Combined heat and power

Add to Bookmarks

A solution with high overall energy utilisation: The principle of combined heat and power makes combined heat and power plants (CHP) established decentralized generators of electricity and heating. With this method, ENGIE Deutschland offers you an on-site supply of electricity and heating that lowers primary energy consumption compared with the separate generation of power and heat. On request, the CHP unit can be operated with biogas.

Bridge to supply from renewables

CHP can support the transition towards increased use of renewable energy sources. CHP units are characterized by high levels of efficiency and offer favorable on-site generation compared to electricity purchased from the grid. If you operate your CHP module with biogas, you can already make the leap into electricity and heat generation using biogas. Until your generation is completely converted, ENGIE can provide certificates and environmental attributes according to the applicable schemes and accounting frameworks.

CHP: High overall efficiency

CHP modules can achieve total utilization rates of up to 90 percent and save up to 35 percent of the primary energy demand and corresponding CO₂ emissions compared to conventional large power plants. The joint and efficient generation of electricity and heat is appealing wherever you need to serve a continuous demand for energy, for example in industrial processes, in hospitals, in hotels and in interconnected residential properties. In municipal energy supply and district heating systems, CHP modules can also be used as a first step towards a low-carbon supply.

Application areas for CHP

Real estate: Modern replacement for outdated heating systems

Always consider the installation of a CHP unit when performing an energetic refurbishment. This way you can significantly improve the primary energy factor. If your property (or several in an energy network) has a heating need of about 400 to 500 kWth (kilowatts thermal) per year, it may be worth evaluating for a combined heat and power plant with a capacity of about 50 kWel (kilowatts electrical). Such a property could be, for example, a larger residential property or a training center. The electricity generated in parallel can be consumed directly on site by the tenants or owner companies (common-area electricity).

Industry and commerce: Decentralized energy supply for greater independence

If your company wishes to embark on the path to a more resource-efficient and economically viable energy supply, we at ENGIE Deutschland will support you in the process. Our energy specialists design and build the CHP to meet your needs and handle its operation. ENGIE also defined operational risks over the entire duration of the contract if desired. By adopting a heat-oriented mode of operation, you as a large-scale consumer can supplant the purchase of electricity from the grid. At the same time, a power-oriented operation to reduce power peaks can be a value-adding approach for you. Our engineers optimize the interaction of all components to reduce energy costs and achieve high efficiency. This supports independent generation of electricity and heating for your production and commercial areas – and can help reduce energy costs over the long term.

Hotels or hospitals: Long-term energy supply concepts

When high energy demand and high competitive pressure are combined, things become critical – a situation that many managers in hospitals or hotels know all too well. How do you achieve greater energy efficiency? How can organizations reduce greenhouse-gas emissions while maintaining a reliable energy supply? ENGIE Deutschland offers a reliable supply of electricity and heat from efficient CHP plants as part of contracting partnerships. As an operator of a CHP plant, we are able to generate and guarantee additional cost advantages using our own technical and energy expertise. If desired, your CHP unit can run on biogas as part of the contracting or operational management model.

Public utilities and utilities: Heat generation with reduced CO₂ emissions

With a view to the energy future, smaller, decentralized structures are of enormous importance in order to ensure the basic load supply of the networks when nuclear and coal power plants are shut down. ENGIE Deutschland has demonstrated in two pioneering projects in Gera and Saarbrücken how we reduce CO₂ emissions by converting to CHP or optimizing outdated CHP plants and ensuring a more efficient supply of district heating. Highly efficient CHP systems generate district heating for local heat supply and electricity for feeding into the grid. As part of decarbonization pathways, natural gas CHP plants are important bridges: Thanks to the efficiency of the cogeneration plants of up to 90 percent, they emit approximately 60 percent less CO₂ compared to the power generation via gas turbines. The coupling of many small CHP plants to a virtual power plant makes can contribute to supporting base-load supply.
