Currently, generation and storage units with an installed capacity of 25 MW or more, which are connected to the Elia grid, are obliged to provide active power schedules and flexibility information and thus to be covered by a Scheduling Agent Contract.
Other technical units can also be included in a contract in order to participate in the coordination process carried out by Elia (units that can have a serious impact on the Elia network) or in order to offer specific ancillary services (if a Scheduling Agent Contract is a condition for the provision of the service).
