A mini-grid is an electricity supply system with its own generation capacity that supplies power to more than one customer within a defined geographical area. It can operate independently or in coordination with an existing distribution network.

Under the Mini-Grid Regulations 2026, mini-grids are classified as:

• Isolated Mini-Grids – operate independently of a Distribution Licensee’s network, typically serving unserved areas, with installed capacity up to 5MW per site.
• Interconnected Mini-Grids – connected to and operated in coordination with a Distribution Licensee’s network, typically in underserved areas, with installed capacity up to 10MW per site.

Mini-grids play a critical role in expanding electricity access, particularly in unserved and underserved communities across Nigeria.

The Mini-Grid Regulations 2026 provide a comprehensive and modern framework to promote investment, ensure consumer protection, and support rapid electrification.

Key Improvements in the 2026 Regulations:

1. Expanded Capacity and Scope

• Isolated mini-grids: up to 5MW
• Interconnected mini-grids: up to 10MW
• Enables larger, more commercially viable projects.

2. Improved Investment Protection

• Developers benefit from site exclusivity rights during project development.
• Clear and structured compensation framework in the event of grid arrival.
• Compensation now reflects:
  • Depreciated asset value
  • Replacement cost considerations
  • Revenue protection (depending on project age)

3. Clearer Grid Arrival & Transition Framework

• Distribution Companies must provide 12 months’ notice before grid extension.
• Multiple transition options including:
  • Conversion to interconnected mini-grid
  • Asset transfer
  • Continued operation under agreement
  • Orderly exit

4. Streamlined Permitting & Registration

• Projects ≤100kW: simple registration
• Larger systems: permit required
• Defined timelines (up to 30 business days) for approvals
• Introduction of portfolio applications for multiple sites

5. Enhanced Interconnection Framework

• Mandatory Tripartite Agreement (Developer, DisCo, Community)
• Introduction of Hosting Capacity Information (HCI) for planning
• Simplified interconnection pathways for small solar projects
• System Impact Study (SIS) required only where necessary

6. Cost-Reflective Tariffs with Safeguards

• Tariffs determined using an approved Mini-Grid Tariff Model
• Allows cost recovery while protecting consumers
• Clearly defined loss thresholds and performance benchmarks

7. Strong Consumer Protection Measures

• Mandatory customer service charters
• Defined complaint resolution procedures
• Standards for billing, metering, and service quality

8. Environmental and Safety Compliance

• Mandatory compliance with environmental laws
• Simplified pathway (ESMP) for solar mini-grids
• Full ESIA only where required (e.g., hydro or sensitive areas)
