CHP plants
Combined heat and power plants (CHP plants) produce electricity and use the waste heat for heating purposes.
In addition to investment funding, the basic element of the model is the obligation to purchase and pay for the electricity produced by the grid operator.
Operators of CHP plants thus generate their own electricity. This self-produced electricity can be consumed and/or fed into the public grid. In the self-consumption model, metering is carried out using a meter that can simultaneously record consumption and feed-in. Self-consumed electricity is not recorded by the meter. It is therefore important with this model that consumption takes place at the same time as production wherever possible. Organizational measures (controllable relevant consumers such as heat pumps, heat pump boilers, cooling systems, etc.) can significantly increase the degree of self-consumption and thus the amount of electricity not purchased.
Funding application
The funding application and the power of attorney must always be submitted in full and on paper, including all enclosures. Submissions by e-mail are not sufficient. The content of applications will only be processed once the application documents have been received in full.
The subsidies for CHP systems are made up of 3 elements:
- Investment contribution for electrical output: CHF 400 per kWel for the installed electrical output for systems from 1 to a maximum of 250 kWel. Please also note that most municipalities provide this contribution up to a maximum limit of CHF 10,000. This means that for systems up to 25 kWp, CHF 400 per kWp (country CHF 400 and municipality CHF 400) is possible as a one-off subsidy.
- Electricity remuneration: Fixed feed-in remuneration (state parliament resolution 30.09.2021) for systems that are connected to the grid by 31.12.2022 at the latest or according to market-oriented price (the electricity can be consumed by the customer as far as possible.)
- Domestic technology system: The heated energy reference area and the fuel are decisive for the system as a heat generator. You can use the "Calculation tool for subsidy amount" to determine your individual subsidy entitlement. The type of building technology system and the size of the building are decisive for the subsidy.
- Only new, state-of-the-art systems and system components and appliances are to be used.
-
The measuring points prescribed by Art. 9 EEV must be installed to monitor the efficiency of the system and the figures must be reported annually to the energy office and in the production certificate of the LKW.
-
The heating and hot water systems, including all distribution pipes, must be fitted with continuous thermal insulation. The minimum insulation thicknesses can be found in the following table:

Building services installations are not eligible for subsidies if they are used as supplementary heating to a sufficient (monovalent) heating system.
Start of Construction – Forfeiture of Entitlement The entitlement to receive funding grants lapses if the measures are commenced before a legally binding approval of the funding has been issued.
Project Author / Planner Funding grants are only paid out if competent planning and professional implementation of the measures are ensured.
Time Limit In accordance with Art. 25 of the Energy Act (EEG), the funding approval is subject to a time limit. The measure must be started within one year of the decision on the granting of funding and completed within two years.
Mandatory Other Provisions The measure is not subsidized if it is mandatory due to other legal regulations in accordance with Art. 4. para. 2a) EEG (e.g. development plan, air conditioning, swimming pool heating, conversion, etc.).
Repeat Funding Funding grants are awarded only once per measure; repeat funding of the same measure is only possible after a period of 20 years has elapsed.
For the assessment of any potential funding after 20 years, the original funding approval date is decisive.
