Technical FAQs 4

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.

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 much does a grid connection cost?

The complexity of grid connection requirements varies significantly based on location and local regulations, with costs ranging from €50,000 to €200,000 per MW of capacity. System integration expenses cover the sophisticated control systems, energy management software, and monitoring equipment essential for optimal battery performance.

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.
