What is the Shore to Ship Power Supply Market?

The increasing enforcement of global maritime decarbonization regulations is a major driver accelerating the adoption of shore-to-ship power supply systems worldwide. Shore-to-ship power, also known as shore power or cold ironing, is an advanced port electrification technology. It permits docked ships to close the onboard diesel auxiliary engines and be tied to landside electric grids. This connection provides onboard lighting, ventilation, cargo handling equipment, and hoteling operations with electricity during berthing periods. Furthermore, the growing regulatory pressure and urgent need to reduce port emissions continue to strongly drive shore-to-ship power supply market expansion worldwide.
