This dataset represents potential expansion projects for existing mini-grids; the expansion projects were identified through a least-cost geospatial analysis undertaken over the period 2017-2018. Each project (defined by the unique “Project_Number”) includes electricity lines, poles, and building structures. Therefore, the dataset includes a combination of several feature types. The shapefiles are accompanied by the “Potential Mini-Grid expansion project cost” (included in the csv file). This csv file includes households/potential customers to be connected, line length by voltage level, project cost (in US$ million), and the cost per consumer for each unique mini-grid expansion project (again, defined by “Project_Number”).
