Key details

Fluvius publishes flexibility needs on NODES, specifying location, time window, and product type. FSPs respond with bids, which are evaluated based on cost-effectiveness, technical feasibility, and grid impact.

Once a Flexibility Service Provider (FSP) wins a bid for LongFlex™, the actual dispatch is sent through NODES.

After a dispatch, FSPs submit metering data via the NODES platform to confirm that the requested flexibility was delivered. Fluvius and NODES validate whether the activation met the agreed parameters.
