The macro-economic situation of the country is characterised by the GDP, which indicates significant variations. Starting from 1990 the annual overage growth of GDP becomes negative. In 1997 an structural adjustment program was launched, accelerating market reforms in almost all sectors of economy. A top priority of the energy policy is expansion of the production of energy resources based on anticipated minimum costs and demand side management, as well as storage facilities. The coal resources are poor in quality and are depleting The coal-based electricity generation will be maintained in the near future.
Pit coal is produced in underground mines.
Generally, the coal-mining technology is obsolete. The highest crude oil output of the country was obtained in 1976 when 14.7 Mt of oil were produced and the highest natural gas output, amounting to 39.4 Bcm, was obtained in 1986, after which a dramatic decline followed. In 1997 6.5 Mt of oil and 15.3 Bcm of gas were produced. Investigations will be intensified in the future for oil drilling at a depth of more than 4,000 m, particularly in the off-shore platform in the Black Sea. The uranium resources of the country are limited.
