Off-grid cost of energy storage containers for European ports

How can ports reduce energy costs?

ESSOP has explored two ways in which ports can minimize their energy costs by using energy storage: • Optimising how to use PV solar generation to offset grid electricity. The wholesale price of energy varies every half-hour, and on a time-of-day tariff this variation is passed onto users.

How can ports reduce the dependence on grid-supplied electricity?

To minimize the dependence on grid-supplied electricity, ports are also investing in renewable generation notably PV solar on warehouse roofing and parking areas. Energy storage is also needed to optimize utilization of in-port generation and avoid curtailment when generation exceeds the available demand.

How to electrify container handling equipment?

For electrification of container handling equipment and other port equipment, it is important to not only look at the investment costs and total costs of ownership, but it is also important to regard the electricity grid capacity within port areas. If this is not possible, contact with the electricity network operator is necessary on forehand.

Can ships plug into the local electricity grid while docked?

This measure will allow ships to plug into the local electricity grid while docked, replacing the use of fossil-fuel auxiliary engines and reducing harmful emissions. The study by DNV on behalf of T&E shows that only one in five required onshore power supply (OPS) connections is currently installed or contracted, with slow uptake across most ports.
