Energy economic evaluation of decentralised CHP–systems for the energy supply of residential buildings

In line with the Bavarian Hydrogen Initiative the Research Institute for Energy Economy together with Lechwerke AG (LEW) has analysed different aspects of the decentralised energy supply. Based on the thermal and electric load curves as well as on the technological facts of each technique, the energy supply of residential buildings within a new building district was examined. In the main focus were fuel cell systems with a small power output for the house-based energy supply of residential buildings as well as bigger combined heat and power plants for the district heating.

A simulation of the grid provided interesting results about the effects on the low voltage electricity network (flow of energy, holding up of voltage, loss of energy within the electricity network, etc.). Beyond this the study contains information of the energy economic efficiency and the possible influence on costs and infrastructure of the electricity network.
