The Joint Arrangement Nieuw Reijerwaard (GRNR) is committed to becoming the most sustainable agro/fresh/food logistics business park in Europe. This ambitious initiative is a collaboration between the municipalities of Rotterdam, Barendrecht, and Ridderkerk, aiming to establish a cutting-edge industrial hub for companies in the food processing industry.
One of the key challenges of this project is addressing the power demands in a location with an already congested electrical grid. To overcome this, DC Opportunities has introduced an innovative solution by installing a DC container to create a local direct current (DC) microgrid.
Sustainable Energy Solution
The DC microgrid is designed to power public lighting using solar energy collected from on-site solar panels. The DC container is equipped with all the essential components to maintain this microgrid, including:
- MPPT converters to maximize solar energy harvest
- Second-life batteries for energy storage
- BMS controllers for efficient battery management
- Bidirectional storage converters for energy distribution
- A bipolar DC microgrid operating at +/- 350V
- A balancing converter for voltage stability
- DC appliances and solid-state circuit breakers for grid protection
All of these components have been developed in-house, demonstrating the project’s commitment to innovation and sustainability. Through this cutting-edge technology, the project not only addresses energy constraints but also sets a new standard for sustainability in the agro/fresh/food logistics sector.
