Shore power, also known as cold ironing or onshore power supply, enables ships to connect to the local electrical grid while docked at ports, allowing onboard diesel generators to be switched off. This technology significantly reduces greenhouse gas emissions, air pollutants, noise levels, and fuel consumption during vessel berthing. Shore power systems are increasingly being deployed across container terminals, cruise ports, ferry terminals, Ro-Ro facilities, naval bases, and multipurpose ports as governments and port authorities accelerate maritime decarbonization and environmental compliance initiatives.
Market Overview
The Shore Power Market is projected to grow from US$ 2.51 Billion in 2025 to US$ 5.83 Billion by 2034, registering a CAGR of 9.82% during the forecast period 2026–2034. Market expansion is driven by increasing investments in port electrification, stricter emissions regulations, government funding for sustainable port infrastructure, and growing adoption of grid-powered berths to reduce emissions from docked vessels.
