Additional socio-economic data available for entire Nigeria are number of schools, health facilities and telecom towers currently relying on diesel generators.
Exclusion Criteria:
• Exclusion of sites with distance to grid <5km• Exclusion of sites with population < 1,000• Exclusion of sites that fall within protected areas, national parks and other
ecologically sensitive zones
Prioritization Criteria:
• Ranking of sites based on population, density, schools, health facilities, distance to grid, anchor customers.

Impact of Geospatial and Digital Tools
• Significant reduction in pre-investment costs associated with mini grid development
• Unprecedented scale possible because of the low costs involved
• Swifter speed compared to traditional approaches that require the deployment of multi-disciplinary teams at considerable expense
• Experience from Nigeria suggests mini grid portfolio planning already feasible at a cost of approximately $2300 per site, with scope for further cost reduction
