System certificate A

For systems larger than 950 kW, a system certificate A must be submitted to the responsible energy supply company. This applies to both medium and high-voltage connections. The system certificate ensures that you and your grid operator can operate your system on the grid in a grid-compliant manner and thus guarantees you a permanent grid connection and permanent remuneration. The system certificate verifies all requirements from the grid connection guidelines with regard to the electrical properties of your generation system.

How does system certification work?

Which documents are required to create the system certificate A?

  • Data sheet with the technical data of the generation system (see form E.8)

  • For mixing systems: Mains feedback from the appliances (see form E.2)

  • Cover sheets of the unit certificates or the prototype confirmations and – if required – cover sheets of component certificates

  • Single-phase overview circuit diagram

  • Control concept incl. communication plan

  • Protection concept

  • Specification of the planned tap changer position of the machine transformers

  • For existing systems: Technical data of the existing generating units
  • Site plan incl. coordinates of the production units

Additional documents may be required for HV connections. You will receive a detailed checklist when you order the system certificate.
