Battery hybrid energy storage in the netherlands

Is S4 Energy launching a battery energy storage system in the Netherlands?

ROTTERDAM, Netherlands – 4 February 2025 – S4 Energy, Rotterdam-based leader in European grid-scale storage, has operationalized its state-of-the-art 4-hour Battery Energy Storage System (BESS), the first of its kind in the Netherlands.

Is this the first 4four-hour battery energy storage system in the world?

Rotterdam-based S4 Energy has commissioned a 10 MW / 40 MWh battery energy storage system (BESS) in Rilland, Netherlands, marking what the company claims is the first 4four-hour duration system of its kind in the country. The project’s 4-hour discharge capability distinguishes it from shorter-duration systems commonly used for frequency regulation.

What is a hybrid energy system?

This system is intended to assist the integration of more renewables into the grid. The Netherlands has ambitious targets for renewable energy generation, but this will need storage. The flywheels can store energy for a short time, and the batteries for longer, so the hybrid system will have more flexibility.

Will the Netherlands roll out 9GW of battery energy storage?

"By 2030, the Netherlands must roll out at least 9GW of battery energy storage to secure Europe’s balanced energy grid." The sophisticated BESS consists of 144 cutting-edge lithium-ion sealed cells -known as Fluence cubes - boasting a formidable capacity of 90MWh.
