# Deep Research Log: International Databases for Nigeria Grid Electricity Generation

Generated: 2026-06-19T08:32+00:00 UTC

## Scope

Search international databases for annual Nigerian electricity generation (GWh) by fuel type and by plant, with emphasis on hydro plants (Kainji, Jebba, Shiroro) for 2020-2024.

## Summary of findings

- National fuel-level generation (GWh/TWh) was found from **Ember**, **Our World in Data**, **IRENA**, **EIA**, **IEA**, and **World Bank** (shares only).
- The UNSD *Electricity Profiles* PDFs provide country-level production tables (including hydro vs thermal) for 2018-2023.
- **Plant-level generation for Kainji, Jebba and Shiroro is not available** in any of the international sources searched. This remains a gap and will need to be filled from Nigerian sources (NERC reports, TCN operational data, WAPP/OMVS assessments).

## Remaining gaps

1. **Plant-level hydro generation** — No international database provides annual GWh for Kainji, Jebba or Shiroro individually. search focused on databases that publish national aggregates.
2. **2024 data** — IRENA 2025 H2 release stops at 2023; World Bank/Ember/OWID may have 2024 but absolute totals depend on source vintage.
3. **EIA CSV time-series** — EIA international bulk/API access was not reachable without an API key; the EIA Nigeria analysis PDF provides a single-year snapshot.

## Next steps

- Extract Nigeria generation-by-fuel tables from the downloaded CSVs and cross-check totals.
- Continue searching Nigerian/WAPP sources for plant-level hydro output (Kainji/Jebba/Shiroro).
