Shore Power Market Is Plugging Ships Into the Grid as Ports Race to Cut Emissions at the Berth

The Shore Power Market was valued at USD 2.20 billion in 2025 and is estimated at USD 2.44 billion in 2026. It is projected to reach USD 5.81 billion by 2034, growing at a CAGR of 11.4% from 2026 to 2034. Two forces are driving this expansion. Demand for cleaner energy is rising, and emissions regulations are tightening around the world. Shore power, also called onshore power supply or cold ironing, lets ships switch off their auxiliary engines at the quay and draw electricity from the local grid.

Why Ports Are Switching

A docked vessel running diesel generators releases carbon dioxide, nitrogen oxides, sulfur oxides and particulates into the air of the surrounding city, along with engine noise. Shore power produces near-zero emissions at the berth, lowers fuel and engine maintenance costs and reduces noise. Its main limitation is that it depends on port infrastructure and grid compatibility, so ships still carry generators for ports that lack connections. The health case is strong. A June 2024 ICCT report estimated that shore power at the Port of Seattle could cut CO2, NOx and PM2.5 emissions by 68%, 85% and 75% respectively.

Regulation Is the Main Engine of Growth

The EU’s FuelEU Maritime Regulation took effect on January 1, 2025. It requires a gradual reduction in greenhouse gas intensity for ships over 5,000 gross tons calling at EU ports, with targets of 2% by 2025 and 80% by 2050 against 2020 levels. From 2030, ships must use onshore power or zero-emission technologies while docked. The EU’s REPowerEU plan and the Alternative Fuels Infrastructure Regulation add binding port electrification targets. Meanwhile, the International Maritime Organization has set limits on sulfur and nitrogen oxide emissions, and emission control areas are pushing ports to invest. Longer ship turnaround times and growing trade volumes add to the need for sustainable port infrastructure.

Technology Is Making Connections Easier

Shore power systems are becoming smarter and more flexible. High-voltage shore connection systems support large cruise ships and container carriers. Automated shore-to-ship connections reduce connection time and improve safety. Advanced frequency converters allow ships and ports with different electrical standards to work together. AI-based energy management predicts demand and improves grid coordination, and remote monitoring with predictive maintenance reduces downtime. Modular designs let smaller ports expand in phases. Cybersecurity is gaining importance as these systems become more connected. In April 2026, Cavotec launched PowerMove RoRo NxG, a next-generation mobile cable management system designed to simplify shore power connections for RoRo and RoPax vessels.

Segment Insights

By installation type, shoreside installations held the largest share, 45.0%, in 2025. Major ports have deployed shore power infrastructure widely, particularly in emission control areas in Europe and North America, and centralized power distribution supports reliable connections. Other categories include shipside, passenger vessel, merchant vessel, offshore support vessel and specialized vessel installations.

By connection type, retrofit is expected to grow fastest, at 10.16%. Shipping companies would rather upgrade existing vessels than buy new ones, and government subsidies encourage the work. By component, frequency converters accounted for a 30.0% share in 2025 because they are the most technically complex and highest-value item in a shore power system. Transformers, switchgear and cables and accessories complete the equipment mix.

Regional Outlook

Asia Pacific led in 2025 with a 36.0% share. Extensive maritime trade, rapidly expanding ports and stringent rules in China, Japan and South Korea support the region, and busy hubs such as Shanghai and Singapore are accelerating adoption. India is also expanding shore power at major ports under its Harit Sagar Green Port Guidelines.

North America is expected to grow fastest, at 11.12%. Strong environmental policy and port modernization funding drive it, including federal infrastructure funding for port improvement projects announced by the U.S. Maritime Administration in November 2024. Mandates apply at major ports such as Los Angeles, Long Beach and Vancouver. In November 2025, MSC Meraviglia connected to shore power at New York’s Brooklyn Cruise Terminal, allowing engine-off operation while docked.

Recent Port Projects

Europe continues to lead on large projects. In January 2026, ABB signed contracts with Rotterdam Shore Power to engineer and build multiple installations at the Port of Rotterdam, described as the world’s largest shore power project. In November 2025, the Port of Oslo waived quay fees for vessels using emission-free shore power. In January 2025, the Port of Aarhus announced Denmark’s first shore power facility for container ships. In September 2025, Wah Kwong, NatPower and SPG partnered to advance shore power and ship charging projects in Asia.

Competitive Landscape

Leading companies include ABB, AEG Power Solutions, BluEco, Cavotec, Danfoss, Eaton, Emerson Electric, Engie, GE Grid Solutions, Konecranes, Powercon, Schneider Electric, Siemens and Wärtsilä. Schneider Electric and Wärtsilä focus on efficiency and emissions reduction, while ABB offers cost-effective modular solutions suited to emerging markets. Eaton supplies ship-to-shore connectors and marine power products. Companies are pursuing regional expansion, renewable energy integration and digitalization.

Challenges and Opportunities

High upfront costs are the main restraint, since ports must invest in grid upgrades, substations and berth equipment, and ships may need retrofits. Government grants, port fee incentives and modular designs can reduce that burden. Opportunities lie in green port development and in linking shore power with renewable energy such as solar and wind, so that the electricity ships use is itself low-carbon.

Shore Power Market growth through 2034 will depend on regulatory enforcement, falling technology costs and continued port electrification. Retrofits will bring existing fleets into the system, while new installations will serve growing cruise, container and ferry traffic. Suppliers that offer interoperable, scalable and digitally managed systems, and that help ports connect to clean grids, will be best placed to benefit as the shipping industry works to lower its footprint.
