Nigeria

Overview​

Nigeria’s electricity market is transitioning from a centralized federal monopoly toward a more decentralized, state-led framework following the Electricity Act 2023. Grid reliability remains a key constraint, with repeated system collapses reported in recent years, and a persistent sector liquidity crisis impacting generators and distribution companies.

The generation mix is dominated by natural gas, with large hydropower as the primary low‑carbon source. Modern renewables (utility solar/wind) are growing from a low base.

SSS Relevance⭐ Low–Medium
Market TypeTransitioning / partially deregulated (state-led under Electricity Act 2023)
Dominant generationGas-thermal + large hydro
EAC/REC infrastructurePrimarily I‑REC (no national mandatory REC registry)

Market Structure​

Nigeria’s sector reform under the Electricity Act 2023 enables states to regulate generation, transmission, and distribution within their borders (in addition to the national framework).

Key features:

  • NERC remains the national regulator; multiple states have begun establishing or receiving delegated regulatory authority.
  • Transmission infrastructure is operated through the legacy Transmission Company of Nigeria (TCN) framework, with ongoing market/operator restructuring (including the creation of the Nigerian Independent System Operator (NISO) in recent reforms).
  • Large C&I customers may access limited competitive procurement via Eligible Customer rules (direct purchases from GenCos), while broader retail competition is still evolving.

Clean Energy Policy​

Nigeria’s clean energy policy is anchored by a net‑zero by 2060 target (Energy Transition Plan + Climate Change Act 2021).

Commonly cited targets include:

  • “30:30:30” vision (30 GW capacity by 2030, 30% renewables)
  • Use of gas as a transition fuel while scaling solar, mini‑grids, and decentralized renewables

Implementation mechanisms are described more as renewable purchase / generation obligations and programmatic measures than a single, unified RPS law.

Utility Landscape​

Distribution is handled by 11 privatized distribution companies (DisCos) (with varying government minority stakes reported in secondary sources). Transmission remains state-owned/controlled.

Large market participants frequently cited:

  • DisCos: IBEDC, Ikeja Electric, Eko DisCo, Abuja DisCo, Benin DisCo
  • GenCos: Egbin Power (~1.3 GW), Transcorp (Ughelli ~972 MW), Geregu, and Mainstream Energy Solutions (hydro operator of Kainji + Jebba)

SSS-Eligible Resources​

Hydropower (primary SSS-relevant resource)​

Large hydro is Nigeria’s main low‑carbon generation source and the most plausible “standard supply” clean resource for SSS-style accounting (subject to local attribute claims and any certificate retirement).

Major facilities:

  • Kainji — ~760 MW
  • Jebba — ~578 MW
  • Shiroro — ~600 MW
  • Zungeru — ~700 MW (commissioned 2023)

Nuclear​

Nigeria has no commercial nuclear generation. The only reactor is NIRR‑1 (research reactor), which does not contribute to grid electricity supply.

Solar / wind (emerging)​

Utility-scale solar and wind exist but remain a small share of grid supply relative to gas + hydro.

SSS classification (preliminary)​

Resource TypeSSS EligibilityNotes
Large legacy hydro delivered on-grid⚠️ Likely / case-by-caseDepends on whether attributes are claimed/retired via I‑RECs or other instruments
Gas generation❌ Not SSSFossil
Utility solar/wind⚠️ Gray areaOften paired with I‑RECs; must avoid double counting
NuclearN/ANo commercial nuclear

EAC/REC Registry Infrastructure​

Nigeria does not appear to have a government-mandated national REC registry for corporate claims. Attribute tracking is commonly done through:

  • I‑REC Standard (I‑TRACK Foundation), via certified registrars/market facilitators.

Emissions Factors & Data Sources​

For Scope 2 reporting, emissions factors are generally sourced from international references (e.g., IEA / harmonized grid factors), not U.S.-specific datasets such as eGRID.

A commonly cited location-based grid factor in secondary sources is approximately 0.00052579 MTCO2e/kWh (~526 gCO2e/kWh) (Harmonized IFI default grid factors). Note: Nigeria’s reported grid intensity varies widely by dataset and assumptions (and many users have substantial self-generation that should be treated as Scope 1).

Confidence Assessment​

High confidence:

  • Electricity Act 2023 enabling state-level market regulation
  • Gas + hydro dominance; lack of commercial nuclear
  • I‑REC as the main EAC pathway for Nigeria in international reporting contexts

Needs verification / watchouts:

  • Whether (and how) large hydro attributes are claimed domestically vs. left “unclaimed” for residual mix purposes
  • Official Nigerian grid emission factors suitable for Scope 2 inventories (and time period alignment)
  • Data quality gaps due to grid instability and behind-the-meter diesel generation
