Understanding electricity markets in the EU
www.europarl.europa.euTransmission networks are networked grids of long-distance power lines. High voltages, between 220 kV and 1 000 kV, are used for reducing transmission losses. Traditionally, transmission networks use alternating current (A C), but high-voltage direct current (HVDC) is emerging as an effective alternative.6 The European transmission grid
