Commissioning declaration

What is the declaration of commissioning and who issues it?

The commissioning declaration (IBE) is part of the verification process as part of the grid connection of a generation system or storage facility. You can find the entire verification process here. As part of the commissioning process, either the subscriber himself or a qualified body commissioned by him must provide proof that the generation system has actually been installed in accordance with the specifications of the relevant VDE application rule and taking into account the specifications of the grid operator.

What does the declaration of commissioning contain?

The IBE is prepared by the connectee on the basis of commissioning protocols, which may be supplemented by measurement protocols. The commissioning declaration is based on complete documentation of the commissioning and the installed generation system. Together with the system certificate, the declaration of commissioning forms the basis for the declaration of conformity of the generation system. This proves that the generation system meets the requirements of the VDE application rule, taking into account the grid operator’s specifications. The verification process is completed by the declaration of conformity. The final operating permit can then be issued by the grid operator.

What documents are required for the declaration of commissioning?

  • Function protocol for active and reactive power control

  • Protocol for checking the Q characteristic function or the data range for P and Q

  • Protocol for checking the behavior in the event of failure of the default values for P and Q and in the event of communication failure between the EZA controller and generating units
  • Test logs of the protective devices at the grid connection point and at the individual generating units
  • Setting protocols of the generating units

  • Setting protocol of the EZA controller

  • Power balance verification of UPS at NAP and, if applicable, intermediate protection devices
  • Commissioning protocol for the generator transformers

  • Proof of arc fault qualification of the switchgear

  • Test protocols of the current and voltage transformers

  • Test reports of the billing and (if available) the comparative measurement

  • Type test protocols of the installed protective devices (for external protective devices)

  • Manufacturer’s declaration on the parameter set of the generating units
  • Energy flow direction detection for storage systems
