Electricity Generation
electricity · monthly · Unit: GWh · 26 records · Generated 25 September 2026
What this is: Total electricity generated at grid-connected power plants in Nigeria each month, covering thermal (gas), hydroelectric, and renewable sources. Measured in gigawatt-hours (GWh) at the plant busbar.
Why it matters: Generation capacity is the ceiling for Nigeria's electricity supply. The gap between installed capacity (MW) and actual generation (GWh) reveals how much of the system is idle — a key indicator of infrastructure and fuel supply health.
