Romania energy strategy 2016-2030

Primary Energy Sources: Domestic Production and ImportsPrice Impact on InvestmentsEstimates For 2030-2050Periodical Updates of The Energy StrategyRegarding crude oil, the low price on the international market has drastically cut, in the past two years, the investments in exploration and in the development of new deposits and the effect is fully felt in Romania, the document reads. Although the gradual recovery of oil prices is likely and, consequently, the partial recovery of investments in the sector, Romania’s oil production is on a downward trend, with a low level of reserves’ replacement due to the high degree of depletion of deposits. The increase of the recovery rate is possible, but the investments are substantial and require specific regulatory framework. Only the discovery of new deposits can sustain the current level of activity in the oil sector. The modelling results show the halving of domestic oil output to about 2 million tons in 2030. Over medium and long term, the higher dependence on imports can be avoided only by encouraging the exploration and production operations, with increased efficiency in fuel consum...Get price
