Summary of "Review of Electricity Supply and Demand in Southeast Europe"

Core Content

This working paper provides an analysis of electricity supply and demand in Southeast Europe (SEE), focusing on the period from 1991 to 2012. It is part of a broader initiative to establish a regional electricity market (SEEREM) supported by the European Commission and the World Bank. The study aims to assess the current and future electricity balance in the region, identify investment needs, and explore opportunities for reducing those needs through energy efficiency and increased regional trade.

Main Objectives

• Review electricity supply and demand in the SEE region over the past decade (1991–2001).
• Forecast electricity demand and supply up to 2012.
• Identify the investment requirements for generation expansion and the potential benefits of regional coordination.
• Assess the role of energy efficiency and trade in reducing the need for new generation capacity.

Key Findings

Electricity Supply and Demand (1991–2001)

• The region had an installed power generation capacity of about 49.5 GW in 2001, composed of 35% hydro, 55% thermal, and 10% nuclear.
• However, the average age of the power plants exceeded 30 years, and some were older than 40 years, leading to declining reliability.
• In 1991, the region’s gross generation was 167 TWh, sufficient to meet the demand of 147 TWh. By 2001, the region faced a supply deficit, with demand exceeding available capacity in Serbia, Montenegro, and Albania, resulting in load shedding.
• Regional electricity consumption grew at an annual rate of 1% between 1991 and 2001, while peak load grew at 2.2% per annum, reflecting GDP growth and fuel substitution to electricity for heating.
• The electricity consumption per capita in the region was 2200 kWh, significantly lower than the European average of 0.19 toe per $1000 GDP.

Electricity Demand and Supply Outlook (2002–2012)

• Regional electricity demand is expected to grow at a rate of 2.3% per annum, reaching 214 TWh by 2012.
• Peak load is projected to increase to 38.2 GW by 2012, representing a 6,800 MW increase from 2001.
• The region expects to add about 4,500 MW of net new capacity by 2012 to meet demand.
• The study highlights that the current investment plans are based on national self-reliance and do not fully account for the potential benefits of regional coordination, such as shared capacity reserves and non-coincidental peak demand.

Investment Requirements

• The proposed generation expansion plans would require financing of about $5 billion through 2012.
• Rehabilitation of aging infrastructure is also expected to be a significant investment.
• The current investment climate is not conducive to attracting private sector investment, and the public sector lacks long-term financial capacity.

Strategic Options and Priorities

• Energy Efficiency: The region has significant potential to improve energy efficiency, particularly in the power sector. Energy efficiency improvements could reduce the need for new generation capacity and load shedding.
• Regional Trade: Increased electricity trade among SEE countries and with external partners like Greece and Turkey could reduce investment needs by optimizing resource use and load management.
• Institutional Reform: To enable regional integration, institutional reforms are necessary, including unbundling of utilities, setting up independent regulators, and developing market mechanisms and financial settlement systems.
• Technical Infrastructure: Investment in transmission infrastructure is essential to remove bottlenecks and expand interconnections to facilitate greater trade.

Institutional and Technical Barriers

• Institutional: Many countries lack the regulatory framework to support a competitive electricity market. The SEEREM initiative aims to address this by promoting institutional reforms.
• Technical: The transmission network in the region has bottlenecks that hinder trade. New lines within and between countries are needed to improve grid connectivity and system stability.

Regional Electricity Market (SEEREM)

• SEEREM is a regional initiative to integrate electricity markets in the SEE countries, aiming to align with the EU's Internal Electricity Market.
• The market is expected to improve system security, reduce costs, and increase efficiency through coordinated planning and trade.
• The World Bank and the European Commission are collaborating on a regional least cost expansion plan as a follow-up to this study.

Conclusion

• The region faces a growing electricity supply deficit due to aging infrastructure and increasing demand.
• A coordinated regional approach, emphasizing energy efficiency and expanded trade, could significantly reduce the need for new generation capacity.
• Institutional and technical reforms are essential to realize the benefits of a regional electricity market.
• The study provides a foundation for future regional planning and investment in the energy sector.
