Abstract

Cogeneration is a promising technology in the energy transition amongst other things in view of its energy efficiency and its broad applicability in the household, tertiary and industry sectors. For the promotion of cogeneration technologies, support schemes are in place in German energy policy. Amongst other things the Combined Heat and Power (CHP) Act serves as the main instrument for the promotion since 2002. In the new version of the CHP Act of 2016 the German Federal Government strives towards a more market-oriented design resulting in significant amendments featuring inter alia a highly case-dependent tariff design with modified levels and durations of remuneration. It is therefore the aim of the present study to assess these modifications with respect to technical, economic and ecological aspects in a model-based approach by means of selected use cases at different levels of spatial aggregation for residential buildings. Results point to an economic advantageousness for cases of the medium energy consumption level (streets and blocks of houses) under the new regime as well as the reversal of this attractiveness for objects of high consumption (neighbourhoods, districts). Particularly, CHP plants tend be dimensioned comparatively smaller with a greater number of full-load hours under the new regime. Furthermore, implications with regard to technical and ecological aspects are shown in this contribution
