Abstract: The integration and efficient utilization of fluctuating renewable energies are crucial for the decarbonization of energy systems. The flexibilization of industrial processes can play a key role in achieving this objective. Previous research mainly focusses on price-based demand side management. However, recent research shows that electricity prices and respective GHG emissions do not always correlate. In this study, we carry out emission-based load shifting of an electrified steam process from the pet food industry for the German electricity in 2017 to 2019. The steam system is equipped with a 130 m3 steam storage tank to enable load shifting. We analyse the impact on annual GHG emissions utilizing quarter-hourly and hourly EFs and compare the results to price-based load shifting. Further, we conduct a multi-level sensitivity analysis: We perform the analysis for each of Germany’s four transmission zones in order to analyse the effects on different electricity mix compositions. Further, we investigate steam storage size variations (65, 195, 260 and 300 m3) and carry out Monte Carlo Simulations. The Monte Carlo Simulations serve to represent real-world conditions by randomizing model input according to probability distributions.
