Combustion engine/ combined heat and power unit

Since 1st January 2014, combustion engines (total apparent power of over 1 MVA at the grid connection point or a medium voltage cable length above 2 km) which are unable to meet the grid connection guidelines and the statutory requirements, cannot go online.

According to BDEW guideline including all four supplements and TransmissionCode 2007, combustion engines on medium, high and very high voltage grid must be certified in Germany. The certification process of the combustion engine/ combined heat and power unit is two-tiered:

  1. System Certificate (Planning Certificate)
  2. Declaration of Conformity for the power generation plant

We recommend grid assessment and studies in advance for the larger combustion engine/ combined heat and power unit or mixed farms.

We assist you with all of your queries.

For combustion engine/ combined heat and power unit less than 10 MVA:

  • The respective plant operator must submit the unit certificate until 30 June 2015 and the system certificate until September 30, 2015 to the respective grid operator.

For combustion engine/ combined heat and power unit above 10 MVA:

  • The plant operator must provide the evidence of the electrical properties of the power generation plant at the grid connection point to the grid operator. The confirmation of the dynamic grid support and also availability of the power generation plant in the grid during the grid fault are not required.
  • The evidence of the dynamic grid support and availability of the power generation plant in the grid during the grid fault must be provided as part of the further necessary confirmation of the unit and system certificate to the responsible grid operator by 31st December 2016.

Our MKH Greenergy Cert GmbH team have adequate knowledge and experience with the electrical properties of your power generation plants in accordance with the current statutory grid connection requirements. We will ensure that your combustion engine/ combined heat and power unit takes the leading role in the energy transition.

In the first phase, we issue the system certificate (planning certificate) in accordance with the technical guidelines of FGW (TR8) based on the positive results of our assessment for the grid connection, then the power generation plant can be used for the operation. This allows you to receive the remuneration for your project.

In the second phase, the final confirmation is provided by issuing the declaration of conformity for the power generation plant.

You can use the extensive experience of our employees in dealing with the legal grid connection requirements.

After commissioning of your combustion engine/ combined heat and power unit, the certification process is completed with the issuance of a declaration of conformity for the power generation plant. The system certificate only confirms that the power generating plant can basically meet the requirements of SDLWindV in connection with relevant current statutory grid connection requirements.

During the process of the declaration of conformity for the power generation plant, the planning certificate is verified for its implementation. The declaration of conformity is issued as evidence which finally confirms that the built power generation plant actually meets the requirements of SDLWindV at the grid connection point.

The system certificate (planning certificate) is initially valid until 6 months after the commissioning of last power generating unit of the respective power generation plant. The validity of the system certificate ends on the date of issue of the declaration of conformity for the power generation plant.

Reliability and cost effectiveness of the grid connection of your combustion engine/ combined heat and power unit is especially important for you!

We provide necessary support during the planning phase:

  • Assessment of the power losses
  • Load flow and short circuit calculations
  • Dynamic calculations
  • Assessment of the network disturbances and
  • Confirmation of the reactive power capability.

With our expertise and experience, we bring reliable and optimal performance of your combustion engine/ combined heat and power unit to the grid connection point according to the relevant technical guidelines.

Thus, you can use the extensive experience of our employees in dealing with the respective grid operators.
