Market Overview

The shore power market has emerged as a crucial component in global sustainability efforts, especially within the maritime and shipping sectors. Also known as "cold ironing" or "alternative maritime power," shore power allows ships to plug into a port’s electrical grid while docked, thereby reducing reliance on onboard diesel engines. This transition significantly contributes to vessel emissions reduction, particularly lowering nitrogen oxides (NOx), sulfur oxides (SOx), and carbon dioxide (CO₂) emissions.

The global shore power market size was valued at USD 2,059.37 million in 2024, growing at a CAGR of 11.4% from 2025 to 2034. The market growth is primarily fueled by the growing demand for cleaner energy sources and the introduction of stringent emissions regulations worldwide.

Market Scope

1. Environmental Regulations and Policy Support
   Global and regional regulatory frameworks targeting vessel emissions reduction are driving demand for shore power systems. International Maritime Organization (IMO) policies and regional emission control zones have created a favorable environment for adoption.
2. Integration with Renewable Energy Sources
   Ports are increasingly adopting renewable energy integration, linking shore power systems to solar, wind, and hydropower grids. This integration strengthens sustainability credentials while reducing dependency on fossil fuels.
3. Rising Investments in Port Infrastructure
   Governments and private stakeholders are investing heavily in modernizing port infrastructure to accommodate shore power systems. This includes upgrading electrical grids, transformers, and substations at terminals to ensure reliable power supply.
4. Shift Toward Marine Electrification
   With the global shipping sector moving toward marine electrification, shore power systems are recognized as an essential step in reducing the industry’s overall carbon footprint while enabling compliance with stricter emission norms.
