Abstract
Abstract A power supply system for generating at least one of heat and electricity which includes a number of statically and functionally independent units adapted to generate at least one of heat and electricity which enable a maximum utilization of primary energy. For decentralized power supply over short and low loss supply lines the individual units are constructed as stackable modules. By exchanging or adding one or more modules, it is possible to adapt the flexibility of the power supply system to changes in demand for the energy thereby providing a practical approach to the utilization of waste heat for energy conservation purposes.
