Index Commentary

Bulgaria’s overall ranking drops four places in this year’s Index, although it sees minimal change across both energy and contextual indicators. The competing dimensions of the energy trilemma continue to be unbalanced, as Bulgaria has a high level of energy security, a mediocre amount of energy equity, and does a poor job in mitigating its environmental impact. Energy security, the strongest of all dimensions, improves as the country further increases its reserve oil stocks. The electricity fuel mix remains well-balanced, using a diverse mix of conventional thermal, nuclear, and renewable sources. Energy equity performance remains lackluster, with comparatively high levels of household spending on electricity services. Environmental sustainability remains Bulgaria’s weakest dimension, with high energy and emission intensity, comparatively poor air and water quality, and high CO2 emissions from electricity generation. Overall contextual performance is stable, as improvements in macroeconomic stability and the education system are offset by slight declines in most other contextual indicators.

Trends and Outlook

In July 2012 the Bulgarian Parliament amended the existing Energy Act to: guarantee equal access to electricity and gas grids; strengthen the power of national energy regulators; improve market transparency; promote trans-border trade; and enhance end-user rights. The new legal framework is expected to improve the sustainable use of renewable energy sources, market liberalization and social equity.

Key issues policymakers need to focus on are: 1) improve energy security by building a reliable energy infrastructure, further diversifying sources and routes of energy supply, and optimizing the use of indigenous energy resources; 2) increase energy efficiency; 3) promote clean development mechanisms; 4) social protection; and 5) pursue the ambitious targets of giving 30% of households access to natural gas by 2020 as set out in the national energy strategy.
