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 information about planned or forced outages and thus to be covered by an Outage Planning 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 seriously impact the Elia network) or in order to offer specific auxiliary services (if an Outage Planning Agent Contract is a condition for the provision of the service).
