Unlocking long-term scale: Rethinking RBF for sustainable mini-grids

This white paper by the ARE Financier Circle examines how Results-Based Financing (RBF) for mini-grids in sub-Saharan Africa can be optimized to better mobilize private commercial capital. It argues that current RBF designs often prioritize short-term connection numbers over long-term business viability, creating 'cliff-edge risks' and administrative barriers that deter investors. The paper proposes a four-pillar approach focusing on aligning impact metrics with commercial sustainability, adjusting disbursement schedules to support capital raises, introducing lifecycle risk mitigation instruments, and fostering ecosystem-wide collaboration.

• Current RBF programs often create perverse incentives by focusing primarily on the number of new connections rather than the quality or long-term viability of those connections. This leads developers to prioritize simple household connections over more complex but commercially valuable productive-use connections, which are essential for increasing average revenue per user (ARPU).
• The 'myopia' of existing RBF programs, characterized by short and rigid timelines, creates 'cliff-edge risks' for developers. This lack of continuity after subsidies end hinders the ability of developers to plan for sustained growth or secure long-term equity and debt capital.
• Disbursement models in RBF programs often create cash flow constraints because funds are typically released only after project commissioning. The paper recommends a multi-stage structure including upfront CAPEX support, performance-based rewards, and post-commissioning support.
• Administrative complexity and a 'chicken and egg' problem regarding funding assurance and investment commitments delay project timelines. Due diligence processes for RBF programs can take up to 18 months per investor, increasing transaction costs and deterring participation.
• To ensure long-term sustainability, RBF must be complemented by instruments that mitigate macroeconomic and operational risks, such as foreign exchange (FX) volatility, inflation, and lower-than-expected energy demand. Suggested tools include FX guarantees, minimum revenue guarantees, and blended finance structures.
• There is a significant funding gap in early-stage project development for high-risk, pre-revenue activities such as site selection, feasibility studies, and licensing, which creates bottlenecks for projects attempting to reach financial close.
• A systemic, collaborative 'ecosystem approach' is required to align RBF programs with market realities. This includes the creation of 'one-stop-shop' platforms that integrate RBF grants with concessional and commercial capital and the standardization of application and reporting procedures across international funding partners.
