OBA in Infrastructure: The Experience So Far

Core Content

Output-Based Aid (OBA) is a results-based financing (RBF) approach that aims to improve access to basic infrastructure services for poor and marginalized populations. By linking payments to verified outputs, OBA ensures quality and accountability in service delivery while promoting the inclusion of underserved communities. This paper reviews the experience of OBA in infrastructure projects, highlighting its effectiveness, financial leverage, and broader impacts.

Main Points

1. How OBA Works

• OBA supports service providers by paying for outputs once they are delivered and verified.
• Independent verification agents (IVAs) monitor implementation and ensure performance.
• GPOBA has implemented 48 projects across six sectors, reaching over 9 million people since 2006.
• OBA has mobilized $239 million in total, with $199 million allocated to infrastructure projects.
• For every dollar invested, OBA has leveraged an additional $2.4 in financing from various sources.

2. How OBA Reaches the Poor

• Traditional subsidies often fail to reach the poor, who are not connected to infrastructure networks.
• OBA targets poor populations specifically, ensuring that investments in infrastructure benefit those most in need.
• Subsidies can cover capital costs or interest on loans, as seen in Ethiopia's electricity project.
• Targeting methodologies are tailored to the project and context, including geographic, means-tested, and poverty mapping approaches.

3. Leveraging Private and Domestic Finance

• OBA encourages the use of private sector financing, domestic resources, and development partner contributions.
• In Kenya, a $2.6 million grant catalyzed $3.4 million in commercial loans and $1.2 million in community equity.
• In Honduras, $4 million in OBA subsidies led to $3 million in additional financing from various stakeholders.
• In Morocco, a $7 million grant was leveraged to $30 million in public and private financing.
• In Ghana and Bangladesh, OBA supported the development of renewable energy markets and local expertise.

4. Building Institutional and Technical Capacity

• OBA projects enhance local institutional and technical capabilities, often through partnerships with governments, NGOs, and private entities.
• Technical assistance (TA) is a key component, helping to design and implement subsidy projects.
• Examples include:
  • Kenya: KPLC and GPOBA improved performance and trust in slum areas.
  • Mali: AMADER received support to restore technical and monitoring capacities after conflict.
  • Nepal: Municipalities gained technical expertise in waste management.
  • Bangladesh: IDCOL trained technical staff from ten countries.
  • Liberia: A willingness-to-pay analysis informed expansion plans for the electricity sector.

5. Developing Local Markets and SMEs

• OBA has positive spin-off effects on local economies, including job creation and SME development.
• In Senegal, the sanitation project supported local artisans and improved product quality.
• In Ghana, OBA helped develop a standardized solar PV market, reducing costs and increasing vendor interest.
• In Kenya, water projects promoted small-scale enterprises by enabling productive uses of water.
• Energy projects have also supported income generation through extended operating hours and new activities.

6. Cross-Cutting Impacts

• OBA contributes to climate change mitigation through renewable energy solutions.
• It improves quality of life, especially for women and children, by reducing time spent on household chores and improving health conditions.
• Examples include:
  • In Ethiopia and Bangladesh, electrification reduced indoor pollution and improved study conditions.
  • In Andhra Pradesh, piped water projects significantly reduced water-borne diseases.

Key Information

• Total GPOBA Investment: $239 million
• Infrastructure Investment: $199 million (75% of total)
• Beneficiaries: Over 7.5 million people
• Leverage Ratio: 2.4 (for every $1 invested, $2.4 is leveraged)
• Sectors Covered: Energy, water/sanitation, solid waste management, telecoms

Conclusion

OBA has demonstrated strategic relevance in infrastructure development, particularly in poor and marginalized communities. It has enabled the expansion of basic services, built local capacities, leveraged private and domestic finance, and generated cross-cutting benefits such as improved health, education, and environmental sustainability. As demand for results-based approaches grows, GPOBA continues to scale and mainstream OBA across multiple sectors and countries, supporting sustainable development and poverty reduction.
