The expansion of Combined Heat and Power (CHP) is an important part of energy and climate protection policies both at the national and the federal state level. The State Government of Baden-Wuerttemberg has therefore drawn up a state CHP concept based on a study conducted by ZSW in conjunction with the German Aerospace Centre (DLR) and the energy scientist Dr Joachim Nitsch. In the context of the study, the authors describe the current status of CHP growth, analyse the current framework conditions for combined heat and power and develop a total of 22 proposals for supporting the expansion of CHP systems in Baden-Wuerttemberg. Among others, the measures include increased use of CHP in state properties, enhanced information and consulting services, development of state subsidy programmes and introduction of pilot projects. However, according to the 140-page paper, the success of any state concept depends on the appropriate design of the political framework conditions at the national level.
