Summary of Stuck in Transition: Reform Experiences and Challenges Ahead in the Kazakhstan Power Sector

Core Content

This report by the World Bank, authored by Mirlan Aldayarov, Istvan Dobozi, and Thomas Nikolakakis, examines the challenges and reform experiences of Kazakhstan's power sector. It provides an in-depth analysis of the sector's current state, outlines key challenges, and presents several development scenarios to guide future policy decisions.

Main Sector Challenges

• High Energy Intensity: Kazakhstan's GDP has a very high energy intensity, placing significant pressure on the power infrastructure.
• Supply Security Risk: The reserve margin has declined sharply from 53% in 2000 to 4% in 2012, indicating a growing risk of supply shortages.
• Investment Needs: The power sector requires substantial investment, with undiscounted annual capital expenditure ranging from US$54.6 billion to US$96.2 billion between 2015 and 2045.
• Ineffective Regulation: Administrative measures since the mid-2000s have reversed market-oriented reforms, harming the investment climate and competition.
• Tariff and Market Issues: The government has intervened in the market, leading to a lack of effective pricing mechanisms and a decline in market efficiency.

Key Sector Reforms and Market Structure

• Kazakhstan adopted a liberalized multimarket model early on, including bilateral, spot, balancing, ancillary, and capacity submarkets.
• The government initially supported a functioning electricity spot market, which supplemented bilateral contracts.
• However, recent reforms have introduced restrictions on the spot market, eliminated zonal transmission tariffs, and postponed the real-time balancing market.
• The sector has experienced a shift towards renationalization and oligopolization, which has limited competition and private investment.

Sector Development Scenarios

Four main scenarios were analyzed to model the future of the power sector:

1. Base Case: Assumes continuation of current policies and investment projects. It focuses on optimizing generation and transmission based on existing conditions.
2. Green Case: Aims to promote energy efficiency and reduce demand growth, particularly peak demand. It is aligned with Kazakhstan's Green Economy Concept.
3. Regional Export Case: Focuses on increasing export capacity while maintaining full electricity independence. It aligns with the Energy Concept 2030.
4. Least-Cost Case: An extreme benchmark scenario that prioritizes cost-effectiveness, using least-cost principles for system expansion and operation.

Key Findings

• The systemwide levelized cost of electricity (LCOE) is a key metric used in the analysis, reflecting the average total cost of building, rehabilitating, and operating generation assets and interzonal transmission over the planning horizon.
• The Base Case scenario results in a systemwide LCOE of $35.1/MWh, with total undiscounted annualized capital expenditure of $81.56 billion.
• The Green Case scenario, which emphasizes energy efficiency, leads to a higher LCOE of $41.5/MWh but reduces CO₂ emissions by 40% compared to 2012 levels.
• The Regional Export Case scenario has a slightly lower LCOE of $34.8/MWh, with total undiscounted annualized capital expenditure of $83.36 billion.
• The Least-Cost Case scenario, which focuses on minimizing costs, yields the lowest LCOE of $31.1/MWh and the lowest capital expenditure of $54.62 billion.

Cost and Affordability Analysis

• The average residential electricity tariff would need to increase by 40–55% to reflect the LCOE.
• Despite this, the affordability analysis confirms that electricity remains generally affordable.
• The study highlights the importance of balancing cost, efficiency, and environmental impact in the sector's development.

Recommendations

• The report recommends a shift towards more effective regulation and market-oriented reforms.
• It suggests the implementation of a market-based pricing mechanism to reflect supply and demand gaps.
• The promotion of renewable energy integration and energy efficiency programs is emphasized.
• Investment in generation and transmission infrastructure is crucial, with a focus on cost-effective technologies.
• The report advocates for increased private sector participation and improved transparency in the sector.

Conclusion

Kazakhstan's power sector has undergone significant transformation since the 1990s, but many reforms remain incomplete. The report underscores the need for continued investment, regulatory reform, and market liberalization to ensure long-term sustainability, affordability, and environmental responsibility. The four scenarios model different pathways for the sector's development, highlighting the trade-offs between cost, efficiency, and environmental impact. The findings suggest that the Least-Cost Case offers the most economically viable path, but it must be balanced with environmental and social considerations.
