What is the energy access problem in Mali?
Mali faces a critical energy access challenge. The national power access rate was 50% in 2019 (compared to 36.11% in 2015). The problem is particularly acute in rural areas with 21.12% access rate in 2019 (compared to 15.75% in 2015).
Why is energy du Mali struggling with load shedding?
Power generation is limited (Annex A.17), forcing Energie du Mali (EDM, the power utility) to have recourse to frequent load shedding. EDM's difficulties stem from the discrepancy between the average price (CFAF96 per KWh) and the power production cost (CFAF130 per kWh) in 2019.
