switchgear, transformer solutions, AFE and grid inverter, as well as optimised solutions to upgrade and strengthen the infrastructure of the local grid and port network.

PSW’s shore power solutions also provide vessel to grid functionality, enabling vessels to become a local power source towards the local grid.

PSW’s dynamic megawatt charging system transfers power from the electrical grid to onboard batteries. The system automatically charges vessels according to power ramp (based on grid capability) and dynamic power limit (based on available charging time and electricity price).

PSW provides optimised energy storage solutions for onshore power supply solutions as well.

PSW’s systems are highly flexible and can be integrated with alternative energy sources such as renewables, quayside charging infrastructure and grid stabilisation services.

PSW enables vessels to achieve low or zero emissions and noise pollution. Its shore power solutions efficiently match frequency and voltage and swiftly react to power dynamics to ensure a reliable, streamlined connection for ships.

Cruise ships and offshore vessel owners are utilising onshore power facilities far more than the ports expected. The benefits of reduced maintenance on machinery, less noise on board, fewer crew members on watch, and significantly lower emissions motivate ships to connect whenever shore power is available.

The global market potential for shore power solutions is enormous, and demand will continue to rise in Europe, as the EU AFIR compels rapid development of shore-side electricity. Similarly, more countries are tightening up their legislation and will likely follow Norway’s lead of enabling cruise and cargo ships to shut down auxiliary engines while docked.

PSW exports its solutions worldwide.
