Market access and prequalification: control reserve.
Potential providers for the different types of control reserve can participate in a prequalification procedure in which they provide evidence that they meet the requirements necessary to ensure security of supply for the provision of one or more types of control reserve.
For all types of control reserve (FCR, aFRR, mFRR), prequalification takes place exclusively with the TSO in whose LFR zone the relevant technical units (power generation plants and/or consumption units) are connected to the grid, irrespective of the voltage level (connection TSO). With the revision of the Prequalification Conditions ("PQ Conditions") of October 2018, prequalification is based on the prequalification of reserve units and reserve groups.
As soon as the prequalified marketable capacity exceeds the respective minimum offer size, the connecting TSO concludes a framework agreement with the reserve provider for each control reserve type (see downloads opposite), which in turn is a prerequisite for participation in the bidding procedures for control reserve.
Prequalification is possible at any time. The implementation of a corresponding prequalification procedure usually requires a period of at least two months after the complete submission of all required documents, protocols and evidence. Depending on the complexity, a longer period may also be required.
Technical requirements (PQ conditions)
Commission Regulation (EU) 2017/1485 of 02 August 2017 establishing a guideline for transmission system operation (hereinafter "SO GL") entered into force on 14 September 2017. The SO GL contains, among other things, requirements for the prequalification procedure for control reserve providers, the implementation of which in Germany is the responsibility of the German transmission system operators 50Hertz Transmission GmbH, Amprion GmbH, TenneT TSO GmbH and TransnetBW GmbH (hereinafter "TSOs").
The TSOs have revised and published the prequalification conditions ("PQ Conditions") for the control reserve types FCR, aFRR and mFRR.
IT requirements (minimum IT requirement)
Due to new technologies in the field of information technology, new types of possibilities for reliably transmitting data are emerging. To take account of this development, the transmission system operators (TSOs) have defined uniform requirements for companies that provide or wish to provide services in the area of balancing power in the form of the "Minimum requirements for the information technology of the provider for the provision of balancing power".
Due to their system responsibility, the TSOs must generally comply with high requirements for the confidentiality, availability and integrity of their infrastructures and information, which are transferred to all connected infrastructures and service providers. The requirements represent minimum requirements for security and availability and provide further recommendations for achieving the intended goals.
All relevant documents are published under the adjacent links.
The prequalification documents can be submitted to the relevant TSO by using the PQ portal.
