A declaration of conformity can only be issued based on a valid plant certificate and a complete and accurate commissioning declaration (E.11), including the required annexes. The declaration of conformity must be accompanied by the commissioning declaration of the generation system, including the associated protocols and evidence.
The declaration of conformity confirms that the entire generation system complies with the applicable VDE application rules (41xx), the supplementary technical connection conditions of the grid operator (TAB), and the specifications in the plant certificate. Plant certification is complete when the declaration of conformity is issued. It must be submitted to the grid operator within the plant certificate's validity period.
VDE Application Rules 41xx refer to commissioning a generation unit (PGU) or a generation plant (PGU). Accordingly, the commissioning dates of the first and last PGUs must be used to determine the validity. Therefore, please provide us with the commissioning dates of all PGUs as soon as possible.
The applicable deadlines are set out in VDE Application Rules 41xx and FGW TR8 (current version). According to these documents, the declaration of conformity must be submitted to the grid operator by the following deadlines: Six months after the commissioning of the entire generation system and no later than 12 months after the commissioning of the first newly certified generation unit.
In accordance with the FGW-TR8 guideline, the validity of the plant certificate can be extended. However, an extension is only possible by prior agreement between the grid operator and the certification body and in justified cases.
The system operator or a competent body commissioned by the operator (e.g., an electrical planner, operations manager, or system installer) can draw up a commissioning declaration based on the commissioning logs and other documents.
A certification body that is accredited according to DIN EN ISO/IEC 17065 may issue a declaration of conformity based on a plant certificate and a complete, accurate declaration of commissioning. The entities issuing the declaration of commissioning and the declaration of conformity must be organizationally separate.
