Summary

• What is new: This research introduces an innovative method that combines multi-criteria optimization for building-level decisions with grid expansion analysis to understand their reciprocal effects on decentralized energy supply systems aimed at decarbonizing the building sector.
• Why this is important: The need to reduce greenhouse gas emissions in the building sector by 2045, considering the challenges of integrating renewable energy sources and low-CO2 heat generators without overburdening the electrical grid infrastructure.
• What the research proposes: A holistic analysis method that merges building-level expansion and operation decision-making with grid expansion planning to assess the impact of increased self-generation and renewable energy adoption on grid stability and charges.
• Results: The study provides insights into how grid charges and expansion influence the decision-making of grid users towards adopting renewable energy solutions, thereby suggesting a pathway to decentralized energy systems without overloading the grid.
