Romania’s energy sector needs as much as 30 billion euros ($34 billion) of investment in power, oil and gas production, mining and related infrastructure by 2030 to replace outdated plants and meet rising demand, a draft energy strategy showed on Thursday.

The European Union state is one of the bloc’s most energy-independent countries as a net exporter of power, although it has to import oil and about 10 percent of its gas needs, according to Reuters.

The 2019-2030 energy strategy draft, for which the energy ministry is awaiting feedback by the end of this month, looks at investment in gas and power networks, interconnections and energy production.

The investment needs are estimated at 15 to 30 billion euros by 2030, with an additional 15 billion potentially needed between 2031-2050, the draft said.
