Summary of the Report: Small Hydro Power Plant in the Kyrgyz Republic - Assessment of Potential and Development Challenges

Core Content

This report, prepared by the World Bank and IFC, evaluates the technical potential, economic and financial viability, and regulatory challenges of small hydro power plants (SHPPs) in the Kyrgyz Republic. It aims to support the development of SHPPs by analyzing their cost relative to alternatives, assessing the feed-in tariff (FiT) mechanism, and reviewing the legal and regulatory framework.

Main Points

1. Sector Background

• SHPP development in the Kyrgyz Republic began during the Soviet era with over 150 SHPPs operating.
• Most were decommissioned when the large Toktogul HPP was commissioned in the 1970s and the national grid was extended.
• The first SHPP was transferred to a private operator in 1997, marking the start of privatization efforts.
• The 1999-2005 SHPP Development Program and the 2000-2012 Program for Small and Medium Hydropower aimed to promote SHPPs but were not fully realized due to various barriers.
• In 2015, the Kyrgyz Republic approved a new Concept for SHPP Development, and started improving the legal and regulatory framework.

2. Technical Potential

• There are currently 15 SHPPs in operation, totaling 46 MW.
• Earlier estimates suggest that SHPPs could generate between 5 to 8 billion kWh annually.
• However, these estimates are considered outdated and unreliable.
• More recent studies by UNDP and UNIDO suggest 87 to 92 potential SHPP sites, with a total installed capacity of about 180 MW and an average capacity factor of 63%.
• The SHPP sites were classified into three tiers based on the level of detail in the studies:
  • Tier 1: Sites with detailed feasibility studies.
  • Tier 2: Sites with reasonable cost breakdowns.
  • Tier 3: Sites with minimal information.
• The total installed capacity of Tier 1 and Tier 2 sites is 409 MW, which could generate approximately 2.1 billion kWh annually.

3. Cost Analysis

• The report estimates the Levelized Cost of Energy (LCoE) for SHPPs in economic and financial terms.
• Economic Analysis includes external costs (e.g., CO₂ emissions) and social opportunity costs, and compares SHPP costs to alternatives such as Bishkek CHP and imports.
• Financial Analysis excludes external costs and uses different capital opportunity costs to reflect private investor expectations.
• The economic supply curve shows that 45% of SHPP generation potential is below the lower-end import cost, and 97% is below the high-end import cost.
• The financial supply curve indicates that 14% of SHPP generation is financially viable under the 2016 FiT, increasing to 19% with a 10-year offtake and 28% with a 15-year offtake.

4. Feed-in Tariff (FiT) Analysis

• The FiT for SHPPs is calculated using a formula established by the Kyrgyz Republic's energy regulator.
• The formula is:
  $$
  T = T_1 \times k_0
  $$
  Where:
  • $T$ is the calculated tariff (in KGS/kWh).
  • $T_1$ is the maximum end-user tariff (2.24 KGS/kWh).
  • $k_0$ is a coefficient for hydropower, set at 2.1.
• The 2015 FiT methodology included partial indexation to inflation and exchange rate fluctuations.
• The revised 2016 FiT formula:
  $$
  T = TM \times K
  $$
  Where:
  • $TM$ is the maximum tariff.
  • $K$ is a coefficient.
• The report highlights that the length of the offtake period significantly affects financial viability.

5. Fiscal and Financial Burden

• SHPPs impose a fiscal burden on the Government of Kyrgyz Republic (GoKR) and end-use customers.
• The financial cost of SHPP generation is compared to the current FiT and the economic costs of Bishkek CHP.
• The report suggests that tariff indexation is a key factor in improving the financial attractiveness of SHPPs.

6. Phasing and Sequencing of SHPP Development

• Recommendations are made for the phasing and sequencing of SHPP projects based on cost, capacity, and regulatory environment.
• Priority sites are identified, with the aim of maximizing the financial and economic benefits of SHPP development.

7. Policy and Legal Framework

• The legal and regulatory framework for SHPPs is analyzed in detail.
• Key challenges include:
  • Lack of clarity and consistency in legal provisions.
  • Inadequate procedures for site selection, registration of water and land rights, and grid connection.
  • Inconsistent tariff indexation and off-taker creditworthiness.
• Recommendations include improving legal clarity, streamlining administrative procedures, and enhancing the enabling environment for private investors.

8. Regulatory Processes

• The report outlines the administrative and regulatory processes required for SHPP development, including:
  • Site selection and project preparation.
  • Registration of water and land use rights.
  • Grid connection and commissioning.
  • Operation and maintenance.
• It provides examples of best practices from international experience and highlights the need for improved regulatory efficiency.

Key Information

• Total installed capacity of SHPPs in operation (2016): 46 MW.
• Estimated SHPP generation potential: 5 to 8 billion kWh annually.
• Tier 1 and Tier 2 sites: Total of 409 MW, with potential generation of 2.1 billion kWh per year.
• FiT for SHPPs (2016): 0.07 USD/kWh.
• Financial viability under different offtake periods:
  • 8-year offtake: 14% of SHPP generation is viable.
  • 10-year offtake: 19% of SHPP generation is viable.
  • 15-year offtake: 28% of SHPP generation is viable.
• Key challenges:
  • Inadequate legal and regulatory framework.
  • Lack of indexation of tariffs to inflation and exchange rate fluctuations.
  • Barriers to private investment, including unclear ownership and poor creditworthiness of off-takers.
  • Insufficient local expertise and infrastructure for SHPP design, construction, and operation.

Conclusion

The report concludes that while the Kyrgyz Republic has significant potential for SHPP development, the current regulatory and financial environment poses substantial challenges. The analysis provides a foundation for policy improvements, including the development of a more favorable FiT mechanism, streamlining of administrative procedures, and enhancing the creditworthiness of off-takers. These changes are essential for attracting private investment and ensuring the long-term sustainability of SHPP projects in the country.
