AC-Freileitung:
380-kV HTLS-Parallelneubau (Doppelleitung, 2 Stromkreise) 4,7 Mio. EUR / km
380-kV Neubau in neuer Trasse (Doppelleitung, 2 Stromkreise) 4,5 Mio. EUR / km

DC-Erdkabel:
320-kV Neubau in neuer Trasse (1 GW ohne metallischen Rückleiter) 3,5 Mio. EUR / km
525-kV Neubau in neuer Trasse (2 GW mit metallischem Rückleiter) 7,6 Mio. EUR / km
525-kV Neubau in neuer Trasse (2 GW) 6,6 Mio. EUR / km
3500 EUR/MW/km
3800 EUR/MW/km
3300 EUR/MW/km
Assumptions for retrofit suggest similar cost of AC-Freileitung and DC-Freileitung.
Underground assumptions could also be used for submarine assumptions.

OverHead Lines (OHL) are not included in the new cost
model, as only a few HVDC overhead lines are being built
or planned in Europe
Rating of 2.2 GW
submarine:
1.061 M€/GW/km
2.784 M€ assuming 2.2 GW and 100km length
0.248 M€/km / 2.2 GW
1061 €/MW/km + 112.72 €/MW/km + 12.65 €/MW/km = 1159.37 €/MW/km
underground
0.672 M€/GW/km
2.784 M€ assuming 2.2 GW and 100km length
0.408 M€/km / 2.2 GW
672 €/MW/km + 185.45 €/MW/km + + 12.65 €/MW/km = 870.1 €/MW/km
