An essential component of all strategies for a climate-friendly transition of the energy system is combined heat and power (CHP). Also the federal government has set a target of achieving a 25% share of CHP in power generation by 2020. Reasons for the key role of CHP in a sustainable energy system of the future is the high efficiency of combined heat and power generation and its great flexibility in terms of system size and operating conditions. Moreover, CHP as flexible power production units will play an important role for the integration of intermittent renewable electricity generation into the power sector. The necessary bonding of CHP to the place of heat consumption also guarantees a locally and regionally highly differentiated structure of the energy supply in which numerous actors can participate.
For these reasons, CHP plays a key role also in the integrated energy and climate protection concept (Integriertes Energie- und Klimaschutzkonzept, IEKK) of the State Government of Baden-Württemberg. A key measure (M 17) of the IEKK is the state concept combined heat and power (“Landeskonzept Kraft-Wärme-Kopplung”). This concept should include instruments for the expansion of CHP plants as well as of the necessary district heating networks in Baden-Württemberg, show expansion potentials, analyze the role of CHP in the heat and power markets of the future and make proposals for removing market barriers.
ZSW and DLR in cooperation with Dr. J. Nitsch have been commissioned to create such a policy-oriented CHP concept. Within the project current boundary conditions for CHP are analyzed and actor structures as well as existing barriers are examined at first. The following works address the role of CHP in future power and heat markets. Finally, policy measures to expand CHP in Baden-Württemberg are derived, prioritized and temporally structured.
