Who regulates

Who controls the grid

SEPS, owned by the state, runs transmission; three regional companies run distribution.

Markets & power exchanges

Regional grid

  • ENTSO-E · Continental European gridRegional grid

    Part of the synchronous grid of Continental Europe, the largest interconnected grid in the world by customers, coordinated by the European Network of Transmission System Operators for Electricity.

What does “Liberalised market” mean?

Generators sell into a wholesale market, an independent operator runs the transmission grid, and households can choose their electricity supplier. Networks stay regulated monopolies because building parallel power lines makes no sense.
