Energy efficiency measures in the industrial sector contributed to the decarbonisation over the last years. For a successful transition towards an energy system with high shares of variable energy sources it is assumed that flexibility on the demand side will increase in value /FFE-14 16/. This paper deals with the conflict and compliance potentials of these two goals.

The analysis is conducted from two directions. At first, the impact on the energy consumption of running industrial processes is calculated for six specific applications. For this approach the change in the weighted overall efficiency level is chosen as evaluation criteria. Secondly, the effects of energy efficiency measures on the flexibility potential are discussed. Installed overcapacities are on the one hand one of the key causes for flexibly running processes and on the other hand the reason for energy inefficiency. The different roots of overcapacities are depicted and the relating impacts of using these capacities for demand side management are assessed. The second part of the analysis shows that the influence of energy efficiency measures on flexibility potential is a slight decrease in positive demand response potential and an increase of the negative demand response potential.
