Shore power and energy storage

What is shore power?

Shore power refers to the possibility for a ship to plug in to an onshore electricity grid when in port. With shore power, the vessel does not have to use its auxiliary engines to generate power. This decreases emissions and noise. Shore power can also be used to charge the energy storage system on board the ship. shore power connection.

What is ship shore power technology?

Ship shore power technology refers to the practice of shutting down the ship’s own diesel auxiliary generator and using the power system on the dock to provide electricity to the vessel. This way, electrification from shore to ship can be achieved.

How do shore power solutions help ships save fuel and reduce emissions?

Shore power solutions from Wärtsilä help vessels save fuel and decrease their emissions because they can plug in to the onshore electricity grid when in port. Without shore power, the vessels would have to use auxiliary engines to generate power.

What is a shore power facility?

Shore power facilities will generally form part of a wider port energy network including electric power for port assets and back-up power generators. Ports that have a high-power grid connection (or could upgrade their connection at reasonable cost) do have the option of supplying shore power directly from the grid.

What is a shore power solution?

Shore power solutions that are integrated with the port’s (50Hz) electrical network are more complex. The optimization of energy storage in batteries, taking account of variable wholesale electricity pricing and serving highly variable shore power loads, is a complex and specialist role.

How does shore power work on a ship?

On the ship an incoming panel is placed in a confined room, where the operator connects the ship to shore power. The power is often via a transformer (if ship grid is low voltage) connected to the main switchboard. The Wärtsilä shore power control system and built in safety features ensures safe and seamless operation.
