Summary of Formal Report 324/06: Proceedings of the International Grid-Connected Renewable Energy Policy Forum

Core Content

The International Grid-Connected Renewable Energy Policy Forum was held from February 1-3, 2006, in Mexico City, Mexico, bringing together approximately 300 participants from 35 developing and industrialized countries. The forum aimed to promote the use of grid-connected renewable energy (RE) in developing nations through the exchange of experiences, presentation of case studies, and discussion of policy instruments and financing mechanisms.

Main Objectives

• To exchange experiences and lessons on RE-friendly power sector policies between countries with successful policies and those in the process of developing them.
• To present issues, solutions, and best practices based on country-specific case studies and cross-cutting themes.
• To offer a platform for discussing collaborative opportunities and follow-up activities.

Key Themes and Topics

1. Incorporation of RE in Power Sector Frameworks

• Industrialized countries have shown that deregulating the power sector can expand services, attract private investment, and bring independent power producers (IPPs) to the market.
• A legal framework that promotes RE is essential and should be considered early in power sector reforms.
• Power sector structures influence RE market penetration: vertically integrated utilities may limit RE capacity due to monopolistic behavior, while unbundled systems allow for more flexibility and competition.
• Long-term contracts and avoiding "cookie cutter" solutions are crucial for successful RE integration.

2. Economic Valuation of RE

• Many Renewable Energy Technologies (RETs) are currently cost-competitive with conventional energy sources.
• However, technical, institutional, financing, and market barriers can hinder large-scale deployment.
• Policies, market development, and capacity building are needed to address these barriers.
• Capturing the true economic value of RE requires effective planning, recognizing its role as a hedge against fuel price volatility, and accounting for environmental and health externalities.
• A level playing field is lacking due to fossil fuel subsidies; removing these distortions is an effective policy tool.

3. RE Policy Instruments

• Three main policy instruments were discussed: Feed-in Laws, Renewable Portfolio Standards (RPS), and Tendering.
• Feed-in Laws:
  • Promote high RE penetration quickly.
  • Encourage local manufacturing and private investment.
  • Provide price certainty through guaranteed off-take prices and Power Purchase Agreements (PPAs).
  • Most simple to design and enforce.
• RPS:
  • Effective in reducing cost and price through competitive bidding.
  • Tends to favor least-cost technologies and established industry players.
  • More complex to design and administer than feed-in laws.
• Tendering:
  • Reduces cost effectively.
  • Requires mechanisms to reduce price over time.
  • Contracts must be realized to ensure success.
  • More complex than feed-in laws but simpler than RPS.

4. Private Sector Investment in RE

• A sound policy and regulatory environment is critical for private sector participation in RE.
• Long-term price predictability through transparent and adequate Power Purchase Agreements (PPAs) is essential.
• The private sector favors feed-in tariffs as the most effective policy instrument due to their guaranteed pricing.
• Administrative risks such as land acquisition and environmental safeguards can challenge RE project development.
• Risk mitigation instruments and guarantees are necessary for securing financing.
• Access to reliable resource data and grid capacity are also important technical considerations.

Key Findings and Lessons Learned

• One-sixth of global energy comes from RE, primarily traditional biomass and hydropower.
• Other RETs are growing rapidly, though from a small base.
• RE is making a difference, with 48 countries having RE policies in place, though most installations are concentrated in a few countries.
• RE "technology push" approaches are not suitable; solutions must align with local resource and market conditions.
• Commercial technologies with proven performance should be the focus in developing countries.
• There are economically viable niches for RE in most countries, especially when appropriate risk adjustment techniques are used.

Financing and Policy Instruments

• A range of financial incentives exist to support RE, including subsidies, tax credits, carbon credits, loans, and guarantees.
• Output-based incentives are generally more effective than investment-based ones in promoting RE generation.
• Common methods for covering the incremental cost of RE include:
  • Systems Benefit Charge (SBC)
  • Carbon tax on fossil fuels
  • Dedicated funds supported by governments or donors
• Local financial institutions often lack familiarity with RE projects and are hesitant to provide long-term financing due to perceived risks and high transaction costs.
• Standardized lending documents, banker training, mezzanine finance, and risk mitigation instruments can help address these issues.

Country Commitments and Follow-Up

• Several countries, including Mexico, Brazil, China, India, Denmark, Germany, the Netherlands, Spain, the UK, and the US, have made progress in large-scale RE deployment due to strong policy support.
• Other countries, such as Croatia, Egypt, Indonesia, Jordan, Nigeria, Russia, South Africa, and Tunisia, expressed interest in scaling up RE programs and replicating successful models.
• The forum emphasized the importance of collaboration between multilateral and bilateral organizations, the private sector, and research institutions to support RE development.

Next Steps

• Continued technical and financial assistance from organizations like the World Bank, ESMAP, and GEF is necessary to support RE policy development and implementation.
• The private sector and financial institutions need to be engaged through supportive policies and risk mitigation strategies.
• Research and development, along with public awareness and capacity building, are critical for the long-term success of RE projects.

Conclusion

The forum highlighted the importance of RE in promoting energy security, environmental sustainability, and economic development. It emphasized the need for tailored policy instruments, effective financing mechanisms, and a supportive regulatory environment to drive the growth of grid-connected RE. The success of RE deployment in some countries serves as a model for others, and the forum laid the groundwork for future collaboration and policy replication.
