This makes shore power a more viable option for a wider range of vessels.

Connection Insights

The retrofit segment held the largest revenue share in 2024. The increasing global demand for sustainable port operations has driven ports and shipping companies to invest heavily in retrofitting existing vessels with shore power capabilities. The inability of older ships to interface with shore-based electrical systems makes retrofitting a necessary step to enable these vessels to reduce their reliance on auxiliary diesel engines while docked. This approach allows operators to meet emission reduction targets without requiring complete vessel replacement, thereby offering a cost-effective and timely solution. Technological advancements have made retrofitting processes more efficient and cost-effective. Furthermore, stricter environmental regulations incentivize ship owners to explore retrofitting to comply with emission standards.

Financial incentives offered by governments and organizations further enhance the attractiveness of retrofits. These incentives help offset the upfront costs of modifying vessels, making shore power a more accessible solution for a broader range of ship operators. As the focus on environmental sustainability intensifies, the retrofit segment is expected to play a vital role in transitioning the maritime industry toward a cleaner future.

Component Insights

The frequency converters segment dominated the market in 2024. Its critical role in ensuring compatibility between onshore electrical grids and shipboard power systems makes it a preferred option. It enables seamless synchronization of voltage and frequency, allowing vessels to safely and efficiently connect to shore-based electricity regardless of regional grid specifications.Furthermore, as more ports invest in shore power systems worldwide to meet environmental regulations and sustainability goals, the demand for high-performance, flexible frequency converters continues to rise.

Transformers is expected to be the fastest-growing segment over the forecast years. They play a critical role in shore power systems and help adjust the voltage level of incoming electricity from the land-based grid to match the specific voltage requirements of the docked vessel. This ensures safe and efficient power transfer between the shore and the ship.

Power Rating Insights

The up to 30 MVA segment dominated the global market in 2024. This trend aligns with the increasing dominance of mega-ships in international maritime transportation.
