MINIGRID INVESTMENT REPORT

The report examines the Nigerian minigrid sector, highlighting a potential annual revenue opportunity of ₦2.8 trillion (US$8 billion). Based on audits of ten commercial projects, it identifies best practices such as optimal site selection, community engagement, and appliance financing. While the regulatory environment is generally supportive, the report identifies barriers including high hardware costs, limited affordable finance, and inconsistent customs processes, proposing a series of stakeholder-specific actions to accelerate market growth.

• Nigeria's underdeveloped minigrid market represents a significant economic opportunity, with potential annual revenues estimated at ₦2.8 trillion (US$8 billion). Scaling the market to 10,000 sites of 100 kW by 2023 could provide electricity to 14% of the population and create a ₦7 trillion (US$20 billion) investment opportunity.
• Audits of ten commercial minigrids show that costs are becoming competitive with diesel and petrol generators, which typically cost over ₦250 (US$0.70) per kilowatt-hour. Audited minigrid tariffs range from ₦120 to ₦300 per kWh, with a median of ₦200 per kWh.
• Successful commercial minigrids typically employ an owner-operator business model with a financing mix of approximately 70% debt and 30% equity, often supplemented by grants. These projects report returns of 15%–20%.
• Key operational best practices for minigrid success include selecting densely populated sites with high economic activity, engaging communities early to ensure buy-in, and implementing appliance financing to stimulate daytime demand and balance load profiles.
• The Nigerian Electricity Regulatory Commission’s (NERC) 2017 Mini Grid Regulation is a critical enabler, particularly for systems under 100 kW which do not require a permit, and by protecting the right to set cost-reflective tariffs.
• Significant barriers to scaling the market include high upfront hardware costs, prohibitive Environmental and Social Impact Assessment (ESIA) costs for projects over 100 kW, and inconsistent implementation of import duty exemptions.
• There is a critical need for more affordable project finance, as local commercial interest rates are often 20% or higher, and many developers struggle to produce bankable documentation for investors.
• The adoption of standardised, modular minigrid systems could significantly reduce costs, potentially cutting engineering time by one-third, installation costs by 80%, and total service costs by up to 20%.
