Located near Dronten, in Flevoland, a central part of the Netherlands, the system will support the region’s ambitious energy transition goals by stabilizing the grid, enabling renewable integration, and preparing for future expansions to 204MWh by 2028. The agreement was signed in December 2024 and installation is on track for completion in the third quarter of 2025.
"The Alfen team is very proud of the intensive preparatory phase with FlevoBESS and to partner with them on such a landmark project, both in terms of size and solutions," said Stephanie Schockaert, Commercial Director for Alfen’s Energy Storage Solutions.
"This system marks a significant step forward in energy storage capacity and technology, demonstrating our ability to deliver large-scale, future-ready solutions for our customers."
This project leverages Alfen’s expertise across multiple businesses to deliver a comprehensive energy storage solution. It integrates Alfen’s latest generation of battery containers, which have an exceptional energy density of up to 4MWh within a 20 ft container.
This design enables efficient back-to-back and side-by-side installations, significantly reducing the required footprint. Paired with Alfen’s largest inverters on the market, these containers deliver up to 4 hours of discharge capability to increase demand for energy solutions that can handle longer durations of supply and demand balancing.
Alfen’s Smart Grids team will provide a high-capacity walk-in substation to enable seamless integration with the local energy infrastructure, while the Energy Storage Systems team will deploy 6 7.5MVA subsystems.
“Alfen’s innovative 4-hour solution optimizes space and incorporates the latest safety and operational advancements to ensure greater reliability and efficiency,” Schockaert said. “We’re proud to partner with FlevoBESS to introduce this innovation advancement and demonstrate Alfen’s commitment to offer scalable and forward-looking energy solutions.
FlevoBESS is a consortium of local entrepreneurs and participants from the Flevoland region, united by their commitment to advancing sustainable energy solutions and fostering regional economic growth.
“The FlevoBESS project is built on collaboration and innovation across multiple stakeholders,” said Gert Naber, board member of FlevoBESS. “Our consortium is committed to making a real impact in the region by driving local engagement and making sustainable progress. We chose Alfen as a key partner for their proven track record in developing innovative, sustainable energy storage solutions and their dedication to making this project successful.”
