What is the Modular Offshore Grid?

The Modular Offshore Grid (MOG) is a strategic infrastructure project designed to integrate multiple offshore wind farms in the Belgian part of the North Sea into a cohesive transmission network. Rather than relying solely on individual point-to-point shorecables for each wind farm, the MOG creates a shared grid backbone that enhances flexibility and resilience. Rentel is one of the wind farms connected to this system, allowing it to transmit power to the Belgian mainland through the MOG infrastructure in addition to its dedicated shorecable.

Network Architecture and Function

The MOG concept involves interconnecting several offshore wind farms with each other and with the onshore grid. This modular approach means that power from one farm can be routed through another, reducing the dependency on a single transmission line. For Rentel, this dual connectivity proved critical. The wind farm has a cable to shore, but is also connected to the Modular Offshore Grid, providing a secondary pathway for electricity transmission. This architecture supports the growing capacity of the Belgian offshore wind sector, which includes Rentel as the fifth offshore wind project in the region.
