Seeking a Possible Positive Energy Districts (PEDs) Location Choice from a Local Context: A Case Study in Tainan City, Taiwan

Abstract

COP28 emphasised the urgent need to accelerate energy transitions and decarbonisation. Cities, as major centres of energy consumption and carbon emissions, have become critical arenas for implementing these transitions. The EU and IEA have actively promoted Positive Energy Districts, shifting the focus from individual buildings to the district scale to enhance energy efficiency. This study focuses on socio-economic indicators and explores key variables influencing residential electricity consumption (REC). Using Tainan City as a case study, it combines rooftop PV generation potential and REC forecasting to evaluate the electricity self-sufficiency rate of each district. The results indicate that only “total household income” shows a significant positive correlation. Future research could utilise more granular data to improve assessment accuracy and provide evidence-based support for urban energy planning.
