Electrical Certification

Manufacturers of power generating units (PGU), project planners and operators of power generating plants (PGP) of any technology are obliged to prove the grid compatibility and integration of their product or plant through certification. Accredited by the German Accreditation Body (DAkkS), WindGuard Certification is your experienced partner for unit and plant certification. We are at your side during the whole process. From testing and measuring to proving electrical properties in accordance with the applicable guidelines, WindGuard Certification will accompany you all the way to the successful operation of your system.

Certification of Power Generating Units (PGU) and Components

In order to obtain approval for connection to the public grid, power generating units such as wind turbines, inverters for solar energy, combined heat and power plants and energy storage units require a unit certificate. It proves on a type-specific basis that the power generating unit is suitable for its intended operation in the low, medium, high or extra-high voltage grid and complies with the corresponding grid connection guidelines. Since certain equipment such as protective devices and controllers can also significantly influence the required electrical properties, their suitability must be verified by component certificates.

Unit and component certification are prerequisites for obtaining the system certificate for the operation of the generation system.

From the review of the manufacturer's documentation and the verification of the electrical characteristics by means of suitable tests and measurements in our own test laboratory to the issuing of the certificate and the detailed evaluation report, our experts accompany you through the entire certification process.

Guidelines for Certification of Power Generating Units (PGU)


Guidelines applicable for the certification of your power generating unit (PGU):

  • FGW TR 8
  • VDE-AR-N 4105
  • VDE-AR-N 4110
  • VDE-AR-N 4120
  • VDE 0124-100
  • CEA, Central Electricity Authority (India)
  • CEI 0-16, Comitato Elettrotecnico Italiano (Italy)

In addition to the certification procedures accredited by the Deutsche Akkreditierungsstelle GmbH (DAkkS), we also offer you conformity studies to demonstrate compliance with international grid connection guidelines.

Certification of Power Generating Plants (PGP)

Operators of power generating plants (PGP) with a total output of 135 kW or more must submit a plant certificate before or at the time of commissioning of the plant. In the case of plant certification, WindGuard Certification considers the power generating plant, for example the wind or photovoltaic farm or the combined heat and power plant, as a whole entity as early as the planning phase. The aim of the certification is to prove that the plant, with its entire electrical infrastructure for connection to the grid, complies with the guidelines and that safe grid operation is guaranteed. The plant certificate is a prerequisite for commissioning the plant.

Our experienced team will also accompany you through to the regular operation of your system. Our test laboratory offers to prepare the required commissioning declaration, and finally we will check whether the finished system complies with the planning and issue you with the corresponding declaration of conformity. This declaration of conformity is a prerequisite for permanent operation and confirms that your project has been implemented in compliance with the guidelines.
