Ship-to-Shore Power
More Info
Shore Power Solutions for Ports, Terminals, and Vessels
Reduce emissions. Meet compliance. Power safely.
Shore power, also known as cold ironing, refers to supplying electricity from the port to a vessel while it’s docked. This allows the ship to shut down its onboard diesel engines and operate on cleaner utility power instead. With growing regulatory pressure from CARB, IMO, and other governing bodies, shore power is no longer optional. It’s becoming essential infrastructure for modern port operations.
At ESL, we provide custom-engineered shore power solutions built for the unique needs of each installation—trusted by commercial ports, military shipyards, and cruise facilities across North America.

Frequently Asked Questions
Shore power, also known as cold ironing, Onshore Power Supply (OPS), or Alternative Maritime Power (AMP), allows a docked ship to plug into utility power and turn off diesel generators. This reduces fuel use, emissions, and noise while supporting compliance with environmental regulations.
Commercial container ships, cruise liners, Ro-Ro vessels, ferries, and military ships all benefit from shore power, especially in regions with emissions regulations or sustainability goals.
In many regions, yes. Regulations like the CARB Shore Power Rule and IMO MARPOL Annex VI require certain vessels and ports to reduce emissions at berth. Shore power is one of the most effective ways to comply with these standards and future-proof your operations.
