Questions and answers

Here you can find answers to FAQs on plants under the Combined Heat and Power Act.

What is a Combined Heat and Power plant (CHP plant)?

In a CHP plant, mechanical energy (power) and thermal energy (heat) are generated using a combustion engine. The mechanical energy is transformed into electrical energy using a generator. The simultaneous generation and use of power and heat (combination) achieves greater effectiveness compared to separate generation.

What is a Thermal Power Station?

In a CHP plant, mechanical energy (power) and thermal energy (heat) are generated using a combustion engine. The mechanical energy is transformed into electrical energy using a generator. The simultaneous generation and use of power and heat (combination) achieves greater effectiveness compared to separate generation.

What support programmes exist for CHP plants?

There are various incentives, depending on the primary energy sources. Your grid operator is responsible for paying out under the Combined Heat and Power Act or the Renewable Energies Act.

We will be happy to advise you in this regard. You can find further information on CHP plants, as per the Renewable Energies Act, in our information on the Renewable Energies Act on the Renewable Energies page.

How long does it take to process a connection application from a generation plant?

For plants up to 30 kW, five working days should generally be allowed for a response. During this time, the customer will receive an offer and/or confirmation of receipt of their query. This relies on all the requisite documents having been submitted.

Who should make the application to the grid operator to connect a generation plant?

The application can be made by the operator of the plant, but is generally made by its constructor.

Is an existing grid connection always used as a feed-in point?

There is a routine check to determine whether the plant can be incorporated into the relevant grid using an existing connection. If the network compatibility check shows that the energy can be fed in at the existing connection, the plant operator will be notified. There are also checks to determine the conditions for accepting the energy into the distribution grid before a corresponding offer is made.

When will I receive payment?

After the CHP plant has begun to operate in line with the CHP Plant Act, the feeder will submit the following documents to the grid operator:

  • Operation initiation protocol signed by the plant's operator and constructor.
  • Customer information leaflet (containing the plant operator's details)
  • Proof of registration with the Federal Office of Economics and Export Control (Bundesamt für Wirtschaft und Ausfuhrkontrolle (BAFA)).

After all documents have been received, a feed-in agreement is drawn up and sent to the operator. After the agreement has been signed, payments will commence.

How much will I be paid?

Remuneration for the CHP plant under the CHP Plant Act is determined according to when operations are launched and plant performance. The remuneration terms in the CHP Plant Act valid at the time of the initiation of operations are used in the calculation.

Will I incur charges for meter replacement etc.?

Stromnetz Berlin GmbH covers the cost of meter replacement. The plant operator covers the cost of any electrical installation work required. Furthermore, the operator bears the cost of measurement, running the measurement point and calculation. You can find the prices on our price sheet.
