Analysis of Energy Use and Sector Coupling Opportunities in an Energy Community Using an Energy Cost Centre‐Based Model

The integration of energy sectors and the optimisation of resource use are fundamental elements of sustainable development. This study presents a model for analysing energy use based on the structure of Energy Cost Centres (ECCs). The model facilitates a systematic identification and optimisation of energy flows in industrial and urban environments. The developed methodology was tested on a case study of an energy-intensive industry, where we analysed the potential utilisation of renewable energy sources, hydrogen production, electricity storage, and the use of excess heat for the local community. The results indicate that the systematic application of the model could achieve total electricity savings of 9,598 MWh, alongside 4,116,850 Nm³ of natural gas savings through excess heat utilisation. These measures collectively contribute to an annual CO₂ emissions reduction of 10,984 tonnes. The approach enhances the integration of sustainable energy solutions, strengthens stakeholder collaboration, and increases the economic viability of projects. Moreover, the model can be adapted for use in other industrial and urban settings. Despite potential barriers such as data availability and initial implementation costs, the results confirm the approach´s value in the strategic planning of sustainable energy systems.
