Cost of a 100kW Mobile Energy Storage Container for 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.

Why is energy storage a critical port function?

Ensuring availability of these electrical resources to meet loads which are intermittent and uncertain is becoming a critical port function. It requires investment in multi-vector energy supply chains, energy storage in ports and their associated energy management systems.

What is a solar grid connection capacity?

• Grid connection capacity = 100kVA. The figures below show the battery behaviour in summer and winter, to observe the impact of seasonal PV solar variation. Performance of a system with 120kWp of PV solar capacity in Summer, showing the small amount of grid energy needed to supplement the solar power.

Is the battery capacity of 500kWh over-sized?

grid connection capacity means that the recharging duration would have to be at least 1.25 hours. This constraint could be operationally inconvenient for the operator. The battery state-of-charge results above indicate that the battery capacity of 500kWh is over-sized for this use-case.
