Summary of Report No. 53719-PE: Overcoming the Barriers to Hydropower in Peru

Core Content

This report, prepared by the World Bank's Energy Sector Management Assistance Program (ESMAP), evaluates the role of hydropower in Peru's energy sector and identifies the key challenges and opportunities for its development. It provides a comprehensive analysis of the technical, economic, and financial viability of hydropower projects, alongside an assessment of the regulatory and legal frameworks that support their development.

Main Objectives and Background

• Objective: To assess the potential contribution of hydropower to Peru's energy mix and to recommend measures to encourage its development.
• Background: Hydropower has traditionally supplied over 80% of Peru's electricity. However, the rise of natural gas as a cheaper alternative led to a decline in hydropower's share. Recent developments, including climate change concerns and energy security, have renewed interest in hydropower.

Technical Viability of Hydropower

• Hydropower Potential: Peru has significant hydropower potential, especially in the western basins, with projects totaling over 1,000 MW with definitive concessions.
• Challenges:
  • Limited hydrological data and analysis.
  • Social and environmental concerns.
  • Climate change impacts, particularly on rainfall patterns and glacier recession.
• Adaptation Measures: Projects that rely on glacier-fed water can be adapted, but the broader impacts of climate change require more research and planning.
• Conclusion: Hydropower is technically viable, especially for low-impact run-of-river projects, and can contribute to a low-carbon economy.

Economic Rationale

• Natural Gas Prices: Natural gas prices in Peru are among the lowest in the region, creating a price distortion that disadvantages hydropower.
• Economic Cost of Gas: At an average crude oil price of $75 per barrel, gas is valued at around $4.4 per mmBTU, making it less economically attractive compared to hydropower.
• Cost Comparison:
  • Hydropower is about 1 US cent per kWh cheaper than gas-based generation.
  • Economic analysis shows that hydropower projects are viable if gas prices are at their economic level.
• Impact of Gas Price: At the current low gas price (US$2.14/mmBTU), few hydropower projects are financially competitive.
• Benefits:
  • Local and global environmental benefits from reduced emissions.
  • Potential for export in eastern basins, where hydropower potential exceeds domestic demand.

Financial Viability

• Financing Scenarios:
  • Commercial Finance: High energy prices due to limited loan terms.
  • Project Finance: More favorable due to longer loan tenors.
  • Development Bank Financing: Offers lower interest rates, reducing financing costs.
  • Blended Finance: Combines IFI and commercial bank support, reducing total financial price by up to 25%.
  • Public Sector Projects: May have higher risks but can benefit from IFI financing.
• Key Factors:
  • Interest rates and loan terms significantly impact financial viability.
  • Carbon finance can improve the economic rate of return (ERR) of hydropower projects.
  • Financial risks include price, completion, hydrology, operational, and off-take risks.
• Impact of Financial Crisis: The global financial crisis has made financing more difficult, with interest rates and liquidity fluctuating rapidly.

Enabling Framework

• Licensing and Water Rights:
  • Hydropower projects require definitive concessions and water rights.
  • Current procedures are fragmented and need streamlining.
• Regulatory System:
  • The electricity sector is transitioning through new policies and regulations.
  • The auction system is being reformed to support hydropower development.
• Key Recommendations:
  • Accelerated depreciation for hydropower.
  • Introduction of discounts to allow hydropower to compete in auctions.
  • Special hydropower auctions to promote investment.

Barriers to Development

• Price Distortion: Low natural gas prices make hydropower less competitive.
• Inefficient Policy: Government incentives for renewables (e.g., premiums, exclusive auctions) are used to counteract gas price distortion, which may not be sustainable.
• Regulatory Uncertainty: Recent changes in policy and regulation create an unstable environment for investment.
• Financial Challenges: Limited access to financing due to global market instability.
• Environmental and Social Concerns: Projects in eastern basins face greater environmental and social impacts.

Policy Recommendations

• Stronger Role of the State: The government should play a more active role in promoting hydropower through coherent policies.
• Develop Amazon Basins for Exports: Eastern basins offer export potential to neighboring countries like Brazil.
• Improve Data and Monitoring: Enhance hydrometeorological data collection and monitoring.
• Support for Financing: Encourage blended finance models that combine IFIs and commercial banks to reduce costs.
• Adaptation Strategies: Implement measures to adapt to climate change impacts, such as increased storage capacity and monitoring of glacier recession.

Conclusion

• Hydropower remains a critical component of Peru's energy strategy, particularly in the context of climate change and energy security.
• Despite its technical and economic potential, hydropower development is hindered by low gas prices, regulatory uncertainty, and financial risks.
• A coherent and sustainable policy framework, along with improved financing mechanisms and data collection, is essential for the continued development of hydropower in Peru.
