Armenia Power Sector Policy Note Summary

Core Content

This document outlines the key challenges and proposed solutions for Armenia's power sector, emphasizing the need for policy reforms and investments to ensure supply adequacy, security, and affordability. It is a World Bank report prepared in December 2014, based on data from Armenian energy companies, the Public Service Regulatory Commission, and discussions with the Ministry of Energy and Power System Operator.

Main Challenges

1. Supply Adequacy

• The Hrazdan TPP, the highest-cost and most dilapidated power plant, will need to operate beyond 2016 to prevent a supply gap.
• Only 45% of hydro capacity is available during winter peaks.
• New lower-cost CCGT plants cannot be realistically constructed before 2020.
• Current tariff structure encourages over-consumption during winter and unnecessary gas use by public and commercial facilities.
• The gas tariff structure creates perverse incentives for end-users to over-consume to benefit from lower wholesale prices.

2. Supply Security

• Several transmission lines and substations are in poor condition, leading to high outage rates.
• The HVEN lacks a methodology for prioritizing transmission investments.
• Critical transmission assets, such as the Echmiadsin and Shahumyan-2 lines, are essential for system reliability and safety.
• The absence of an operational back-up dispatch center poses a risk to emergency response.

3. Affordability

• Energy costs have increased, with household energy expenses reaching 10% of total expenditure, indicating energy poverty.
• Tariff increases in 2013 contributed to a 3% rise in poverty.
• The poor are disproportionately affected, with energy expenses rising to 13.6% of their budgets.
• Without subsidies, the energy share for the poor would have increased by 15.7%.
• Gas-based heating is declining, while wood-based heating is increasing, with negative long-term impacts on public health and forest resources.

Proposed Solutions

1. Supply Adequacy

• Add new generation: Focus on a 500 MW gas-fired plant by 2020 and another by 2026. Other supply plans also require new gas plants.
• Rehabilitate key transmission assets: Prioritize substation and transmission line rehabilitation based on a risk index that considers failure probability and consequences.
• Revise tariff structure: Implement a two-part seasonal and time-of-day tariff system to reflect marginal costs and reduce peak demand.
• Promote energy efficiency: Conduct a comprehensive study to estimate energy efficiency potential and mandate energy efficiency in new construction and renovation projects.
• Support the poor: Top up social assistance programs to ensure basic energy consumption remains affordable.

2. Supply Security

• Develop a risk assessment methodology: Use a risk index based on asset condition, outage history, and potential consequences to prioritize transmission investments.
• Rehabilitate critical assets: High-priority lines and substations, such as Sevan, Echmiadsin, Shahumyan-2, and the Metsamor substation, require urgent attention.
• Improve dispatch capabilities: Establish an operational back-up dispatch center for emergency situations.

3. Affordability

• Implement cost recovery tariffs: Ensure tariffs reflect actual costs to support financial sustainability of power companies.
• Subsidy trade-offs: Consider lifeline tariffs through existing programs for targeted support, while balancing coverage and incentives for energy efficiency.
• Promote renewable energy: Include Shongh and Loriberd HPPs in the LCP. Geothermal may also be part of the LCP if high-temperature resources are found.

Key Information

• LCP (Least Cost Plan): The most cost-effective solution for supply adequacy, with a focus on gas-fired generation.
• Gas Pipeline Capacity: Current capacity is sufficient, but increased imports from Iran are necessary for LCP feasibility.
• Nuclear Options: A medium NPP may be more cost-effective than a large NPP due to lower capital costs and no surplus capacity.
• Energy Efficiency: Projects like the WB/GEF Energy Efficiency Program have shown savings of up to 52% in schools and hospitals, with payback periods of 4–6 years.
• Regional Trade: Short-term trade opportunities are limited due to political issues and lack of infrastructure. Long-term export potential is unlikely due to high costs and competition from neighboring countries.

Financial and Implementation Considerations

• Financing New Investments: The LCP can be financed with public debt, but private sector participation (e.g., PPPs) is recommended for sustainability.
• Construction Timeline for New CCGT: The GoA must start the project by February 2015 to ensure commissioning by 2020.
• Tariff Impacts on Poverty: The LCP has the lowest impact on poverty compared to other scenarios, as it assumes commercial financing and reflects marginal costs.

Conclusion

To ensure the long-term sustainability and reliability of Armenia's power sector, the government must prioritize investment in new generation and transmission infrastructure, revise tariff structures to reflect true costs, and support the poor through targeted social assistance programs. Energy efficiency initiatives and regional trade opportunities should also be explored to reduce costs and improve supply security.
