Evidence overview
Over 560 million
People in sub-Saharan Africa lacked electricity access in the 2024 baseline reported by Tracking SDG7 2026.
World Bank and SDG7 custodian agencies · Energy Progress Report release, 2026 ↗Data scope: Sub-Saharan Africa; access estimates published in June 2026. An electricity connection does not establish reliable or affordable supply.
What the evidence tells us
The SDG7 custodian agencies report that the remaining electricity-access gap is heavily concentrated in sub-Saharan Africa. Their report also identifies a major clean-cooking deficit. These access measures establish the scale of the problem, while facility-level records are needed to understand interruptions and usable power.
Read the underlying source ↗Axum’s research and commercialisation agenda
Axum’s proposed work focuses on dependable electricity for productive activity. Invention discovery should begin with measured operating failures and the cost of maintaining equipment. A product must improve delivered service under local conditions before it can justify commercial rollout.
These are proposed research directions. Patentability and commercial viability remain to be established for each invention.
Research directions
Grid disturbance detection →
A defined distribution or transmission network
Which measurements give operators actionable warning of a disturbance?
