Energy Data Analytics Lab: Energy Infrastructure Map of the World through Satellite Data (2018-2019)
Over 15% of humanity has no access to electricity, and far more have unreliable access that precludes most productive energy uses that are beneficial for improving economic prosperity, health and education. Decision-makers require information to determine the optimal strategies for deploying energy resources to decide where to prioritize development and whether that development should be through grid expansion, microgrids or distributed generation. However, two critical data sources for such planning—who has access to electricity and the location of electric infrastructure—are often unavailable or overly time-consuming to collect and maintain.
To address these needs, this Bass Connections project set a goal of working toward creating an energy infrastructure map of the world using satellite imagery. The project team employed state-of-the-art machine learning tools in order to detect critical energy infrastructure in satellite imagery including power distribution lines and off-grid distributed energy generation sources such as solar photovoltaics. Team members approached their analysis from an integrated systems perspective. Instead of modeling individual components of the system independently (generation, distribution, consumption), the team employed techniques that consider these components as part of an integrated whole, comprising a national grid and perhaps local off-grid microgrids. This was the first step toward a functional energy infrastructure map of the world.
Team members used both publicly available data from the U.S. as well as purchased data covering underserved parts of south and central Asia. This work, combined with the research from previous Bass Connections and Data+ projects, provides a toolset that will enable the remote assessment of generation, transmission, distribution, end-use and access to electricity. The team plans to unify these components toward a vision of a methodology for automatically mapping and assessing energy systems in any place on Earth.
