WebWhile that is the case, investments large enough to shift the energy landscape in favor of renewables will prove difficult. Even in China, HVDC projects had an installed capacity of 119.7 GW in 2024, compared with a forecasted energy demand above 1200 GW, meaning that HVDC lines carry less than 10% of the country's electricity. [15] Web18 nov. 2024 · An HVDC link is two rectifier/inverter stations connected by an overhead line or DC cables. Bipolar HVDC line uses only two insulated sets of conductors rather than three. This results in narrower rights of way, smaller transmission towers. For a given cable conductor area, the line losses with HVDC cables is about 50% of that AC cables.
