Shore Power Market Summary

The global shore power market size was estimated at USD 2.22 billion in 2024 and is projected to reach USD 4.0 billion by 2030, growing at a CAGR of 10.6% from 2025 to 2030. The market is witnessing strong growth momentum, supported by the maritime industry’s transition toward cleaner and more sustainable practices. The rising emphasis on reducing greenhouse gas emissions and curbing dependence on fossil fuels is a key factor driving the increasing adoption of shore power systems at ports worldwide.

Shore power enables docked vessels to connect to onshore electricity, thereby shutting down their auxiliary engines and reducing both air and noise pollution. This approach not only improves environmental quality around ports but also enhances energy efficiency. With the growing pressure to adopt sustainable port operations, the demand for shore power infrastructure is rapidly accelerating.

Stringent environmental regulations are serving as a major catalyst for market expansion. International bodies such as the International Maritime Organization (IMO) have introduced strict emission limits for sulfur oxides (SOx) and nitrogen oxides (NOx). These mandates are compelling port authorities and ship operators to invest in shore power infrastructure. Additionally, heightened public awareness about air quality and its impact on human health is further pushing governments and port operators to embrace cleaner alternatives.
