Case Studies of Power Sector Reform in Developing Countries

This report analyzes the restructuring of Bulgaria's power sector around 2000, detailing the transition from a state monopoly (NEC) to a 'Single Buyer' model with independent producers and distributors. It highlights the heavy influence of the IMF and World Bank, the failure to implement a fully transparent regulatory framework, and the social strain on low-income households. Key technical data includes a total capacity of 12,668 MW, dominated by thermal (51.7%) and nuclear (29.7%) power. The report also notes Bulgaria's GHG emission targets under the Kyoto Protocol and the critical state of its district heating systems.

• The Bulgarian power sector underwent a structural reform starting in April 2000, transforming the National Electric Company (NEC) from a vertically integrated monopoly into a national power transmission company acting as a "Single Buyer" and exporter. Seven new state-owned joint-stock companies for power distribution and three independent power generation companies, including the Kozloduy Nuclear Power Plant, were separated from the NEC.
• As of the report's data, Bulgaria's installed electricity generation capacity totaled 12,668 MW. Thermal Power Plants (TPP) accounted for the largest share at 51.7% (6,556 MW), followed by Nuclear Power Plants (NPP) at 29.7% (3,760 MW), Hydro Power Plants (HPP) at 15.2% (1,920 MW), and Pumping HPPs at 3.4% (432 MW).
• The International Monetary Fund (IMF) and World Bank played significant roles in driving the reform. The IMF provided financial support through a 3-year agreement signed in May 1997 for 627.62 million SDR, which required the implementation of energy sector reforms, the establishment of independent economic entities, and the removal of state subsidies.
• The report identifies a pricing disparity where domestic consumers, particularly households, effectively subsidize electricity exports. NEC exported power to Turkey, Greece, Serbia, and Kosovo at prices between 30 and 35 USD/MWh, while domestic industry paid higher rates (e.g., 4.0 cents/kWh compared to 3.0-3.5 cents/kWh for exports).
• The reform process was characterized by a lack of transparency and the exclusion of various stakeholders. The final decision to launch the reform in May 2000 was made by the Prime Minister and the President of the State Agency for Energy and Energy Resources (SEERA), despite objections from the IMF, World Bank, and EBRD regarding the lack of an approved regulatory framework.
• Significant social burdens are associated with energy costs, particularly for low-income households. Approximately 38% of Bulgarian households are low-income, spending 14% of their income on energy, with many living below the UN poverty threshold of USD 2/day.
• The district heating (DH) sector faces a crisis where half of the subscribers have resigned due to an inability to pay. While the World Bank provided a loan for the modernization of DH systems in Sofia and Pernik, the Bulgarian government postponed its application due to concerns over state guarantees and potential privatization.
• Bulgaria has international commitments to mitigate greenhouse gas (GHG) emissions, including a target under the Kyoto Protocol for an 8% reduction based on 1988 emission levels for the period 2008-2012. The report notes that Bulgaria is currently closer to a general reduction scenario due to deep structural changes in industry and high energy prices limiting consumption.
