The introduction of the shared call for tenders for FCR has given connecting TSOs a key role to play. A connecting TSO is a TSO in the control area of which the technical units to be marketed by the supplier are connected to the grid, irrespective of the voltage level. The connecting TSO conducts thePrequalification procedure for these technical units (e.g. generating units or controllable consumer loads) in its control area and is the sole contracting party of the supplier. If a supplier offers technical units in several control areas, a framework agreement has to be concluded with each respective connecting TSO. A precondition for concluding such a framework agreement is a successful prequalification, whereby the prequalified capacity must at least equal the minimum offer capacity. The framework agreement is a precondition for taking part in a joint tender for FCR.
www.regelleistung.net is used to publish the calls for tenders, process the submission of offers and inform providers about their awarded or rejected bids.
The call for tenders for FCR is 'symmetrical', meaning there is no separate call for tenders for positive FCR (additional power) and negative FCR (less power).
