The Market Operator informs market participants, in particular prospective aggregators and flexibility providers, that the information system now allows the submission of applications for the assignment/change of an aggregator for metering points that will provide flexibility from 1 September 2026.

The Market Operator reminds aggregators and flexibility providers that, under the applicable legislation, the process of being assigned as an aggregator/flexibility provider takes at least 10 working days. It is therefore recommended that the assignment of balance responsibility for imbalances caused by the provision of flexibility (i.e., setting up the so-called aggregator balance responsible party for aggregate EANs) be completed first, and that applications for assigning the aggregator to the physical EAN metering points that will provide flexibility from 1 September 2026 be submitted as soon as possible and for the earliest possible effective date. This should be done well in advance to ensure that both the aggregator and the aggregator BRP are assigned to the relevant physical EAN metering points no later than 1 September 2026. In the relevant application for the assignment/change of an aggregator for physical EAN metering points, the earliest date that may be entered as the “effective from” date is the nearest day for which the statutory deadline for submitting the application has not yet expired, i.e., 10 working days before the requested effective date.

In this context, the Market Operator again expressly draws attention (especially to aggregators and flexibility providers) that, in the case of generation metering points registered using two paired EANs (an EAN for export/supply data and an EAN for import/consumption data), the relevant application for the assignment/change of an aggregator in the Market Operator’s system must always be submitted for both EANs simultaneously. Otherwise, the application will be rejected.
