How has Moldova restructured its electricity distribution network?

As part of the reforms, Moldova restructured and partially privatized its electricity distribution network, including Premier Energy, a private company that controls 70 percent of the country's electric distribution grid.

Does Moldova have an electricity power system?

Moldova's electricity power system operates in parallel with Ukraine's (the Integrated Power System / Unified Power System of Russia grid), but it cannot currently operate in parallel with Romania's network, which is part of ENTSO-E. Only small quantities of electricity can be exchanged between the two systems through an island-mode operation.

Does Moldova have energy security?

Despite acceptable energy security levels in Moldova in 2019, the country faces exposure to gas supply shock risks due to its reliance on Russia for all of its gas via Ukraine. Two major supply disruptions occurred in 2006 and 2009 due to disputes between the two countries.

How does Moldova share energy data?

Moldova shares energy data through five annual International Energy Agency (IEA)/Eurostat/UN Economic Commission for Europe (UNECE) joint questionnaires.
