摘要：Limited data on global power infrastructure makes it difficult to respond to challenges in electricity access and climate change.Although high-voltage data on transmission networks are often available, medium- and low-voltage data are often non-existent or unavailable.This presents a challenge for practitioners working on the electricity access agenda, power sector resilience or climate change adaptation.Using state-of-the-art algorithms in geospatial data analysis, we create a first composite map of the global power system with an open license.We find that 97% of the global population lives within 10-km of a MV line, but with large variations between regions and income levels.We show an accuracy of 75% across our validation set of 14 countries, and we demonstrate the value of these data at both a national and regional level.The results from this study pave the way for improved efforts in electricity modelling and planning and are an important step in tackling the Sustainable Development Goals.
