Ship to Shore Charging

SHIP TO SHORE CHARGING

Plugging Ships in to a Cleaner Future

As environmental concerns grow, more ports and shipowners are turning to shore power as a way to cut emissions while ships are docked.

Instead of relying on onboard diesel generators, ships can connect to a land-based power source, reducing air pollution and improving energy efficiency.

WHY SHORE POWER?

With the global push for cleaner energy and sustainable solutions, the maritime industry is evolving. Many shipowners are adopting technologies like high-efficiency motors, electric propulsion, variable-speed drives, energy storage systems, and improved hull materials to reduce emissions. At the same time, port operators are integrating electrical infrastructure into new and existing facilities to make operations more sustainable without sacrificing profitability.

The shipping industry is responsible for moving around 90% of global goods, and as trade continues to grow, emissions from port operations are a significant concern. While docked, ships typically run their diesel generators to power onboard systems, releasing pollutants like CO₂, NOx, SOx, and particulate matter. In busy city ports or environmentally sensitive areas, these emissions can contribute to major air pollution problems.

HOW SHORE POWER WORKS

To address this issue, many ports use high-voltage shore connection (HVSC) technology, allowing ships to switch off their diesel generators and draw power directly from the shore. This system supplies electricity at voltages between 1–11 kV, delivering multiple megawatts of power to large vessels. Typically, HVSC is used for ships requiring over 1 MW of power while berthed.



By plugging into shore power, ships can significantly reduce emissions during their stay at port. Electricity is provided through a dedicated cable system, often sourced from renewable energy, and is offered to vessel operators at competitive rates

SHORE POWER FOR DIFFERENT VESSELS

While passenger ships are among the early adopters of shore power, other vessel types are also beginning to use this technology. As ports and regulatory bodies continue pushing for cleaner alternatives, shore power is becoming a key part of the maritime industry's shift toward sustainability.
