In the context of tightening climate policies, industrial clusters and large metallurgical enterprises must revise their carbon emissions targets and develop transition strategies toward carbon neutrality. This study demon- strates that reducing the carbon footprint associated with electricity production and consumption in the in- dustrial sector can be feasible utilizing the real-time car- bon intensity monitoring of on-site power plants, avail- able distributed renewables, and green electricity sup- plied by the external grid. We evaluated this strategy using a co-simulation approach applied to the electrical grid of an industrial area with steel processing enter- prises in Bremen.The results indicate that, given Ger- many’s gradual de-carbonization of electricity produc- tion, a strategy focused on adjusting on-site power gen- eration from carbon-intensive sources such as natural gas and metallurgical waste gases can be effective in meeting stringent short-term carbon footprint targets during the energy transition. This work contributes to the open data and modeling efforts in the energy research community, ensuring reproducibility and en- abling further independent research.
