OBA/Approaches: Summary of the Rural Electrification Hybrid System Project in Mali

Core Content

The Output-Based Aid (OBA) project in Mali, known as the Rural Electrification Hybrid System Project, is an innovative initiative aimed at expanding access to modern energy services in rural, off-grid areas. It is the first large-scale OBA project in the energy sector in Mali and is supported by the International Development Association (IDA) and the Climate Investment Funds/Scaling Up Renewable Energy in Low Income Countries Program (SREP). The project focuses on improving the affordability and accessibility of electricity for poor households by combining mini-grid and Solar Home Systems (SHS) solutions.

Main Objectives

Increase access to electricity in rural Mali, where over 80% of the population resides but only 15% are electrified.
Support the development of off-grid solutions through a least-cost approach.
Ensure financial sustainability for private operators and affordability for rural poor.
Promote renewable energy generation and energy efficiency.

Key Components of the Project

1. OBA Subsidies

The project provides subsidies to private operators to implement the least-cost electrification option for households.
Mini-grid densification and internal wiring:
- Unit cost: $282 (no pole) and $959 (one pole).
- Subsidy: $227 (no pole) and $844 (one pole).
Solar Home Systems (SHS):
- Unit cost: $717 (with wiring).
- Subsidy: $586.
Internal wiring package includes three Compact Fluorescent Lamps (CFLs) to promote efficient electricity use.

2. Recovery of Private Operator Contributions

Operators contribute to the cost of connections through cost-reflective tariffs and fee-for-service.
For mini-grids:
- No-pole connection: $40.
- One-pole connection: $100.
For SHSs: $116.
These contributions are based on households' willingness-to-pay, which is estimated at $15 per connection.

3. Verification and Disbursement

A second component provides $300,000 in technical assistance to AMADER for hiring independent verification agents (IVAs).
Subsidies are disbursed in two phases:
- 80% upon completion and verification of the connection.
- 20% after three months of operation and 80% of beneficiaries paying for electricity.

Implementation and Financial Arrangements

The project is managed by AMADER, the Malian Agency for Development of Rural Electricity.
Private operators are selected based on:
- Potential demand and economic growth.
- Source of up-front capital.
- Proven past performance.
- Technical, economic, and financial viability.
- Clear outputs and balanced geographical representation.
Pre-financing is required from operators, who must fund the connections and internal wiring before receiving subsidies.
Sources of pre-financing include revenues from energy activities and commercial loans.

Lessons Learned

Performance-based incentives improve access, as seen in the HEURA project. The OBA model shifts risk to operators, ensuring better performance.
Institutional support and capacity building are essential in conflict-affected or fragile contexts. The project includes strong support for AMADER and service providers.
Clear communication is vital in remote areas. AMADER maintains ongoing dialogue with operators and residents to clarify responsibilities and expectations.
Market demand influences project design. The SHS component was adjusted to a range of 50-135 Wp based on market needs, while subsidy levels remained constant.

Conclusion and Sustainability

The private sector-driven off-grid approach is central to Mali's rural electrification strategy due to the challenges of national grid expansion in dispersed, low-income areas.
The project promotes public-private partnerships, renewable energy, and energy efficiency.
Hybridization of systems is crucial for financial stability and investment incentives.
The OBA model supports sustainable access to electricity for the poor, especially when integrated with clean energy initiatives and local partnerships.
