Nigeria’s power grid is 69.9% powered by thermal plants
  • Thermal energy dominates Nigeria’s grid, supplying 69.9% of total power.
  • Hydro plants contribute 30.1%, making them the country’s second major source.
  • The heavy reliance on thermal generation shows Nigeria’s grid is still largely fossil-fuel driven.
  • Hydro remains a crucial but secondary source, supporting overall supply stability.
Nigeria's DisCos recorded ₦360bn revenue gap after collecting ₦1.12tn from ₦1.49tn billed in H1 2025
  • DisCos billed approximately ₦1.49 trillion but collected only ₦1.12 trillion in H1 2025.
  • Ikeja and Eko DisCos generated the highest revenues, collecting ₦206.22 billion and ₦210.59 billion, respectively.
  • Revenue collection gaps remain significant, with Jos, Kaduna, and Yola posting the weakest collection performances.
  • The wide gap between billings and actual collections suggests persistent challenges in customer payment compliance, metering, and distribution efficiency.
Nigeria has installed 3.65 million electricity metres since 2019; Ikeja DisCo leads with 823,000, and Aba Power at the bottom with 56,000
  • Approximately 3.65 million metres have been installed nationwide across all frameworks since 2019.
  • Ikeja DisCo leads by a wide margin with 823,000 installations, over twice the volume of most other DisCos.
  • Kaduna, Yola, and Aba Power recorded the lowest metre installations, each below 100,000.
  • The disparities in installation totals reveal uneven progress in achieving nationwide metering coverage.
More than 8 in 10 electricity customers of Ikeja and Eko DisCos are now metered
  • Ikeja (84.6%) and Eko (83.3%) lead Nigeria’s metering performance, keeping unmetered customers below 17%.
  • Eight out of the twelve DisCos have metering rates below 60%, showing a wide sector imbalance.
  • The worst-performing DisCos — Yola, Jos, Kaduna, and Kano — have over 65% unmetered customers.
  • Regional disparities are sharp: Lagos and Abuja outperform northern and south-eastern DisCos by large margins.
Nigeria’s urban electrification has stalled below 90% for over three decades
  • Urban electricity access has remained between 80% and 89% since 1990, never crossing to 90%.
  • The inability to achieve universal access suggests that infrastructure expansion has struggled to keep pace with rapid urbanisation and population growth.
  • Periodic dips in access, such as in 2010 and 2015, point to challenges in maintaining consistent electricity supply rather than just extending connections.
  • Insufficient generation, outdated grids, and policy inefficiencies have constrained Nigeria’s ability to deliver reliable and universal electricity access even in its urban centres.
