Prequalification

The TSOs have defined uniform requirements for the information technology used by companies providing balancing services. These are found in the form of "IT Mindestanforderungen EN" 

Due to their system responsibility, TSOs generally maintain high requirements for the confidentiality, availability, and integrity of their infrastructures and information, which extend to all connected infrastructures and service providers. The requirements represent minimum standards for security and availability and provide further recommendations for achieving the desired goals.

The deliverance concept is the document in which the provider describes their provision and delivery. This includes, for example, the documentation of the technical implementation of the respective type of balancing services. You can find a guide for creating the concept here.

The operating test is a trial provision of balancing services. It is essentially a practical test based on standardized criteria, used to check the technical suitability of a provider's units for providing balancing services. The operating test is documented in an operational log, which the balancing service provider submits with the application documents.

The control system test is the final check performed by the connecting TSO to verify that the provider's control system connects correctly to the TSO's control system. Parts of the test include checking the correct collection and delivery of individual data points, receiving and accurately implementing setpoint values, and verifying redundant data connections. 

The test is carried out in close coordination between the provider and the TSO and is intended for all types of balancing services. The prequalification documents are submitted to the relevant TSO using the PQ portal. Access to the PQ portal can be requested from the respective connecting TSO.

The PQ portal is the central cross TSO database for the prequalification of TE/RE/RG. It needs: 

• Standardized collection and verification of the submitted data 
• Accelerated, transparent, and simplified PQ process 
• Application for access data from the connecting TSO necessary
