The increasing share of renewable energy sources such as photovoltaic or wind turbines have an impact to the grid stability – the grid is more difficult to stabilize. The cost for grid usage and measures to keep the grid running were growing in the past years. There are chances for companies to participate in the regulation markets and generate additional revenues by powering up or shutting down their facilities and supporting the stabilizing efforts of the grid operator. In particular, hybrid and bivalent facilities cover a high flexibility potential. Another matter of interest for companies is to reduce their energy costs by increasing their energy efficiency. However, energy flexibility from hybrid and bivalent systems and energy efficiency have an impact on each other and, therefore, on the energy costs. For companies there are many issues to consider if they want to participate in the flexibility market. One of them is to identify the right time to change the energy carrier and which factors need to be considered. The Institute of Energy Efficiency in Production EEP at the University of Stuttgart created a method for hybrid and bivalent facilities to provide a guideline for companies. It indicates, which parameters to consider, if companies want to change the energy carrier of their processes and how to determine the right time to change, depending on energy efficiency, feasibility and the revenues of the energy market.
